I hate to think that we may be out there seven to ten years out and dependent on the Russians for our journey into space.

I was sold on flying as soon as I had a taste for it.

We (the DOE) are poisoning our people in the name of national security.

Too many people, when they get old, think that they have to live by the calendar.

On K-12 education America has gone down, down, down compared to the other nations. It doesn't mean that we have gotten dumber. It just means that we have not advanced as fast in those areas as other nations have done, and we're way down right now.

There are times when you devote yourself to a higher cause than personal safety.

I think we're a long ways from really putting colonies of people out there who would live their whole lives out there in space. I don't see that happening for quite some time.
