in order to bring down a building of that size, of that design, at that speed, collapsing with that level of symmetry, all of the support beams have to fail simultaneously
do i have to explain why that is?
and all of the support beams won't fail simultaneously due to fire and the impact of debris because they are made out steel, which is unaffected by conventional fires
unless you believe this debris hit all of the support beams in such a way that they all then failed simultaneously, several hours later
of course magical peer reviewed papers have proven the official story and anyone doubting them is insane
but the art of deduction is to rule out the impossible and examine what is left
the official story, no matter how many papers insist that it's possible, is not in fact possible

>nope
yet
>NIST acknowledges that WTC 7 fell at a rate of free fall (or the rate of gravity) for a period of approximately 2.25 seconds before it started to slow down
