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"

I saw an interview of fire fighters that took place maybe a year or 2 after. One fireman said he saw molten steel flowing down "it looked like a foundry" were his words.

I actually saw the video on this when it was happening.You literally could see what looked like hot lava pouring out of (a few) of the windows.That's a trademark of thermitic detonation, because thermite generates it's own heat, very intensely-and contains it's own oxygen as it burns.I am positive that the videos i've seen are genuine.
