I think i read somewhere that it took 1 minute (or something like that) to travel up (or down) the full 7 floors. So that would be about 10 seconds to travel 1 floor. But i can't find that source anywhere.
Does anyone know?
P.S. Was there a dividing wall between the 2 freight elevators (ie when the work crew were racing the elevators down, could the crew in the west elevator see the crew in the east elevator and visa-versa)?
