Apollo 7 Crew: Don F. Eisele, Walter M. Schirra, R. Walter Cunningham
Apollo 7, launched October 11, 1968, was the first manned mission of the Apollo program and the first time the U.S. sent men into space since Gemini XII in 1966. The fire that killed Apollo 1's crew put the space program on hold for almost two years.
Shortly after launch, Commander Schirra began to experience symptoms of a cold. In zero-gravity, it is much harder to expel mucous from the sinuses. As with virtually everyone else, being sick puts us in a grouchy mood, and that's what happened to Schirra. Then his foul mood brought the rest of the crew down and they started snipping at Mission Control. Although the mission was considered a success, it has been since dubbed "mutiny in space" because of the tensions between the crew and Mission Control.
