Willow Run Airport (IATA: YIP, ICAO: KYIP) is in Van Buren Charter Township and in Ypsilanti Township, near Ypsilanti, Michigan, that serves freight, corporate, and general aviation. No airlines schedule flights to Willow Run, it being too near Detroit Metropolitan Wayne County Airport.
Opened in 1942, "Willow Run" was synonymous with the American industrial effort that contributed so much to Allied victory in World War II. Operated by the Ford Motor Company, the Willow Run manufacturing plant produced a total of 8,685 B-24 Liberator heavy bombers, completed and in kit form, before closure in April 1945; Willow Run produced more Liberators than either plant owned by the plane's designer, Consolidated Aircraft.
Today the Yankee Air Museum, in one of the airport hangars, has a large collection of vintage aircraft.

Willow Run Airport has four runways, a continuously staffed FAA control tower, and US Customs operations; it is one of two facilities operated by the Wayne County Airport Authority, the other being Detroit Metropolitan Wayne County Airport, which replaced Willow Run as the major commercial airport for the region starting in 1958. Worldwide cargo airlines Kalitta Air and National Airlines are based at Willow Run Airport.
Willow Run Airport was named for a small stream that meandered through pastureland and woods until the late-1930s. Automobile pioneer Henry Ford bought the property that became the airport's runways and taxiways in 1931, and used it for almost a decade as farmland for a “social engineering” experiment that brought inner-city boys to Willow Run Farm to learn about nature, farming tasks, and the rural way of life. The residents at the Willow Run farms planted, tended, and harvested crops as well as running a maple syrup operation, and sold their products at the farm market on the property. In the process, the boys learned self-discipline and the values of hard work, and benefited from the fresh air that they had not been able to experience while growing up in congested cities.
World War II
See the Willow Run article for further details of manufacturing at the site.
The coming of World War II to Europe and the Fall of France in 1940 alarmed many in the United States, and in spite of an official policy of American neutrality, a number of government officials began preparing for the possibility of United States involvement. Henry Ford, himself an isolationist, was prevailed upon in the spring of 1941 to accept a contract to build B-24 Liberator heavy bombers for the Army Air Forces, under license from the plane's designer Consolidated Aircraft. He chose as the site his Willow Run Farm and commenced building a massive industrial plant that became the Willow Run manufacturing complex. Architect Albert Kahn designed the main structure, which had 3,500,000 square feet (330,000 m2) of factory space, and an aircraft assembly line over a mile long. It was thought to be the largest factory under one roof anywhere in the world.
To meet projected demand for the B-24, in early 1941 the Federal government established the Liberator Production Pool Program; Ford joined the program shortly thereafter. Although the Ford Trimotor had been a success in the 1920s, the company had since shied away from aviation, and initially, Ford was assigned to provide B-24 components with final assembly performed by Consolidated at its Fort Worth plant, or by fellow licensee Douglas Aircraft at its Tulsa, Oklahoma plant. However, in October 1941 Ford received permission from Consolidated and the Army to assemble complete Liberators on its own at its new Willow Run facility. Even then it would take nearly a year before finished Liberators left the factory.
The Willow Run plant was gigantic. It covered 65 acres (26.3 ha) and was almost a quarter of a mile wide and a half-mile long. The production line had a 90-degree turn at roughly its two-thirds mark; overhead views suggest this was to avoid encroaching on the airfield's taxiways, while others contend that Ford's construction managers sought to keep the plant and its equipment inside Washtenaw County, where property tax assessments were lower than neighboring Wayne County.
The Willow Run bomber plant had many problems at startup, due in part to the mindsets and technical skills of both management and labor, who were each accustomed to the requirements of auto production, finding it difficult at first to adapt to the higher precision required in aircraft production. The plant at Willow Run had labor problems, in particular high absentee rates and rapid employee turnover; the factory was nearly an hour's drive from Detroit, and the imposition of wartime gasoline and tire rationing had made the daily commute difficult. In one month Ford had hired 2900 workers but had lost 3100. Ford officials were as a rule anti-union, and Willow Run experienced one serious strike.
Willow Run transitioned to production of the B-24H in June 1943; these were the first Willow Run Liberators to see combat in numbers. After another year, by which time the factory had begun producing the B-24J (from April 1944), the Army determined that Consolidated's San Diego plant and Willow Run could meet future requirements for Liberators. The Boeing B-29 Superfortress was taking over the long-range bombing mission in the Pacific theater and no new B-24 units were programmed for deployment in the Europe, the Mediterranean or in the CBI, the other theaters of the war.
By fall 1944 Willow Run had moved from the B-24L to the B-24M, the last Liberator to be built in significant numbers. Willow Run shut down production in May 1945, after the end of the war in Europe; 6,972 Liberators had been built at Ford, and 1,893 sets of knock-down parts were provided to Consolidated and Douglas for assembly, for a total of 8,685 aircraft.
Army Air Forces support and post-production activities
At the request of the government, Ford began to decentralize operations and many parts were assembled at other Ford plants as well as by the company's sub-contractors, with the Willow Run plant concentrating on final aircraft assembly. Ford's production managers coordinated their activities with an Army Air Forces support unit, the 484th Base Headquarters and Base Squadron. The bugs were eventually worked out of the manufacturing processes, and by 1944, Ford was rolling a Liberator off the Willow Run production line every 63 minutes, 24 hours a day, 7 days a week.
After their manufacture, the next step in the process was the delivery of the aircraft to the squadrons. This was done at Willow Run by 1st Concentration Command (1st CC). The 1st CC was responsible for completing the organization and equipment of tactical and combat bombardment squadrons prior to their deployment to the overseas combat theaters. It also provided a final inspection of the aircraft and make any appropriate final changes; i.e., install long-range fuel tanks, remove unnecessary equipment, and give it a final flight safety test.
While the planes were being serviced and made ready for overseas movement, personnel for these planes were also being processed. Pilots, co-pilots, navigators and crew chiefs were assigned as a crew for each aircraft. Paperwork was handled, necessary specific B-24 life support equipment was issued and some technical training for supporting the aircraft accomplished.
Once production began, it became difficult to introduce changes dictated by field experience in the various overseas theaters onto the production line in a timely fashion. Consequently, newly constructed Liberators needed modifications for the specific geographic areas they were to be flown in combat. For this reason, a series of Air Technical Service Command modification centers were established for the incorporation of these required theater changes into new Liberators following their manufacture and assignments. There were seven known modification centers: Consolidated/Fort Worth; Oklahoma City Air Materiel Center at Tinker Field, Tucson Modification Center at Davis-Monthan Field; the Birmingham Depot in Alabama; the Northwest Airlines Depot in Minneapolis, Minnesota; the, Martin-Omaha manufacturing plant, and the Hawaiian Air Depot at Hickam Field.
Although the airfield itself and the buildings to the east of the runways had been built on Henry Ford's personal property, it is unclear how the parcels across the county line that became the site of the bomber plant were assembled. In any event, Henry Ford (who, although technically retired from Ford Motor operations until Edsel's death from ungulant fever in 1943, still held a say in company affairs) had insisted on building the factory without government financing. Instead, the company built the factory, and sold it to the Reconstruction Finance Corporation's Defense Plant Corporation (RFC-DPC), which then leased it back to Ford for the duration of the war. The land which held the airfield was transferred from Henry Ford's control to that of the company in July 1944, and sold to the RFC-DPC shortly thereafter.
Willow Run as Detroit's commercial airport
Between 1946 and 1947, passenger airlines serving Detroit moved from Detroit City Airport on the city's crowded east side, to Willow Run; shortly thereafter, Wayne County officials began expanding Detroit-Wayne Major Airport at Romulus, which was 10 miles closer to Detroit than Willow Run.
Willow Run's relative isolation encouraged new approaches to passenger transportation to and from airports; at Willow Run in 1946, Warren Avis founded Avis Airlines Rent a Car Systems, the first rental car operation at an airport.
The RFC sold the airport to the University of Michigan in 1947 for $1.00. The terms of the sale required that the university operate the airport as a research facility, and the Michigan Aeronautical Research Center (later renamed Willow Run Research Center) took over some of the airport's buildings that were not needed for commercial aviation operations. For a time, the university housed some of its students in the apartments previously used by plant workers. Many of the buildings at the airport were used by University of Michigan physicists and engineers in research for national defense, including early work in antiballistic missile defense and remote sensing, at a facility which would become the Environmental Research Institute of Michigan (ERIM) after separating from the university in 1972.
At about the same time it sold the airfield, the RFC leased (and later sold) the bomber plant to the Kaiser-Frazer automobile company; the factory eventually became owned by General Motors. The last GM operations at Willow Run ended in 2010, and that property is planned for redevelopment after 2013 by its owner the RACER Trust.
For the later history of manufacturing operations at Willow Run, see the Willow Run article for the immediate postwar years under Kaiser, and the Willow Run Transmission article for the bomber plant's use by GM's Powertrain Division. Willow Run Assembly discusses a GM plant built to the south of the bomber plant, which operated from 1959 to 1992.
Decline of Willow Run
Almost all of Detroit's scheduled airline flights used Willow Run until 1958, when the coming of the Jet Age drove traffic to the Romulus airfield, which had that year been renamed Detroit Metropolitan Wayne County Airport (the name it bears to this day), and offered carriers the promise of more efficient and modern operations, with a brand-new terminal designed for the new aircraft, a newly-expanded runway configuration and state-of-the-art approach controls that made it the first inland airport in the country certified for commercial jet operations.
In 1956 there were seven commercial passenger carriers operating out of Willow Run. The April 1957 Official Airline Guide shows 68 weekday departures on Capital, 45 on American, 23 on Eastern, 17 on Northwest Orient, 14 on United, 13 on North Central, 13 on TWA, 8 on Delta, 5 on Allegheny and 3 on Mohawk. American's only westward non-stops were to Chicago; United had a nonstop DC-7 to Los Angeles; come summer TWA would resume its weekly two-stop Constellation flight to Paris, via Gander in Newfoundland and Shannon in Ireland. At this time, only BOAC and Pan Am flew out of Detroit-Wayne Major.
United was the last carrier of those to use Willow Run, moving its remaining Detroit operations in 1967 to Metro Airport. USA Jet, a charter airline, has brought commercial air service back to Willow-Run, using DC-9 and MD-82 type airplanes.
United States Air Force use
In 1951, the United States Air Force exercised a right of return to Willow Run and established Willow Run Air Force Station to the east of the airport runway (approximate coordinates ). On 7 April 1952 the site became operational with the establishment of Headquarters, 30th Air Division at the site, which was designated P-23 by ADC. In addition to the headquarters facility, Air Defense Command established a Manual Air-Defense Control Center (ADCC) at Willow Run AFS, for the tracking and control of aircraft as part of ADC's mission in the United States. Willow Run AFS operated until April 1959, when the 30th AD was reassigned to Truax Field, Wisconsin. The facility was then sold to the University of Michigan. Many of the former Air Force buildings still exist on the site and are used by various organizations.
The airport today
In 1977, the University of Michigan sold the airport to Wayne County for $1.00. The county transferred its airport operations, encompassing both Willow Run and Detroit Metro, in 2004 to the Wayne County Airport Authority, which manages both airports to this day.
The Yankee Air Museum opened on the airport grounds in 1981. A fire in October 2004 destroyed the museum's building and most of its artifacts. The static display aircraft, including a B-52 Stratofortress and other aircraft too large for display inside the hangar, were undamaged. In 2005 the museum moved to the other side of the airport where they are rebuilding their displays and gathering more World War II memorabilia. In 2013, reports emerged of negotiations between the museum and the RACER Trust that would see the museum into a section of the former bomber plant. The Yankee Air Museum also hosts semi-annual airshows over Willow Run featuring the Blue Angels.
Between July and September 2009, what was Runway 9R/27L along the southern edge of the airfield was converted to Taxiway H. This allowed the redesign of the southwest end of Runway 5R to reduce the possibility of encroachment by taxiing aircraft.
In 2011, Michigan State University planted 3 acres (1.2 ha) of canola and mustard seed on airport property to generate biofuels for aircraft use. The airport has 1,700 acres (690 ha) available for future crop production.
