If you look carefully at the collapse of the towers you see the interior part of the building’s collapse first and follows the rest of the tower falling in on itself. The force of the interior falling into itself would cause the the expulsion and jettison of the cladding and blow out the windows as the tower fell. The interior structure was massive steel columns they had to Literally turn to dust for that to happen. The only way was a fission Nike placed below the last sub basement. That type of nuke would have turned the steel and everything else to dust. I’ll post a picture of a Russian study that has since disappeared from the internet. I have a picture on my phone but don’t know how to get it on this board.
