NIST AND NANO THERMITE
NIST (NANO THERMITE)
Top 10 Connections Between NIST and Nanothermite
22. Did the NIST investigation look for evidence of the WTC towers being brought down by controlled demolition? Was the steel tested for explosives or thermite residues?
“NIST did not test for the residue of these compounds in the steel.
The responses to previous questions demonstrate why NIST concluded that there were no explosives or controlled demolition involved in the collapses of the WTC towers.
As for thermite (a mixture of powdered or granular aluminum metal and powdered iron oxide that burns at extremely high temperatures when ignited), it burns slowly relative to explosive materials and would require several minutes in contact with a massive steel section to heat it to a temperature that would result in substantial weakening. Separate from the WTC towers investigation, NIST researchers estimated that at least 0.13 pounds of thermite would be required to heat each pound of a steel section to approximately 700 degrees Celsius (the temperature at which steel weakens substantially). Therefore, while a thermite reaction can cut through large steel columns, many thousands of pounds of thermite would need to have been placed inconspicuously ahead of time, remotely ignited, and somehow held in direct contact with the surface of hundreds of massive structural components to weaken the building. This makes it an unlikely substance for achieving a controlled demolition.
Analysis of the WTC steel for the elements in thermite/thermate would not necessarily have been conclusive. The metal compounds also would have been present in the construction materials making up the WTC towers, and sulfur is present in the gypsum wallboard that was prevalent in the interior partitions.”
NIST’s acknowledges that Thermite CAN in fact cut through the massive steel in WTC in direct contradiction to the many reports and supposed experiments that supposedly “proved” it could not. Thermite burns at 2500ºC (4532ºF), and according to NIST here, it would take truckloads of it to “substantially weaken HUNDREDS of MASSIVE structural components”
“”N.F.P.A. 921- 19.2.4 Exotic Accelerants states that molten steel and concrete could indicate the use of exotic accelerants, specifically Thermite.”

NIST (MOLTEN METAL)
Here are several answers given by NIST which they confirm molten steel was witnessed. However, John Gross, lead NIST investigator denied any reports of Molten steel.
23. Why didn’t the NIST investigation consider reports of molten steel in the wreckage from the WTC towers?
“NIST investigators and experts from the American Society of Civil Engineers (ASCE) and the Structural Engineers Association of New York (SEONY)—who inspected the WTC steel at the WTC site and the salvage yards—found no evidence that would support the melting of steel in a jet-fuel ignited fire in the towers prior to collapse. The condition of the steel in the wreckage of the WTC towers (i.e., whether it was in a molten state or not) was irrelevant to the investigation of the collapse since it does not provide any conclusive information on the
condition of the steel when the WTC towers were standing.
Under certain circumstances it is conceivable for some of the steel in the wreckage to have melted after the buildings collapsed. Any molten steel in the wreckage was more likely due to the high temperature resulting from long exposure to combustion within the pile than to short exposure to fires or explosions while the buildings were standing.”
NIST admits that there is no evidence that steel can melt from a jet fuel ignited office fire. They claim the molten steel could have come from “long exposure to combustion” in the pile.
Let’s look up the word combustion….
( /kəmˈbʌs.tʃən/) or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species.”
This chemical sequence created iron oxide and aluminum sulfide. aka Nano Thermate.
13. Why did the NIST investigation not consider reports of molten steel in the wreckage from the WTC towers?
“NIST investigators and experts….
NIST considered the damage to the steel structure and its fireproofing caused by the aircraft impact and the subsequent fires when the buildings were still standing since that damage was responsible for initiating the collapse of the WTC towers.……..the buildings were standing.”
15. Since the melting point of steel is about 1,500 degrees Celsius (2,800 degrees Fahrenheit) and the temperature of a jet fuel fire does not exceed 1,000 degrees Celsius (1,800 degrees Fahrenheit), how could fires have impacted the steel enough to bring down the WTC towers?
“In no instance did NIST report that steel in the WTC towers melted due to the fires. The melting point of steel is about 1,500 degrees Celsius (2,800 degrees Fahrenheit). Normal building fires and hydrocarbon (e.g., jet fuel) fires generate temperatures up to about 1,100 degrees Celsius (2,000 degrees Fahrenheit). NIST reported maximum upper layer air temperatures of about 1,000 degrees Celsius (1,800 degrees Fahrenheit) in the WTC towers (for example, see NCSTAR 1, Figure 6-36).
However, when bare steel reaches temperatures of 1,000 degrees Celsius, it softens and its strength reduces to roughly 10 percent of its room temperature value. Steel that is unprotected (e.g., if the fireproofing is dislodged) can reach the air temperature within the time period that the fires burned within the towers. Thus, yielding and buckling of the steel members (floor trusses, beams, and both core and exterior columns) with missing fireproofing were expected under the fire intensity and duration determined by NIST for the WTC towers.”
21. Why does NIST state that a yellow stream of molten metal seen in some photographs pouring down the side of WTC2 was aluminum from the crashed plane, even though aluminum burns with a white glow?
“NIST reported (NIST NCSTAR 1-5A) that just before 9:52 a.m., a bright spot appeared at the top of a window on the 80th floor of WTC 2, four windows removed from the east edge on the north face, followed by the flow of a glowing liquid. This flow lasted approximately four seconds before subsiding. Many such liquid flows were observed from near this location in the seven minutes leading up to the collapse of this tower. There is no evidence of similar molten liquid pouring out from another location in WTC 2 or from anywhere within WTC 1.”
9/11: South Tower Collapse (ABC Live)
The flow starts at 25 seconds and continues until 1:45 then the building collapses 15 seconds later. NIST states that the “flow lasted approximately four seconds.” This is a blatant lie since this video is proof that the flow lasted for nearly 1 minute and 20 seconds.

16. Was the steel in the WTC towers certified by Underwriters Laboratories (UL) to 1,100 degrees Celsius (2,000 degrees Fahrenheit) as some have claimed?
“UL did not certify any steel as suggested. In fact, in U.S. practice, steel is not certified at all; rather structural assemblies are tested for their fire resistance rating in accordance with a standard procedure such as ASTM E 119 (see NCSTAR 1-6B). That the steel was “certified … to 2000 degrees Fahrenheit for six hours” is simply not true.”
“None of the recovered steel samples showed evidence of exposure to temperatures above 600 degrees C for as long as 15 minutes.” NIST, p. 180
“Only three of the recovered samples of exterior panels reached temperatures in excess of 250 degrees C during the fires or after the collapse. This was based on a method developed by NIST to characterize maximum temperatures experienced by steel members through observations of paint cracking.” NIST, p. 181
“All four test specimens sustained the maximum design load for approximately 2 hours
without collapsing” NIST, p. 143
NIST engineer John Gross denies WTC molten steel (extended)
“I know of absolutely nobody, because no eyewitnesses said so, nobody who’s produced it…” -John Gross, lead NIST engineer when asked about the molten metal at ground zero.
World Trade Center USGS Thermal
Images of the World Trade Center Site Show Thermal Hot Spots on September 16 and 23, 2001.
“AVIRIS records the near-infrared signature of heat remotely. The accompanying maps are false color images that show the core affected area around the World Trade Center. Initial analysis of these data revealed a number of thermal hot spots on September 16 in the region where the buildings collapsed 5 days earlier. Analysis of the data indicates temperatures greater than 800oF. Over 3 dozen hot spots appear in the core zone.”
“For temperatures in the 800-1000 Kelvin range, temperature accuracy is estimated to be ± 30 Kelvin and the area ± 5%. For smaller spots, like spot G in Table 1, the temperature accuracy is similar, but the accuracy on such small areas is approximately +5%, -0.5%. For example, decreasing the temperature to 1000 Kelvin (from 1020 Kelvin) on spot G increases the fractional area to about 5%.
Positions, temperatures and equivalent areas for hot spots A-H are given in Table 1 and the geometrically rectified location map is shown in Thermal Figure 8.”
