9/11 Tower Vertical Beam Disintegration Debunked?
High resolution video suggests steel beams remained intact as they collapsed
Horizontal floors and beams were disintegrated with nanothermite (NT). We can see beams act like bottle rockets as they change direction in mid-air due to the exothermic reaction acting like rocket fuel.
Firefighters described a river of molten steel underground that remained over 1000 deg for about 2 months...just like NT would behave.
Burned vehicles parked in the street were a result of NT that spilled onto them rom the floors above. --
The NT disintegration was required to prevent flooding of S. Manhattan if the full weight of the buildings and horizontal floors succeeding in cracking the water-proof basin surrounding the building site.
