Hey Red, what do you think of the post by Mackey that you called 'helpful'? Could you address it?
Thanks!
Thanks!
Welcome to the site, sdemetri
So subterranean fires at Centralia are irrelevant to understanding what happened in the subterranean pile, but large structural fires are very relevant? Is that your claim?
“You said, “The "explosions followed by white dust clouds" are, of course, gypsum, concrete, and similar materials ejected by the collapse, and not by a "thermite reaction." “
NIST comments on the white clouds as “An unusual flame is visible within this fire. In the upper photograph {Fig 9-44} a very bright flame, as opposed to the typical yellow or orange surrounding flames, which is generating a plume of white smoke, stands out." Source: NCSTAR 1-5A Chapter 9 Appendix C NIST Fig. 9-44. p. 344
Source: nist factsheets/faqs_8_2006 (August 2006)”
Curious that you are simply reciting one of Jones’ own claims that concerned an alleged plume of smoke from the upper stories of the WTC long before the collapse. What exactly does this have to do with what was happening in the pile weeks or months later?
It is pretty easy to take stills from the video of the North Tower, establish a point on the communications tower and on the roof line and plot a curve of their acceleration into the rest of the building, a presumably intact building below the damage zone. The pixels in the still frames make for a very accurate way to measure the drop as they can be converted to feet relatively easily. As the frames of video are captured at regular intervals, the drop verses time makes for a very accurate curve.
The North Tower communications tower and roof line accelerated into the lower building. There is no deceleration. Why? Because the building is disintegrating out from under the upper block. There was no deceleration, the block accelerated through what was below it. How else can that lack of resistance be explained except by removing what would cause resistance from below. And that is consistent with account after account of firefighters hearing and seeing large explosions just prior to the upper block falling. With nothing to slow the fall of the upper block, that mass of material accelerated into the rest of the building. At no point is there deceleration witnessed in what is available in the mechanical evidence before the entire collapse becomes obscured in a semi-gaseous cloud of pulverized concrete and office materials.

The point of the paper, at least one point, is to highlight the fact that neither Cahill nor EPA could explain to spikes in VOC. They were atypical. They were not expected in very large structural fires, another very unexpected occurrance in what were very unexpected collapses. The evidence for high temperatures in volatized metals is completely unexpected and in need of explanation. As Cahill said, "they should not have been there..." and he and apparently no one else has any explanation for it. Highly energetic nanocomposites provide an explanation that is very consistent with many other aspects of the evidence. It plausibly explains USGS's finding of molybdenum microspheres, RJ Lee's findings of volatized lead, and aluminosilicates, Worcester Polytech's findings of volatized steel. The typical large structure fire does not explain these phenomena.
The formation of iron-rich microspheres below the m.p. of pure iron at ~ 1537 deg C is a complex process but is possible in an environment containing HCl/Cl2 and SO2/SO3 in the presence of O2 and H2O. Iron is transported as a volatile di or tri-chloride. FeCl2 has a m.p. of 677 deg C and allows "active" corrosion to occur with iron wastage rates as high as 100 g/m^2 per hour. The iron chloride is relatively unstable and decomposes but the iron does not wind up as a pure iron microsphere. As the very least it will be oxide (probably Fe3O4) coated and alloyed with other metals such as Al. Fly ash usually contains mullite, Al6Si2O13. This readily combines with iron oxide at ~ 1000 deg C to form an iron-rich aluminosilicate microsphere on cooling. Other elements such as K and Ca are also readily incorporated into these melts. This is the chemistry of CLAY minerals! As long as Jones' microspheres contain Si and/or K and Ca, they are NOT derived from thermite.
Could you provide information on the "levels ... recorded"? I thought in one of these discussions it was said that the topic had hardly been studied anywhere. That would mean that your implied criticism, above, isn't valid.
I did address it. I found it helpful. His theory that the fuel for the spikes was contained in the basements, essentially office contents, does not account for the levels recorded, nor does it account for the fact that the greatest spike occurred long after this material would have been removed.
Both.
Molybdenum is a component of structural steel, the fact that microspheres of such existed have many explanations besides thermite. Welding, for example.
The lead can have very mundane origins. Uninterruptible power supply batteries, for example.
And the argument about a "typical large structure fire" is a red herring. That doesn't matter considering that the World Trade Center events are unique in many regards.
How many large structures have had fires that large? Some "large structures" that were completely aflame probably didn't suffer the same size of conflageration that the Twin Towers did.
And to get to the heart of the argument: How do we know that the VOC emissions are indeed unusual?
(let's call a spade a spade and stop trying to disguise thermite as "highly energetic nanoparticles". That fools no one)
And again, it's very, very unlikely as a cause given that there was practically zero opportunity for it to be emplaced.
Well there you go. Thanks for using those quotes. It removes all doubt that you cherry pick evidence, or worse, are not above lying to push your agenda....a chief saying, "two small pockets... two lines to take it down..."

Thank you for finally proving that you have zero idea of what you're talking about. If you had done anything close to research, you would have known that the firemen were at the 78th floor when they made that statement. That is 2 floors below the main crash site and fire. IIRC, fire generally does not travel down a building.You mean the conflagration MIT's Eagar said was "not unusual." You mean the conflagration hundreds of firefighters went up into the buildings, one of them, a chief saying, "two small pockets... two lines to take it down..." The fires were not that large, and other large structure fires the EPA has monitored have not shown the same VOC releases that these did, in a pattern that in any way resembles the releases recorded here. You haven't made much of an argument.
How many of the other large structural fires involved most of the flammable material being compressed by several hundred thousand tons of debris?:52 a.m.
Battalion Seven Chief: "Battalion Seven to Battalion Seven Alpha."
"Freddie, come on over. Freddie, come on over by us."
Battalion Seven Chief: "Battalion Seven ... Ladder 15, we've got two isolated pockets of fire. We should be able to knock it down with two lines. Radio that, 78th floor numerous 10-45 Code Ones."
Ladder 15: "What stair are you in, Orio?"
Battalion Seven Aide: "Seven Alpha to lobby command post."
Ladder Fifteen: "Fifteen to Battalion Seven."
Battalion Seven Chief: "... Ladder 15."
Ladder 15: "Chief, what stair you in?"
Battalion Seven Chief: "South stairway Adam, South Tower."
Ladder 15: "Floor 78?"
Battalion Seven Chief: "Ten-four, numerous civilians, we gonna need two engines up here."
Ladder 15: "Alright ten-four, we're on our way."

You mean the conflagration hundreds of firefighters went up into the buildings to fight, one of them, a chief saying, "two small pockets... two lines to take it down..."

The "retardation" of the upper block looks alot to me like "deceleration" of which we see none. I was trained as a chemist, not an engineer. It seems this hypothesis, crush up/ crush down, has been forwarded to try to explain progressive collapse, but acceleration occurs with a lack of resistance. Opposing forces require some resistance; one is either stronger than the other, or they perfectly cancel out. The mass of the upper block was not so great as to provide an overriding force that would destroy the material below it before it arrives, therefore accelerating through it. That makes no sense to me...
You said the collapse was chaotic. The repeated symmetry seen in many stills and video does not seem at all chaotic. Corner assemblies remain intact while a straight, not chaotic, destruction front blows out windows, from one corner to the other simultaneously, floor by floor. It is very regular, very symetrical. There is symetry in the plumes of debris at collapse initiation, while the upper mass accelerates down. The symetry is very close to the same for both buildings, although each building had unique damage.
Worcester also said what they found was entirely surprising. And what they found was evaporated steel, holes in flanges thinning down to sharp edges. Completely unexpected and unexplained, in spite of the eutectic reactions they also found evidence of. Careful you don't try to explain for them what they found.
R Mackey, regarding an earlier post …
In fact, the un-extinguishable fires have NOT been adequately explained. Not in any study by NIST, FEMA, USGS, RJ Lee, Worcester Polytech, any other study, that I am aware of, that has been officially commissioned or carried out. NIST denies that there even were fires.
Comparing the WTC fires to the Centralia underground fire is completely irrelevant as the two have nothing in common, or any connections whatsoever. That Centralia took place doesn’t explain, adequately or not, what generated the WTC fires, or sustained them. The Centralia fire has a natural fuel source, the WTC fires had an undetermined fuel source.
That the official studies have not addressed the fires at the WTC piles is, in fact, very relevant to the statement by Ryan that they “have not been adequately explained…” If they have been adequately explained, cite your documentation. A casual reference to a known underground fire proves absolutely nothing.
This paper assumes there is much plastic, polyvinyl chloride, computer housings, office materials in the rubble. It is the release of particulate matter, and the documentation that shows typical release patterns of PM in large structural fires, as well as the concentrations of specific compounds that EPA and Cahill reported, that are not adequately explained by what is known about large structural fires.
The paper states: “The spikes in VOC detection could also be explained as a result of rapid combustion of typical materials found within a building structure. If energetic nanocomposite materials, buried with the pile at GZ, were somehow ignited on specific dates, violent, shortlived, and possibly explosive fires would result. Such fires would have quickly consumed all combustible materials nearby. The combustible materials available, after a month or two of smoldering fires in the pile, might have been more likely to be those that were less likely to have burned completely on earlier dates, like plastics. Later combustion of such plastic materials, in violent but short-lived fires, could explain the spikes in VOC’s seen on those dates.”
Cahill attempts to discuss the aberrant findings, but with hypotheses that don’t seem very likely. Many of the aberrant findings, “very fine aerosols typical of combustion temperatures far higher than [expected in] the WTC collapses piles… some elements abundantly and others hardly at all, despite similar abundances in the collapse dust…organic species in the very fine mode that would not survive high temperatures…” which organic species included sulphur and sulphur-based compounds and fine particles of chemically bound silicon, in their abundance are not easily explained by what is typical of large structural fires. Cahill attempted to ditch the “high temperature” explanation in favor of volatized metals due to high concentrations of chlorine, not a likely scenario. High temperatures do easily explain volatized metals, and is corroborated by the USGS, RJ Lee, and Worcester Polytech findings of extreme temperatures.
They likewise found evidence of extreme temperatures and volatized metals. Sulphur and sulphur-based compounds, silicon, and other volatized metals are consistent with nanocomposite energetic materials, but not easily explained in their concentrations and release patterns by typical structural fires. Cahill said in relation to some of the PM, “these particles simply should not be there…”
You said, “The "explosions followed by white dust clouds" are, of course, gypsum, concrete, and similar materials ejected by the collapse, and not by a "thermite reaction." “
NIST comments on the white clouds as “An unusual flame is visible within this fire. In the upper photograph {Fig 9-44} a very bright flame, as opposed to the typical yellow or orange surrounding flames, which is generating a plume of white smoke, stands out." Source: NCSTAR 1-5A Chapter 9 Appendix C NIST Fig. 9-44. p. 344
So, not “of course, gypsum or concrete…” white smoke… consistent with a thermite/thermate incendiary device. Your dismissal of what NIST calls “white smoke” generated by an “unusual” and “bright flame,” as gypsum or concrete is unsubstantiated. Thermate burns with a very bright flame and gives off a plume of white smoke consisting of aluminum oxide, which is consistent with the flame and white plume NIST comments on.
Ryan doesn’t make a case for “persistent thermite reactions.” The very quick, energetic exothermic reaction is over very rapidly. In the event an excess was used to sever connections in the perimeter and core columns, which is entirely consistent with the lack of resistance to the collapse once it initiated, it is highly plausible pockets of un-ignited thermite/thermate existed in the pile. At any rate, there is sufficient cause to investigate incendiaries.
None of you here have made any case whatsoever against conducting an investigation into that possibility. The most you have done in this thread is thumping of chests, patting each other on the back, and name calling, with poor or no substantiation to your arguments.
180,000ppb is a massive amount of benzene to be suddenly released, as are daily averages of 18,000 ppb. It warrants investigation. Especially in light of the EPA’s failure to warn workers and others of the environmental dangers to working in the area at the time, and in light of the sicknesses and deaths that are occurring in first responders.
I did address it. I found it helpful. His theory that the fuel for the spikes was contained in the basements, essentially office contents, does not account for the levels recorded, nor does it account for the fact that the greatest spike occurred long after this material would have been removed.
