"The first plane ride was in a homemade glider my buddy and I built. Unfortunately we didn't get more..." — Alan Shepard

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.

The excitement really didn't start to build until the trailer - which was carrying me, with a space suit with ventilation and all that sort of stuff - pulled up to the launch pad.

So everything turned out fine, and we were given the opportunity to go to Washington and be briefed on the project of man in space, and given the opportunity to choose whether we wanted to get involved or not.

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.
