Monolithic domes need not be spheres - they can be oblate spheroids
therefore not as tall.

True, but to give strength to the roof, (the curve is needed) in a large
enough building to house 8 airplanes, it will still be high enough to put a
second story in, I would think. The truss type floor could be supported by
the walls of the dome and a load bearing structure in the middle.
Otherwise, the truss would have to be wicked strong, and that means tall.

Actually, the floor doesn't rotate, just a spider frame made of 6"
channels.

Right, but there can not be any permenant structures in the arc of the
moving channels, or the channels could not move past them.

There could be a structure in the middle, with the frames rotating around
it, much like a "merry-go-round."
