The flight experience itself is incredible. It's addictive. It's transcendent. It is a view of the grand plan of all things that is simply unforgettable.

At no time, when the astronauts were in space were they alone, there was a constant surveillance by UFOs.

I liked wrestling a lot better than boxing. I remember thinking at that time that wrestling was a pure demonstration of strength, which I was interested in, while boxing was just hitting somebody or getting hit, which didn't appeal to me. But a demonstration of strength was okay, so I chose wrestling.

Pioneering in space was something I would willingly give my life for.

This planet is not terra firma. It is a delicate flower and it must be cared for. It's lonely. It's small. It's isolated, and there is no resupply. And we are mistreating it.
