Back in 1969 or 1970, NASA brought an exhibit to the California group, Foundation For The Junior Blind. I was able to visit the exhibit and they had one of the original Mercury capsules on display. You could see the damage done to the heat shield and paint during re-entry. I remember peering into the tiny door... the inside smelled!
The NASA person said that the astronaut would get in, settle himself into the seat and then the engineers and technicians would *re-assemble* the control panels and equipment around him! There was no way an astronaut could get *out* again until splash-down when the personnel of the recovery ship would unbolt all that stuff and remove it. Then the guy had to be lifted out.
We got to see (and touch) the capsule, the space suits (they had two of them) and get a sample of this *incredible* space-age fastening stuff! It was a little cloth strip with sort of wooly stuff on one side and another strip with coarser wiry stuff on the other... I think it was called... Vel-Cro?
Man I hung onto that little strip for YEARS! We blind kids were among the very first civilians to get samples of the new material.
