Wow. Interesting. It happens so quickly that it looks as if he belly-flops, but if you watch frame by frame, he actually hits the pavement hands-first. However, the speed at which he falls is so great that his arms snap instantly and his belly then hits the pavement, thus the very next frame showing his organs being forced from his mouth and shit/intestines being forced from his ass.
That said, I have a feeling that those who jumped from the WTC likely didn't have their organs forced through their orifices, as I believe that fall was so high that their entire bodies essentially exploded.
