Test pilots have a litmus test for evaluating problems. When something goes wrong, they ask, "Is this thing still flying?" If the answer is yes, then there's no immediate danger, no need to overreact.

Frequently on the lunar surface I said to myself, 'This is the Moon, that is the Earth. I'm really here, I'm really here!'

Eventually there are going to be cities in space.

It seems farther away now because there are no rockets getting there. Nobody is going.

We knew it was going to be difficult to get to the moon. We didn't know how difficult.

I can remember walking on the moon.

I feel like there's too many paintings left unpainted that I just don't want to take the time away.
