Of course I was delighted the flight was over, but I still had to worry about cleaning up inside the cabin, I had to worry about the hatch, how to get in the sling, and so on.

The rocket had worked perfectly, and all I had to do was survive the reentry forces. You do it all, in a flight like that, in a rather short period of time, just 16 minutes as a matter of fact.

Then there was the challenge to keep doing better and better, to fly the best test flight that anybody had ever flown. That led to my being recognized as one of the more experienced test pilots, and that led to the astronaut business.

The last flight I was on, the hatch wouldn't open. I was the commander of that flight. I was treated like any manager on the ground. I was asked my ideas by top-level NASA managers.

You've done it in the simulator so many times, you don't have a real sense of being excited when the flight is going on. You're excited before, but as soon as the liftoff occurs, you are busy doing what you have to do.

We wanted to be in great shape, we wanted to be able to cope with zero gravity, we wanted to be able to cope with accelerations and decelerations and so on. So all of us trained so that we were probably in the best physical condition we had ever been in up until that point.
