The purpose of going to Mars is for humans to first begin to occupy, permanently, another planet in the solar system. The astronauts or pilgrims, whatever you might call them, are going to be very historically unique human beings.

I'm not in favor of just taking short-term isolated situations and depleting our resources to keep our climate just the way it is today.

As a youngster, I read of Buck Rogers and Flash Gordon. As a student, I wrote English reports on science fiction. And as a fighter pilot, I observed the selection of the Mercury astronauts. All this was fascinating, but I really didn't think I would ever be a part of it. It was only when my good friend Ed White was selected as a Gemini astronaut that I decided to join NASA as part of the Apollo program.

There are a lot of reasons for not doing something. And if humanity had come up with all the reasons for not doing something we wouldn't have spread across the Earth the way we have. There's a curiosity, and I would submit that that curiosity will put human beings on the surface of Mars.

I think the public needs to be reminded just how much inspiration and intention was given throughout the world to be bold, to send human beings to the moon in the '60s and the '70s. It's important now to bring together the nations that weren't able to do it then and help them do it. We need to move forward.

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.

Drive over to the nearest airport, and enroll in flight classes. You will experience the joy of freedom in the air above, as you study the mechanics of how this is made possible by understanding the construction, the laws of motion, the air that can provide lift when it is moved by propulsion through the air, and stay above the gravity pulling the airplane back down to earth.
