Plot
Sergeant Deadhead is a bumbling soldier who is sent to the guardhouse for blowing up a model rocket on the parade ground of the air base where he is stationed. His fiancée, Airman Lucy Turner despairs of ever marrying him because of him being constantly disciplined for his antics. She is worried that she will have to marry him while he is in the guardhouse.
Together with Private McEvoy, Sergeant Deadhead escapes from the guardhouse. Private McEvoy decides to break back in, but Sergeant Deadhead hides in a nearby space rocket, not knowing it is set to blast off with a chimpanzee aboard. He falls asleep in the rocket's control room and is accidentally blasted into space, together with the chimpanzee.
When Sergeant Deadhead is discovered to be aboard the rocket, General Fogg decides to spin the facts and say that Sergeant Deadhead volunteered for the mission. He and Navy Captain Weiskopf also decide that Sergeant Deadhead and Airman Turner will have a well publicized wedding on the air base when Sergeant Deadhead returns to earth.
