NIST says the cause of collapse at WTC 7 was fire, so that is what I am addressing. All modern hirise buildings are constructed of steel/concrete, including the ones I noted for you.Twin towers.
1. Hit by a jet in the upper third, damaging support steel
2. Fires then ensuing after impact
3. The same tube in tube, all steel design
WTC7.
1. Same design as WTC7
2. Unfought fires because of no sprinkler system
Point out which buildings you have as a comparison that match those characteristics. If you can;t then you have NO COMPARISONS in which to prove me wrong.
I'll wait right here.
They like WTC 7 were not struck by any planes, so I ask you again, why, in your opinion, did the WTC7 collapse from fire,
and with such uniformity, while the others did not?.
Also why in your opinion, did the N tower not exhibit any sign of steel beam or column failure in the 1975 fire? There were no sprinkler systems in place at the time.
And BTW the empire state building was struck by a plane in 1945, a fire ensued and people were killed, yet it did not exhibit any sign of collapsing.
