Production. B-24E (Liberator) bombers at Willow Run. A new B-24E (Liberator) bomber, just off the assembly line at Ford's big Willow Run plant, gets a last-minute inspection before taking off on its test flights. 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
