Once again you still haven't shown any footage other than the most basic bitch /pol/ grab bag of videos. See that huge fucking chunk of the building missing from right behind the reporter? Think that shit is important for structural stability? Or how about 5 floors of uncontrolled fire that is getting a great amount of oxygen since all of the windows are bursting out from the heat? Review the raw footage all you want: https://www.youtube.com/watch?v=t5tEy6mXSE8 the building was absolutely fucked up before it collapsed and the fire weakened, not melted, the steel frame enough that it caused a chain collapse from the bottom up.

When doing conspiracies you keep it simple, or it will leak before or after, or fail due to excessive complexity. The government ignored any and all attempts to avert the attacks, James Woods the voice actor reported the hijackers doing practice runs on his flight that August, something the FBI did confirm. And recently its turned out that one of the intelligence agencies regarded one of the hijackers as an asset and I believe I read that they were paying his motel fees during his "pilot training."
