SPACE SCHOOL

摘要

Sending people to space has always involved a frank assessment of their defects, and in the early days, it was a matter of finding people without any. First it was fighter pilots-calm in a crisis, physically perfect, unquestioning in their execution of mission control's instructions. Then, as it became clear that space was more than a military objective, space agencies began to train scientists for flight, placing otherwise reasonable researchers into fighter jets and swimming pools and screening them relentlessly for defects of vision, circulation, or character.
