Wasn't the door out of the lander too small for the astronauts to get in and out with their backpacks on?
This is a 'fact' that's often quoted, but has never actually been proved. I think Ralph Rene came up with this one, originally by looking at the door and guessing it was too small. (There was something to do with crawling under a kitchen table as a scientific experiment.) In Ralph's world this is conclusive enough to make it a fact. There is really nothing else that can be said about this until some actual, real evidence is put forward to show how it was too small.
