Bombers Over Manhattan, 1940

View of northeast of the Lower Manhattan Skyline in 1940 as B-17 Bombers fly over the city.  Developed by Boeing in the late 1930s, the B-17 Flying Fortress was a strategic weapon for the Allies in World War II.  A high-flying four-engine heavy bomber, the B-17 dropped more bombs than any other U.S. aircraft during World War II.  Over 12,000 were manufactured before production ceased in 1945.  The Brooklyn and Manhattan Bridges can be seen in the background along with some Lower Manhattan skyscrapers.
