Production. B-24E (Liberator) bombers at Willow Run. Looking down one of the two final assembly lines for B-24E (Liberator) bombers at Ford’s big Willow Run plant. Guns and wing tips have not yet been added to the planes in the foreground. The Liberator is capable of operation at high altitudes and over great ranges on precision bombing missions. It has proved itself an excellent performer in the Pacific, in Northern Africa, Europe and the Aleutians. Ford’s Willow Run Plant, Michigan.
