That US lunar module does not appear to be to code. It wouldn't pass mustard in Maryland. I can't see a handrail on the stairs for starters and the distinct lack of a main stack looks suspect. All those B-vents sloping down has got to be a no-no. What part of the Uniform Plumbing Code did they not understand? Or is this on a well?
Just because you're rushing to get to the moon does not mean you can cut corners, and they clearly have been cut here. Don't get me started on those trip hazards.
Any time you see someone wearing a suit to breathe, you can count your bottom dollar you are going to find violations.
As Kennedy put it, "We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win but it won't be code compliant, sorry. No-one really follows the codes anyway and we don't really need them round here. etc. etc. "
