If you don’t believe that members of Al-Qaeda hijacked planes and flew them into the World Trade Center, The pentagon, and another one that crashed in Pennsylvania, then what do you believe happened?
Do you think that these were some sort of remote controlled drones and the operation was carried out by the United States government? That the people inside those planes were unwitting victims or were entirely made up?
Do you think that that the men who hijacked the plane were actually agents for another group/state other than Al Qaeda?
Do you think that it was Al Qaeda, but the government knew it was going to happen and allowed to to go ahead anyway?
Or do you think it was something else?
The side of the building was ripped yet it collapsed inward instead of sideways?
The collapse pattern is not at all unusual or suspicious for the building and the damage it sustained. This is a video of a simulation based off of the NIST investigation into WTC7 that shows you how it happened. https://youtu.be/VAkTbyENZ5s
