The whole structures of the 3 towers hold on until point of collapse then all of the steel beam collapsed onto themselves through the path of most resistance like the video demonstrate.
I said, office fire cannot significantly weakened steel to the point all the steel beams would fell straight in their own footprint through the path of most resistance.
Even if the Steel would have been weaken by any amount of %, the way the towers felt straight through the past of most resistance defies the laws of physics if we are to believe the official version.
Your comment in noway refute what I said.
Welcome on Steemit as this seems your very first comment ever, after just receiving your account today.
Also, ignore the fact that on the video, with careful observation, you can clearly see that the center columns collapsed first. They were not damaged by "isolated fires." That building was demolished. Period. Next question please...
