Willow Run Airport, just east of Ypsilanti, was originally farmland purchased by Henry Ford to build a plant to support the building of the B-24-E during WWII. The ground was broken for the project in April of 1941.
Willow Run was the first manufacturing site to employ women on the assembly line. At one point Willow Run employed 15, 412 women, making up 39% of their work force. These women worked every job that they were physically capable of doing, along with equal pay to men. The women generally worked nine-hour days, with a 30-minute lunch and a few 15-minute breaks. 
The famous B-24-E contains 300,000 rivets. These women could produce a B-24-E in 59 minutes, the fastest of any plant in the nation. By the end of the war the Willow Run Plant had produced over 8,500 B-24-E Bombers.
