@argv_minus_one The saucer section isn't supposed to land on any planet, nor is the rest of it. They are serviced in space. Probably wouldn't be a design feature. Tough luck, should it land.
However, now I'm wondering how an elevator might work from reversed artificial gravity to the deck. I suppose the tube it is in could maintain the artificial gravity, then rotate the elevator compartment at the end, but that was never addressed, was it?
Hm.
