In fact I have nightmares about having children. I want to carry a baby and feel the life within me and in my dream, I do. But every time after it's born, there's this incredible fear, this pounding pulse of fear. It's a real bad nightmare.
After the loss of Columbia a couple of years ago, I think we were reminded of the risk. All of us, though, have always known that the Space Shuttle is a very risky vehicle, much more risky than even flying airplanes in combat.
I never thought I was particularly talented, and to be honest with you, I still don't.
