Just to summarize the thermate argument, there are several pieces of evidence which no other explanation can accommodate.
1. Videos of an molten metal flowing out of the South Tower of the WTC.
a.
Japansese News coverage (newer) video of South Tower
b.
Amateur Video of South Tower sparks.
Important facts that debunkers will usually avoid or fail to address about these videos:
* They look
like a thermite reaction.
* They show the molten metal to be flowing near the time of the collapse, at the very corner where the collapse begins.
* The time at which this reaction occurs is well after the jet fuel had burned off, yet displays temperatures that far exceed what an open air kerosene fire could produce.
* The amount of motel metal is in the tons
2. Molten aluminum is completely ruled out since it doesnt glow orange at any temperature reachable by jet fuel fire, and at
melting temperature is silver in color.
3. Independent research analysis of pieces of
molten iron taken from the WTC wreckage (pg 32) are found to have nearly exact features as thermate.
4. Newer scientific research of WTC dust samples shows just as exact a match of chemical signatures, not to mention a size of microscopic particle of molten iron not expected from a gravity driven collapse, nor expected to be so prevalent in the dust given some one-in-a-million spontaneous reaction like thermate from the exact combination of sulfur, powdered iron oxide, and fine powdered aluminum.
"The spheres from the thermite reaction...contain strong peaks for aluminum and iron, and for “thermate”; sulfur is also prominent. (Note that the iron-aluminum-sulfur spheres from MacKinlay’s apartment contained very low calcium, so the sulfur is evidently not from gypsum, a common building material)." - Steven Jones
