The B-17 Flying Fortress was by far the most popular and most successful bomber built and flown during WWII. It was a four engine heavy bomber aircraft. Manufactured by Boeing, it initially went into service in 1937 and well over 12,000 of them were built but today only a few of them are in flying condition.
The B-17 Flying Fortress was used primarily as a daylight bomber during WWII over German military targets. It was particularly known for its ability to withstand severe battle damage and yet still be able to bring its crew back to the home base safe. There are numerous counts and photos of badly damaged B-17s with wing or control surface sections missing that yet their crews were able to fly them back home hundreds of miles and land them safely sparing their lives. The "Memphis Belle" was one of those B-17s that was able to fly 25 missions successfully despite several close calls and was returned back to the States to give tours to boost war morale. A famous motion picture movie was made in the 1980s depicting the life of the "Memphis Belle" and its crew.
Although lacking the performance, range and bomb loading ability of the B-24 Liberator the B-17 Flying Fortress was the most used bomber during WWII dropping over one third of all bombs over Germany.
They were several variants of the B-17 Flying Fortress built in large numbers. B-17E, B-17F, B-17G (most produced model), and several other variants in smaller quantities.
