Production. B-24E (Liberator) bombers at Willow Run. The half-hour lunch period at Ford's big Willow Run plant is usually spent near one of the sections of the B-24E (Liberator) bombers. 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
