If you want something that's going to provide you with a lot of challenges and a variety of different things to do, then you really can't beat a place like the Air Force. I don't mean this to sound like a recruiting pitch. But it's been a lot of fun.

It looks like the future's really bright.

Like most kids growing up, I had a very wide interest. I was interested in everything. I tried to take advantage of everything, from the sciences to music to writing to literature.

Science was something that really caught my attention. It was something I really could sink my teeth into.

When you launch in a rocket, you're not really flying that rocket. You're just sort of hanging on.

As you look back at your life, there are just a million different things that have happened, just in the right way, to allow you to make your dreams come true. And you know, someone has all that under control.

I was always fascinated by science-fiction shows, shows like 'Star Trek' and 'Lost in Space.'
