U.S. bombers blast German port. A U.S. Flying Fortress (foreground) drops a stick of bombs, as the largest number of planes ever sent out by the Eighth U.S. Army Air Force bomb U-boat yards, docks and factories at the German port of Bremen on Nov. 26, 1943. Plumes of vapor trail the Fortresses and Liberator heavy bombers, which together with escorting Thunderbolts and Lightnings fighter planes shot down 56 German aircraft during the daylight attack.
