thinner than a pop can

I don't think that's quite true.

A quick web search says the skin of the LEM pressure vessel was, at its
thinnest, 12/1000 of an inch thick. One source I found for aluminum
(pop) can wall thickness stated 5/1000 of an inch thick, which is less
than half the thickness of the LEM's skin.
