Once the first suspended floor fell it overloaded the second then the third etc.
I don't have any proof of any of this, just an engineer friends explanation - and haven't cared much to follow up on it. But by this explanation it would make sense by how it collapsed, and that there wouldn't need to be a lot of damage to force it - just high temperature on the top floor.

Just so you know, all the bullshit about temperatures and that is, well, bullshit. I'm a fireman. In NYC. fires here regularly get over 2000 degrees, and that's just couches and shit burning. Steel loses something like 40-60% of it's strength at 1000 degrees, as well as expanding a great deal. Those two factors alone, are what caused the towers to come down.
I will not comment on this anymore, 343 men from my job gave their lives that day. For me, that's enough.
