We do not know the exact events that happened during the black screen, so we will say that they begin falling at 2:06. It is reasonable to assume terminal velocity is reached in 15 seconds, and that one will fall 400 metres in that time. However, due to their extra drag from his jacket and her dress, we will assume they reach terminal velocity in 19 seconds, at 2:25. It takes 85 seconds to watch them at the end of their falling. Our charity to this video?s realism will continue by multiplying 85 seconds by terminal velocity. We will then let terminal velocity be 50 m/s.
50 m/s times 85 s is 4250 m.
4250 m is 13943.4 ft
400 m is 1312.32 ft

13943 + 1312=15255
So we could say the tower is 15500 feet high, as she wasn?t at the top.
People could barely breath at such an altitude, and the change in pressure from falling would cause many problems of it?s own. They wouldn?t be just chilling like that. But to anyone who wants to make a 16000 foot tower, good luck. Just remember to have oxygen masks at that altitude. And this is assuming that the ground is ocean level.
