The Boeing 17 Flying Fortress was a heavy bomber, that was used by the United States Strategic Air Force during World War II. It first flew in 1935, and was introduced in 1938. It had a shorter range, and a smaller bomb load, than its sister bomber the B-24 Liberator, but it had more defensive armament. It dropped large amounts of bombs during air raids against Germany, such as the raid on Dresden. The B-17 was also used in the Pacific, including the Battle of Midway. The Flying Fortress had its name for a good reason, it could survive the hits and was able to fly while under enemy fire. The B-17 was a heavy bomber plane that carried 2 tons of bombs. The reason why few B-17's survived WWII was because lack of escort by allied fighters and enemy fire. Later in WWII, the U.S. increased escort fighters for the bombers giving more protection. The escort fights flew until the end of WWII.
