And then, when I thought about joining the Air Force, flying seemed like a natural extension of the motorcycling experience. You're going faster, higher. You're operating a machine that's a lot more powerful than you are.

I consider myself to be very fortunate in my career, my timing has worked out.

Well, for me it really wasn't a case of deciding to be an astronaut.

And, all these things need to be coordinated; so we all need to work together, have timers going and everything so we're all coordinated and get this piece of orchestration done.

I see it as one of my jobs to make sure that, it sounds ridiculous, but to make sure the folks are eating, make sure folks are getting enough fluids, make sure folks are, you know, comfortable in the orbiter.

So, I decided that whatever I was, wanted to do with my life, it would have to do, it would have to have something to do with the exploration and doing new things.

And, I wouldn't consider myself to be a natural pilot; I've had to work at it.
