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

If you increase the number of rockets you build and you buy, then it's the scale of the economy, the price is going to come down. It may not come down in order of magnitude, but if several commercial ventures start being successful and there becomes a bigger market for these rockets, the price will naturally come down a bit. That's why I think Excalibur Almaz, we're a little bit unique in that we don't look at our so-called competition with disdain, we want them to succeed and it needs to have more than one player. Even if we are successful, we couldn't handle the entire market ourselves.

On the mission I brought a flag from China, I brought the stone sculpture from Hong Kong, and I brought a scroll from Taiwan. And what I wanted to do is, because as I was going up and I am this Chinese-American, I wanted to represent Chinese people from the major population centers around the world where there are a lot of Chinese people. And so, I wanted to bring something from each of those places and so it really wasn't a political thing and I hope people saw it that way. I was born here, I was raised in the U.S., and I'm an American first, but also very proud of my heritage.

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.

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 ultrasound that has application not only in space for a long mission or for a mission to the Moon or Mars, but also in remote areas on the Earth. Not even just - I'm not even talking about expeditions like to the Antarctic, but just a remote area, a small town somewhere. The local doctor is not going to know everything, and so if that person can link in with a diagnostic ultrasound to the hospital in New York City through the internet, then they can do a very quick diagnosis of something that's wrong with someone that's in this remote area.

That was in 1994, July, 1994, and I can remember that like it was yesterday too because it was the culmination of a childhood dream to finally be laying on the launch pad inside a space shuttle and getting ready to be launched into space. The impression of going into a space shuttle is that it looks like a brand new simulator. We spend so many hours inside a simulator that everything is very familiar. Every switch, the seats, the way things work, but the vehicle, the actual spacecraft looks brand new because it hasn't been used nearly as much as the simulators.
