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 government was a large part of what happened that day. Firstly because they ran an unprecedented number of drills that for the first time in history left most of the US unprotected. Drills carried on until 9/11 was basically over. They included hijack scenarios and putting fake radar blips on the screens. The Al Qaeda did exist, they trained at various flight schools but the probability they even could fly commercial jets let alone pull off the maneuvers they are supposed to have is basically zero. I think most researchers think the planes were swapped in mid air. Most likely the people on the flights were killed. The flight that crashed at shanksville didn't really crash there. The official story was just total fantasy. The flight was shot down, and the wreckage was found over something like a 7 mile radius. Most likely they invented some ridiculous story because if that plane was shot down, then why weren't the others. Air traffic controllers thought the plane that was headed towards the pentagon was a fighter jet or something similar, due to the speed and the way it was moving. The towers were blown up controlled demo style.
