Keep in mind the tremendous kinetic energy of an airliner moving at 400 miles per hour, and the fact that energy was transmitted in a split second. Then the fire.Dabu wrote: Well the 9/11 commission report is lacking a lot of info.
I'm really curious about how a fire caused a steel building to collapse at the rate of free fall when jet fuel can not burn hot enough to melt steel.
I'm curious of how a fire caused some very heavy steel support beams to be projected 400 feet into the sides of adjacent buildings.
What really bugs me is how building 7 collapsed when a plane didn't even hit it, and the buildings adjacent to towers 1 & 2 didn't collapse.

jtallen83: If the trusses that support the floors failed, why would the structural steel beams fail if they no longer had a load to support?
