As i have stated numerous times, i don't think conventional explosives were used, but thats not important, what is important are the numerous
characteristics that arise from the buildings collapse that are evident and which we can see from watching the horrifying events of that day. We
obviously cannot prove to you exactly what type of explosive was used and so, but then again if NIST conducted its research in a correct manner we
would not have received this nonsense:
Did NIST look for evidence of the WTC towers being brought down by controlled demolition? Was the steel tested for explosives or thermite residues?
The combination of thermite and sulfur (called thermate) "slices through steel like a hot knife through butter.
NIST STATEMENT: "NIST did not test for the residue of these compounds in the steel."
If they had tested for these compounds we could have determined what type of explosive was used and so on.
Molten steel was found under ALL 3 buildings. How is it possible for molten steel to be found under WTC7 when no plane crashed into it, thus no jet
fuel, also the fact that no steel framed building has ever collapsed due to fires, so once again how did WTC7 collapse without the means of some sort
of explosive?
Moreover,
Although virtually all of the structural steel from the Twin Towers and Building 7 was removed and destroyed, preventing forensic analysis, FEMA's
volunteer investigators did manage to perform "limited metallurgical examination" of some of the steel before it was recycled. Their observations,
including numerous micrographs, are recorded in
Appendix C of the WTC
Building Performance Study. Prior to the release of FEMA's report, a fire protection engineer and two science professors published a brief report in
JOM disclosing some of this evidence.
They reveal a phenomenon never before observed in building fires: eutectic reactions, which caused "inter granular melting capable of turning a solid
steel girder into Swiss cheese." The New York Times described this as "perhaps the deepest mystery uncovered in the investigation." WPI provides a
graphic summary of the phenomenon -

FEMA's investigators inferred that a "liquid eutectic mixture containing primarily iron, oxygen, and sulfur" formed during a "hot corrosion attack
on the steel." The eutectic mixture (having the elements in such proportion as to have the lowest possible melting point) penetrated the steel down
grain boundaries, making it "susceptible to erosion." Following are excerpts from Appendix C, Limited Metallurgical Examination.
Evidence of a severe high temperature corrosion attack on the steel, including oxidation and sulfidation with subsequent intergranular melting, was
readily visible in the near-surface microstructure. A liquid eutectic mixture containing primarily iron, oxygen, and sulfur formed during this hot
corrosion attack on the steel.
The thinning of the steel occurred by high temperature corrosion due to a combination of oxidation and sulfidation.
The unusual thinning of the member is most likely due to an attack of the steel by grain boundary penetration of sulfur forming sulfides that contain
both iron and copper.
liquid eutectic mixture containing primarily iron, oxygen, and sulfur formed during this hot corrosion attack on the steel.
The severe corrosion and subsequent erosion of Samples 1 and 2 are a very unusual event. No clear explanation for the source of the sulfur has been
identified. The rate of corrosion is also unknown. It is possible that this is the result of long-term heating in the ground following the collapse of
the buildings. It is also possible that the phenomenon started prior to collapse and accelerated the weakening of the steel structure. A detailed
study into the mechanisms of this phenomenon is needed to determine what risk, if any, is presented to existing steel structures exposed to severe and
long-burning fires.

We also know from numerous studies conducted by Professor Steven Jones on the theory of Thermate that characteristics such as severe corrosion, intra
granular melting, and abundance of sulfur are consistent with the theory.
Please watch the lecture of Professor Steven Jones below for an in depth analysis and research he proves without a shadow of a doubt that thermate was
used to destroy the buildings. He conducted his research using a Electron microscope and analyzed steel spheres from WTC site, what he found was a
thermate signature and compounds of thermate.
