They didn't show the jumpers, but they put int the sound of their bodies hitting the cover over the walkways, and showed the firemen directing those evacuating away from where the bodies were falling, and yelling about why the evacuees were being redirected. The sound was probably worse than the sight would have been.
They didn't pull that particular punch at all, IMHO.
You are right and the bodies hitting sounded about like they do in the French brothers documentary about the probie NYC fireman. They made it a little louder in The Path, I thought.
Was the movie tonight as it was the first night? ABC.com has both the videos to download, but I'm not sure if it would be worth it.
