This video compilation clearly shows multiple explosions and detonations in the twin towers on 9/11. Watch the tower that has already been hit by a plane when the second plane hits. They used the second plane hit to cover detonations used to weaken the other tower. You see multiple black puffs of smoke explode out of the floors above the plane impact area. Also visible throughout are flashes of explosions and other squib detonations. It is a long video, so give yourself some time to watch it. It is well worth it if you want to learn the truth about that day.
