Production. B-17F heavy bomber. Working on the roof of a B-17F (Flying Fortress) bomber swung over on its side in the Boeing plant at Seattle. A turret will be mounted over the large circular opening. The Flying Fortress, a four-engine heavy bomber capable of flying at high altitudes, has performed with great credit in the South Pacific, over Germany and elsewhere.

– Andreas Feininger, December 1942, United States, Office of War Information, Library of Congress
