Whether you are an astronomer or a life scientist, geophysicist, or a pilot, you've got to be there because you believe you are good in your field, and you can contribute, not because you are going to get a lot of fame or whatever when you get back.
Then there was the challenge to keep doing better and better, to fly the best test flight that anybody had ever flown. That led to my being recognized as one of the more experienced test pilots, and that led to the astronaut business.
You know, being a test pilot isn't always the healthiest business in the world.
The pilot looked at his cues of attitude and speed and orientation and so on and responded as he would from the same cues in an airplane, but there was no way it flew the same. The simulators had showed us that.
But when I was selected, after my very first tour of squadron duty, to become one of the youngest candidates for the test pilot school, I began to realize, maybe you are a little bit better.
