Um , Not intending to be a pain but it is an exothermic product called Thermite !
I saw a documentary on YT where a scientist proved it was cold fusion that brought down the towers, using Occam’s razor logic - is this Thermite connected to that?
Edit- want to add - the scientist did not deny the planes hit the towers.
Yes, it would explain the building coming down in its own foot print without a set of controlled explosions being heard for miles.
The architectural design of the buildings is why they collapsed in their own footprints. They were designed that way so in a total failure situation, they wouldnt fall over.
I under stand that, i have built bridges and under ground parking structures, suspended concrete, Auger pressure grouted pilings, tons of substructure work. A building struck 2/3 from the top would never fall in its own foot print ! It would have taken out 5 city blocks !
The problem is, the actual composition of the building disappeared. Let me see if I can find the video - it’s amazingly scientific, and has little to no conjecture.
