North Central Airlines Flight 458

O'Hare, located on the far north side of Chicago, is one of the city's 77 community areas. O'Hare International Airport is located within the boundaries of this community area. This community area is the only one that extends outside Cook County; the western edge (an area comprising the southwest part of the airport) is in DuPage County. The area is a transportation hub containing O'Hare International Airport as well as major roads such as Interstate 90, its auxiliary Interstate 190, Interstate 294, Illinois Route 72, Illinois Route 171, U.S. Route 12 and U.S. Route 45. This allows the O'Hare neighborhood, combined with the nearby suburb of Rosemont, to work as an edge city.

American Airlines Flight 191 was a regularly scheduled domestic passenger flight in the United States operated by American Airlines from O'Hare International Airport in Chicago, Illinois, to Los Angeles International Airport in Los Angeles, California. On the afternoon of May 25, 1979, the McDonnell Douglas DC-10-10 operating this flight was taking off from runway 32R when its left engine detached, causing loss of control, and it crashed less than a mile (1.6 km) from the end of the runway. All 258 passengers and 13 crew on board were killed, along with two people on the ground. With 273 fatalities, it is the deadliest aviation accident to have occurred in the United States.The National Transportation Safety Board (NTSB) found that as the aircraft was beginning its takeoff rotation, engine number one (the left engine) separated from the left wing, flipping over the top of the wing and landing on the runway. As the engine separated from the aircraft, it severed hydraulic fluid lines that lock the wing's leading-edge slats in place and damaged a 3-foot (0.9 m) section of the left wing's leading edge. Aerodynamic forces acting on the wing resulted in an uncommanded retraction of the outboard slats. As the aircraft began to climb, the damaged left wing – with no engine – produced far less lift (stalled) than the right wing, which had its slats still deployed and its engine providing full takeoff thrust. The disrupted and unbalanced aerodynamics of the aircraft caused it to roll abruptly to the left until it was partially inverted, reaching a bank angle of 112°, before crashing in an open field by a trailer park near the end of the runway. The engine separation was attributed to damage to the pylon structure holding the engine to the wing, caused by improper maintenance procedures used at American Airlines.

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.

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).

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

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.

On December 20, 1972, North Central Airlines Flight 575 and Delta Air Lines Flight 954 collided on a runway at O'Hare International Airport in Chicago, Illinois, in the United States. Ten people died – all on the North Central aircraft – and 17 were injured in the accident.: 1  This was the second major airliner accident to happen in Chicago in December 1972; the other was United Airlines Flight 553, which crashed twelve days earlier on approach to Midway Airport.

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.

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.

Lake Opeka is a small, 40 acres (16 ha) lake in Des Plaines, Illinois. On the shores of Lake Opeka, Lake Park is a 60 acres (24 ha) park which offers a wide variety of outdoor recreational opportunities for all age groups, administered by the Des Plaines Park District, with an 18-hole par-3 golf course. On the northern bank is Good Shepherd Lutheran Church. Jogging paths run around the east side, where a band shelter is located amongst picnic tables and grills, exercise stations and a playground. The southern end has a volleyball sand pit. Rumor has it that there is a jeep underwater along with an old road.Fishing is allowed. Bass, bluegill and occasional northern pike are caught. There are small sailboats and paddleboats using the lake. Many ducks are on the water, some large carp and occasional turtles. 460 man-hours were spent removing submerged and surface vegetation from the lake, to prevent its becoming a threat to aquatic life (due to its using up the oxygen supply when decomposing). The vegetation consisted of the native slender naiad (Najas flexilis), and an excessive amount of filamentous algae.
