Give this man a medal. In just two minutes, blacksmith Trenton Tye of Purgatory Ironworks uses science to hilarious effect to mock 9/11 truthers who insist the 2001 terrorist attacks were a conspiracy. And why are these nutters convinced the whole thing was an inside job? Because fire can’t melt steel (Seriously, read through that entire 9/11 conspiracy theory thread. It is amazing.) Tye, a professional metalworker based in Georgia, has had enough. He filmed the following video to prove to science-hating 9/11 conspiracy mongers once and for all that structural steel will absolutely lose its structural integrity if it gets too hot: “So I am taking time out of my busy day to try to put to rest one of the more moronic things I have seen on the Internet lately, and that’s saying something,” Tye tells the camera. “‘Jet fuel only burns at 1,500 degrees and since steel melts at 2,700 degrees, 9/11 was a conspiracy!'” “What I am upset about is the retarded metallurgical things that you guys are saying. I’m not arguing the facts,” Tye says. “Jet fuel does in fact burn at 1,500 degrees. Some carbon steels will start melting at 2,300 degrees. But if you hold this up as a reason for conspiracy, you are an idiot!” To prove his point, Tye compared the structural strength of a room-temperature piece of steel to the strength of one that had been heated to 1,800 degrees in his workshop’s furnace. “It’s very hot, but not melted,” Tye notes by tapping the piece of steel on an anvil. “Half-inch solid steel. Check it out,” Tye says as he bends the solid steel rod back and forth using only his pinkie finger. “It’s a freakin’ noodle!” “Your argument is invalid. Get over it!” Tye exclaims as he drops the mic by dropping the glowing steel rod. “Find a job!” We salute you, Trenton Tye. You are a real American hero. Godspeed.

Exactly so. I've read some very strange Truther articles on how steel spreads and dissipates heat miraculously. But anyone who has worked with a torch knows better. It conducts some heat but not very effectively. A torch could never be effective at cutting steel if it was as conductive as the Truthers believe.
Just curious, have you read any of the official NIST reports on the Twin Towers? http://www.nist.gov/manuscript-publication-search.cfm?pub_id=909017 Obviously few have. It's hilarious to watch the nonsense spew like a busted fire hydrant.
If there is a point of weakness in the middle. The base is still solid. It should fall over because there is resistaqnce straight down but none if it were to fall over.
Someone gave me a copy of the 9/11 Commission report for X-mas one year. I thought it was too dull to read. I think I still have it somewhere but have no more interest in reading it now than I did then. I never click any .gov link. Well, almost never.
I'm not going to go there. You win. Okay?
That is just what it seems like to me. I'm not an expert. I could be wrong. Who knows.
The pancake theory was proven to defy the laws of physics and was officially rejected by the officials reports from the U.S. government. It is impossible to pancake the floors and get them to the ground in the amount of time observed and documented. This does not indicate I accept the NIST theory, just that the original pancake theory had to be abandoned as proven impossible. http://wtc.nist.gov/pubs/factsheets/faqs_8_2006.htm Answers to Frequently Asked Questions (NIST NCSTAR throughout this document refers to one of the 43 volumes that comprise NIST’s final report on the WTC Towers issued in October 2005. All sections of the report listed in this document are available at http://wtc.nist.gov.) [...] 2. Why did NIST not consider a “controlled demolition” hypothesis with matching computer modeling and explanation as it did for the “pancake theory” hypothesis? A key critique of NIST’s work lies in the complete lack of analysis supporting a “progressive collapse” after the point of collapse initiation and the lack of consideration given to a controlled demolition hypothesis. NIST conducted an extremely thorough three-year investigation into what caused the WTC towers to collapse, as explained in NIST’s dedicated Web site, http://wtc.nist.gov. This included consideration of a number of hypotheses for the collapses of the towers. Some 200 technical experts—including about 85 career NIST experts and 125 leading experts from the private sector and academia—reviewed tens of thousands of documents, interviewed more than 1,000 people, reviewed 7,000 segments of video footage and 7,000 photographs, analyzed 236 pieces of steel from the wreckage, performed laboratory tests and sophisticated computer simulations of the sequence of events that occurred from the moment the aircraft struck the towers until they began to collapse. Based on this comprehensive investigation, NIST concluded that the WTC towers collapsed because: (1) the impact of the planes severed and damaged support columns, dislodged fireproofing insulation coating the steel floor trusses and steel columns, and widely dispersed jet fuel over multiple floors; and (2) the subsequent unusually large jet-fuel ignited multi-floor fires (which reached temperatures as high as 1,000 degrees Celsius) significantly weakened the floors and columns with dislodged fireproofing to the point where floors sagged and pulled inward on the perimeter columns. This led to the inward bowing of the perimeter columns and failure of the south face of WTC 1 and the east face of WTC 2, initiating the collapse of each of the towers. Both photographic and video evidence—as well as accounts from the New York Police Department aviation unit during a half-hour period prior to collapse—support this sequence for each tower. NIST’s findings do not support the “pancake theory” of collapse, which is premised on a progressive failure of the floor systems in the WTC towers (the composite floor system—that connected the core columns and the perimeter columns— consisted of a grid of steel “trusses” integrated with a concrete slab; see diagram below). Instead, the NIST investigation showed conclusively that the failure of the inwardly bowed perimeter columns initiated collapse and that the occurrence of this inward bowing required the sagging floors to remain connected to the columns and pull the columns inwards. Thus, the floors did not fail progressively to cause a pancaking phenomenon.
You've watched too many Roadrunner cartoons. You thought they were going to tip over like the Tower of Pisa? Give me a break.
7WTC collapse was admitted to have been proven to have achieved gravitational acceleration for over two seconds. That is a physical impossibility if pancaking is occurring. The is no official theory of the collapse mechanism of 7WTC. The official theory goes to the point of collapse initiation, states that collapse was inevitable at that point. The end. And it took something like 6 or 7 years to say that much.
Steel will melt if heated enough and weaken before it melts. However, it was impossible for the available flammables to produce the needed temperature to melt steel, or to weaken 110 stories of huge steel beams. http://www.nist.gov/customcf/get_pdf.cfm?pub_id=101016 NIST NCSTAR1-3 Federal Building and Fire Safety Investigtation of the World Trade Center Disaster Mechanical and Metallurgical Snalysis of Structural Steel Executive Summary page xli The scientific evidence is not very amenable to melting or weakening the steel beams by fire. Other forensic evidence indicates that the last example probably occurred in the debris pile after collapse. Annealing studies on recovered steels established the set of time and temperature conditions necessary to alter the steel microstructure. Based on the pre-collapse photographic evidence, the microstructures of steels known to have been exposed to fire were characterized. These microstructures show no evidence of exposure to temperatures above 600°C for any significant time. Similar results, i.e., limited exposure if any above 250 °C, were found for the two core columns recovered from the fire-affected floors of the towers, which had adequate paint for analysis.
Except for the collapse time defying the laws of physics if it were pancaking floors. That is why the pancake theory had to be officially abandoned.
NIST admits almost 4 seconds. The only way for that to happen is if there's nothing underneath. Part 2 and 3 at Youtube NIST.GOV: Questions and Answers about the NIST WTC 7 Investigation (09/17/2010, ARCHIVE, incorporated into 9/19/2011 update) In a video, it appears that WTC 7 is descending in free fall, something that would not occur in the structural collapse that you describe. How can you ignore basic laws of physics? In the draft WTC 7 report (released Aug. 21, 2008; available at http://wtc.nist.gov/media/NIST_NCSTAR_1A_for_public_comment.pdf), NIST stated that the north face of the building descended 18 stories (the portion of the collapse visible in the video) in 5.4 seconds, based on video analysis of the building collapse. This time period is 40 percent longer than the 3.9 seconds this process would have taken if the north face of the building had descended solely under free fall conditions. During the public comment period on the draft report, NIST was asked to confirm this time difference and define the reasons for it in greater detail. To further clarify the descent of the north face, NIST recorded the downward displacement of a point near the center of the roofline from first movement until the north face was no longer visible in the video. Numerical analyses were conducted to calculate the velocity and acceleration of the roofline point from the time-dependent displacement data. The instant at which vertical motion of the roofline first occurred was determined by tracking the numerical value of the brightness of a pixel (a single element in the video image) at the roofline. This pixel became brighter as the roofline began to descend because the color of the pixel started to change from that of the building façade to the lighter color of the sky. The approach taken by NIST is summarized in Section 3.6 of the final summary report, NCSTAR 1A (released Nov. 20, 2008; available at http://wtc.nist.gov/NCSTAR1/PDF/NCSTAR%201A.pdf) and detailed in Section 12.5.3 of NIST NCSTAR 1-9 (available at http://wtc.nist.gov/NCSTAR1/PDF/NCSTAR%201-9%20Vol%202.pdf). The analyses of the video (both the estimation of the instant the roofline began to descend and the calculated velocity and acceleration of a point on the roofline) revealed three distinct stages characterizing the 5.4 seconds of collapse: Stage 1 (0 to 1.75 seconds): acceleration less than that of gravity (i.e., slower than free fall). This analysis showed that the 40 percent longer descent time—compared to the 3.9 second free fall time—was due primarily to Stage 1, which corresponded to the buckling of the exterior columns in the lower stories of the north face. During Stage 2, the north face descended essentially in free fall, indicating negligible support from the structure below. This is consistent with the structural analysis model which showed the exterior columns buckling and losing their capacity to support the loads from the structure above. In Stage 3, the acceleration decreased as the upper portion of the north face encountered increased resistance from the collapsed structure and the debris pile below. http://www.nist.gov/public_affairs/factsheet/wtc_qa_082108.cfm Almost no one has read the official docs.
Bingo. And, at the lower floors, the steel was bigger and stronger. I note that this does not explain what did happen, only something that did not happen.
Not surprised. You're "too busy". ROFL Let those who have actually read the material try to figure it out. You've got better things to do. Of course not.
Gravity doesn't go sideways ... the fire was internal - Straight down --- it's called reality !
If you ... don't use exclamation points --- you should't be typeing ! Commas - semicolons - question marks are for girlie boys !
Free fall from the 1.75 second mark until the 4 second mark is 2.25 seconds of free fall. Collapse at gravitational acceleration is incompatible with the pancaking of floors, whether it be for 2 or 4 seconds. I should make clear that I know of nothing that fully explains the observed phenomena with all the buildings.
The cumulative falling ... weight - force increases --- so what ! There was one corner of a building stairwell where there were survivors ! If you ... don't use exclamation points --- you should't be typeing ! Commas - semicolons - question marks are for girlie boys !
Only the video evidence proved that "significant portions of the cores of both buildings (roughly 60 stories of WTC 1 and 40 stories of WTC 2) are known to have stood 15 to 25 seconds after collapse initiation before they, too, began to collapse." The cores fell after the floors around them had already fallen. http://www.nist.gov/public_affairs/factsheet/wtc_faqs_082006.cfm Answers to Frequently Asked Questions (August 30, 2006) (8/6/2006, ARCHIVE, incorporated into 9/19/2011 update) [excerpt] 6. How could the WTC towers collapse in only 11 seconds (WTC 1) and 9 seconds (WTC 2)—speeds that approximate that of a ball dropped from similar height in a vacuum (with no air resistance)? NIST estimated the elapsed times for the first exterior panels to strike the ground after the collapse initiated in each of the towers to be approximately 11 seconds for WTC 1 and approximately 9 seconds for WTC 2. These elapsed times were based on: (1) precise timing of the initiation of collapse from video evidence, and (2) ground motion (seismic) signals recorded at Palisades, N.Y., that also were precisely time-calibrated for wave transmission times from lower Manhattan (see NCSTAR 1-5A). As documented in Section 6.14.4 of NIST NCSTAR 1, these collapse times show that: “… the structure below the level of collapse initiation offered minimal resistance to the falling building mass at and above the impact zone. The potential energy released by the downward movement of the large building mass far exceeded the capacity of the intact structure below to absorb that energy through energy of deformation. Since the stories below the level of collapse initiation provided little resistance to the tremendous energy released by the falling building mass, the building section above came down essentially in free fall, as seen in videos. As the stories below sequentially failed, the falling mass increased, further increasing the demand on the floors below, which were unable to arrest the moving mass.” In other words, the momentum (which equals mass times velocity) of the 12 to 28 stories (WTC 1 and WTC 2, respectively) falling on the supporting structure below (which was designed to support only the static weight of the floors above and not any dynamic effects due to the downward momentum) so greatly exceeded the strength capacity of the structure below that it (the structure below) was unable to stop or even to slow the falling mass. The downward momentum felt by each successive lower floor was even larger due to the increasing mass. From video evidence, significant portions of the cores of both buildings (roughly 60 stories of WTC 1 and 40 stories of WTC 2) are known to have stood 15 to 25 seconds after collapse initiation before they, too, began to collapse. Neither the duration of the seismic records nor video evidence (due to obstruction of view caused by debris clouds) are reliable indicators of the total time it took for each building to collapse completely.
Bigger, stronger steel provides greater resistance, not no resistance. It provides much more resistance than air. If the floors provided no resistance to the downforce, what created the horizontal force that ejected steel beams that were found in the sides of buildings hundreds of yards away?
The entire building hung on those... and they were destroyed by the airplane. It was a novel design that wasn't made to withstand attack from massive airliners.
Try some physics on a pool table ! If you ... don't use exclamation points --- you should't be typeing ! Commas - semicolons - question marks are for girlie boys !
That is just what it seems like to me. I'm not an expert. I could be wrong. Who knows. Regardless of the root cause of the collapse, There most certainly were a multitude of forces playing out during the collapse event itself. It's one of those things where predicting them correctly beforehand would have been an act of genius. For example some steel beams were projected laterally away from the building during the collapse which has been cited as evidence of foul play, but I think the amount of potential energy being released during the collapse to be enormous, and sufficient to launch such beams that way. We're used to seeing towers of wooden blocks and such fall to the side when playing party games of that sort, but I wouldn't expect that to be representative of something basically hollow as any skyscraper is. The mass is most certainly not to scale.
More bucking follocks. That was filmed in the 1980's The B-25 Empire State Building crash was a 1945 aircraft accident in which a B-25 Mitchell bomber, piloted in thick fog over New York City, crashed into the Empire State Building. The accident did not compromise the building's structural integrity, but it did cause fourteen deaths (three crewmen and eleven people in the building) and damage estimated at $1,000,000 ($13,000,000 in 2014 dollars) https://en.wikipedia.org/wiki/B-25_Empire_State_Building_crash Anyone remember the "Cold War"? No one imagined that an airplane could attack NY or DC. Right. There were probably no anti aircraft batteries around the Pentagon. Because no one could have imagined an airplane attacking the pentagon. Oh my sides. I've hurt myself laughing. Really. There's a weird pain in my tummy. Help me.
Fucking Truther crackpots and contrarian nutjobs. This is exactly why sane people refuse to "discuss" 9/11 with you assholes.
In the video I posted at 27. There is a huge rock hurled at some onlookers. Not a steel beam but the same thing could happen.
If that were a real pic of the NY Empire State bld King Kong would be on it. Shoo Truther.
I can't believe people are still arguing this. Since it is clearly evident that the collapse of the towers started at the point of plane impact in both towers, you have to believe one of two things if you believe they were brought down by a demolition: 1) That teams planted explosives at the exact places the planes would impact without anyone noticing, and the pilots were knowledgeable of and could hit these exact points. Also, you believe for some reason it took many minutes after the planes hit before the explosives detonated. or 2) That teams of explosives experts (that no one noticed) were in place at the points of impact and survived the impact. They then planted and detonated explosives after the impact on a suicide mission. So which one of these scenarios do you believe? And why the need for the planes anyway if the buildings could just brought down with explosives? You troofers have some convoluted thinking processes: WTC 7 was not hit by an airplane, so it must have been brought down by a demolition. So then WTCs 1 and 2 actually were brought down by the airplanes? No, they must have been brought down by explosives, too The blacksmith is just showing how ridiculous it is to think that the steel must have melted to bring down the buildings. Obama has played at being a president while enjoying the perks … golf, insanely expensive vacations at tax-payer expense. He has ignored the responsibilities of the job; no plans, no budgets, no alternatives … just finger pointing; making him a complete failure as a president
Aw, TooBusy is TooPissedOff! You are breaking my heart. TooFunny! I'm not interested in "discussing" anything with the likes of you, simpleton. Has your government ever lied to you? Do you care?
Couple questions: Why do you think that President Bush didn't want an investigation into the biggest crime against the US in history? Does that make sense? And when the families of the victims finally pressured the government into an investigation into the biggest crime against the US, Bush and Cheney insisted on testifying without being under oath and together. Does this not make you wonder why? Has your government ever lied to you? Do you care what is in the 28 pages that were censored from the official report? What do you think is in those pages? Your little 911 thread didn't go as you imagined, did it. Now bend over for the New World Order “The affirmative task we have now is to actually create a new world order”- Joe Biden, 2013 "That's not the way the world really works anymore. We're an empire now, and when we act, we create our own reality. And while you're studying that reality—judiciously, as you will—we'll act again, creating other new realities, which you can study too, and that's how things will sort out. We're history's actors…and you, all of you, will be left to just study what we do."- Karl Rove, 2004
Now bend over for the New World Order I have as little regard for the Bushs, Bidens, Roves et al as any man on this continent. Having said that, the extent to which there has been an attempt to disregard the fundamental laws of physics/engineering and other issues to construct a conspiracy among various politicians approaches an insanity which is detrimental to what the mission should be. There are plenty real elements to indict the corrupt establishment for without concocting foolish theories and conspiracies.
Dumbass fanatics. One big plus for Goldie's forum was she didn't let the Truther crackpots run wild. You notice that there are relatively few Truthers any more. Even the majority of them finally figured out that people hate them and hate all their bizarre rants about 9/11 conspiracy. So now the Truthers are just deadenders, the really toxic nobodies that will keep ranting about 9/11 and JFK and every other crackpot theory until they finally die off. As you would expect, the Truther stuff attracted a lot of very marginal personalities. As they evangelized -- primarily each other, preaching to the faithful, each with their own crackpot variations to their crackpot theories -- they became isolated from their previous friends and family (assuming they had any). As their isolation at work and with family and friends grew as a result of their crackpottery, they believed they were martyrs suffering for Truth with a capital 'T'. They're an annoying but very sad group.

Well, I was just speaking to the specific manner in which the towers fell. I am trying to address how the towers fell, and seeing that, what caused it.

An old girlfriend had this terribly annoying obnoxious little toy poodle. He was an anklebiter and would bark (well more like a grunt combined with a screech) as he tried to nip at the ankles of anyone that came over. This tiny, obnoxious, angry, foul smelling, hate filled toy poodle would sh*t all over whatever room he was in at the time. Over and over and over again. It was repulsive. You are that little obnoxious anklebiting toy poodle.
Typical- you can't seem to think outside the box. I want a new investigation, where Bush has to testify under oath.

Though we think of metals as inherently good conductors of heat, steel rates rather poorly there. Aluminum conducts heat quite rapidly by comparison. It's why steel pots & pans generally don't need much in the way of thermally insulated handles. The pot gets hot, yet the steel handle welded or riveted to it remains only warm to the touch.

His only peeve was that people had/have the impression that steel maintains the same structural strength at room temp as at 1800 degrees, below the melting point of steel.
E.3.6 Fire Exposure and Temperatures Reached by the Steel The pre-collapse photographic analysis showed that 16 recovered exterior panels were exposed to fire prior to collapse of WTC 1. None of the nine recovered panels from within the fire floors of WTC 2 were observed to have been directly exposed to pre-collapse fires. NIST developed a method to characterize maximum temperatures experienced by steel members using observations of paint cracking due to thermal expansion. The method can only probe the temperature reached and it cannot distinguish between pre-and post-collapse exposure. More than 170 areas were examined on the recovered perimeter column panels; however, these columns represented only 3 percent of the perimeter columns on the floors involved in fire and cannot be considered representative of other columns on these floors. Only three locations had evidence that the steel reached temperatures above 250°C. These areas were:
