In a big picture sense, it's more national prestige that we're risking. You know, we are proud of our space program, but as we were talking earlier, the average American doesn't think that much about it right now. So, it may seem like something we could just give up and not really worry about it, but I think it starts creeping into the national psyche. If American astronauts have to hitch rides with the Russians or other nations in the future.

The training kicked in and we quickly went through our emergency procedures, I took manual control and I got the spacecraft under control and stopped about 50 meters from the space station. So, the net effect of the failure was that we were actually turning and speeding up towards the space station when we should have been slowing down, so it was quite a dangerous situation. But we got manual control, performed the first manual docking to the station at night. The training pays off. It was just automatic. We had our books out already, we went right to the right procedures and executed them.

The only two countries who will be able to launch people into space will be Russia and China. I've seen the Russian technology up close and I've had a chance to look at some of the Chinese technology. It's a very high level. They have good hardware and what China lacks is operational experience. But as they gain more experience, as they fly more missions, they'll catch up quickly. The U.S. does face the possibility of losing the lead in human space flight during this period of what we call the gap.

I think it's good to have competition. Now we have a third country that can launch astronauts, so it's good for all of us. It makes us a little bit more competitive and wanting to be the leader.

When Russians were having troubles, the Space Shuttle supported the Space Station Mir bringing up much needed supplies and replacements, critical spares, really. That they were able to keep their space station going for much longer than they would have without us. So, I think that shows the value of international cooperation.

I actually had four space flights altogether, three times on shuttles. My second flight was really unique for me because I was going back into space, first of all. The first one was like an appetizer at a nice dinner. You know, you want to go up and you want more. So, the second time I got into space, it was neat because I got to actually do two space walks.

I loved flying as much as I thought I would and continue to fly aircraft.
