The next oldest astronaut is Story Musgrave at 61
I’ve met him, y’know. A gentleman, a proper legend and true genius; because he was bored one day he became a practising brain surgeon as a hobby in his time off.
He told a tale of his last shuttle flight, on re-entry you have to be strapped in on pain of court marshal or some such. Story figured he wanted a souvenir so fished out a contraband camera and hopped up to take some photos out of the back window. NASA were all, eh, it’s just Story, let him get on with it.
I’ve modelled a career on that anecdote, easier to get forgiveness than permission. (-:
