Okay this was tried a little time ago and I think Jay asked a question no-one could answer so it died. But being one to beat a dead horse....
Okay rules. Answer the previous question (preferably with a link) and if it is called correct by the OP of the question, or seconded as correct by one of our resident Apollo nuts (Jay and Bob) then you post the next question and so on. Okay?
To start the ball rolling.
On leaving the moon each mission jetisoned various parts of their suit and keep other parts for historical purposes. Which of the parts that Apollo 11 returned with did Buzz later say he wished they hadn't saved, and what was the part of the suit he wishes they had brought back instead?
