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 worked for some very good people who have helped me along the way and actually enabled me to have the opportunity to be selected to join the Astronaut Corps.

Now you're coming back to Earth, and things are getting more and more dynamic.

And, that's what I truly believe that we're doing when we're advancing scientific knowledge is we're someday making the world better. Not only for our children, but for all people after that.

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.

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.

There's been a tremendous amount of work that's been done that you can't see in Columbia.
