''Hangar 18'' is about a cover-up following a UFO incident aboard the Space Shuttle. A satellite, just launched from the orbiter, collides with an unidentified object which, after being spotted on radar moving at great speeds, had positioned itself just over the shuttle. The collision kills an astronaut in the launch bay. The events are witnessed by Bancroft and Price, the astronauts aboard. After returning to Earth, the two are immediately stymied when they try to discuss what happened. They are told by Harry Forbes, Deputy Director of NASA, that "everything is going to be all right".
