Structural metal bending in a fire, reminded of 9-11

I need to clarify: The reason I talked about melting temperature was that it was often brought up in these discussions. It seems to me that in order for the towers to fall so neatly into their own footprint, the metal would have to melt, not bend. I would think that bending metal would cause the tower to careen sideways, not fall neatly. This building is strong enough to withsatnd high winds over a large surface, but then ever so neatly falls down? Hmmm.
OTOH, what I'm overlooking is the marvel of the building design to begin with. The thing is that tall, that heavy, can withstand those winds, heat expansion, cold contraction, and last those many years, and I don't regard it as amazing? It_might_be_possible that in addition to those qualities, it could also be designed to fall neatly. I'm doing the same thing as the atheists in overlooking the wonder of the original design.
