Now think of something 10 times larger.

I actually did some of those computations on Apollohoax for a large hangar-sized vacuum chamber. I don't remember the exact loads and moments, but I remember they were surprising enough to make me go back and see if I could find my mistake because I was sure it couldn't be that much.

It's always fun to hear the hoax believers go on and on about the miraculous structural technology, materials science, and anti-gravity generators NASA must have invented in order to produce a suitable environment for faking the EVA film and video. Then it's fun to ask why, with all that miraculous know-now, they couldn't get past a little radiation.
