I really don't know. I think only a structural engineer could answer those questions. Probably due to the steel structure versus wood. They had interviews with structural engineers who explained it all - the temperature and force required to collapse/bend the steel. It took time for the burn to reach that temperature. According to the interviews I saw, the building would have to reach an unbelievably extreme temperature and then the steel would in essence, just fold up (melt) rather than bend due to the design. I saw live footage of both planes striking the building (and video later) so it seemed entirely plausible to me. There is just too much evidence that those two plains hit the towers and brought the building down to take anything else seriously (although everything should be considered).

>Second tower was hit higher up to the left. It piersed trough building, flames comming out both on a side, and back of the builduing.
>If impact/explosion had blown away internal wals making huge hole/damage LEFT to the vertical axis, wld it be normal for a tall object to colapse - sideway ? (like when timber is cut)
