Never accept your limitations - because there are NO limitations.

I don't like to rate myself; others can do that. I've spoken with a number of young people who weren't even born in 1969, when the first moon landing was made. They've witnessed the first person to fly at faster than speed of the sound without propulsion. These kids are happy to have had such a momentous event in their lifetime.

People are fascinated about the world above them because it seems so out-of-reach.

One of the most exciting moments was standing out on top of the world, 30 seconds before stepping off.

Aviation - and space travel, in particular - have always been especially captivating.

That spin became so violent, it was hard to know how to get out of it. I was able to get it under control and break the speed of sound...I could feel myself break the speed of sound. I could feel the air building up and then I hit it.

The only thing you want is to come back alive.
