1941
When the United States becomes involved in World War II in 1941, the federal government purchases a site for construction of an army air base and test field for B-24 “Liberator” bombers. The site adjoins approximately 320 acres of land owned by Henry Ford and located on the banks of a stream called “Willow Run.” The federal government selects Henry Ford and the Ford Motor Company to build what would become the largest bomber plant in the world.
1942
Willow Run Airport construction, including Hangar 1, is completed. The U.S. government invests an estimated $15 million.
1945
By 1945, the airlines have outgrown the available space at Detroit City Airport and the airport is not large enough to accommodate the four-engine transport-type aircraft airlines are purchasing. As a result, airline operations are transferred to the larger Willow Run Airport.

1950s
Some commercial air traffic begins moving from Willow Run to Detroit-Wayne Major Airport. In 1953, The Willow Run Bomber Plant is eventually sold to General Motors to build transmissions. As airplanes of the jet age require even larger airfield and terminal facilities, airline operations begin to transfer once again. In October 1958, American and Allegheny Airlines move their scheduled passenger operations from Willow Run to the newly completed terminal facilities at Detroit Metropolitan Wayne County Airport (DTW). The airlines join Pan American World Airways, which began service at DTW in 1952.
1960s
By June 1966, the final commercial air carriers at Willow Run Airport—United Lake Central, North Central and Mohawk Airlines—move their service from Willow Run Airport to Detroit Metropolitan Airport. This change eventually solidifies Willow Run’s important role as a reliever airport, and brings the number of scheduled passenger airlines at DTW to 13.
