University of Massachusetts

The University of Massachusetts is the five-campus public university system and the only public research system in the Commonwealth of Massachusetts. The university system includes five campuses (Amherst, Boston, Dartmouth, Lowell, a medical school in Worcester and a law school in Dartmouth), a satellite campus in Springfield and also 25 campuses throughout California and Washington with the University of Massachusetts Global.

The University of Massachusetts system is governed by a president and a 22-member Board of Trustees, which functions as a legislative body. The system administration is in Boston and Shrewsbury, is accredited by the New England Association of Schools and Colleges, and across its campuses enrolls 73,979 students.

Campuses
The University of Massachusetts Amherst is the largest school in the UMass system. It was also the first one established, dating back to 1863, when it was founded as the Massachusetts Agricultural College. The University of Massachusetts Chan Medical School was founded in 1962, and is located in Worcester. The University of Massachusetts Boston, originally established in 1964, was merged with Boston State College in 1982. In 1991, the University of Lowell and Southeastern Massachusetts University joined the system as the University of Massachusetts Lowell and University of Massachusetts Dartmouth, respectively.

University of Massachusetts Amherst

Amherst is the flagship and the largest of the UMass campuses, as well as the first established. Like many colleges and universities, the Massachusetts Agricultural College (as it was originally called) in Amherst was founded as a land-grant college in 1863, receiving initial start-up funding as part of the Morrill Land-Grant Colleges Act. It became "Massachusetts State College" in 1931, and "University of Massachusetts" in 1947. The library system is the largest state-supported library system in New England with over 6.1 million items. The campus has many architecturally distinctive buildings commissioned by the Commonwealth and designed by world-renowned architects.

Massachusetts offers a variety of academic and co-curricular options. Ninety-two percent of the more than 1,300 full-time faculty members hold the highest degree in their fields. The average SAT score for the 2018 entering class is 1296, and the average GPA is 3.90 on a 4.0 scale. The campus has 21,969 undergraduates and offers 109 bachelor's degree programs. There is a student-to-faculty ratio of 18:1 and 81% of classes have fewer than 40 students. Massachusetts hosts Commonwealth Honors College (CHC) where admission is more competitive with an average SAT score of 1411. CHC offers personalized advising, smaller class sizes taught by professors, and a six building Honors Residential Community, which opened in fall 2013.

Students participate in 240 campus organizations, 21 NCAA Division I athletic teams, living-learning residence halls, community service, internships, and faculty research. Massachusetts is also part of the Five Colleges consortium, with Smith, Mount Holyoke, Hampshire, and Amherst colleges, all within a free bus ride of each other using the Pioneer Valley Transit Authority. Students can take classes on any of these campuses and participate in all co-curricular and cultural activities. Javier Reyes serves as UMass Amherst's 12th chancellor.

University of Massachusetts Boston

UMass Boston is a research university located in the City of Boston. Located on the Columbia Point peninsula, the university is surrounded by the Boston Harbor, the John F. Kennedy Library and the Massachusetts State Archives. The Boston Globe is also headquartered adjacent to campus, as well as Boston College High School. Subsequently, the university holds many partnerships with its neighboring organizations, providing research and employment opportunities.

UMass Boston is known for its growing and diverse student body of more than 12,000 undergraduates and nearly 4,000 graduate students, making it the third largest campus in the system. The university has five undergraduate colleges and two graduate colleges, with over 100 undergraduate programs and 50 graduate programs. Ninety-three percent of full-time faculty hold the highest degree in their fields.

The campus is home to more than 100 student organizations—including clubs, literary magazines, newspaper, radio station, art gallery, and 16 NCAA Division III sports teams. Marcelo Suárez-Orozco is the chancellor of the UMass Boston campus.

University of Massachusetts Dartmouth

Located in southeastern Massachusetts, UMass Dartmouth started in 1895 as the New Bedford Textile School, the Bradford Durfee Textile School, and later Southeastern Massachusetts University (SMU). UMass Dartmouth offers a wide array of programs in accounting, finance, management information systems, operations management and marketing, all of which are accredited by the Association to Advance Collegiate Schools of Business (AACSB) International. UMass Dartmouth has top ranking engineering and nursing programs.

In addition to the 710 acre UMass Dartmouth main campus is, satellite campuses are located throughout the SouthCoast.

With 7,982 undergraduate students and 65 degree programs, the campus has a student-to-faculty ratio of 18:1 in its College of Arts & Sciences; Charlton College of Business; College of Engineering; College of Nursing; College of Visual and Performing Arts; School of Education, Public Policy, and Civic Engagement; and the School for Marine Science and Technology. The university hosts internships, undergraduate research opportunities, and service learning experiences, as well as an Honors Program.

More than 100 student organizations and 25 NCAA Division III athletic teams provide a strong community beyond the classroom. The buildings of the campus were designed by internationally renowned Modernist architect Paul Rudolph. Dr. Robert E. Johnson is the chancellor of the UMass Dartmouth campus.

The University of Massachusetts School of Law was opened in September 2010 three miles from the Dartmouth campus.

University of Massachusetts Lowell

UMass Lowell is the product of a 1971 merger between Lowell State College (founded in 1894 as Lowell Normal School) and Lowell Technological Institute (founded in 1895 as the Lowell Textile School). The merged institution became the University of Lowell, with the former Lowell Tech serving as the North Campus and the former Lowell State serving as the South Campus.

UMass Lowell is a comprehensive University with a national reputation in science, engineering, Management and technology, and committed to educating students for lifelong success in a diverse world and conducting research and outreach activities that sustain the economic, environmental and social health of the region.

UMass Lowell is located in the Merrimack Valley, close to Boston, ocean beaches, and the mountains of New Hampshire. With a national reputation for education and research in science, engineering, and technology, the campus offers a number of undergraduate and graduate programs. Academic programs include internships, co-ops, service learning, and international education.

UMass Lowell has a total of 18,316 students as of fall 2017 and is the fastest growing of the five UMass campuses. The campus offers over 120 fully accredited programs taught by 737 faculty members in five colleges. Most of the 75 bachelor's degree programs offer five-year Bachelor's to Master's programs. The student-to-faculty ratio is 15:1 and half of the undergraduate classes have fewer than 20 students. Ninety-three percent of the full-time faculty members hold the highest degree in their fields.

There are 12 University residence halls located on the campus. There are more than 120 active student organizations on campus, a campus recreation center, 16 NCAA Division I sports teams that compete in the America East Conference, and the ice hockey team that competes in the Hockey East Conference.

University of Massachusetts Chan Medical School

The University of Massachusetts Worcester, also known as UMass Chan Medical School or UMass Medical School is one of the fastest growing academic health science centers in the country and is home to the School of Medicine (SOM) — the Commonwealth's only public medical school — the Graduate School of Biomedical Sciences (GSBS), the Graduate School of Nursing (GSN), and a research enterprise that attracts more than $200 million in external funding annually.

Located in the heart of Central Massachusetts on a 63 acre campus it shares with clinical partner UMass Memorial Health Care, the region's premier health care delivery system and largest employer, UMass Chan Medical consistently ranks among the top ten percent in the U.S. News & World Report's annual ranking of best medical schools.

The work of UMass Chan Medical researcher and 2006 Nobel Prize winner Craig Mello, an investigator of the prestigious Howard Hughes Medical Institute, toward the discovery of RNA interference has launched a promising new field of research. The school is also the home of the Albert Sherman Center, an interdisciplinary, research and education facility that fosters collaboration among scientists and innovation across disciplines. Michael F. Collins is the chancellor of the UMass Chan Medical School campus.

University of Massachusetts School of Law
The University of Massachusetts School of Law also known as the University of Massachusetts - Dartmouth Law School, UMass Law School or UMass Law is located near the main campus of UMass Dartmouth in North Dartmouth, Massachusetts and is also a part of UMass Dartmouth.

UMass Law was established in 1981 as the Southeastern Massachusetts-Rhode Island-Avins Law School with a volunteer faculty and a handful of part-time students. It grew from a store-front operation, offering a weekend program of study in Fall River, Massachusetts to a dual-division law school located in its own state-of-the-art facility in North Dartmouth, Massachusetts.

In 1986 the Southeastern Massachusetts-Rhode Island-Avins Law School became the Southern New England School of Law (SNESL). In 1992 the first full-time program at SNESL was established along with SNESL's first day classes. In 1994 SNESL moved to its new current site at 333 Faunce Corner Road in North Dartmouth, Massachusetts. In 1995 SNESL was Accredited by New England Association of Schools and Colleges. In 2009 University of Massachusetts Board of Trustees approves UMass Dartmouth plan to offer Juris Doctor (JD) degrees at SNESL.

In 2010 the Massachusetts Board of Higher Education authorized UMass Dartmouth to offer JD degrees along with the establishment of the University of Massachusetts School of Law - Dartmouth (UMass Law). UMass Law was made possible by a $23 million donation of assets, a facility, land, library, technology, and cash from the Southern New England School of Law. In 2010 at the time of the donation from SNESL, SNESL had 1,200 alumni, 200 students, 13 full-time faculty members, and 24 adjunct faculty.

Also in 2010 the first UMass Law class matriculates. In 2011 UMass Law confers their first JD degrees. In 2012 UMass Law was granted provisional approval by Council of the Section of Legal Education and Admissions to the Bar of the American Bar Association. In 2013 UMass Law was ranked among the top five law schools in region for black students in the Lawyers of Color Black Student's Guide to Law Schools 2014. In 2014 UMass Law was named to The National Jurist's first honor roll of law schools that deliver practical training along with the Justice Bridge Legal Access Center at UMass Law was commenced. In 2016 UMass Law was granted full approval by Council of the Section of Legal Education and Admissions to the Bar of the American Bar Association.

Springfield satellite center

 * UMass Amherst Center at Springfield

On August 8, 2013, The University of Massachusetts started requesting proposals for potential classroom and office space to establish a satellite center in Springfield. UMass was looking for 25,000 square feet of space that it would use for classrooms, faculty offices and other uses, with the option of doubling the amount of space at a later date. On November 23, 2013, Gov. Deval Patrick and University of Massachusetts President Robert L. Caret announced the selection of Tower Square in downtown Springfield as the university's new satellite center. The university would lease 27,321 square feet on the second floor of the 30-floor building, which is owned by the Massachusetts Mutual Life Insurance Co. and located at 1500 Main St. UMass planned to establish academic programs at the center starting in the fall 2014.

In 2014, the state of Massachusetts gave $5.2 million to the Springfield satellite center to allow the university to complete construction and buy furnishings. .

The satellite center, administered by the Amherst campus, opened in March 2014, registering students for September 2014. Programs include nursing, education, business administration, addiction counseling, and GED classes. Enrollment in the more than 20 courses offered at the center has grown from 250 students in the fall of 2014 when it opened to 850 in the spring of 2016, according to Daniel Montagna, director of operations at the center. From courses leading to bachelor and doctoral degrees in nursing to a master's degree in business administration, and from a 180-day teacher certification program to a cybersecurity certificate program fueled by a $5 million investment by MassMutual.

University of Massachusetts Global
In September 2021, Brandman University reaffiliated with the University of Massachusetts from Chapman University via a change of control agreement and rebranded as UMass Global.

Collaborations
The Massachusetts Green High Performance Computing Center is a joint venture of the University of Massachusetts system, MIT, Harvard, Boston University, and Northeastern to build a shared high-performance computing facility. In 2010, UMass Boston partnered with Dana–Farber/Harvard Cancer Center to collaborate on research aimed at addressing issues of cancer health disparities in disenfranchised populations under U54 Cancer Partnership.

Inter Campus Programs
University of Massachusetts Intercampus Graduate School of Marine Sciences and Technology is a graduate degree program offering Master of Science, Doctor of Philosophy and Professional Science Master's Degree. The graduates receive a joint degree from all four of the main UMass campuses.

Finances and faculty pay
The FY 2014 Operating Budget for the UMass system is $2.94 billion representing a 2.6% increase over the current year expenses. Several University of Massachusetts employees are among the highest paid state employees in Massachusetts.

University president
The president is the university's chief executive officer and works to advance its mission of education, research and public service. Marty Meehan became the 27th president of the five-campus, 73,000-student University of Massachusetts system on July 1, 2015.

Before the 1962 establishment of the medical school, the president was the administrator of the system's only campus in Amherst. When UMass Boston was organized in 1964, it was headed by a chancellor who reported to the president. In 1970, as part of a reorganization, day-to-day leadership responsibilities for UMass Amherst were transferred to a chancellor, with both chancellors reporting on an equal basis to the president. Today, the president administers five campuses.

Board of trustees
The University of Massachusetts is governed by a lay board of trustees. The board of trustees functions as a legislative body dealing mainly with questions of policy. The board is not an administrative or management board. In certain rare instances when required by the Massachusetts General Laws, it may function as an appeal body. The board establishes the general policies governing the university, but has delegated many powers to the president and, through the president, to campus administrators for day-to-day-operations.

The founding board had fourteen appointed members and four ex-officio members. Formerly, trustees were appointed by the legislature or the board itself; currently, members are appointed by the governor. The size of the board has fluctuated between twelve and twenty-four members. The current board is composed of nineteen voting members and three ex-officio non-voting members. Seventeen board members are appointed by the governor of the Commonwealth; at least five of those appointed must be alumni of the university, and one must be a representative of organized labor. The other two voting members are students. Overall, the board has five student members, elected for one-year terms, from the Amherst, Boston, Dartmouth, Lowell and Worcester campuses. Voting membership rotates among the campuses: two students are voting members and three others are ex officio non-voting members.

Honorary alumni
The University of Massachusetts awarded its first-ever system-wide honorary degrees in 2006.

Hartsfield–Jackson Atlanta International Airport

Hartsfield–Jackson Atlanta International Airport is the primary international airport serving Atlanta and its surrounding metropolitan area, in the U.S. state of Georgia. The airport is located 10 mi south of the Downtown Atlanta district. It is named after former Atlanta mayors William B. Hartsfield and Maynard Jackson. The airport covers 4,700 acre of land and has five parallel runways which are aligned in an east-west direction. There are three runways that are 9,000 feet long, one runway that is 10,000 feet long, and the longest runway at ATL measures 12,390 feet long, which can handle the Airbus A380. Since 1998, Hartsfield-Jackson has been the world's busiest airport by passenger traffic. In 2023, the airport served over 104.6 million passengers, the most of any airport in the world. Hartsfield–Jackson is the corporate headquarters and primary hub of Delta Air Lines. With just over 1,000 flights a day to 225 domestic and international destinations, the Delta hub is the world's largest airline hub and is considered the first mega-hub in America. Additionally, Hartsfield–Jackson is also the home of Delta's Technical Operations Center, which is the airline's primary maintenance, repair and overhaul arm. Aside from Delta, Hartsfield-Jackson is also a focus city for low-cost carriers Frontier Airlines and Southwest Airlines. The airport has international service within North America and to Latin America, Europe, Africa, Middle East and East Asia.

The airport is mostly in unincorporated areas of Clayton County, but it spills into the city limits of Atlanta, College Park, and Hapeville, in territory extending into Fulton County. The airport's domestic terminal is served by MARTA's Red and Gold rail lines.

Candler Field/Atlanta Municipal Airport (1925–1961)
Hartsfield–Jackson began with a five-year, rent-free lease on 287 acre that was an abandoned auto racetrack named The Atlanta Speedway. The lease was signed on April 16, 1925, by Mayor Walter Sims, who committed the city to develop it into an airfield. As part of the agreement, the property was renamed Candler Field after its former owner, Coca-Cola tycoon and former Atlanta mayor Asa Candler. The first flight into Candler Field was September 15, 1926, a Florida Airways mail plane flying from Jacksonville, Florida. In May 1928, Pitcairn Aviation began service to Atlanta, followed in June 1930 by Delta Air Service. Those two airlines, later known as Eastern Air Lines and Delta Air Lines, respectively, would both use Atlanta as their chief hubs. The airport's weather station became the official location for Atlanta's weather observations on September 1, 1928, and records by the National Weather Service.

Atlanta was a busy airport from its inception, and by the end of 1930, it was third behind New York City and Chicago for regular daily flights with sixteen arriving and departing. Candler Field's first control tower opened March 1939. The March 1939 Official Aviation Guide shows fourteen weekday airline departures: ten Eastern and four Delta.

In October 1940, the U.S. government declared it a military airfield and the United States Army Air Forces operated Atlanta Army Airfield jointly with Candler Field. The Air Force used the airport primarily to service many types of transient combat aircraft. During World War II, the airport doubled in size and set a record of 1,700 takeoffs and landings in a single day, making it the nation's busiest in terms of flight operation. Atlanta Army Airfield closed after the war.

In 1942, Candler Field was renamed Atlanta Municipal Airport and by 1948, more than one million passengers passed through a war surplus hangar that served as a terminal building. Delta and Eastern had extensive networks from ATL, though Atlanta had no nonstop flights beyond Texas, St. Louis, and Chicago until 1961. Southern Airways appeared at ATL after the war and had short-haul routes around the Southeast until 1979.

In 1957, Atlanta saw its first jet airliner: a prototype Sud Aviation Caravelle that was touring the country arrived from Washington, D.C. The first scheduled turbine airliners were Capital Viscounts in June 1956; the first scheduled jets were Delta DC-8s in September 1959. The first trans-Atlantic flight was a Delta/Pan Am interchange DC-8 to Europe via Washington starting in 1964; the first scheduled international nonstops were Eastern flights to Mexico City and Jamaica in 1971–72. Nonstops to Europe started in 1978 and to Asia in 1992–93.

Atlanta claimed to be the country's busiest airport, with more than two million passengers passing through in 1957 and, between noon and 2p.m. each day, it became the world's busiest airport. (The April 1957 OAG shows 165 weekday departures from Atlanta, including 45 between 12:05 and 2:00 PM and 20 between 2:25 and 4:25 AM.) Chicago Midway had 414-weekday departures, including 48 between 12:00 and 2:00 PM. In 1957, Atlanta was the country's ninth-busiest airline airport by flight count and about the same by passenger count.

Original Jet Terminal (1961–1980)
In late 1957, work began on a new $21 million terminal, which opened on May 3, 1961. Consisting of six pier concourses radiating from a central building, the terminal was the largest in the country and could handle over six million travelers a year; the first year, nine and a half million people passed through. In March 1962, the longest runway (9/27, now 8R) was 7860 ft; runway3 was 5505 ft and runway 15 was 7220 ft long.

In 1971, the airport was named William B. Hartsfield Atlanta Airport in honor of Atlanta mayor William B. Hartsfield after his death. The name change took effect on February 28, which would have been Hartsfield's 81st birthday. The new name would be relatively brief, as it would be changed later in 1971 to William B. Hartsfield Atlanta International Airport with the growth of flights to and from Atlanta outside North America.

Midfield Terminal (1980–present)
To address the significant increase in air traffic that outstripped the capacity of the 1961 terminal, and after years of planning and design, construction began on the present midfield terminal complex in January 1977 under the administration of Mayor Maynard Jackson. It was billed as the largest construction project in the South, costing $500 million. The complex was designed by Stevens & Wilkinson, Smith Hinchman & Grylls, and Minority Airport Architects & Planners. The new complex, initially consisting of the North and South Terminals, Concourses A through D, and the northern half of the present-day Concourse T (which served as the International Terminal), opened on September 21, 1980, on time and under budget. It was designed to accommodate up to 55 million passengers per year and covered 2.5 million square feet (230,000 m2). In December 1984, a 9000 ft fourth parallel runway was completed, and another runway was extended to 11889 ft the following year. To accommodate increases in international air traffic, a southern extension of Concourse T opened in March 1987, and Concourse E opened in September 1994 in advance of Atlanta hosting the 1996 Summer Olympics, with Concourse T subsequently being converted to use by domestic flights. MARTA rail service was extended to Hartsfield with the opening of the Airport station in June 1988 (the station itself was constructed in 1979-80 as part of the airport complex).

In 1999, Hartsfield–Jackson's leadership established the Development Program: "Focus On the Future," involving multiple construction projects to prepare the airport to handle a projected demand of 121 million passengers in 2015. The program was originally budgeted at $5.4 billion over ten years, but the total was revised as of 2007 to over $9 billion.

In May 2001, construction of an over 9000 ft fifth runway (10–28) began. It was completed at the cost of $1.28 billion and opened on May 27, 2006. It bridges Interstate 285 (the Perimeter) on the airport's south side, making Hartsfield–Jackson the nation's only currently active civil airport to have a runway above an interstate (although Runway 17R/35L at Stapleton International Airport in Denver, Colorado, crossed Interstate 70 until that airport closed in 1995). The massive project, which involved putting fill dirt eleven stories high in some places, destroyed some surrounding neighborhoods and dramatically changed the scenery of Flat Rock Cemetery and Hart Cemetery, both on the airport property. It was added to help ease traffic problems caused by landing small- and mid-size aircraft on the runways used by larger planes such as the Boeing 777, which need longer runways than the smaller planes. With the fifth runway, Hartsfield–Jackson is one of only a few airports that can perform triple simultaneous landings. The fifth runway was expected to increase the capacity for landings and take-offs by 40%, from an average of 184 flights per hour to 237 flights per hour.

Along with the fifth runway, a new control tower was built to see the entire runway length. The new control tower is the tallest in the United States, over 398 ft tall. The old control tower, at 231 ft, was demolished in August 2006.

On October 20, 2003, the Atlanta City Council voted to rename Hartsfield–Jackson Atlanta International Airport to honor former mayor Maynard Jackson, who died June 23, 2003. The council planned to drop Hartsfield's name from the airport, but public outcry (occurring coincidentally during a debate over the state's flag) prevented this.

In April 2007, an "end-around taxiway" opened, Taxiway Victor. It is expected to save an estimated $26 million to $30 million in fuel each year by allowing airplanes landing on the northernmost runway to taxi to the gate area without preventing other aircraft from taking off. The taxiway drops about 30 ft from runway elevation to allow takeoffs to continue.

After the Southeastern U.S. drought of 2007, the airport (the state's eighth-largest water user) changed to reduce water usage. This included adjusting toilets (725 commodes and 338 urinals) and 601 sinks. (The two terminals alone use 917,000 gal a day.) It also stopped using firetrucks to spray water over aircraft when the pilot made the last landing before retirement (a water salute). The city of Macon offered to sell water to the airport through a proposed pipeline.

The airport today employs about 55,300 airline, ground transportation, concessionaire, security, the federal government, the City of Atlanta, and airport tenant employees and is the largest employment center in Georgia. With a payroll of $2.4 billion, the airport has a direct and indirect economic impact of $3.2 billion on the local and regional economy and an annual regional economic impact of more than $19.8 billion.

In December 2015, the airport became the first airport in the world to serve 100 million passengers in a year. The airport is routinely cited as one of the world's busiest, topping the Airports Council International rankings in 2022 and 2023.

Historical airline service
Delta and Eastern dominated the airport during the 1970s. United, Southern, Piedmont, Northwest and TWA were also present. In 1978, after airline deregulation, United no longer served Atlanta, while Southern successor Republic was the airport's third-largest carrier.

Eastern was a larger airline than Delta until deregulation in 1978, but Delta was early to adopt the hub-and-spoke route system, with Atlanta as a hub between the Midwest and Florida, giving it an advantage in the Atlanta market. Eastern ceased operations in 1991 because of labor issues; American Airlines considered establishing an Atlanta hub around that time but decided Delta was too strong there and instead replaced Eastern's other hub in Miami. TWA created a small hub at Atlanta in 1992 but abandoned the concept in 1994 leaving Delta with a monopoly hub at Atlanta.

From the 1980s until Eastern's demise in 1991, Delta occupied ConcourseA and part of ConcourseB, Eastern occupied the remainder of ConcourseB and ConcourseC, other domestic airlines used ConcourseD, and ConcourseT was used by international flights. By the mid-1990s, Delta's hub grew to occupy all of ConcourseB and the southern half of ConcourseT, and international flights moved to the new ConcourseE.

Japan Airlines was the first Asian carrier to serve Atlanta in 1986. In December 1994, Korean Air became the second Asian carrier to serve the airport.

ValuJet was established in 1993 as low-cost competition for Delta at ATL. However, its safety practices were questioned early, and the airline was grounded after the 1996 crash of ValuJet Flight 592. It resumed operations in 1997 as AirTran Airways and was the second-largest airline at ATL until it was acquired by Southwest in 2011 and absorbed into Southwest on December 28, 2014. Southwest is now the airport's second-largest carrier.

In recent years the airport has had an increase in non-Delta flights, both due to the rapid population growth of Metro Atlanta and the airport's prominence as a major hub.

Since 2015 the airport has seen growth from low cost carriers such as Frontier Airlines and Spirit Airlines. Spirit also established Atlanta as an operating base.

In addition to the growth of the low cost carriers, international carriers have increasingly offered service to Atlanta since 2014. On May 21, 2014, Virgin Atlantic began offering direct flights to London and on October 26, 2015, the airline began offering direct flights to Manchester. On May 16, Turkish Airlines began offering direct flights to Istanbul and Qatar Airways began Doha flights on June 1. On March 3, 2019, WestJet began offering direct flights to Calgary, and in May 2023, the airline started non-stop service to Vancouver and also started Winnipeg service on September 6. On April 29, 2024, WestJet began non-stop service to Edmonton. Copa Airlines became the first Latin American carrier to serve the airport in December 2021 with direct flights to Panama City. On June 1, 2022, Air Canada reintroduced Montreal service. Ethiopian Airlines started service to Atlanta on May 17, 2023, becoming the first African carrier to serve the airport since South African Airways ended service in 2006. LATAM Perú started service to Atlanta on October 29, 2023 from Lima. Aeromexico Connect resumed service to Atlanta on January 8, 2024 with nonstop service to Guadalajara and Monterrey. Nonstop service to Leon/Guanajuato and Mérida began in mid-March. Nonstop service to Querétaro will begin in August. Scandinavian Airlines started service to Atlanta on June 17 with direct flights from Copenhagen.

Terminals
Hartsfield–Jackson Atlanta International Airport has two terminals and seven concourses with a total of 192 gates. The Domestic Terminal is located on the west side of the airport and the Maynard H. Jackson Jr. International Terminal is on the east side of the airport. The terminals and concourses are connected by the Transportation Mall, a pedestrian tunnel with a series of moving walkways and The Plane Train, a 24/7 underground automated people mover. All international arrivals are processed in Concourses E and F; Concourse F is the only concourse in the airport that has a gate that can support an Airbus A380, the largest passenger aircraft in the world. All non-Delta international carriers operate their ATL flights from this terminal, including Delta's partners such as Air France, KLM, Korean Air, Virgin Atlantic, and WestJet. Aeromexico operates in the Concourse E terminal.
 * Concourse T contains 21 gates.
 * Concourse A contains 29 gates.
 * Concourse B contains 32 gates.
 * Concourse C contains 34 gates.
 * Concourse D contains 40 gates.
 * Concourse E contains 28 gates.
 * Concourse F contains 12 gates.

Ground transportation
The domestic terminal can be accessed directly from Interstate 85 SB at exit 72/Camp Creek Pkwy, or from Interstate 85 NB at exit 71/Riverdale Rd. The international terminal is accessed directly from Interstate 75 SB or NB at exit 239. These freeways in turn connect with the following additional freeways within 10 miles: Interstate 285, Interstate 675, Georgia State Route 166, Interstate 20.

Hartsfield–Jackson has its own train station on the city's rapid transit system, MARTA, served by the Red and Gold lines. The above-ground station is inside the main building, between the north and south domestic terminals on the west end. The Airport station is currently the southernmost station in the MARTA system, though expansions via metro or commuter rail further south into Clayton County have been discussed.

Several local shared-ride shuttle services are readily available at Atlanta Airport, offering diverse options for travelers seeking convenient transportation.

The Hartsfield–Jackson Rental Car Center, which opened December 8, 2009, houses all ten airport rental agencies with capacity for additional companies. The complex features 9,900 parking spaces split between two four-story parking decks that together cover 2.8 e6sqft, a 137000 sqft customer service center, and a maintenance center featuring 140 gas pumps and 30 wash bays equipped with a water recovery system. An automated people mover, the ATL SkyTrain, runs between the rental car center, the Domestic Terminal, and the Gateway Center of the Georgia International Convention Center, while a four-lane roadway that spans Interstate 85 connects the rental car center with the existing airport road network.

Other facilities
The 990 Toffie Terrace hangar, a part of Hartsfield–Jackson Airport and located within the City of College Park corporate limits, is owned by the City of Atlanta. The building now houses the Atlanta Police Department Helicopter Unit. It once served as the headquarters of the regional airline ExpressJet.

Before its merger with ExpressJet, Atlantic Southeast Airlines was headquartered in the hangar, then named the A-Tech Center. In December 2007, the airline announced it was moving its headquarters into the facility, previously named the "North Hangar." The 203000 sqft hangar includes 100000 sqft of hangar bays for aircraft maintenance. It has 17 acre of adjacent land and 1,400 parking spaces for employees. The airline planned to relocate 100 employees from Macon to the new headquarters. The Atlanta City Council and Mayor of Atlanta Shirley Franklin approved the new 25-year ASA lease, which also gave the airline new hangar space to work on 15 to 25 aircraft in overnight maintenance; previously, its aircraft were serviced at ConcourseC. The airport property division stated that the hangar was built in the 1960s and renovated in the 1970s. Eastern Air Lines and Delta Air Lines had previously occupied the hangar. Delta's lease originally was scheduled to expire in 2010, but the airline returned the lease to the City of Atlanta in 2005 as part of its bankruptcy settlement. The city collected an insurance settlement of almost $900,000 due to the cancellation.

Passenger
The flight from Atlanta to Addis Ababa is nonstop.

Accidents and incidents

 * On May 23, 1960, Delta Air Lines Flight 1903, a Convair CV-880-22-1 (N8804E), crashed on takeoff resulting in the loss of all four crew members. This flight was a training flight for two Delta captains who were being type-rated on the 880.
 * On February 25, 1969, Eastern Air Lines Flight 955 was hijacked by one passenger shortly after takeoff from ATL en route to Miami. The man pulled a .22 caliber pistol and demanded to be flown to Cuba. He got off the plane in Cuba while the DC-8 was allowed to fly back to the U.S.
 * On April 4, 1977, Southern Airways Flight 242 was on descent to the airport when hail was ingested into the engines, leading them to fail. Pilot errors and difficult weather forced the pilots to attempt an emergency landing on a highway. Upon touchdown, the aircraft struck several buildings and cars, killing 72 people.
 * On January 18, 1990, Eastern Air Lines Flight 111, a Boeing 727, overran a Beechcraft King Air operated by Epps Air Service, based at another Atlanta airport. The King Air had landed and was taxiing when the 727, still at high speed in its landing roll, collided with the aircraft. The larger plane's wing impacted the roof of the smaller. The pilot of the King Air, an Epps charter pilot, was killed, while a passenger survived. No crew or passengers on the Eastern plane were injured.
 * On November 1, 1998, AirTran Airways Flight 867, a Boeing 737, lost control and skidded off of the runway while landing, with main landing gear in a drainage ditch and its empennage extending over the taxiway. The nose gear was folded back into the electrical/electronic compartment and turned 90 degrees from its normal, extended position. The cause was an improperly repaired hydraulic line leak that caused the flight crew to lose control of the airplane.

O'Hare International Airport

Chicago O'Hare International Airport is a major international airport serving Chicago, Illinois, United States, located on the city's Northwest Side, approximately 17 mi northwest of the Loop business district. Operated by the Chicago Department of Aviation and covering 7627 acres, O'Hare has non-stop flights to 249 destinations in North America, South America, the Caribbean, Europe, Africa, Asia, the Middle East, Oceania, and the North Atlantic region as of Summer 2024. As of 2023, O'Hare is considered the world's most connected airport. It is also the United States' 4th busiest airport, and 7th biggest airport.

Designed to be the successor to Chicago's Midway International Airport, itself once nicknamed the "busiest square mile in the world," O'Hare began as an airfield serving a Douglas manufacturing plant for C-54 military transports during World War II. It was renamed Orchard Field Airport in the mid-1940s and assigned the IATA code ORD. In 1949, it was renamed after aviator Edward "Butch" O'Hare, the U.S. Navy's first Medal of Honor recipient during that war. As the first major airport planned after World War II, O'Hare's innovative design pioneered concepts such as concourses, direct highway access to the terminal, jet bridges, and underground refueling systems.

O'Hare became famous during the jet age, holding the distinction as the world's busiest airport by passenger traffic from 1963 to 1998. It still ranks as one the busiest airports in the world, according to the Airports Council International rankings. In 2019, O'Hare had 919,704 aircraft movements, averaging 2,520 per day, the most of any airport in the world in part because of a large number of regional flights. On the ground, road access to the airport is offered by airport shuttle, bus, the Chicago "L", or taxis. Interstate 190 (Kennedy Expressway) goes directly into the airport. O'Hare is a hub for American Airlines and United Airlines (which is headquartered in Willis Tower), as well as an operating base for Spirit Airlines.

Establishment and defense efforts
Soon after the opening of Chicago Municipal Airport in 1926, the City of Chicago realized more airport capacity would be needed. The city government investigated various sites in the 1930s but made little progress before America's entry into World War II.

O'Hare began as a manufacturing plant for Douglas C-54 Skymasters during World War II. The site was known as Orchard Place, previously a small German-American farming community. The 2 e6sqft plant, in the northeast corner of what is now the airport, needed easy access to the workforce of the nation's second-largest city, as well as its railroads and location far from enemy threat. 655 C-54s were built at the plant, more than half of all produced. The airfield, from which the C-54s flew out, was known as Douglas Airport; initially, it had four 5500 ft runways. Less known is the fact that it was the location of the Army Air Force's 803rd Specialized Depot, a unit charged with storing many captured enemy aircraft; a few representatives of this collection would eventually be transferred to the Smithsonian Institution's National Air and Space Museum.

Douglas Company's contract ended with the war's conclusion. Douglas considered building airliners at Orchard but chose to concentrate civil production at its headquarters in Santa Monica, California. With the departure of Douglas, the complex took the name Orchard Field Airport, and was assigned the IATA code ORD.

The United States Air Force used the field extensively during the Korean War; the airport then had no scheduled airline service. Although not its primary base in the area, the Air Force used O'Hare as a fighter base; it was home to the 62nd Fighter-Interceptor Squadron flying North American F-86 Sabres from 1950 to 1959. By 1960, the need for O'Hare as an active duty fighter base was diminishing, just as commercial business was picking up at the airport. The Air Force removed active-duty units from O'Hare and turned the station over to Continental Air Command, enabling them to base reserve and Air National Guard units there. As a result of a 1993 agreement between the City and the Department of Defense, the reserve base was closed on April 1, 1997, ending its career as the home of the 928th Airlift Wing and of the 126th Air Refueling Wing in 1999. At that time, the remaining 357 acre site came under the ownership of the Chicago Department of Aviation.

Early commercial development
In 1945, Chicago mayor Edward Kelly established a board to choose the site of a new airport to meet future demand. After considering various proposals, the board decided upon the Orchard Field site and acquired most of the federal government property in March 1946. The military retained a small parcel of property on the site and the right to use 25% of the airfield's operating capacity for free.

Ralph H. Burke devised an airport master plan based on the pioneering idea of what he called "split finger terminals", allowing a terminal building to be attached to "airline wings" (concourses), each providing space for gates and planes. (Pre-war airport designs had favored ever-larger single terminals, exemplified by Berlin's Tempelhof.) Burke's design also included underground refueling, direct highway access to the front of terminals, and direct rail access from downtown, all of which are utilized at airports worldwide today. O'Hare was the site of the world's first jet bridge in 1958, and successfully adapted slip form paving, developed for the nation's new Interstate highway system, for seamless concrete runways.

In 1949, the City renamed the facility O'Hare Airport to honor Edward "Butch" O'Hare, the U.S. Navy's first flying ace and Medal of Honor recipient in World War II. Its IATA code (ORD) remained unchanged, however, resulting in O'Hare being one of the few IATA codes bearing no connection to the airport's name or metropolitan area.

Arrival of passenger service and subsequent growth
Scheduled passenger service began in 1955, but growth was slow at first. Although Chicago had invested over $25 million in O'Hare, Midway remained the world's busiest airport and airlines were reluctant to move until highway access and other improvements were completed. The April 1957 Official Airline Guide listed 36 weekday departures from O'Hare, while Midway had 414. Improvements began to attract the airlines: O'Hare's first international terminal opened in August 1958, and by April 1959 the airport had expanded to 7,200 acre with new hangars, terminals, parking and other facilities. The expressway link to downtown Chicago, now known as the Kennedy Expressway, was completed in 1960. And new Terminals2 and3, designed by C. F. Murphy and Associates, opened on January 1, 1962.

The biggest factor driving airlines to relocate their operations from Midway to O'Hare was the jet airliner; the first scheduled jet at O'Hare was an American 707 from New York to Chicago to San Francisco on March 22, 1959. One-mile-square (2.6-kilometer-square) Midway had no space for the runways that 707s and DC-8s required. Airlines had been reluctant to move to O'Hare, but they naturally did not want to split their operations: in July 1962, the last fixed-wing scheduled airline flight in Chicago moved from Midway to O'Hare. Until United returned in July 1964, Midway's only scheduled airline was Chicago Helicopter Airways. The arrival of Midway's traffic quickly made O'Hare the world's busiest airport, serving 10 million passengers annually. Within two years, that number would double, with Chicagoans boasting that more people passed through O'Hare in 12 months than Ellis Island had processed in its entire existence. O'Hare remained the world's busiest airport until it was eclipsed by Hartsfield-Jackson Atlanta International Airport in 1998.

O'Hare had four runways in 1955; 8000 foot runway 14R/32L opened in 1956 and was extended to 11600 ft a few years later, allowing nonstops to Europe. Runway 9R/27L (now 10L/28R) opened in 1968 and runway 4R/22L in 1971.

Post-deregulation developments
In the 1980s, after passage of US airline deregulation, the first major change at O'Hare occurred when TWA left Chicago for St. Louis as its main mid-continent hub. Although TWA had a large hangar complex at O'Hare and had started Constellation nonstops to Paris in 1958, by the time of deregulation its operation was losing $25 million a year under competition from United and American. Northwest likewise ceded O'Hare to the competition and shifted to a Minneapolis/St. Paul and Detroit-centered network by the early 1990s after acquiring Republic Airlines in 1986. Delta maintained an O'Hare hub for some time, even commissioning a new ConcourseL in 1983. Ultimately, Delta found competing from an inferior position at O'Hare too expensive and closed its Chicago hub in the 1990s, concentrating its upper Midwest operations at Cincinnati.

The dominant hubs established at O'Hare in the 1980s by United and American continue to operate today. United developed a new two-concourse Terminal1 (dubbed "The Terminal for Tomorrow"), designed by Helmut Jahn. It was built between 1985 and 1987 on the site of the original Terminal1; the structure, which includes 50 gates, is best known for its curved glass forms and the connecting underground tunnel between ConcoursesB andC. The tunnel is illuminated with a neon installation titled Sky's the Limit (1987) by Canadian artist Michael Hayden, which plays an airy, slow-tempo version of Rhapsody in Blue. American renovated and expanded its existing facilities in Terminal3 from 1987 to 1990; those renovations feature a flag-lined entrance hall to ConcoursesH/K.

The demolition of the original Terminal 1 in 1984 to make way for Jahn's design forced a "temporary" relocation of international flights into facilities called "Terminal4" on the ground floor of the airport's central parking garage. International passengers were then transferred by bus to and from their aircraft. Relocation finally ended with the completion of the 21-gate International Terminal in 1993 (now called Terminal5); it contains all customs facilities. Its location, on the site of the original cargo area and east of the terminal core, necessitated the construction of a peoplemover, which connected the terminal core with the new terminal as well as remote rental and parking lots.

Following deregulation and the buildup of the American and United hubs, O'Hare faced increasing delays from the late 1980s onward due to its inefficient runway layout; the airfield had remained unchanged since the addition of its last new runway (4R/22L) in 1971. O'Hare's three pairs of angled runways were meant to allow takeoffs into the wind, but they came at a cost: the various intersecting runways were both dangerous and inefficient. Official reports at the end of the 1990s ranked O'Hare as one of the worst-performing airports in the United States based on the percentage of delayed flights. In 2001, the Chicago Department of Aviation committed to an O'Hare Modernization Plan (OMP). Initially estimated at $6.6 billion, the OMP was to be paid by bonds issued against the increase in the federal passenger facility charge enacted that year and federal airport improvement funds. The modernization plan was approved by the FAA in October 2005 and involved a complete reconfiguration of the airfield. The OMP included the construction of four new runways, lengthening two existing runways, and decommissioning three old runways to provide O'Hare with six parallel runways and two crosswind runways.

The OMP was the subject of legal battles, both with suburbs who feared the new layout's noise implications as well as with survivors of persons interred in a cemetery the city proposed to relocate; some of the cases were not resolved until 2011. These issues, plus the reduction in traffic as a result of the 2008 financial crisis, delayed the OMP's completion; construction of the sixth and final parallel runway (9C/27C) began in 2016. Its completion in 2020, along with an extension of runway 9R/27L completed in 2021, concluded the OMP.

Expansion
In 2018, the city and airlines committed to PhaseI of a new Terminal Area Plan dubbed O'Hare 21. The plan was to build two all-new satellite concourses to the southwest of Concourse C, and to expand Terminals 2 and 5 with additional gates, lounges, and updates to operations all over the airport. (Terminal 5 has ten new gates in addition to its newly expanded facilities, plus two additional gates to each accommodate an Airbus A380.) The expansion will enable same-terminal transfers between international and domestic flights, faster connections, improved facilities and technology for TSA and customs inspections and much larger landside amenities such as shopping and restaurants. A principal feature of the plan is the reorganization of the terminal core into an "alliance hub," the first in North America; airside connections and layout will be optimized around airline alliances. This will be made possible by the construction of the O'Hare Global Terminal (OGT) where Terminal2 currently stands. The OGT and two new satellite concourses will allow for expansion for both American's and United's international operations as well as easy interchange with their respective Oneworld (American) and Star Alliance (United) partner carriers, eliminating the need to transfer to Terminal 5.

This project will add over 3 e6sqft to the airport's terminals, add a new customs processing center in the OGT, reconstruct gates and concourses (new concourses will be a minimum of 150 ft wide), increase the gate count from 185 to 235, and provide 25% more ramp space at every gate throughout the airport to accommodate larger aircraft. After an international design competition that featured public voting on five final architectural proposals, the Studio ORD group, led by architect Jeanne Gang (in collaboration with SCB, Corgan, Milhouse, and STL Architect), was selected to design the OGT, while Skidmore, Owings & Merrill LLP will design Satellites1 and2. By terms of the agreement, total costs of $8.5 billion for the project are to be borne by bonds issued by the city, which will be retired by airport usage fees paid by the airlines. O'Hare 21 is scheduled for completion of the two satellite terminals in 2028, and overall completion in 2030.

In November 2023, the project's cost had ballooned far over budget, leading both American Airlines and United Airlines to call for the global terminal project to be cancelled or scaled back. Later, in May 2024, American Airlines and United Airlines were able to reach an agreement with the City of Chicago to allow the project to continue. In the agreement, the replacement of Terminal 2 would be accelerated, while the addition of the two satellite concourses would be delayed. The replacement of Terminal 2 with the OGT was deemed more critical to complete first instead of the satellite concourses.

Terminals
O'Hare has four numbered passenger terminals with nine lettered concourses and a total of 213 gates- the most of any airport in the world.

 * Terminal 1 is used for United Airlines, Lufthansa and All Nippon Airways flights. It contains 52 gates on two concourses, lettered B–C.
 * Terminal 2 is used for most United Express and some mainline United flights, as well as all Air Canada, Alaska Airlines, and JetBlue flights. It contains 41 gates on two concourses, lettered E–F.
 * Terminal 3 is used for American Airlines, Aer Lingus, British Airways, Iberia, Japan Airlines, and Spirit Airlines flights. It contains 80 gates on four concourses, lettered G, H, K, and L.
 * Terminal 5 is used for Delta Air Lines, Frontier Airlines and Southwest Airlines flights, as well as all international airlines save for those that depart from Terminals 1–3. Terminal 5 is also used for non-pre–cleared international arrivals, as it currently contains the airport's U.S. Customs and Border Protection facilities. It contains 35 non-sequential gates on a single concourse with the highest number being 40, lettered M. (Note that Terminal 5 is very long, so be prepared for a 20 minute walk.)

Terminals 1–3 are interconnected airside via a walkway. Terminal 5 is separated from the other terminals by a set of taxiways that cross over the airport's access road, requiring most passengers to exit security, ride a shuttle bus or take the Airport Transit System and then re–clear security. An additional shuttle bus provides an airside connection from Terminals 1 and 3 to Terminal 5, operating every 15 minutes from 11:30 am to 9:30 pm.

Runways
O'Hare has two sets of parallel runways, one on either side of the terminal complex. Each airfield has three parallel east–west runways (9L/27R, 9C/27C, and 9R/27L on the north side; 10L/28R, 10C/28C, and 10R/28L on the south side) and a crosswind runway oriented northeast–southwest (4L/22R on the north, 4R/22L on the south). The north crosswind runway, 4L/22R, sees limited usage due to intersecting 9R/27L and 9C/27C; however, runway 22L is often used for takeoffs during what is called "west flow" on the main runways. The airfield is managed by three FAA air traffic control towers. O'Hare has a voluntary nighttime (22:00–07:00) noise abatement program.

In 2015, runway 32R/14L was permanently closed after 72 years of service, in favor of the new runway 10R/28L.

Currently, O'Hare has the most runways of any civilian airport in the world, totaling eight.

Hotel
The Hilton Chicago O'Hare is between the terminal core and parking garage and is currently the only hotel on airport property. It is owned by the Chicago Department of Aviation and operated under an agreement with Hilton Hotels, who extended their agreement with the city by ten years in 2018.

Ground transportation
The Airport Transit System shuttles passengers between the terminal core (Terminals 1–3), Terminal 5, and the O'Hare Multi-Modal Facility (MMF). The system, which re-opened on November 3, 2021, resumed round-the-clock service starting at 5 a.m. on Monday, April 18, 2022, after a nearly six-year renovation. Meanwhile, free shuttle buses also continue to run 24/7 and contribute to congestion, boarding on the upper (departures) level of all terminals. The Bus Shuttle center, located on the ground level of the parking garage between Terminals 1–3 and directly opposite the Hilton Hotel, provides a temporary boarding location for local hotel shuttles and regional public transport buses. The O'Hare Multi-Modal Facility is the home of all on-airport car rental firms as well as some extended parking. In addition, the Chicago-area commuter rail system, Metra, has a transfer station of its North Central Service (NCS) located at the northeast corner of the MMF; however, the NCS currently operates an occasional schedule on weekdays only.

The CTA Blue Line's north terminus is at O'Hare and provides direct service to downtown via the Milwaukee–Dearborn subway in the Loop and continuing to west suburban Forest Park. Trains depart at intervals ranging from every four to thirty minutes, 24 hours a day. The station is located on the lower level of the parking garage, and can be accessed directly from Terminals1–3 via tunnel and from Terminal5 via shuttle bus.

Pace, Peoria Charter, Van Galder Bus Company, and Wisconsin Coach Lines operate bus service to O'Hare, stopping at the MMF.

O'Hare is directly served by Interstate 190, which offers interchanges with Mannheim Road (U.S. 12 and 45), the Tri-State Tollway (Interstate 294), and Interstate 90. I-90 continues as the Kennedy Expressway into downtown Chicago and becomes the Jane Addams Memorial Tollway northwest to Rockford and the Wisconsin state line.

Cargo facilities
There are presently two main cargo areas at O'Hare. The South Cargo Area was relocated in the 1980s from the airport's first air cargo facilities, located east of the terminal core, where Terminal5 now stands. Many of the structures in this new cargo area then had to be rebuilt, again, to allow for the OMP and specifically runway 10R/28L; as a result, what is now called the South Cargo Area is located between 10R/28L and 10C/28C. This large collection of facilities, in three sections (Southwest, South Central, and Southeast), was established mainly by traditional airline-based air cargo; Air France Cargo, American, JAL Cargo, KLM, Lufthansa Cargo, Northwest and United all built purpose-built, freestanding cargo facilities, although some of these are now leased out to dedicated cargo firms. In addition, the area contains two separate facilities for shipper FedEx and one for UPS.

The Northeast Cargo Area (NEC) is a conversion of the former military base (the Douglas plant area) at the northeast corner of the airport property. It is a new facility designed to increase O'Hare's cargo capacity by 50%. Two buildings currently make up the NEC: a 540000 sqft building completed in 2016, and a 240000 sqft building that was completed in 2017. A third structure will complete the NEC with another 150000 sqft of warehouse space.

The current capability of the cargo areas provide 2 e6sqft of airside cargo space with parking for 40 wide-body freighters matched with over 2 e6sqft of landside warehousing capability. O'Hare shipped over 1700000 t in 2018, fifth among airports in the U.S.

Other facilities
In 2011, O'Hare became the first major airport to build an apiary on its property; every summer, it hosts as many as 75 hives and a million bees. The bees are maintained by 30 to 40 ex-offenders with little to no work experience and few marketable skills; they are primarily recruited from Chicago's North Lawndale neighborhood. They are taught beekeeping but also benefit from the bees' labor, turning it into bottled fresh honey, soaps, lip balms, candles and moisturizers marketed under the beelove product line. More than 500 persons have completed the program, transferring to jobs in manufacturing, food processing, customer service, and hospitality; the repeat-offender rate is reported to be less than 10%.

The CDA's Airport Airfield Operations section is based out of the 150 ft tall prototype tower architect I.M. Pei designed for the FAA in the 1960s -1970s.

Major accidents and incidents
The following is a list of major crashes or incidents that occurred to planes at O'Hare, on approach, or just after takeoff from the airport:
 * On September 17, 1961, Northwest Orient Airlines Flight 706, a Lockheed L-188 Electra, crashed upon takeoff, killing all 37 on board.
 * On August 16, 1965, United Airlines Flight 389, a Boeing 727, crashed 30 mi east of O'Hare while on approach, killing all 30 on board.
 * On December 27, 1968, North Central Airlines Flight 458, a Convair CV-580, crashed into a hangar at O'Hare, killing 27 on board and one on the ground.
 * On December 20, 1972, North Central Airlines Flight 575, a Douglas DC-9, crashed upon takeoff after colliding with Delta Airlines Flight 954, a Convair CV-880 which was taxiing across the active runway; 10 passengers on the DC-9 were killed.
 * On May 25, 1979, American Airlines Flight 191, a McDonnell Douglas DC-10 on a Memorial Day weekend flight to Los Angeles International Airport, had its left engine detach while taking off from runway 32R, then stalled and crashed into a field some 4600 ft away. 273 died, including two on the ground, in the deadliest single-aircraft crash in United States history, and the worst aviation disaster in U.S. history prior to the September 11, 2001 attacks.
 * On March 19, 1982, a United States Air Force KC-135 Stratotanker crashed upon approach to O'Hare 40 mi northwest of the city (near Woodstock), killing 27 people on board.
 * On February 9, 1998, American Airlines Flight 1340, a Boeing 727, crashed upon landing from Kansas City, injuring 22 passengers.
 * On October 28, 2016, American Airlines Flight 383 aborted takeoff on runway 28R after a fire broke out in the right engine of the Boeing 767-300ER; 20 passengers and one flight attendant were injured.
 * On April 9, 2017, a passenger was forced off of a Republic-operated United Express flight in Chicago bound for Louisville. The passenger was escorted off the flight by Chicago Department of Aviation officers after he refused to give up his seat to an airline employee. He attempted to run back onto the aircraft but was removed. A video posted on social media showing him being injured and dragged off the plane led to a public outcry.

Music of Iraq

The music of Iraq or Iraqi music, (موسيقى عراقية), also known as the music of Mesopotamia, encompasses the music of a number of ethnic groups and musical genres. Ethnically, it includes Mesopotamian Arabic, Assyrian, Kurdish and the music of Turkmen, among others. Apart from the traditional music of these peoples, Iraqi music includes contemporary music styles such as pop, rock, soul and urban contemporary.

Iraq is recognized mainly for three instruments, the Oud, Iraqi Santur and Joza. The country's oud playing tradition has become an own school and a reference. It is illustrated specially by the figure of the acclaimed Munir Bashir. Other renowned Oudists are Naseer Shamma, Omar Bashir, Jamil Bachir, Ahmed Mukhtar, Rahim AlHaj, and Sahar Taha.

Instruments
In 1929, archaeologists led by the British archaeologist Leonard Woolley, representing a joint expedition of the British Museum and the University of Pennsylvania Museum of Archaeology and Anthropology, discovered the Lyres of Ur or Harps of Ur, which are considered to be the world's second oldest surviving stringed instruments when excavating the Royal Cemetery of Ur between from 1922 and 1934. They discovered pieces of three lyres and one harp in Ur, located in what was Ancient Mesopotamia, modern day Iraq. They are over 4,500 years old, from ancient Mesopotamia during the Early Dynastic III Period (2550–2450 BC). The decorations on the lyres are fine examples of the court art of Mesopotamia of the period.

Classical Iraqi music
Iraqi classical music necessitates some discussion of the social environment, as well as references to the poetry. Poetry is always rendered clearly. Poetry is the art of the Iraqis, and sung poetry is the finest of all. In Baghdad from 760 to 1260, writers spurned musical notation. The music is melodically modal, and moves in a stepwise motion with repeated notes. Use of the lower end of a melodic range is characteristic, as is the use of silence; one listens through the silence. Following a cadence, the singer moves up to the next range of pitches. An arch shape is discernible, and the work ends in the original mode.

Singers of the Baghdad Court were praised for their excellence in composition, their knowledge of history and songs, and their ornaments and innovations. There was support for female singers and orators, such as Arib, a skilled poet, calligrapher, lutenist, composer, and backgammon player who wrote more than one thousand songs. The common instrument (comparable in popularity to the piano or violin in the west) is the oud. Classical Iraqi music is identifiable by the genre/canon, and by how it is performed.

Historically, music would have been played for gatherings of men. With the advent of the sound recording industry, things have changed somewhat. Today one invites musicians to perform at weddings; by the first quarter of the century, concerts were being staged at concert venues.

Maqam
Across the Arab world, maqam refers to specific melodic modes. When a musician performs maqam performances, the performer improvises, based on rules. There are between fifty and seventy maqams, each with its own mood and characteristics, and many of which have sub-styles. Other characteristics of Iraqi music include a slow tempo, rhythmically free ornamentation or melodic lines, and predominantly minor modes. Instruments include qanun, riq, santur, darbuka, naqareh, ney, djose and oud. Baghdad's Chalgi ensembles typically include the djose and ney, and may also utilize an oud. Maqama texts are often derived from classical Arabic poetry, such as by Muhammad Mahdi al-Jawahiri, al-Mutanabbi and Abu Nuwas, or Persian poets like Hafez and Omar Khayyám. Some performers used traditional sources translated into the dialect of Baghdad, and still others use Arabic, Turkish, Armenian, Hebrew, Turkmen, Aramaic or Persian language lyrics.

History
The roots of modern Iraqi maqam can be traced as far back as the Abbasid Caliphate, when that large empire was controlled from Baghdad.

The pesteh, a kind of light song which concludes a maqam performance, has been popularized in the later 20th century, growing more prominent along with the rise of recorded music and broadcast radio. Among the most popular pesteh performers are the husband and wife Salima Pasha and Nazem Al-Ghazali.

The most popular modern singers of maqam are Rachid Al-Qundarchi (1887–1945), Youssouf Omar (1918–1987), Nazem Al-Ghazali (1920–1963), Salim Shibbeth (born 1908), Hassan Chewke (1912–1962), Najim Al-Sheikhli (1893–1938), Mohammed Al-Qubanchi (1900–1989), Hamid Al Saadi (1959-) and Farida Mohammad Ali (1963- ).

Modern era
In 1936, Iraq Radio was established by two of Iraq's most prominent performers and composers, the Kuwaiti-born Iraqi musicians, Saleh and Daoud al-Kuwaity with an ensemble, with the exception of the percussion player. The nightclubs of Baghdad also featured almost entirely Jewish musicians. At these nightclubs, ensembles consisted of oud, qanun and two percussionists while the same format with ney and cello were used on the radio.

One of the reasons for the predominance of Jewish instrumentalists in early 20th century Iraqi music was a prominent school for blind Jewish children, which was founded in the late 1920s by the great qanunji ("qanun player") Joseph Hawthorne (Yusef Za'arur) (דנדהי ללוואלד-יוסף זערור يوسف زعرور).

The most famous singer of the 1930s–1940s was perhaps Salima Pasha. The respect and adoration for Pasha were unusual at the time, since public performance by women was considered shameful and most female singers were recruited from brothels.

Numerous instrumentalists and singers of the middle and late twentieth century were trained at the Baghdad Conservatory.

In recent years the Iraqi school of oud players has become very prominent, with players such as Salman Shukur and Munir Bashir developing a very refined and delicate style of playing combining older Arabic elements with more recent Anatolian influences.

Pop music
Until the fall of Saddam Hussein, the most popular radio station was the Voice of Youth, which used to play the popular music of Iraq to continue the culture of the country. The station also played a mix of rock, hip hop and pop music, all of which had to be imported via Jordan due to international economic sanctions. Irish bands The Corrs and Westlife were especially popular. Iraq also produced a major pan-Arab pop star in exile in Kadim Al Sahir, whose songs include Ladghat-e Hayya, which was banned by Hussein for its racy lyrical content.

Other modern Iraqi singers include Ali Al Essawi, whose song Makhtuba became huge hit in the Arab world and made him famous throughout the region. Major artists include Shatha Hassoun, Rahma Mezher, Majid al-Muhandis, Hussam Al-Rassam, Rida Al Abdullah and Iraq's very own boy band Unknown to No One, as well as Acrassicauda, Iraq's first heavy metal band. There are also ethnic Assyrian singers such as Klodia Hanna, Ashur Bet Sargis and Linda George as well as a number of Kurdish, Turkmen, Yazidi, Dom and Armenian musicians such as Seta Hagopian.

Effect of 2003 Iraq War
After the 2003 invasion of Iraq and fall of Saddam Hussein, and with some religious figures coming to power, concerts were forbidden in areas considered as "conservative". However, since 2018, many concert were held in different areas throughout the country. In 2021, Babylon arts festival was held for the first time in almost 20 years. Performers were from Iraq, Middle East, Europe and Africa.

Raytheon

The Raytheon Company was a major U.S. defense contractor and industrial corporation with manufacturing concentrations in weapons and military and commercial electronics. It was previously involved in corporate and special-mission aircraft until early 2007. Raytheon was the world's largest producer of guided missiles. In April 2020, the Raytheon Company merged with United Technologies Corporation to form Raytheon Technologies, which changed its name to RTX Corporation in July 2023.

Raytheon was originally established in 1922, reincorporated in 1928, and adopted the Raytheon Company name in 1959. During 2018, the company had around 67,000 employees worldwide and annual revenues of approximately US$25.35 billion. More than 90% of Raytheon's revenues were obtained from military contracts and, as of 2012, it was the fifth-largest military contractor in the world. , it was the third largest defense contractor in the United States by defense revenue.

In 2003, Raytheon's headquarters moved from Lexington, Massachusetts, to Waltham, Massachusetts. The company had previously been headquartered in Cambridge, Massachusetts, from 1922 to 1928, Newton, Massachusetts, from 1928 to 1941, Waltham from 1941 to 1961 and Lexington from 1961 to 2003.

Early years
In 1922, Vannevar Bush, scientist and professor in the Department of Electrical Engineering at the Massachusetts Institute of Technology (MIT), along with engineer and physicist Laurence K. Marshall, and scientist Charles G. Smith, founded the American Appliance Company in Cambridge, Massachusetts. Its focus, which was originally on new refrigeration technology, soon shifted to electronics. The company's first product was a gaseous (helium) voltage-regulator tube that was based on Charles Smith's earlier astronomical research of the star Zeta Puppis. The electron tube was christened with the name Raytheon (a compound of Old French and Greek meaning 'light from the gods') and was used in a battery eliminator, a type of radio-receiver power supply that plugged into the power grid in place of large batteries. This made it possible to convert household alternating current to a regulated, high voltage direct current for radios and thus eliminate the need for expensive, short-lived batteries.

In 1925, the company changed its name to Raytheon Manufacturing Company and began marketing its rectifier, under the Raytheon brand name, with commercial success. In 1928 Raytheon merged with Q.R.S. Company, an American manufacturer of electron tubes and switches, to form the successor of the same name, Raytheon Manufacturing Company. By the 1930s, it had already grown to become one of the world's largest vacuum tube manufacturing companies. In 1933 it diversified by acquiring Acme-Delta Company, a producer of transformers, power equipment, and electronic auto parts.

During World War II
Early in World War II, physicists in the United Kingdom invented the magnetron, a specialized microwave-generating electron tube that markedly improved the capability of radar to detect enemy aircraft. American companies were then sought by the US government to perfect and mass-produce the magnetron for ground-based, airborne, and shipborne radar systems, and, with support from the Massachusetts Institute of Technology's Radiation Laboratory (recently formed to investigate microwave radar), Raytheon received a contract to build the devices. Within a few months of being awarded the contract, Raytheon had already begun to mass manufacture magnetron tubes for use in radar sets and then complete radar systems. At war's end in 1945 the company was responsible for about 80 percent of all magnetrons manufactured. During the war Raytheon also pioneered the production of shipboard radar systems, particularly for submarine detection. Raytheon ranked 71st among United States corporations in the value of World War II military production contracts.

Raytheon's research on the magnetron tube revealed the potential of microwaves to cook food. In 1945, Raytheon's Percy Spencer invented the microwave oven by discovering that the magnetron could rapidly heat food. In 1947, the company demonstrated the Radarange microwave oven for commercial use.

Raytheon was also a contractor for the mass-production of the newly invented miniature shock-resistant vacuum tubes used in proximity fuses. These tubes were difficult to manufacture and required rigorous attention to detail to avoid failure of the fuse.

After World War II
In 1946, the company expanded its electronics capability through acquisitions that included the Submarine Signal Company (founded in 1901), a leading manufacturer of maritime safety equipment. With its broadened capabilities, Raytheon developed the first guidance system for a missile that could intercept a flying target. In 1948 Charles Francis Adams IV was appointed to be the new President of the company and served until 1960. In 1948, Raytheon began to manufacture guided missiles. In 1950, its Lark missile became the first such weapon to destroy a target aircraft in flight. Raytheon then received military contracts to develop the air-to-air Sparrow and ground-to-air Hawk missiles, projects that received impetus from the Korean War. In later decades, it remained a major producer of missiles, such as the Patriot antimissile missile and the air-to-air Phoenix missile.

Raytheon made a foray into computers, producing the RAYDAC computer for the U.S.Navy which became operational in 1953. "Unfortunately, the machine was technically obsolete by the time it was operational." Also in 1953 the company began work on a follow-on, the RAYCOM, which was never completed. In 1954 it entered into a joint venture with Honeywell to form the Datamatic corporation. However it sold its interest to Honeywell a year later, before introduction of the DATAmatic 1000 system.

In 1958, Raytheon acquired the marine electronics company Applied Electronics Company, which significantly increased its strength in commercial marine navigation and radio gear, as well as less-expensive Japanese suppliers of products such as marine/weather band radios and direction-finding gear. In the same year, it changed its name to Raytheon Company.

During the post-war years, Raytheon also made generally low- to medium-powered radio and television transmitters and related equipment for the commercial market, but the high-powered market was solidly in the hands of larger, better-financed competitors such as Continental Electronics, General Electric and Radio Corporation of America.

In the 1950s, Raytheon began manufacturing transistors, including the CK722, priced and marketed to hobbyists.

In 1961, the British electronics company A.C. Cossor merged with Raytheon, following its sale by Philips. The new Company's name was Raytheon Cossor. The Cossor side of the organisation is still current in the Raytheon group.

In 1965, it acquired Amana Refrigeration, Inc., a manufacturer of refrigerators and air conditioners. Using the Amana brand name and its distribution channels, Raytheon began selling the first countertop household microwave oven in 1967 and became a dominant manufacturer in the microwave oven business.

In 1966, the company entered the educational publishing business with the acquisition of D.C. Heath and Company, marketing an influential physics textbook developed by the Physical Science Study Committee. Raytheon also manufactured the Apollo Guidance Computer, which was introduced that year and flew aboard all NASA Project Apollo missions.

In the late 1970s, Raytheon acquired McGraw-Edison's appliances division notable for the Speed Queen line of washers and dryers.

1980s
In 1980, Raytheon acquired Beech Aircraft Corporation, a leading manufacturer of general aviation aircraft founded in 1932 by Walter H. Beech. In 1993 the company expanded its aircraft activities by adding the Hawker line of business jets by acquiring Corporate Jets Inc., the business jet product line of British Aerospace (now BAE Systems). These two entities were merged in 1994 to become the Raytheon Aircraft Company. In the first quarter of 2007 Raytheon sold its aircraft operations, which subsequently operated as Hawker Beechcraft, and since 2014 have been units of Textron Aviation. The product line of Raytheon's aircraft subsidiary included business jets such as the Hawker 800XP and Hawker 4000, the Beechjet 400A, and the Premier I; the popular King Air series of twin turboprops; and piston-engine aircraft such as the Bonanza. Its special-mission aircraft included the single-turboprop T-6A Texan II, which the United States Air Force and United States Navy had chosen as their primary training aircraft.

1990s
In 1991, during the Persian Gulf War, Raytheon's Patriot missile received great international exposure, resulting in a substantial increase in sales for the company outside the United States. In an effort to establish leadership in the defense electronics business, Raytheon purchased in quick succession Dallas-based E-Systems (1995); Chrysler Corporation's defense electronics and aircraft-modification businesses, which had previously acquired companies such as Electrospace systems (1996) (portions of these businesses were later sold to L-3 Communications), and the defense unit of Texas Instruments, Defense Systems & Electronics Group (1997). Also in 1997, Raytheon acquired the aerospace and defense business of Hughes Aircraft Company from Hughes Electronics Corporation, a subsidiary of General Motors, which included a number of product lines previously purchased by Hughes Electronics, including the former General Dynamics missile business (Pomona facility), the defense portion of Delco Electronics (Delco Systems Operations), and Magnavox Electronic Systems.

Raytheon also divested itself of several nondefense businesses in the 1990s, including Amana Refrigeration, Raytheon Commercial Laundry (purchased by Bain Capital's Alliance Laundry Systems), and Seismograph Service Ltd (sold to Schlumberger-Geco-Prakla). On October 12, 1999, Raytheon exited the personal rapid transit (PRT) business as it terminated its PRT 2000 system due to the high cost of development and the lack of interest.

2000s
During the September 11 attacks of 2001, Raytheon had an office in the South Tower of the World Trade Center on the 91st floor. Their office, being 6 floors above where United Airlines Flight 175 collided with the building, was spared from the immediate collision, but was utterly destroyed in the subsequent collapse of the South Tower.

In November 2007, Raytheon purchased Sarcos for an undisclosed sum, seeking to expand into robotics research and production.

In September 2009, Raytheon purchased Bolt Beranek and Newman Inc. as a wholly owned subsidiary.

2010s
In December 2010, Applied Signal Technology agreed to be acquired by Raytheon for $490 million.

In October 2014, Raytheon beat rivals Lockheed Martin and Northrop Grumman for a contract to build 3DELRR, a next-generation long-range radar system, for the USAF worth an estimated $1 billion.

The contract award was immediately protested by Raytheon's competitors, Lockheed Martin and Northrop Grumman. After re-evaluating the bids following the protests, the USAF decided to delay awarding the 3DELRR EMD contract until 2017 and was to issue an amended solicitation at the end of July 2016. In 2017 the USAF again awarded the contract to Raytheon.

In May 2015, Raytheon acquired cybersecurity firm Websense, Inc. from Vista Equity Partners for $1.9 billion and combined it with RCP, formerly part of its IIS segment to form Raytheon|Websense. In October 2015, Raytheon|Websense acquired Foreground Security for $62 million. In January 2016, Raytheon|Websense acquired the firewall provider Stonesoft from Intel Security for an undisclosed amount and renamed itself to Forcepoint.

In July 2016, Poland's Defence Minister Antoni Macierewicz planned to sign a letter of intent with Raytheon for a $5.6 billion deal to upgrade its Patriot missile-defence shield.

In 2017, Saudi Arabia signed business deals worth billions of dollars with multiple American companies, including Raytheon.

In July 2019, Qatar's Ministry of Defense committed to acquire Raytheon's NASAM and Patriot missile defense systems.

2020s
In February 2020, Raytheon completed the first radar antenna array for the US Army's new missile defense radar, known as the Lower Tier Air and Missile Defense Sensor (LTAMDS), to replace the service's Patriot air and missile defense system sensor.

In April 2020, the company merged with United Technologies Corporation to form Raytheon Technologies. The merged company is headquartered in Arlington, Virginia rather than UTC's base in Farmington, Connecticut.

In July 2023, Raytheon Technologies renamed themselves to RTX Corporation and merged the Raytheon Intelligence & Space and Raytheon Missiles & Defense business segments to form a new Raytheon business segment.

Finances
For the fiscal year 2017, Raytheon reported earnings of US$2.024 billion, with an annual revenue of US$25.348 billion, an increase of 5.1% over the previous fiscal cycle. Raytheon's shares traded at over $164 per share, and its market capitalization was valued at over US$51.7 billion in November 2018.

Environmental record
Two lawsuits were filed against a Raytheon Company plant in St. Petersburg, Florida, due to concern with health risks, property values, and contamination in April 2008. Raytheon was given until the end of the month to independently test whether or not the groundwater that originated from its area was contaminated. According to the Florida Department of Environmental Protection (DEP), the groundwater contained carcinogenic contaminants, including trichloroethylene, 1,4-dioxane, and vinyl chloride. The DEP also reported that the clouds contained other toxins, such as lead and toluene.

In 1995, Raytheon acquired Dallas-based E-Systems, including a site in St. Petersburg, Florida. In November 1991, prior to Raytheon's acquisition, contamination had been discovered at the E-Systems site. Soil and groundwater had been contaminated with the volatile organic compounds trichloroethylene and 1,4-Dioxane. In 2005, groundwater monitoring indicated polluted groundwater was moving into areas outside the site. According to DEP documentation, Raytheon has tested wells on its site since 1996 but had not delivered a final report; therefore, it was given a deadline on May 31, 2008, to investigate its groundwater. Contamination in the area has not affected anyone's drinking water supply or health, yet due to negative local media coverage lawsuits are being filed with claims against Raytheon citing decreases in property values.

In another case, Raytheon was ordered by the Environmental Protection Agency (EPA) to treat groundwater at the Tucson Plant (acquired during the merger with Hughes) in Arizona since Raytheon used and disposed metals, chlorinated solvents, and other substances at the plant since 1951. The EPA further required the installation and operation of an oxidation process system to treat the solvents and make the water safe to drink.

On 9 August 2006, The Stream Contact Centre in Derry, Northern Ireland, which had a contract with Raytheon at the time, was attacked by protesters. They destroyed the computers, documents, and mainframe of the office, and proceeded to occupy it for eight hours prior to their arrest.

The activists were charged with criminal damage and affray under terrorism laws. The trial of six of the accused began May 19, 2008, in the Laganside Courts in Belfast. Colm Bryce, Gary Donnelly, Kieran Gallagher, Michael Gallagher, Sean Heaton, Jimmy Kelly, Paddy McDaid and Eamonn O'Donnell were acquitted of all charges on 11 June, with Eamonn McCann found guilty of the theft of two computer discs.

By 2013, the company was also awarded the Goal Achievement Award by the EPA for excellence in greenhouse gas management.
