O'Hare International Airport (IATA: ORD, ICAO: KORD, FAA LID: ORD), also known simply as O'Hare Airport or O'Hare, is a major airport located in the northwestern-most corner of Chicago, Illinois, United States, 17 miles (27 km) northwest of the Chicago Loop. It is the largest hub of United Airlines (whose headquarters is in Downtown Chicago) and the second-largest hub of American Airlines (after Dallas/Fort Worth). It is operated by the City of Chicago Department of Aviation, associated with an umbrella regional authority.

In 2005, the airport had 972,246 aircraft operations, an average of 2,663 per day (64% scheduled commercial, 33% air taxi, 3% general aviation and <1% military).^[1] Prior to 2005, O'Hare was the world's busiest airport in terms of takeoffs and landings. That year, mainly due to limits imposed by the federal government to reduce flight delays at O'Hare,^[3] Hartsfield-Jackson Atlanta International Airport became the busiest by that metric. O'Hare currently accounts for over a sixth of the nation's total flight cancellations.^[4] O'Hare International Airport is the second busiest airport in both the United States and the world, behind Hartsfield-Jackson Atlanta International Airport with 76,248,911 passengers passing through the airport in 2006; a -0.3% change from 2005. ^[5] O'Hare also has a strong international presence, with flights to more than 60 foreign destinations. O'Hare was ranked fourth in 2005 of the United States' international gateways, with only John F. Kennedy International Airport in New York City, Los Angeles International Airport, and Miami International Airport serving more foreign destinations.

O’Hare International Airport was voted the Best Airport in North America for the past nine years by readers of the U.S. Edition of Business Traveler Magazine (1998 - 2003), and Global Traveler Magazine (2004 - 2007), marking the tenth year in a row O'Hare has earned the top honor. ^[6]

Although O'Hare is Chicago's primary airport, Chicago Midway International Airport, the city's second airport, is about six miles closer to the Loop, the main business and financial district.

History

The airport was constructed between 1942 and 1943 as a manufacturing plant for Douglas C-54s during World War II. The site was chosen for its proximity to the city and transportation. The two million square-foot (180,000 m²) factory needed easy access to the workforce of the nation's then-second-largest city, as well as its extensive railroad infrastructure. Orchard Place was a small pre-existing community in the area, and the airport was known during the war as Orchard Place Airport/Douglas Field (hence the call sign ORD). The facility was also the site of the Army Air Force's 803 Special Depot, which stored many rare or experimental planes, including captured enemy aircraft. These historic aircraft would later be transferred to the National Air Museum, going on to form the core of the Smithsonian Air and Space Museum's collection.

Air Traffic Control Towers
The new FAA control tower (right) opened in early 1997. The old tower (left) is now used by the City of Chicago, to manage city vehicles engaged in ground operations.

Douglas Aircraft Company's contract ended in 1945, and though plans were proposed to build commercial aircraft, the company ultimately chose to concentrate production on the west coast. With the departure of Douglas, the airport took the name Orchard Field Airport. In 1945, the facility was chosen by the City of Chicago as the site for a facility to meet future aviation demands. Though its familiar three-letter IATA code ORD still reflects the early identity of the airport, it was renamed in 1949 after Lt. Cmdr. Edward "Butch" O'Hare, a World War II flying ace who was awarded the Medal of Honor. (See also: Illinois World War II Army Airfields)

By the early 1950s, Chicago Midway International Airport, which had been the primary Chicago airport since 1931, had become too small and crowded despite multiple expansions and was unable to handle the planned first generation of jets. The City of Chicago and FAA began to develop O'Hare as the main airport for Chicago's future. The first commercial passenger flights were started there in 1955, and an international terminal was built in 1958, but the majority of domestic traffic did not move from Midway until completion of a 1962 expansion of O'Hare. The arrival of Midway's former traffic instantly made O'Hare the new World's Busiest Airport, serving 10 million passengers annually. Within two years that number would double, with more people passing through O'Hare in 12 months than Ellis Island had processed in its entire existence. In 1997, annual passenger volume reached 70 million; it is now approaching 80 million. At this time of writing, United serves its flagship hub with 650 daily departures, but the carrier's utilization of O'Hare peaked at over 1,000 daily flights in 1994^[7].

O'Hare Airport is municipally connected to the city of Chicago via a narrow strip of land, approximately 200 feet wide, running along Higgins Rd from the Des Plaines river to the airport. This land was annexed into the city limits in the 1950s to assure the airport was contiguous with the city to keep it under city control. The strip is bounded on the north by Rosemont and the south by Schiller Park.[2] The CTA Blue Line was extended to the airport in 1984.

Accidents and Incidents

Accidents

1057 fatalities have occurred as a result of accidents en route to or from Chicago O'Hare. [3]

• On February 9, 1998, American Airlines Flight 1340 crashed upon landing in Chicago from Kansas City International Airport injuring 22 passengers. [4]
• On October 31, 1994, American Eagle Flight 4184 crashed upon approach into Chicago O'Hare Airport in Northwestern Indiana, killing all 68 passengers on board. [5]
• On September 8, 1994, USAir Flight 427 departed O'Hare and crashed upon initial approach into Pittsburgh, PA, killing all 132 passengers on board. [6]
• On July 19, 1989, United Airlines Flight 232 from Denver en route to Chicago, crash landed in Sioux City, Iowa, killing 111 people on board. [7]
• On August 10, 1986, American Trans Air Flight 131 Exploded on the tarmac, destroying the plane. [8]
• On March 19, 1982, USAF Flight Crashed upon approach to O'Hare just north of the city, killing 27 people on board. [9]
• On May 25, 1979, American Airlines Flight 191 crashed upon takeoff from Chicago en route to Los Angeles International Airport in Los Angeles, California, killing all 271 people on board and two people on the ground. The crash remains the deadliest single-aircraft crash in United States history, and the worst aviation disaster in the nation before 9/11. [10]
• On December 20, 1972, North Central Airlines Flight 575 crashed upon takeoff at Chicago O'Hare Airport, killing 10 passengers. [11]
• On December 27, 1968, Convair Flight 458 crashed into a hangar at Chicago O'Hare killing 27 onboard and 1 on the ground. [12]
• On August 16, 1965, United Airlines Flight 389 en route to Chicago O'Hare crashed 30 miles east of Chicago O'Hare killing all 30 onboard. [13]
• On September 17, 1961, Northwest Orient Flight 706 snagged powerlines and crashed upon takeoff at Chicago O'Hare killing all 37 onboard. [14]

Incidents

• On October 8, 2001, on American Airlines Flight 1238, en route from Los Angeles to Chicago, a psychotic passenger stormed the cockpit 40 minutes before landing in Chicago, causing the plane to drop sharply and causing a panic. In light of the fear ignited by 9/11, flight crew and passengers were quick to wrestle the man to the ground and subdue him. Additionally, a distress signal was sent by the pilots, causing two F-16s to race at supersonic speeds to intercept and escort the aircraft to O'Hare International Airport. This caused a sonic boom in Chicago's northwest suburbs, startling millions of residents. [15]
• On May 8, 2002, alleged Al-Qaida member Jose Padilla was arrested after the plane he was on landed at the airport for allegedly being a scout for a plot to plant a dirty bomb.
• On the afternoon of November 7, 2006, a group of United Airlines workers reported seeing an unidentified flying object near gate C-17.^[8] Witnesses stated the object hovered over them before shooting up through clouds. The Federal Aviation Administration was notified of the incident; however, FAA controllers denied seeing anything and a preliminary check of radar found nothing out of the ordinary. The FAA concluded that the object was a weather phenomenon.

Modernization plan

O'Hare's high volume and crowded schedule can lead to long delays and cancellations that, due to the airport being a major hub, can affect air travel across the United States. Official reports rank O'Hare as the least punctual airport in the United States based on percentage of delayed flights. In 2004, United Airlines and American Airlines agreed to modify their schedules to help reduce congestion caused by clustered arrivals and departures. Because of the air traffic departing, arriving, and near the airport, air traffic controllers at O'Hare and its nearby facilities are among the leaders in the world in terms of number of controlled flights per hour.

City management has committed to a $6 billion capital investment plan to increase the airport's capacity by 60% and decrease delays by an estimated 79 percent[16]. This plan was approved by the FAA in October 2005 and will involve a reconfiguration of the airfield and addition of terminal space. Four runways will be added and two decommissioned in order to give the airfield an eight-runway parallel 6+2 configuration similar to that in Dallas. This plan is essential in alleviating the airport's flight limits so that its passenger and cargo numbers will not be eclipsed by other airports.

The Modernization Plan is now under construction, and an additional runway and Air Traffic Control Tower were commissioned on November 20, 2008. The new north runway, designated 9L/27R, will initially serve as a foul weather arrival runway, addressing one of O'Hare's primary causes of delay. An extension of Runway 10/28 (formerly 9R/27L) to 13,000 feet was opened in September, 2008, facilitating the shortening and eventual closure of the equally long Runway 14R/32L.

Concept planning, presently unfunded, encompasses expansion of Terminals 3 and 5, and construction of a new west terminal with western access into the airport.

Some land acquisition is necessary for the modernization, requiring approximately 2,800 residents to be relocated. The program will expand the airport's capacity to over 3,800 operations per day, up from the present capacity of 2,700 and will vastly increase passenger throughput. It will also improve the ability of very large aircraft such as the A380 to operate.

Flight caps in place since 2004 will be allowed to expire on October 31, 2008. Ironically, American Airlines plans to eliminate over 60 daily flights at O'Hare because of soaring fuel prices. United has announced similar cutbacks. Recent worldwide economic difficulties further complicate the forecasts for airport demand.

Resistance and alternatives

The neighboring communities of Bensenville and Elk Grove Village have been centers of resistance to the expansion plan, in which some residents and businesses will be required to relocate. Bensenville and Elk Grove Village formed the Suburban O'Hare Commission [17] to fight the expansion. So far, they have not had much success. The commission did receive a temporary injunction against portions of the city's expansion project; however, it was soon overturned. The Suburban O'Hare Commission has also been instrumental in pushing for a third regional airport in south suburban Peotone, which it claims would alleviate congestion at O'Hare. However, no airline has committed to the proposed airport, and planning efforts moved very slowly during 2007-2008.

In 1995, the Chicago/Gary Airport Compact was signed by the cities of Chicago and Gary, Indiana, creating a new administration for the Gary/Chicago International Airport just across the state line. While markedly smaller than the proposed Peotone site, this airport already has more land and a longer main runway than Midway Airport. Gary is also many miles closer than Peotone to downtown Chicago. In addition public transportation is already in place to the Loop via the South Shore Line. Indiana and the FAA have provided significant funding for a Gary runway expansion, currently under construction.

Chicago Rockford International Airport (RFD) in Rockford, Illinois has also marketed itself as an alternative for congestion at O'Hare. However, it is at least a 1-1/2 hour trip to Rockford from the Chicago Loop. Currently there is no direct transportation service from downtown Chicago or O'Hare to the Chicago Rockford International Airport, but airline service at the airport continues to grow. Larry Morrissey, the current mayor of Rockford, has pushed for a high-speed rail connection between the two airports to make the Rockford airport a more convenient alternative to O'Hare.

General Mitchell International Airport (MKE) in Milwaukee, WI has consistently attempted to increase its usage by Chicago and Northern Illinois customers. There is a direct Amtrak rail service connecting Chicago with Mitchell Airport. The trains operate 7 round trips each day, taking under 75 min. from the Chicago loop.

Terminals, airlines and destinations

O'Hare International Airport terminal map

O'Hare International has four passenger terminals. Two or more additional terminal buildings are envisioned. There is the possibility of a large terminal complex for the west side of the field, with access from I-90 and/or the Elgin-O'Hare Expressway, if the runway reconfiguration is completed.

United Airlines and United Express is the largest airline at Chicago O'Hare carrying 48.79% of the passengers. American Airlines and American Eagle is the second largest carrying 39.89% of passengers. [18]

The original 1955 passenger terminal for international flights, was replaced with the modern Terminal 1, designed by Helmut Jahn, in 1987.

Terminal 2

Terminal 2 Layout

Terminal 2 was built in a large airport expansion in 1962, along with the original portion of Terminal 3.

Terminal 2 was United's sole terminal until the current Terminal 1 was built. In the 1960s/70s/80s it served United, Ozark, Braniff, Eastern, Northwest, Continental and Piedmont. In addition to Concourses E/F (which remain today), there was also an 11-gate Concourse D, which was demolished to make room for new Terminal 1.

Terminal 2 provides 30 gates on 2 concourses:

Concourse E

Concourse E has 16 Gates: E1, E1A, E2, E2A, E3, E4, E6–E15

United Airlines runs a shuttle service between Concourse E and Concourse C. The shuttles are accessed via stairways near Gate E-2A and Gate C-9. Shuttles run every 5-7 minutes between 5:30am and 10:00pm.

Concourse F

Concourse F has 14 gates, however several gates can handle multiple flights at the same time, effectively bringing aircraft capacity to 26: F1(A-D), F2(B-D), F4(A,B), F5, F6(A,B), F7B, F8-F10, F11(A-E), F12, F12(A-C), F14.

Gates with the alpha designation in parentheses are those that board/disembark passengers through a single doorway. Passengers board/disembark aircraft using airstairs, walking along designated pathways, utilizing stairs/elevators to access the gate area. United Airlines is in the process of converting these "outside operations" gates used by United Express into jet bridge operations to increase passenger comfort and ultimately enhance safety and security.

Additional gates - F5B & F7A - are currently under construction which will increase capacity to 28 aircraft. Construction of these gates are scheduled to finish before summer.

Terminal 3

Terminal 3 provides 77 Gates on 4 Concourses:

Terminal 3 was also built in the 1962 capital program. During the 1960s, and pre-airline deregulation, Concourse L was home to Delta Air Lines. Concourse H & K served American while Concourse K also served the large "regional" carrier North Central. Concourse G served TWA, with a few gates reserved for Air Canada. Terminal 3 was significantly expanded in 1983, with the construction of Concourse L. Renovation were recently completed, which ran from January 2004 to Late Fall 2007.

Terminal 4

Terminal 4 was O'Hare's interim international terminal from 1984 until 1993, located on the ground floor of the main parking garage. International passengers would check in at Terminal 4 and be taken directly to their aircraft by bus. Since the opening of Terminal 5, Terminal 4 has been changed into the airport's facility for CTA buses, hotel shuttles, and other ground transportation. The T4 designation will be used again in the future as new terminals are developed.

Terminal 5 (International Terminal)

Terminal 5 provides 21 Gates on 1 Concourse.

There are two main cargo areas at O'Hare that have warehouse, build-up/tear-down and aircraft parking facilities. The Southwest Cargo Area, adjacent to Irving Park Road, accommodates over 80% of the airport's all-cargo flights, divided among 9 buildings in two tiers. The North Cargo Area, which is a modest conversion of the former military base (the 1943 Douglas plant area), also receives air freighters. It is adjacent to the northern portion of Bessie Coleman Drive.

Two satellite cargo areas have warehouse and build-up/tear down facilities, but aircraft do not park at these. Freight is trucked to/from aircraft on other ramps. The South Cargo Area is along Mannheim Road. The East Cargo Area, adjacent to Terminal 5, was formerly the airport's only cargo section but has now mostly evolved into an airport support zone.

Although all-cargo flights are important, an even greater amount of global air cargo flies in the cargo holds of passenger aircraft.

Facilities

Runways

Runway layout at ORD

There are 6 primary air carrier runways, arranged tangentially in 3 pairs of parallel sets. The largest is Runway 14R-32L, 13,000' x 200'. Runways 14L-32R, 14R-32L, 9L-27R and 10-28 have Category III ILS (Instrument Landing System). All other runway approaches except 4L have full Category I ILS.

All but one of O'Hare's runways intersect, which can create problems in times of inclement weather, congestion at the airport, or high winds. There have been several near-aircraft collisions at O'Hare in recent years. The proposed redevelopment, which essentially eliminates active runway intersections, is intended to alleviate collision hazards at O'Hare.

Three runways of the original 1943 airfield's four have been upgraded to modern standards. Additional runways were constructed in 1955, 1968, 1971 and 2008. In 2003, old Runway 18-36 was permanently closed—its short length and problematic placement no longer justified its continued certification. Runway 18-36 is now shown as taxiway WT on current airport charts.

The proposed redevelopment would entail removal of the 2 northwest–southeast runways, construction of 4 additional east–west runways, and extension of the 2 existing east–west runways. The two existing northeast–southwest runways would be retained.

Runway 32L is sometimes used for departures in a shortened configuration. Planes access the runway from its intersection at taxiway T10 (common) or taxiway M (not common). This shortens the effective length of the runway but allows operations on runway 10-28 to continue without restriction.

O'Hare has a voluntary nighttime (2200-0700) noise abatement program in place. http://www.ohare.com/cnrc/ohare/o_noise_flyquiet.shtm

The proposed runway re-configuration program at O'Hare would also improve the airport for the A380 Super-Jumbo aircraft. As part of the runway re-configuration program, on July 5, 2007, the runway previously designated 9R-27L became Runway 10-28, and on August 30, 2007, Runway 9L-27R became 9R-27L. ^[11]

On September 25, 2008, a 3,000 foot extension to 10-28 was opened. ^[12]

Access to airport

• Road vehicles enter and exit via I-190, which branches off I-90 (the Kennedy Expressway) leading to downtown Chicago. Cars may also access the airport locally from Mannheim Road, the airport's eastern boundary. Aside from cargo access on its south side, all airport traffic travels through the east side of the airport.
• Subway trains from the Blue Line of the CTA's 'L' depart the terminal from an underground station that opened on September 3, 1984.
• Commuter trains from the Metra North Central Service at the O'Hare Transfer station, which is connected to the Airport Transit System via a shuttle bus.

Intra-airport transportation

Main article: Airport Transit System

Airport Transit System with Hilton Hotel in Background

Access within the airport complex can be accomplished using O'Hare's Airport Transit System (ATS), a 2.5 mi (4 km) long automated people mover system that operates 24 hours a day, connecting all four terminals and the remote parking lots. The system began its operation in 1993, and will be soon undergoing a US $90 million enhancement to add 24 new cars and to extend the line to a new remote parking garage.

Other facilities

A large air cargo complex on the southwest side of the field was opened in 1984, replacing most of the old cargo area, which stood where Terminal 5 now exists.

The hangar area has multiple buildings capable of fully enclosing aircraft up to the size of the Boeing 747.

USAF Use

The original Douglas plant on the northeast side evolved into a United States Air Force Air National Guard and Air Force Reserve facility after World War II.

Beginning in 1947, the airfield was assigned to Continental Air Command (ConAC). The 338th Bombardment Group flew B-29 Superfortresses from the airfield between 12 Jun 1947 - 27 Jun 1949. The B-29s were replaced by the 437th Troop Carrier Group, flying Curtiss C-46 Commandoes until being activated for the Korean War on 14 Mar 1951. It's aircraft and personnel were deployed to various units in South Korea and Japan, with the group being inactivated immediatley afterwards.^[13]

During the Korean War, the ConAC reserve units were withdrawn and O'Hare was reassigned to Air Defense Command's Central Air Defense Force.^[14]. The 62d Fighter-Interceptor Squadron was transferred to the station flying F-86 Sabres. ^[15][16] The 62d FIS remained at O'Hare until 1 Oct 1959, becoming part of the ADC 56th Fighter Group later being upgraded to the F-86D interceptor version of the Sabre.^[17] In addition, the federalized Oregon Air National Guard 142d Fighter-Interceptor Wing, was stationed at O'Hare from 1 Mar 1951 - 6 Feb 1952.

Other Air Defense Command squadrons assigned to the 56th FIW at O'Hare Airport were the 42d Fighter-Interceptor Squadron (1953-1955) (F-86D) and the 63d Fighter-Interceptor Squadron (1955-1958) (F-86D/L)^[17] In 1960, the need for active duty Air Defense bases was diminishing and the Air Force inactivated its active-duty Air Defense Command units at O'Hare and returned the station back to Continental Air Command (later resesignated Air Force Reserve) to base reserve units under the 2840th Air Reserve Training Wing.^[18]

The USAF facilities closed in 1998 and is now being redeveloped for cargo and general aviation. Signature Flight Support services private aircraft in this area.
