I still have my [flight] license and I can still pass a flight physical.

Because now, you know, it's going to be a number of years yet before we have our own new boosters and new spacecraft to go to our own International Space Station and proceed with all the research that we spent $100 billion putting up there to give us that research capability for the future for people right here on Earth.

There had been a number of failures but we weren't going out to ride a failure. And we felt they'd corrected all the difficulties with the boosters before that time and the launch problems. And so we had a lot of confidence that there was going to be a successful mission. We weren't off on some suicide effort, certainly.

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

Liftoff is very, very gentle, contrary to what most people think. Because you remember, the weight of the booster - the amount of thrust on the engine is just barely enough to get the booster underway. And so it's a very gentle liftoff, contrary to what most people think when they see all the fire and smoke of launch.

I suppose the one quality in an astronaut more powerful than any other is curiosity. They have to get some place nobody's ever been.

I don't know what you could say about a day in which you have seen four beautiful sunsets.
