Nanothermite: If It Doesn’t Fit, You Must Acquit!

Nanothermite: If It Doesn’t Fit, You Must Acquit!

T. Mark Hightower (with Jim Fetzer)

Those who remember the 1995 O.J. Simpson trial will recall the gloves that turned out to be “too small” for O.J.’s hands when the long-awaited day of trying them on in the courtroom finally arrived. The blood-soaked gloves (one found at the crime scene and the other outside O.J.’s house in Brentwood the morning after his former wife was murdered) were gloated over as “hard evidence” by the prosecution and the media, very comparable to how the discovery of unignited nanothermite chips in the WTC dust is considered to be “hard evidence” of the explosive demolition of the Twin Towers on September 11th, 2001.

Although some have expressed skepticism about what is often called the “smoking gun” of 9/11, the great majority of 9/11 Truthers have accepted – and many have celebrated – this discovery, confident that it will lead to “a new, independent investigation” of the event and bring the perpetrators to justice. But precisely how did the resulting “nanothermite theory” of destruction of the Twin Towers come about – and how well does it stand up to critical scrutiny?

Why Nanothermite?

Observations by first responders of apparent molten metal – thought to be molten iron – could be explained by thermite reactions, which, in turn, could possibly explain the severing of steel columns through a process of melting. However, the explosive effects observed in the destruction call for some further explanation. Nanothermite has been identified as a candidate, being faster-reacting and alleged to be “an explosive form” of thermite.

In a paper titled “Why Indeed Did the WTC Buildings Completely Collapse?” (2006), physicist Dr. Steven E. Jones cited thermite to explain the molten metal and first started raising the possibility that nanothermite could explain the additional explosive effects observed. Then four dust samples collected in the aftermath of the towers’ collapse by different individuals were sent to Dr. Jones, and upon testing, they were found to contain unreacted red chips of a nanothermitic material.

Those results were reported in a later paper titled “Active Thermitic Material Discovered in the Dust from the 9/11 World Trade Center Catastrophe” by Niels Harrit, et al. (April, 2009), and because of this many assumed that nanothermite had been definitively identified as the prime candidate destructive agent. The paper, said to have been peer-reviewed, came out in the Open Chemical Physics Journal (Bentham Science Publishers), causing 9/11 Truthers to run with the news that explosive nanothermite blew up the Twin Towers, proclaiming what soon became a form of gospel in the 9/11 community. The Gospel of Nanothermite has given the incendiary properties of thermite a set of new miraculous powers: in its nano-state it becomes “Super Thermite” – a high-explosive that pulverized hundreds of thousands of tons of building materials in no more than 10 seconds.

A Literature Search

A scientific person, or one who prefers to use logic, might wonder about such claims and proceed by examining the scientific literature on nanothermite as well as the principle of how explosives achieve destructive force through generating shock waves that produce fragmentation. This might be a good time to note that the Rock Creek Free Press made a very important point in its May 2009 article on nanothermite: “To be a high explosive, the reaction speed must exceed the speed of sound in the material, which is unlikely in the case of thermitic materials, but nano-thermitic material may act as a low explosive in a manner similar to gunpowder.”

Few who have carefully watched video footage of the Twin Towers coming down could fail to notice what might appropriately be called “explosive effects” in the nature of the destruction. The question then would be: Were conventional explosives or some other kind of destructive energy source employed? If nanothermite is indeed a high explosive, then was it also necessary to use conventional explosives to achieve the demolition of the towers? The more sophisticated believer might agree that conventional explosives also could have been employed, but for the scientifically less sophisticated 9/11 Truther, the “Thermite/Nanothermite Gospel” says it all – and has been “conclusively proven” by the nine authors of the 2009 published and peer-reviewed paper.

But what does other peer-reviewed scientific literature actually have to say about nanothermite? “Nanoscale Aluminum-Metal Oxide (Thermite) Reactions for Application in Energetic Materials,” Central European Journal of Energetic Materials (2010), authored by Davin G. Piercey and Thomas M. Klapötke,

identifies the fastest known combustion velocity for a mixture of metal oxide and aluminum: 2,400 meters per second (m/s), in a type of nanothermite made of copper oxide and aluminum. Remember that what Steven Jones found in the dust was iron-oxide/aluminum nanothermite. The authors of this paper make it clear that copper-oxide/aluminum nanothermite is significantly more reactive than the iron-oxide version, and cite a combustion velocity of 895 m/s for an iron-oxide/aluminum nanothermite aerogel. So 895 m/s is the highest velocity yet to be found for an iron-oxide/aluminum nanothermite in the scientific literature, where this velocity is far too low to have played a significant role in the destruction of the Twin Towers by means of its shock waves.

Not Powerful Enough

Let’s examine the reason for that important last statement. The “destructive fragmentation effect” of an explosive is its detonation velocity, or the speed of the shock wave through the substance it is traveling in. To significantly fragment a substance, the detonation velocity of the explosive must equal or exceed the sonic velocity (the speed of sound) in the material. For example, the speed of sound in concrete is 3,200 m/s. In steel, the speed of sound is 6,100 m/s. Conventional high explosives such as TNT and RDX have detonation velocities of 6,900 and 8,750 m/s respectively, and are therefore capable of fragmenting concrete and steel, because both 6,900 and 8,750 exceed the sonic velocities of 3,200 m/s required to shatter concrete and 6,100 m/s required to shatter steel. As Dwain Deets has diagrammed, at only 895 m/s, iron-oxide/aluminum nanothermite does not come close to TNT and RDX.

However, prominent 9/11 researchers have

nonetheless termed nanothermite to be a powerful explosive. The very highly respected David Ray Griffin, Ph.D. calls nanothermite a “high explosive” in his July 6, 2010 article entitled “Left-Leaning Despisers of the 9/11 Truth Movement: Do You Really Believe in Miracles?”, which was published in the online journal, Global Research. “High explosives, such as RDX or nanothermite,” wrote Griffin, “could explain these horizontal ejections.”

Architects and Engineers for 9/11 Truth, the most revered of 9/11 research groups, published a piece called “Exotic High Tech Explosives Positively Identified in World Trade Center Dust” on April 5, 2009. In this they stated, “Ordinary thermite burns quickly and can melt through steel, but it is not explosive. Nanothermite, however, can be formulated as a high explosive.”

A “Secret” Technology?

While searching the open scientific literature on nanothermite and establishing the low detonation velocity of its iron-oxide/aluminum variety, chemical engineer T. Mark Hightower has been in contact and shared his findings with Dr. Steven Jones and the authors of the highly regarded April 2009 nanothermite paper, as well as with several other well-known 9/11 Truth leaders. The most recent responses to his challenges fall into two general categories. One response is that the combustion velocity of 895 m/s is enough to explain the Twin Towers’ destruction. The other is the rather persistent claim that nanothermite can indeed be a high explosive, where this formulation is a military secret that is not discussed in the open literature.

Alright. It is true that military explosives’ research employs nanotechnology and that applications involving nanothermite are a subset of this research. (The military even connects nanotechnology with mini-nukes, stating that a mini-nuke device the size of a suitcase could destroy an entire building.) But to suggest that the American military has a “secret recipe” that converts iron-oxide/aluminum nanothermite into a high explosive when this claim is contradicted by the open literature doesn’t make any sense.

Easily found in the open literature is that copper-oxide/aluminum nanothermite can have a combustion velocity of 2,400 m/s, compared to 895 m/s for an iron-oxide/aluminum nanothermite. If the 2,400 m/s number is not a military secret, why would a velocity greater than 895 m/s (for the iron-oxide variety of nanothermite) have to be kept secret? It is far more likely that the highest reported value of 895 m/s is due to physical property limitations of iron-oxide/aluminum nanothermite rather than a need to keep higher values secret.

“Combined” with Explosives?

Additionally – just to be safe, perhaps – 9/11 nanothermite advocates also maintain the fall-back position that, even if nanothermite by itself is not a high explosive, when combined with an organic substance (also asserted to not be itself a high explosive), a high-explosive is created. To that T. Mark Hightower responds: “There is only one sure way to make nanothermite a high explosive. If you combine enough high explosives with nanothermite, you can get a mixture that is a high explosive. But the same can be said for my breakfast cereal.”

Hightower has further calculated that if conventional explosives (such as TNT or RDX) acting alone were used to bring down the Twin Towers, the quantity necessary would have been hundreds of tons of explosives per tower. On July 27, 2011, Niels Harrit

(chief author of the 2009 nanothermite paper)presented a calculation for how much thermitic material would have been necessary to explain the presence of the many tiny iron-rich spheres in the dust (assuming that a thermite reaction was the source of the spheres).

He gave a range of numbers, based on lower and higher concentrations of the thermite formulation. His lowest figure amounted to 29,000 metric tons of thermitic explosive per tower – a value hundreds of times greater than the calculation for conventional explosives. His “conservative” estimate (based on 10% iron-oxide in the thermitic material) was 143,000 metric tons of thermitic material that would have been placed in each tower. But let’s be realistic: How could the perpetrators drag in and plant over 100,000 tons of explosive without being seen? Even 29,000 tons is hard to imagine and would have been rather difficult to put in place unnoticed.

The Missing Element

A side note from the many technical papers on nanothermite studied by Hightower: nanothermite produces a blinding flash of light when it goes off. If such immense quantities of nanothermite were used to blow up the Twin Towers, then why didn’t we see tremendous bursts of blinding light all over two those buildings as they were destroyed and largely converted into millions of cubic yards of very fine dust?

The Dangers of a False Theory

Architects & Engineers for 9/11 Truth, which is led by Richard Gage, has been ceaselessly promoting the nanothermite discovery as the “smoking gun” of 9/11, and calling the substance a “high explosive”. If there is ever a

proper investigation and a lawsuit is filed in a court of law on the “strength” of nanothermite as “hard evidence” of controlled demolition by explosives at the World Trade Center and it is revealed to the court by the opposing side that nanothermite is at best a very weak “explosive” and could not possibly have destroyed the Twin Towers in seconds, the entire case would almost certainly be dismissed and a legal precedent set against future efforts by others.

The danger of promoting a false theory or of overselling a weak hypothesis to millions of people is that it may someday be a convenient way to close the book on the entire issue. That 9/11 nanothermite advocates insist on their position in the face of significant refutations is disturbing. They are clearly unwilling to change their minds or even to discuss facts that expose weaknesses in their statements. What do these refusals really mean? Are some leaders deliberately pushing a flimsy theory with the intent that it will ultimately be shot down? Or is nanothermite a red herring or limited hangout to keep us from looking into what was really used?

The 9/11 Truth community can be confident in its refutations of the official account of 9/11 without having to present a “bullet-proof” alternate theory. It may well be that thermite/thermate/nanothermite was used in its familiar role as an incendiary (or “cutter charge”) in destroying the Twin Towers. But that is very different than to claim that it is a “high explosive” that could have destroyed those buildings. The 9/11 Truth movement must not commit itself to a feeble alternative, especially when an honest assessment of the empirical data for that theory does not support its applicability and actually refutes it.

  1. Agreed. It is not all or nothing. Whatever other materials/techniques may have been used to bring down the buildings, thermite is present in all World Trade Center dust. This is incriminating evidence.

    In 2005 James Fetzer and Steven Jones co-founded a group called Scholars for 9/11 Truth. In 2007, Jones and other legitimate scholars formed a splinter group called Scholars for 9/11 Truth and Justice. Here is a link to a Wikipedia Article that explains this division in greater depth:

    In the final analysis, Scholars for 9/11 Truth [SFT] is disinformation, and is not to be confused with splinter group, Scholars for 9/11 Truth & Justice [SFT&J], which is widely respected within the movement.

    To the uninitiated observer, it would seem that there is some deep schism within the 9/11 truth movement, but this schism is actually between the legitimate truth movement, represented by David Ray Griffin, Richard Gage, Steven Jones, Kevin Ryan, Niels Harrit et al.– and the disinformation apparatus represented by James Fetzer, Judy Wood, Gordon Duff, and (maybe) Kevin Barrett (whose writing is often offensive, bordering on anti-Semitic).

    The fundamental disagreement between these two groups is over what role nanothermite played in the demolition of the towers.

    What makes the argument of SFT clearly disingenuous is the fact that at no point do these “scholars” claim that nanothermite was NOT present in WTC dust, because that assertion would be demonstrably false.

    What they claim instead is that other means were likely employed to effect the complete disintegration of Towers 1 and 2– a claim which legitimate 9/11 truth-seekers do not discount. But they couch their argument in language which seems to discount the thermite hypothesis.

    In conclusion, unreacted thermite and iron microspheres are present in all WTC dust samples. This fact alone is more than sufficient to identify 9/11 as a crime very different in nature from that which the mainstream media have thus far portrayed. Other means were likely employed to effect the total and rapid disintegration of the WTC towers, but these means are not yet known to the scientific community, and to introduce controversy surrounding the thermite hypothesis is irrelevent and counterproductive, a distraction from what is known and proven.

  2. Just by looking at how WTC7 fell – like a simple box, straight down with the crushing happening in the basement, how can this be done without explosives/thermite/thermate?

    Did someone remove the buildings feets by magic?

    This is obvious, and you dont have to be an engineer to see that.

  3. It's not all or nothing. Obviously thermite couldn't have been responsible for turning the concrete into dust. However, it was needed to melt the steel allowing for the collapse. There was molten steel at the WTC. Something had to melt it. As far as disintegrating the concrete, it appears to be something exotic because the building just crumbled without obvious large explosions.

  4. If you read the papers written by Dr. Jones, and I have not read all of them word for word, apparently he does not make any strong clear statements about "thermite" or "nanothermite." However he and Richard Gage and others strongly imply, in their speech, that nanothermite is explosive and it is what accounts for what was observed in the destruction of World Trade Center 1, 2, and 7. That mysterious, top secret substance, nanothermite, is also strongly implied to be what brought about "molten metal" and "iron spherules", but again you won't find any unequivocal statements like that in the actual "studies." The "thermite gang" is now strongly implying that what took down World Trade Center 7 is what "took down" World Trade Center Buildings 1 & 2, the "Twin Towers."
    All of this has had a hand-waving, flimflam quality to it from the beginning and I knew it was all about selling us a story rather than doing solid science and speaking about that science honestly. I am thankful to Mr. Hightower for shining the light on all of this from an engineer’s viewpoint. I knew it never made sense, but he has called their bluff and told them to put up or shut up. They have apparently chosen the latter.

  5. This information needs to be known by the 9/11 Truth Movement who believe in nanothermite like it's their religion. Why can't they wake up and think for themselves instead of taking what their leaders say for granted? It's no different from the sheeple out there. I guess there are sheeple everywhere, in all groups.

  6. I have always considered the thermite explanation to be a fairy tale. Every video that I have seen of a thermite experiment has a huge amount energy released as visible light… and we didn't see that, at all, on 9/11.
    Also, how does nano-thermite explain the "spire event"?
