Everyone who has researched know that it was an inside job. The people in the government themselves were involved in planning the attacks
and designing it. There are a lot of documentaries about it. the main thing, Buildings wouldn't have collapsed just by the plane !!!!!
It require explosive to cause that damage.

Sure, the fires started by the planes's fuel and impact can and did cause that collapse.
It's silly and naive to think explosives were required. The potential energy of those high buildings themselves was far in excess of energy of explosives. All it took was a triggering event.
Sure there are some crap documentaries. There are also documentaries about space aliens and monsters in the dark.
As Spendy says, there are no mysteries. It was clearly an inside job.

Not only is there no proof that the fires had anything to do with the collapse, but there is no way to prove it if they did. Why not? Because there was little investigation into the "parts" of the collapsed buildings before they were carted off to China or wherever.
Any other disaster would have taken years of investigation, even if officials knew exactly what happened. Not the 9/11 Towers. They didn't want the proof that it was an inside job to be shown.
Two major things show the inside job:
1. Not enough heat, as shown by photos of people walking around in the damaged areas, right where the heat was supposed to be greatest;
2. Building collapse into its own footprint, at free fall speeds, as only could have been done by demolition.
