And just to add another 2 cents to the "melting steel" topic.
"Melting steel" and "weakening it to the point of failure" are 2 totally different things.
One of the first things I learned was difference between wood and steel in fires. Wood will burn, but it will keep most of it's strength until it burns through. Steel, as soon as it gets hot, will start to warp and bend. You do NOT need to melt steel to weaken it and make it fail, just heat it up enough. And like I said before, trusses are already pretty weak and flimsy (cheap) to begin with. And add the heat with the fact that a few floors were blown out by a giant plane, it's pretty reasonable that it would fail.
