No diveconmoron building fires are the official collapse theory and for good reasons if the structural damage was factored into the computer model a symmetrical collapse was impossible to simulate so it became not a factor because it did not fit...that's called

following an extensive, three-year scientific and technical building and fire safety investigation.
This was the first known instance of fire causing the total collapse of a tall building, the agency stated as it released for public comment its WTC investigation report and 13 recommendations for improving building and fire safety.
Our study found that the fires in WTC 7, which were uncontrolled bu
t otherwise similar to fires experienced in other tall buildings, caused an extraordinary event,”
computer simulations show that neither explosives nor fuel oil fires played a role in the collapse of WTC 7,” Sunder said. The NIST
Finally, the report notes that “while debris impact from the collapse of WTC 1 initiated fires in WTC 7, the resulting structural damage
had little effect in causing the collapse of WTC 7.” NIST WTC 7 Investigation Finds Building Fires Caused Collapse, 08/21/08
The investigation team considered the possibility of other factors playing a role in the collapse of WTC 7,
including the possible use of explosives, fires fed by the fuel supply tanks in and under the building, and damage from the falling debris of WTC 1.
The team said that the
smallest blast event capable of crippling the critical column would have produced a “sound level of 130 to 140 decibels at a distance of half a mile,” yet no noise this loud was reported by witnesses or recorded on videos.
so this is the sole reason given for rejection of the controlled demolition theory...what if the critical column was treated with thermite paint and super heated how much of an explosion would it take then ? and there were indeed massive explosions witnessed..so if it can be done at a lower decibel level it must then become a more viable theory..
