Air power for the United Nations.

Air power for the United Nations. These main fuselage sections of the famous Flying Fortresses built by the thousands in the United States are part of the giant air forces built to destroy the Axis powers. These sections move forward through the factory and will soon be joined to tail sections, wings, engines, arnaments and final installations. The U.S. built more than 9,000 war planes in November, 1943, and more than 1,000 of these were huge four-motored bombers like these Flying Fortresses.
