There are literally pictures of body parts that fell to the street from the day too. Not to mention things from inside the buildings, paper, office supplies. I don’t think people fully comprehend how fast the planes hit and how that scatters the contents. The stuff not bolted down just keeps going unless something stops it.

One passport surviving? If anything, I’m surprised there weren’t more. The black box? It was physically attached to the thing, it isn’t going to go far.
