Willow Run Airport

Willow Run Airport is an airport in Van Buren Charter Township and Ypsilanti Charter Township, near Ypsilanti, Michigan, United States, that serves freight, corporate, and general aviation. Due to its very close proximity to Detroit Metropolitan Airport, no major airlines schedule passenger flights to or from Willow Run. It is included in the Federal Aviation Administration National Plan of Integrated Airport Systems for 2017–2021, in which it is categorized as a national reliever airport facility.

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 June 1945; Willow Run produced more Liberators than either plant owned by the plane's designer, Consolidated Aircraft.
