Enola Gay was the name of the airplane that was used to drop the atomic bomb on Hiroshima on August 6, 1945. This was a B-29 Superfortress bomber. The airplane was named after the mother of the pilot. His name was Paul Tibbets and he was a colonel at the time of the bombing. The name was given to the airplane only the day before the bombing of Hiroshima when Tibbets was given command of the mission.
Enola Gay was one of 15 B-29s that was made especially to be used for carrying atomic bombs. For this reason, it did not have as much armor as a regular B-29 nor did it have gun turrets.
it was a plane that was used in ww2 to drop the atomic bombs on hiroshima and nagasaki :)
