If Jet fuel can melt steel, and office fires cause building collapses, I must be a sheep.

How can something fall at free fall speeds if there is material in the way?

So the build fell at greater than terminal velocity?

Jet fuel burnt up pretty quick.

Im not saying Im taking one side or another, I do know that jet fuel cannot make a fire hot enough to weaken, or even melt steel to the point of structural failure, and a building cannot have an asymmetric damage, and fall symmetrically, all while falling at free fall speed. If you dropped a ball by the tower at the same time as the tower fell, they would both hit the ground at the same time, how is this possible when NIST specifically said that the floors were pancaking, therefore the floor above it should fall far slower than the speed of gravity due to the upward pushing force of the floor below the floor falling, another thing, if the fires were so hot that they could melt steel, 2100 degrees, then how were people simply able to walk down the floors that were on fire without being burned.. as many people said walking down the south tower- the fires were out, almost completely starved of oxygen due to the building office codes for fire resistant materials and office space. IM saying it doesn't make sense.

NOOOOO!!!!!!!!!!!!!

first of all the jet fuel argument is retarded. fire is hot, fire causes metal to weaken and expand.

the reason the building pancaked the way it did is because the WTC complex had massive generators in the underground portions of its building. the impact and fire resulted in a rupture in the generators which caused a fire below (I think it was diesel fuel). this weakened the support structures and caused the buildings to collapse into the voided underground space (yes this is true for WTC7 as well)

again, popular mechanics did an awesome job of explaining this

It was the flouride in the water from the sprinkler systems that caused it to crash to the ground at supersonic speeds.

where did you come up with that?
