The B-52B Stratofortress on display at Wings Over the Rockies was the seventh B-52 built and was originally created as an RB-52B for long-range reconnaissance operations. The Air Force used it for avionics testing before being converting it into a bomber. Then it served with the 93rd Bomb Wing, where it served during the Cuban Missile Crisis. In 1966, it came to Lowry Air Force Base as a training airframe for munitions loading instruction. The B-52B is on loan from the National Museum of the US Air Force. (from the Museum's website)
