I'm not an engineer. All I know is the building caught fire and it didn't collapse. Wait, I know a little more. Only three steel-frame high rises have caught fire and completely collapsed. They all had WTC in their names, were all leased by the same person, they were all within a few hundred yards of each other, and they all collapsed on the same day. Wait. Wait. I know a little bit more. I know I'm supposed to ignore all of that and believe the government, cuz, you know, 'murica.
That's some conclusion you have come too.
Thanks for that, it explains more than you will ever know
