I was quite interested to hear from one of our structural engineers earlier
today. Apparantly it wasn't the aircraft that caused the buildings to
collapse. The buildings were designed to take the hit of an aircraft.

What brought the buildings down was the fire. The buildings hadn't been
designed to survive a fire. When the structure became warm, the steel
supports were no longer strong enough to support the weight of the building
and so it gave way.
