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.

That whole day [ of the space flight] is very vividly impressed on my memory because it was such a new experience. We hadn't done that before. And then I've recalled it so often since then I think that it's a - it's remained very vivid over the past 50 years, seems to me like about a week or two instead of 50 years.

The moment of twilight is simply beautiful.

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.

Just because I'm 77 doesn't mean I don't have a dream.

I don't like the way the whole thing has developed. And I just hope that we develop our own transportation system, both spacecraft and new boosters, as soon as possible. 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.

That was a real fireball.
