One very morbid question I have is were some of the jumpers actually pushed? Some of the pictures you see people crowding to the few available edges, a crush of bodies trying to breath. Wouldn't some of the people on the edges have been pushed by those further inside?

It's possible. In this video you can see 8+ people jumping within a couple of seconds of each other from approximately the same place: https://youtu.be/b9QN3AkydYY?t=344

Or perhaps unintentionally knocked off and people crammed the edge. There is no way to know.
