I shot down two airplanes in Korea, so I wasn't a slouch.

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.

Just as Mars - a desert planet - gives us insights into global climate change on Earth, the promise awaits for bringing back to life portions of the Red Planet through the application of Earth Science to its similar chemistry, possibly reawakening its life-bearing potential.

When we set out to land people on the surface of Mars, I think we should as a nation, as a world, commit ourselves to supporting a growing settlement and colonization there. To visit a few times and then withdraw would be an unforgivable waste of resources.

Is the destiny of the human species to sit back and play with our mouse and computer and imagine, fantasize?

Like actors and writers who are on and off again in terms of employment, I had a very unstructured life.

Climate has been changing for billions of years.
