Houston, that may have seemed like a very long final phase. The autotargeting was taking us right into a ... crater, with a large number of big boulders and rocks ... and it required ... flying manually over the rock field to find a reasonably good area.

I thought the attractions of being an astronaut were actually, not so much the Moon, but flying in a completely new medium.

Gliders, sail planes, they're wonderful flying machines. It's the closest you can come to being a bird.

All in all, for someone who was immersed in, fascinated by, and dedicated to flight, I was disappointed by the wrinkle in history that had brought me along one generation late. I had missed all the great times and adventures in flight.

We have no proof, But if we extrapolate, based on the best information we have available to us, we have to come to the conclusion that ... other life probably exists out there and perhaps in many places.

In flying, the probability of survival is inversely proportional to the angle of arrival.

It's a great thing for a man to walk on the moon. But it's a greater thing for God to walk on the earth.
