Meet the Other B-29 To Drop an Atomic Bomb on Japan The B-29 bomber has remained so controversial that there were protests when it was put on display at the National Air & Space Museum in Washington, DC. Here's What You Need to Remember: The Bockscar is largely forgotten even though it carried the second atomic bomb—Fat Man—which was dropped on Nagasaki days after the first bomb was dropped on Hiroshima. The Enola Gay is remembered today as being the aircraft that dropped the first atomic bomb on Japan nearly seventy-five years ago, and its infamous flight has been the subject of much debate. The aircraft’s mission has been chronicled in movies, TV shows and even a 1980s anti-war song by the British New Wave group Orchestral Manoeuvers in the Dark—although the song was as much about UK’s Prime Minister Margaret Thatcher’s decision to allow nuclear missiles to be stationed in Great Britain.
