I think a mentor gets a lot of satisfaction in a couple of ways. They're doing something constructive, so they feel good about that. And when they see the results of this, with the young people they're working with, it's very, very rewarding.

I still love to fly and I'll never get over that.

Liftoff is very, very gentle, contrary to what most people think.

We're going to go to the moon. We're going to go on to Mars. We're going to set up a base on the moon. OK, but no money to pay for it, nothing in the budget for it. And so the decision made at that time was to cancel the whole shuttle program to save money, which I think was very, very short sighted.
