When Lindbergh was introduced to the king of England after his 1927 flight, the king asked “How did you pee?”
I don’t see that this is a dumb question or a rude one. Arrangements for bodily functions is one of the problems engineers have to solve when planning space missions. The question wasn’t meant personally, and it is hard to believe that an astronaut brave enough to go up in space ship is too shy to answer.
Do you know Lindy’s answer? I hope it was something along the lines of “Just like you do. Or maybe not. Tell me how a king pees and I’ll tell you if I did the same.”
