The World Trade Center buildings 1, 2 and 7 were wired in advance for controlled demolition
The wiring of these buildings was done by a black ops team plus the Mossad during the evening and early morning hours in the weeks leading up to 9/11. The Mossad were assisted by the Israeli Art students who were living in WTC 1. This is the 9-11 Team.
The command center was in Blg 7 and this was where the entire 9-11 crime was managed from.
The WTC 1, 2 and 7 were wired for controlled demolition. The planes would not have caused 1 and 2 to collapse like they did. The most complex demolition project ever done was the controlled demolition of the WTC and it was a textbook example of how to bring down these large skyscrapers. Even BLG 7 was done superbly by this team. They were experts, or the people mentoring them were experts.
The only problem was that their sequence of detonations was messed up. They had bombs going off at random times and in highly unlikely places such as the basement. However, they did not care. They must have watched the whole thing play out from Blg 7 where they had detonation matrix control panels (computers) set up. Although commercially controlled demolitions are normally sequenced on sophisticated computerized timers, these guys seem to have used manually controlled detonation networks all from Blg 7.
After the planes hit they would go to work to detonate key support elements within WTC 1 and 2.
Meanwhile, the 2 flights that crashed into the WTC had no passengers on them. They were military drone aircraft that looked very similar to the commercial aircraft they were supposed to be.
These aircraft flew faster and more acrobatically than a standard airliner could especially with an inexperienced terrorist pilot.
These planes might have been "steered" by the 9-11 team in Blg 7.
After the WTC 1 and 2 buildings collapsed, the team left Blg 7 and then they blew Blg 7 ( and all the evidence) up. The firemen did not blow it up, the 9-11 team blew it up, just like they did Blgs 1 and 2.
