Timing has always been a key element in my life. I have been blessed to have been in the right place at the right time.

I expected the unexpected and went [on the Moon] with an open mind. I think the visual scene was described by my words on first landing - "magnificent desolation." Magnificent for the achievement of being there, and desolate for the eons of lifelessness.

I want to keep on the move, keep stimulated and challenged.

I've been to the Titanic in a yellow submarine and the North Pole in a Russian nuclear ice breaker.

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.

I remember it was hard to believe that I was taking a step onto the lunar surface.

I didn't start skiing until I was 50. My wife Lois taught me how to ski. I'm proficiently conservative.
