Thermite is an incendiary. Its detonation velocity in either concrete or steel is insufficient to destroy those materials, or create any of the observed effects, like horizontal ejection of large segments of the exterior steel frame of the towers.
At most, thermitic material was used for cutter charges in the towers.
Building 7 is a different matter.
It still lacks the detonation velocity to cause explosive effects in dense materials like concrete and steel. The DV must be at least equal to the speed of sound in the material.
Even superdooper nanothermite falls far short of the required DV for concrete or steel. That’s just the physics of construction materials and the laws of explosives. No secret to those who blow up buildings for repurposing sites; but something that AE911Truth has steadfastly refused to address for more than a decade.
It’s all laid out in any of the US Army explosives/demolition handbooks that are available online.
