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.
