Selection of crews is always been somewhat of a mystery.
You're going very fast when you're on orbit, going around the world once every hour and a half.
The nature of the shuttle was, we couldn't put a crew escape system in it.
I was selected to be an astronaut on a military program called the Manned Orbiting Laboratory back in '67 and that program got cancelled in '69 and NASA ended up taking half of us...
This vehicle is performing like a champ. I've got a super spaceship under me.
Living inside the shuttle was a little like camping out. We ended up sleeping in our seats. You had to pay attention to housekeeping, not get things too dirty.
