Reply #48: This and that

Why have you got express elevators in your diagram (the first one), when there were no express elevators where the planes hit in either tower?

It makes no difference whether the fuselage hits a floor slab, because it's going to break up anyway, it's important whether the engines hit floor slabs, though.

You've got a picture of a core column, but we don't know which floor it was from and it's hollow inside anyway.

"I don't think the plane would have sliced through these, so it should have exploded after going about one-third of the way in, see here:"
That doesn't make any sense to me. Why are you measuring it from when the nose hits - there's no fuel in the nose? You should be measuring it from when the fuel tanks hit. You don't even mention how many frames it is per second? Would that be 29? Why should it explode after x frames? It's supposed to take a second or two to explode.
