Ever since I was a little boy, I dreamed I would do something important in aviation.

If that's there, I believe that technology will probably step up to their part of it.

I fully expected that, by the end of the century, we would have achieved substantially more than we actually did.

How we use the knowledge we gain determines our progress on earth, in space or on the moon. Your library is a storehouse for mind and spirit. Use it well.

Research is creating new knowledge.

Shoot for the stars but if you happen to miss shoot for the moon instead.

Well, I think we tried very hard not to be overconfident, because when you get overconfident, that's when something snaps up and bites you.
