A mind concerned about danger is a clouded mind. It's paralyzing.

The way I see it, what is going to come out of the moon activities is a respect for U.S. leadership.

The energy varies with the square of the velocity, so if you need five times the velocity, that's 25 times the energy.

I'm sure the most favorite airplane in my career would still be the Sabre F86 cleft wing , which allowed me to be credited with 2 Russian-built Mig-15 destroyed during the Korean War. Where I was in 1953.

The moon I see now is the same moon I saw before. Except that before, when I looked at it, it was in anticipation of what it would be like when I got there. That's behind me now.

Over the years, I think I've matured in my spiritual evolution and development to understand a bit more than the narrow religious thinking - to move beyond that through a sort of perfection of the grandiose nature of the universe, and how perfect it is it in its sense and how satisfied we should all be in our place in that.

You can tell I'm not too bashful about some of my feelings.
