Before you jump to conclusions, the performance of the STS-2 team is not the reason NASA informally banned subsequent all-rookie spacecraft lineups. While Engle and Truly did violate NASA orders during the mission, their performance was both laudable and daring. And if that seems counter-intuitive, wait until you realize that one of these two NASA rookies already earned his US astronaut wings before he ever entered the space program.
How did NASA send up an all-rookie crew on STS-2 if one of the crew members was already an astronaut?
