1972 Chicago–O'Hare runway collision

American Airlines Flight 383 was a scheduled passenger flight from Chicago to Miami, which caught fire on the runway at Chicago O’Hare on October 28, 2016. The crew aborted their takeoff, evacuating everyone on board, of whom 21 were injured. The plane was a write-off. The incident was caused by the rupture of a disk in the starboard engine, with one fragment piercing the fuel tank in the wing. The investigation revealed the need for more stringent directives for ultrasonic inspection of engines.

Chicago O'Hare International Airport (IATA: ORD, ICAO: KORD, FAA LID: ORD), sometimes referred to as Chicago O'Hare, or simply O'Hare, is the main international airport serving Chicago, Illinois, located on the city's Northwest Side, approximately 17 miles (27 km) northwest of the Loop business district. Operated by the Chicago Department of Aviation and covering 7,627 acres (3,087 ha), O'Hare has non-stop flights to 214 destinations in North America, South America, the Caribbean, Europe, Africa, Asia, the Middle East, Oceania, and the North Atlantic region as of November 2022. As of 2022, O'Hare is considered the world's most connected airport.Designed to be the successor to Chicago's Midway International Airport, itself 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 from 1963 to 1998; today, it is the world's fourth-busiest airport for passenger counts, serving 54 million passengers in 2021. 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, or taxis by Interstate 190 (Kennedy Expressway), which goes directly into the airport. O'Hare serves as a major hub for both United Airlines (which is headquartered in Willis Tower) and American Airlines. It is also a focus city for Spirit Airlines.

On March 24, 2014, a Chicago Transit Authority (CTA) passenger train overran the bumper at O'Hare station, injuring 34 people.

O'Hare is a Chicago "L" station located at O'Hare International Airport, 17 miles (27 km) northwest of The Loop. The northwestern terminus of the Chicago Transit Authority's Blue Line, it is a subway station with two island platforms serving three tracks, situated under the parking garage for Terminals 1, 2, and 3. Trains are scheduled to depart from O'Hare every 2–7 minutes during rush-hour periods and take about 40 minutes to travel to the Loop. It is the westernmost station of the Chicago 'L' system. It is also the only station without coordinates in Chicago's grid system, the only underground terminus, and is the only terminal that does not directly connect to any CTA or Pace buses. It is also one of two terminals (the other being Dempster–Skokie on the Yellow Line) that does not have a yard assigned to it (the yard is located at Rosemont, one stop east).

Northwest Orient Airlines Flight 706 was a Lockheed L-188 Electra aircraft, registration N137US, which crashed on take-off from Chicago's O'Hare International Airport September 17, 1961. All 37 on board were killed in the accident. Flight 706 began its day in Milwaukee, Wisconsin, and was scheduled to stop at Chicago before travelling to Tampa, Fort Lauderdale, and Miami, Florida. It arrived at Chicago in the early morning and left soon afterwards, being cleared for takeoff at 8:55 AM. Takeoff was normal until the aircraft reached the altitude of 100 feet above ground level, when witnesses noticed a slight change in the sound of the Electra's engines. The aircraft began a gentle bank to the right as the starboard wing began to drop. The bank angle increased to 35°; at that point the tower controllers picked up a garbled broadcast believed to be from the pilots. The aircraft climbed to approximately 300 feet but continued to bank, eventually reaching a bank angle of over 50°. At that point, the starboard wing nicked a series of high-tension power lines running along the south boundary of the airport; shortly after that, the aircraft struck an embankment and cartwheeled onto its nose. The forward fuselage broke off, the plane pancaked and skidded, then launched into the air and slammed nose-first into the ground, falling over on its back and exploding into a ball of flame. The accident took less than two minutes from the beginning of takeoff until the final crash. Investigators with the Civil Aeronautics Board determined that the cable physically connecting the first officer's control wheel to the aileron boost unit had disconnected. This had caused the ailerons to put the aircraft in a starboard-wing-down attitude, and had prevented the pilots from being able to correct the bank. The cables attaching the pilots' control wheels to the aileron boost unit had been removed two months before the accident during routine maintenance; a safety cable that held part of the assembly together had not been replaced when the cables were hooked back up. The contact slowly separated, until it completely failed during the takeoff sequence.

The 928th Airlift Wing is an inactive United States Air Force Reserve unit. It was last active with the Twenty-Second Air Force at O'Hare Air Reserve Station, Illinois, where it was inactivated on 1 July 1997.
