And just to clarify.. it's not that you have the ride start, the banshee jumps and you drop and then the system slowly moves you back up in place.
It is constantly zooming up and down various heights at high speed. Like fall 8ft, rise 4ft, drop 2ft, raise 5ft, etc... to match the screen movement.
When your banshee is banking upward it's rapidly going up so you're pushed down into your seat. If it's falling or diving, the room is dropping so you get feels in the tummies.
I'm convinced at this point that some people are immune to those sorts of sensations. The people who don't feel an elevator moving or notice turbulence in an airplane.
As far as overheating and such - don't know, but with the speed at which it moves 6 large guest filled rooms at once it seems plausible.
