I have been a fan of Dexter since the pilot. Once I got the audition I just squealed, and you would have thought I just won 45 million dollars.

I flew fighters for the Navy in San Diego for three years, went and did my post-graduate education, and then I was a test pilot in Patuxent River, Maryland, for a few years. I was back in the fleet in the Navy when I was selected to come back here to NASA to become an astronaut.

I was influenced by many, many different people in my student years, and I was always, I guess, immersed in a Navy environment, and so, obviously, that had a big impact when I decided what I wanted to do was go and be a Navy pilot. I was very familiar with the Navy community and felt very comfortable with it.

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.

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.

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.
