the thing that gets me is how all the towers fell straight down - you would think they would fall a couple of degrees off center at least...

Oh yeah, and the pentagon's $2.3 trillion that went missing announced on 9/10

I'm extremely confident in saying that the way the Twin Towers fell is entirely explainable by their shoddy 70s new age construction. Remember, their structural stability relied on the outer web of steel, not a steel and concrete core like most skyscrapers. The heat of the fires caused the steel that supported the floors to deform and sag (not melt!), which pulled the outer web of steel inwards. The stress of being bent and pulled in by the sagging floors while having to support the rest of the building above caused the outer steel at those floors to break at some points. When some of these beams broke, it increased the load on surrounding beams, which also broke. Eventually there wasn't enough strength to support the rest of the building above, so the entire thing catastrophically fell down into the next floor, which instantly failed, leading to a chain reaction.

Building 7 was sketchy as fuck. "Pull it"

Nah those towers were built to last. They were built to survive major earthquakes and hurricane force winds. Jet fuel doesn’t burn hot enough to melt the steel used in the construction of the twin towers. Also George Bush’s cousin recently became the CEO of the security company that was contracted to protect the towers. 2 weeks before the attack the did a so called security update on the software and cameras within the tower. Think of that what u will. Also why did they sell all the scrap steel to China after the attack during the clean allowing no scientist to examine the steel. That’s just a drop in the bucket of info we were never told.
