On August 6, 1945 the United States dropped an atomic bomb on the city of Hiroshima, Japan. It was the first time a nuclear weapon had been used in warfare. There were three strike planes that flew over Hiroshima that day: the Enola Gay which carried the bomb, and two escort planes, the Great Artiste and the Necessary Evil. Russell Gackenbach was a Second Lieutenant and a navigator on the mission. Today, he is the only surviving crew member from those three planes.
