What's going on in mechanical? Given this is based on the show that's painfully wrong. The generator seems to be in the wrong place AND the drill is upside down and an alien shuttle.

The scale of the silo is pretty cool to see, though.

Yeah, there's a lot here that is inaccurate to both the tv show and the books. There are no walls around the stairs at most levels. It also seems to depict silo 17 as mostly flooded, when it was only the lower 30 floors.
