I was motivated to improve the U.S. strategy of going back to the moon in 1985. That's a long time ago. Going back to the moon would be a great achievement for tourism adventure flights.

To move forward, what's required is a unified space agenda based on exploration, science, development, commerce, and security.

Let's not spend resources that we don't need to be sending astronauts back to the moon. Let's not spend expensive resources on bringing people who have reached Mars back again. Prepare them to become a growing colony.

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.

We feel that this stands as a symbol of the insatiable curiosity of all mankind to explore the unknown.

My favourite thing to do on this planet is to scuba dive.

Sending a couple of guys to the Moon and bringing them back safely? That's a stunt! That's not historic.
