I'm with you, I don't think the 60fps would be fast enough, I don't think it would give you realistic motion, even with your fake fall lasting in real time much longer than if you really fell off a building that tall. The biggest giveaways would be the flapping of clothes, skin, hair, etc... which wouldn't be at the realistic rate.
I think the harness, fans, and greenscreens etc. are all workable. But I think I'd use a faster camera, and I definitely wouldn't use a DSLR unless that's the only real choice. Sounds like a job for the Phantom or other legit high-speed camera..... Phantom Flex, or HD GOLD or whatever. Shoot it with your wind machines, etc., but the actual
duration of the shot in real time would be about the same as it would actually take a person to fall that distance.
How long would it take to actually fall 11 stories? I dunno (although it's probably easily enough researchable), but just as an example I'm guessing 5 seconds. If that were the case, a real shot for 5 seconds at about 300fps (which would stretch the shot to more or less 60 seconds) would probably look pretty realistic. I'd really crank that wind machine up.
If you
have to shoot it with a DSLR at 60fps, you might be able to stretch it to :30 if you use Twixtor or some other frame interpolation software to double the frames (effectively giving you a 120fps framerate).
