"Then there was the challenge to keep doing better and better, to fly the best test flight that anybo..." — 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 first plane ride was in a homemade glider my buddy and I built. Unfortunately we didn't get more than four feet off the ground, because it crashed.

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.
