From that Monbiot article PMM links to:

===========

The failure of the Twin Towers has been exhaustively documented by the National Institute of Standards and Technology. Far from being impossible, the collapse turns out to have been inevitable. The planes cut some of the support columns and ignited fires sufficient to weaken (but not melt) the remaining steel structures. As the perimeter columns buckled, the weight of the collapsing top stories generated a momentum the rest of the building could not arrest. Puffs of smoke were blown out of the structure by compression as the building fell.

Counterpunch, the radical leftwing magazine, commissioned its own expert – an aerospace and mechanical engineer – to test the official findings. He shows that the institute must have been right. He also demonstrates how Building 7 collapsed. Burning debris falling from the twin towers ruptured the oil pipes feeding its emergency generators. The reduction in pressure triggered the automatic pumping system, which poured thousands of gallons of diesel onto the fire. The support trusses weakened and buckled and the building imploded. Popular Mechanics magazine polled 300 experts and came to the same conclusions.
