P.S. I officially believe that those buildings fell because two big ass planes hit them and took out the center structural support, plus the added weight of airplane fuselage to the already stressed bolts that held the floor pans full of concrete gave way and pancaked through the center of the building to the ground...so your "troofer" thing doesn't bother me at all lol.
I did commercial concrete for almost 10 years before landing on this shit heap. I've seen 2 inch thick bolts sheer under the right kinds of pressure. I've seen chains snap and solid steel cables stretched twice their length. There was a great amount of pressure that hit the WTC that day and a lot of shit got twisted and moved beyond the amount of play that the engineers had designed it for.
But...I could be completely, 100% wrong on that. The difference between you and me is, I've got enough sense to realize that.
Happy monday btw.
