Unlike the British Royal Air Force (RAF), which eventually shifted to night bombing, the Americans believed the B-17’s heavy defensive armament and the secret Norden bombsight allowed for high-altitude, precision daylight strikes.

This strategy was tested during harrowing missions like "Black Thursday"—the second raid on the ball-bearing factories in Schweinfurt. Without long-range fighter escorts like the P-51 Mustang, B-17 formations faced devastating losses from German Luftwaffe interceptors. Legendary Durability Beyond the Bombing Run : After 1945, the
