.........The only way to keep things hot for weeks is by adding heat continuously. Molten steel would solidify fairly quickly no matter how it was melted unless heat were added. Underground fires can get exceptionally hot. There were large amounts of wood, plastic, and paper in the rubble which could have provided the heat.

Re: Public Comments on WTC 7 Draft Reports
Dear Mr. Cauffman,
in NIST’s "Questions and Answers" page (www.nist.gov...), NIST has attempted to refute many of the points that members of our group and others have made regarding the WTC 7 destruction. However, NIST did not provide any references to sections of the Report that support its alleged refutations. How is a member of the public, then, able to verify NIST’s refutation without reading through the entire 1000+ page Report? Our comments are directed to many of the areas addressed in the "Questions and Answers" page, and without citations directly to the Report itself, it was extremely difficult and time consuming for us see whether our main criticisms of the NIST theory of collapse have been adequately addressed in the Report. This is especially true in light of the fact that this latest draft Report is the third different story NIST has come up with.
Your response to our request was dismissive, based primarily on your belief that a six-week comment period on the 10,000 page report NIST issued for the Twin Towers was reasonable. You also saw no problem with NIST’s failure to provide any references in its Questions and Answers page to the 1000 page Report itself, apparently satisfied with NIST committing the logical fallacy of appeal to authority. As things stand right now, your position in this matter can be seen as nothing less than a deliberate attempt to hamstring the public’s ability to review and comment on NIST’s work in this extremely important area of research.
Nevertheless, we have been able to spend some time reading and analyzing the report, and have already found numerous problems that severely undermine its veracity and usefulness. Our comments on the Report are detailed below. Note that we declined NIST’s invitation to comment only on the summary report, NCSTAR 1A. These comments are all regarding the more detailed NCSTAR 1-9 document. Of course, once NCSTAR 1-9 is revised according to these comments, the summary report NCSTAR 1A will need to be revised as well.
Why hasn't the "future research" been done, and the results from it published, especially when FEMA itself suggested that this melting and erosion may have started “prior to collapse”? NIST was charged with investigating the conditions that led to the collapse of WTC 7, and clearly something that possibly occurred prior to collapse and “accelerated the weakening of the steel structure” is something NIST should have investigated. NIST should revise the Report accordingly after it has performed the needed metallurgical analysis.
Rebuttals are not peer reviewed. In this case there is no science to stand. This "science" is laying down and unconscious. It only convinces web browser scientists of its veracity and rigor because their understanding of it is superficial.

8. You ignore the science again. Normal office fires are not hot enough to melt steel,let alone turn steel into swiss cheese and then be ignored by NIST. That's why it was the greatest mystery of all according to NYTimes."
....This was not a normal office fire. It was an underground fire insulated by concrete rubble that burned for weeks. Slow burning, insulated fires can get very hot.
9. Please source public comments about WTC 7 from other Controlled Demolition Companies to help further my knowledge base. TYVM."
..........I think it was Loizeaux from Controlled Demolition who made the comments.
With regards to 7:
11. ...........They apparently wanted to ignore this point. Maybe they have no real explanation. I doubt that the steel "evaporated." Maybe corroded or eroded but not evaporated.
"Dr. Barnett, a professor of fire protection engineering at the Worcester Polytechnic Institute:
A combination of an uncontrolled fire and the structural damage might have been able to bring the building down, some engineers said. But that would not explain steel members in the debris pile that appear to have been partly evaporated in extraordinarily high temperatures, Dr. Barnett said.
What demolition experts say about 9/11: is there evidence that explosives caused the collapse of the World Trade Center buildings as many conspiracy theorists claim?
Blanchard and his experts at Protec are uniquely positioned to address concerns that explosives may have been used to bring down the World Trade Center buildings. They have worked with all major American demolition companies and many foreign ones to study the controlled demolition of over 1000 of some of the largest and tallest buildings around the world. Their duties include engineering studies, structural analysis, vibration/air overpressure monitoring and photographic services.

Eyewitness Reports Persist Of
Bombs At WTC Collapse
By Christopher Bollyn
Exclusive to American Free Press
Van Romero, an explosives expert and former director of the Energetic Materials Research and Testing Center at New Mexico Tech, said on Sept. 11, "My opinion is, based on the videotapes, that after the airplanes hit the World Trade Center there were some explosive devices inside the buildings that caused the towers to collapse."
Evaporation of steel takes very high temperatures. I haven't bothered to look up vapor pressure curves but if Dr. Barnett said "evaporated" and you back him, who am I to quibble.
Note also that there may be two distinct events. Eroded/evaporated steel may have occurred after the collapse and not caused the collapse..which the engineers stated "A combination of an uncontrolled fire and the structural damage might have been able to bring the building down, some engineers said."

Simulations do not offer "raw facts;" they offer calculations based on a model.
Introduction
The Model
The structure of each tower can be visualised with 3 basic elements:
* The Exterior Walls - A square tube forming the outside of the building, running from the bedrock base to the roof.
* The Central Core - A rectangular tube in the centre of the exterior wall 'tube', also running from the bedrock base to the roof.
* The Floors - A thin horizontal slab forming each floor of the towers, attached to the Exterior Walls and Central Core.
The Twin Towers were each 110 storeys high, above ground, plus a further 6 underground storeys.
The Exterior Walls were constructed from 236 vertical steel box columns around the perimeter of the 'tube', with each column being attached to the next by massive horizontal spandrel plates at each floor level forming a dense 'mesh', and with windows filling the space between each column.
The Central Core was constructed from 47 massive vertical steel box columns, with the space inside the core area housing building facilities such as lifts, staircases and tenant storage.
The Floors were constructed as trussed steel meshes bonded with a 4 inch thick layer of lightweight concrete, forming large open-plan tenant space between the Central Core and the Exterior Walls.
The WTC Collapse Simulator Model (The Model) simplifies these basic elements even further.
The Model can be visualised simply as 110 stacked 'Storeys'.
Each Storey comprises the whole of the Exterior Walls, Central Core, Floor and contents for the entire tower structure between one Floor and the next above, including the Floor Slab itself and the physical contents of each floor.
The Model essentially calculates the energy required and expended by the destruction of each subsequent Storey within the progression of any modelled collapse.
The calculations are performed Storey by Storey taking account of the dynamic nature of the collapse, and includes many adjustable Parameters.
Specific attention is focussed on the determination of the effect each Parameter and data change has upon the time that the collapse progresses in.
Each Parameter and all calculations are detailed in full, and the provided source data fully explained.
All data within the model can be changed by the user, enabling open and interactive experimentation.
The Simulator
The Simulator is comprised of two components: * The Calculations - A spreadsheet containing all data, calculations and parameters required to calculate a simple Storey by Storey collapse timing, along with detailed calculation of the energetics involved.
* The Visualiser - An OpenGL based application which allows the user to visualise the collapse in real-time, at any point in time, and from any viewpoint, using the data calculated in The Calculations.
This allows the user to quickly see the effect that changing various parameters has upon the collapse time.
These Parameters include:
* Whether the Central Core and Exterior Walls pose any resistance to the collapse.
* Whether crushing the concrete in The Floors requires any energy.
* How much mass is ejected from the sides of the Tower.
By understanding the effect of these parameters upon the collapse time and energetics, and experimenting with multiple options, the user should be able to reach an informed personal opinion.

"If the 110-story Twin Towers had fallen over, they would have caused an enormous amount of damage to buildings covering many city blocks. But the towers came straight down. Accordingly, the official theory, by implying that fire-produced collapses that perfectly mimicked the collapses that have otherwise been produced only by precisely placed explosives, requires a miracle."
"With the use of delays, we can control pretty much where the debris lands; we can control vibration; we can control noise levels. Timing and delays are the keys to just about everything in our business."

"This whole entire post is based on your opinion only."
........but it is a highly educated opinion. Apparently, you have no opinions of your own and no skills to generate them. Do webonauts check blogs each morning to find out what they are to think for the "whole entire" day?
"Uneducated so much that either you don't understand or can't comprehend that architects and engineers who build these buildings know full well that 3 WTC buildings could not have fallen due to some simple fires with minor damage. That is just completely false and purposeful deception on your part."
...............They KNOW nothing of the sort. They designed the buildings to be safe but that doesn't mean that the failure is proof of sabotage. It could mean that the design wasn't what they thought it was or that they had not allowed for the extreme conditions that occurred. Cars are designed so that people survive in collisions. Did everyone in a collision last week survive?
"In all the likely variations of an accidental impact with the WTC, the Boeing 707 would be traveling faster. In terms of impact damage, this higher speed would more than compensate for the slightly lower weight of the Boeing 707.
In conclusion we can say that if the twin towers were designed to survive the impact of a Boeing 707, then they were necessarily designed to survive the impact of a Boeing 767."
....But that doesn't mean that they would in either case. Theory and experiment are not the same thing, are they? The "likely variations" were with fuel tanks nearly empty and at approach speed, not suicidal maniacs with full fuel tanks going as fast as possible. Maybe that omission is a completely false and purposeful deception on your part.
"A liquid does not become pressurized when it impacts something. If you take a cup of water and throw the water against a wall, it is not becoming pressurized. That is just simply your misunderstanding of what pressurizing something is, and/or you're making things up to explain away the facts so that you don't have to believe in the "conspiracy"."
..........A liquid in a closed container does. As the container collapses, there is less volume and more internal pressure until the container fails. Think about it.
.....Did Lozieux happen to mention what else had to be done to demolish a building and how long it took to prepare even the smallest building? His statement also says no thermite, which is what Jones says was the culprit. How will we reconcile that?
"I'd like to see your paper or a source showing how Dr. Jones' protocols are faulty. Until then, you're above attack only makes you look like an opinionated and biased fool."
.....People in Hell would like icewater, too. You still don't understand the simple explanations I have given many times over. Of course, not being technically trained, you demand references from other websites that you think are necessary for me to make such statements. My source is my education and experience. Jones is either incompetent or a fraud. I believe that he desires public vindication after his university canned him and he sees this as one way to get it. That said, I think he believes what he claims but doesn't know enough to realize that by running the DSC in air, he hasn't shown anything except that some things burn. You did get that part, didn't you?
My statements are there for anyone to debate. You are welcome to comment, technically, if you wish. Is it possible that because you insist on a conspiracy with absolutely no evidence to back it up, perhaps it is you who looks like an opinionated and biased fool?

"You are correct, failure doesn't mean proof of sabotage. But architects and engineers have a good understanding of what does and does not cause buildings to fail. Otherwise, we wouldn't be able to have buildings built to withstand earthquakes, for instance. Architects and engineers know how buildings fail in earthquakes and we now have earthquake-resistant buildings. They also know how fire reacts to buildings and hundreds of them are saying they don't think fire brought down 3 WTC buildings on 9/11."
............And thousands think the aircraft and fires did. Architects and engineers designed those buildings almost 40 years ago and did what they could with what they had. They NOW know why buildings fail in earthquakes and TRY to make them as resistant as possible.
"The fuel tanks on the planes that hit the towers were not anywhere near full. The FEMA report estimates that about 10,000 gallons of fuel was onboard the jets. That's less than half of what the 767-200's can carry.
Frank DeMartini, WTC construction manager said the buildings were designed to have a "full loaded" jetliner crash into them. "Fully loaded" means fuel, passengers, luggage, etc. I said this in my last post that you quoted from. I don't understand why this is so hard to understand."
Either way, your comment about "suicidal maniacs with full fuel tanks" is absolutely false either from lack of research or purposeful deception.
..........Are you saying that the buildings were designed for suicide attempts in aircraft travelling at top speed? Are you saying that in the 1970's this was anticipated and that the designs of the time were sufficient to survive the impact of a 767 despite the fact that there was absolutely no precedent for such a design? I'm sure the intent of the design was to survive an aircraft impact but apparently it wasn't able to. Firemen were unable to get above the impact floors and people were unable to get below. Water was not available to extinguish the fires. Does that sound like a successsful design to you?
"I don't know where you're getting Loizeaux saying no thermite, especially when you once again provide no source. And you're obviously not understanding Dr. Jones' work or the work of AE911T. Thermite may have been used to aid in collapse initiation, but the collapses themselves were of mostly conventional demolition explosives. In otherwords, whoever says that only thermite was used, doesn't know what they're talking about."
........You are fixated on web sources, aren't you. They are all trustworthy, of course. Step away from the mouse and activate your brain.
Thermite cannot be timed for a demolition. Heat flows relatively slowly and failure is less predictable that a cutter charge. If you had super silent explosives that you would set off in a top down mode, why would you even need thermite? If thermite would do what you think, why do people use explosive charges at all? Timing is the Lozieux bread and butter. Of course, setting such charges and precutting structural members while no one noticed is a bit of a problem for this theory. Knowing what floor the aircraft would hit is another little problem for the demolishers. This coupled with the unfortunate lack of ANY evidence of demolition leads one to believe that there was no demolition, as much as some souls really crave one.
"You yet again use blatantly false information to try to make your point. This isn't the first time you've said that Jones was fired from BYU. Since I corrected you before with a source and you still are saying he was fired, then you are showing yourself to be a true disinfo artist that does not care about truth at all.
Dr. Jones elected to retire effective January 1, 2007:
en.wikipedia.org...
You have no credibility. Not one single person is going to take you seriously if you can't be honest and truthful."
.........I amend my statement. Jones retired. I believe he retired under significant pressure from the University, but I will accept "retirement."
"Since I've shown that you don't have an ounce of honesty in you, your opinions based on your education and experience mean absolutely zilch. Therefore, we require sources from someone that is not you. So once again, please provide sources for your claims."
.........I do not believe that you've shown any such thing. What I said is correct and can be verified by any chemist. I must first ask who is "we." Mark Twain said that the only people who should use first person plural are heads of state, royalty, and people with tapeworms.
My claims of bad science may be argued by any competent chemist. There is no paper out there that says "when proving an exothermic reaction that doesn't use air, don't be dumb enough to run it in air." Do you actually think that there is a youtube video explaining all of this?
Find a competent chemist. Ask them what happens to carbonaceous material when it is a DSC sample in a flow of air. Ask them if those conditions would prove or mask thermitic materials. You don't even need to be a chemist to understand how Jones blew this analysis. This is really basic stuff and any competent chemist can tell you that the combustion hides any possible thermitic reaction and all it means is that carbon burns.
Of course, the conclusions in the paper are invalid because of this error. Jones proved nothing other than the carbonaceous matrix burns.

Okay, I would love for you to produce a list of "thousands" of architects and engineers that think the aircraft impact and fires caused the buildings to collapse. I've asked for this many times before to no avail. I'm pretty sure you won't be able to produce the list either. Especially with your history of not being truthful or supplying sources to support your claims.
Another interesting fact is how empty the 4 planes were. I have never been on a plane that is 75% empty!! So many inconsistencies!!
It doesn't make sense that fires from jet fuel could melt structural steel, let alone in sufficient quantity to collapse both towers.
Columns cut with clean distinctive angle by what plane wing, god?
The evidence proves that there is no way that ANYONE could have used cell phones to call people from those planes.
2) the free fall of the Towers in less than 10 seconds.
The towers asbestos related non-compliance problem should be sufficient reason alone to investigate the event as towers owners’ criminal act as well as an insurance fraud, due to the billion dollar cost to make the twin towers to comply.
After performing some in-depth research on this subject, I have come to the conclusion that no commercial airplanes impacted the two WTC Towers.
1. WTC 1 & 2 collapse at or above free fall speed.

• Personal 9/11 Statement:
After performing some in-depth research on this subject, I have come to the conclusion that no commercial airplanes impacted the two WTC Towers. No commercial plane impacted the Pentagon. No commercial aircraft buried itself in Pennsylvania terra firma. The utter public silence from observing the many clips of high energy materials being ejected from the other side of WTC #2, from most probably a projectile with DU-hardening nose characteristics is deafening. Further, The two WTC Towers were explosive demolitions, without any doubts. WTC #7 crumbled under a classic demolition. Lastly, a 0.1 inch aluminum skinned airframe travelling at its max. velocity for its flight regime and angle of attack, would NOT slice through high tensile steel like butter with this steel having a thickness between 0.25 and 0.75 inch and a length of about 13 inches. Calculations from other sources reveal that the airframe would lose its forward momentum when impacting steel of only 0.8 inches. If these projectiles were commercial aircraft, we should have seen the entire impact explosion of the airframe only at the impact wall with discernable debris landing at the base of each Tower.
