In the early days of the shuttle program, NASA wasnt sure how crews of five, six, and seven people would fare in the limited space of the orbiter. Here the crew of STS-51A, who flew in November 1984, give a tour of the upper and lower decks. Onboard were Rick Hauck, Dave Walker, Joe Allen, Anna Fisher, and Dale Gardner. Allen, who had been an astronaut since 1967 but hadnt flown until 1982, was making his second flight. (3:54)
