What we are doing is unheard of in the history of recovery operations. I searched for space shuttle debris for 17 days, but I've never searched house to house in a city this size.

If we're going to complete the space station, we're going to need the shuttle. It's going to take a lot of resources.

The space shuttle is a better and safer rocket than it was before the Challenger accident.

I slept just floating in the middle of the flight deck, the upper deck of the space shuttle.

On a standard space shuttle crew, two of the astronauts have a test pilot background - the commander and the pilot.

I would still like to go up in the space shuttle. It's appalling that the accident happened, but it was an accident and obviously if I knew there was any risk, I'd be foolish to do it. I'd love to stand outside the Earth and look at it. Extraordinary feeling that, something that we've been tied to for millions of years, and a handful of people have looked at it, to be able to do that would be stunning.
