Selection of crews is always been somewhat of a mystery.
This vehicle is performing like a champ. I've got a super spaceship under me.
Looking down at the Earth, you started to pick up a sense of speed much more than I had noticed on orbit.
When you work really hard for something for a long time it's almost impossible to believe that it's coming true. 
You're going very fast when you're on orbit, going around the world once every hour and a half.
Having the opportunity to fly the first flight of something like a space shuttle was the ultimate test flight. 
We were only on orbit a little over two days, so we had no adverse effects from being weightless.
The nature of the shuttle was, we couldn't put a crew escape system in it.
