Looking down at the Earth, you started to pick up a sense of speed much more than I had noticed on orbit.

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...

The powered flight took a total of about eight and a half minutes. It seemed to me it had gone by in a lash. We had gone from sitting still on the launch pad at the Kennedy Space Center to traveling at 17,500 miles an hour in that eight and a half minutes. It is still mind-boggling to me. I recall making some statement on the air-to-ground radio for the benefit of my fellow astronauts, who had also been in the program a long time, that it was well worth the wait.

We were only on orbit a little over two days so we had no adverse effects from being weightless...

If you want to go into space first time on a new vehicle that's never been flown, you want to go with a pro.

The nature of the shuttle was, we couldn't put a crew escape system in it.

You're going very fast when you're on orbit, going around the world once every hour and a half.
