Story Musgrave: Space is a calling of mine, it struck like an epiphany. That occurred when NASA expressed an interest in flying people who were other than military test pilots. And when I was off in the Marine Corps in Korea, I had not graduated from high school yet, and so I could not fly. And so, I was not a military test pilot, but as soon as NASA expressed an interest in flying scientists and people who were not military test pilots, that was an epiphany that just came like a stroke of lightning. And, I saw that everything I had ever done in life could be used in that endeavor. It just fit and it felt just right.
