Michael D. Griffin: “We have a space debris challenge. We're not going to be able to do anything in space unless we have some sort of space…”

I believe that if God had wanted us to go to Mars, he would have given us a moon to practice on.

I think we depart from that at our peril.

Had I been given the orders that my successor was given, I would have resigned because I thought... we were on the right path.

If we treated the Air Force as we do the space program, we wouldn't have any flying aircraft.
