Magnetic forces to blame for 9/11 tower collapse By Steve Connor Wednesday, 10 September 2008 Scientists can finally explain why the Twin Towers collapsed on September 11, despite the temperature of the fires being well below the 1,500C melting point of the steel girders holding up the buildings. The discovery that unusual magnetic forces within the girders made them weak at temperatures of about 500C explains away the conspiracy theories that have spread like wildfire since the disaster. Sergei Dudarev, of the UK Atomic Energy Agency, found that steel loses its strength above 500C because its molecules undergo a physical transition from one state to another due to magnetic fluctuations. "The steel didn't melt, it just became soft. It is an unusual state and the temperatures in the Twin Towers were high enough to cause it because the thermal insulation was knocked off the girders through the impact with the aircraft," he said. "Understanding how materials behave means we can find the right 'medicine' to make steel stronger at high temperatures... and if our work can be used for other applications, such as safeguarding tall buildings against disasters, so much the better," he said.

It's not an unusual state. Any blacksmith can tell you that when heated at temperatures well below the level produced in the WTC fires, steel and iron weaken and become malleable. Some conspiracy nuts think that the only way steel can weaken is if it's heated to complete liquification; they were only demonstrating their own ignorance. And, by the way, some nut started the story of a pool of molten steel at Ground Zero, still liquid days after the collapse. Simply impossible. Even a nuclear explosion wouldn't have that effect. Nobody did a metallic analysis that showed this was steel or any other normal metal. What was seen was a greyish puddle of a variety of fluids, including water, paint, melted plastic, various industrial liquids, that had mixed together from the fire, collapse and fire fighting efforts at the WTC.

With respect, Shoonra, go fuck yourself. Not only did we see Building 7 burn to a crisp on that ill-fated day, but a number of very significant highrise conflagrations have also transpired since then to demonstrate quite clearly that modern steel construction does not suffer catastrophic disintegration from fire alone. And be gone, you foul spirit. Hence to your master.

Does your frying pan turn to silly putty when you fry an egg? And, by the way, some nut started the story of a pool of molten steel at Ground Zero, still liquid days after the collapse. Simply impossible. BTW, what do you think these images indicate? Click on image below for video;
Tell that to the NYC News Crew that filmed the firefighters pulling red hot steel out of the rubble 6 WEEKS after the towers collapsed. Let me repeat that in the event you are reading challenged a NYC News Crew filmed the firefighters pulling red hot steel out of the rubble 6 WEEKS after the towers collapsed. As well the molten pools of red hot metal were reported by knowledgable individuals. Here is one of the videos: Molten Steel 8 WEEKS after Towers Collapse. Archives on What Really Happened - including video documentation
Pure speculation. Many, many witnesses reported molten iron or metal at the WTC. The $20 million NIST study presents not one piece of core steel showing heating above 480 degrees F--no physical evidence to support the claim that high temperature fires weakened the steel. Other factors brought down WTC 1,2 and 7. Office fires were not the cause.
So how did it(the steel) explode and what produced the pyroclastic flow ?
According to the Journal of Australian Fire Investigators, kerosene ignites at around 444°F. The temperature that the fire will eventually reach depends on both the combustion rate (based on O2) and the rate at which heat can be disbursed in the given scenario. Again, any firefighter can explain from experience and training that the black, sooty smoke (like that found on 9/11 at the WTC towers) were O2 deprived. Again, please contact professionals to verify this if you wish. In an oxygen deprived environment, higher temperatures cannot be reached. You can test this yourself by comparing a match in the open vs. a match in a bottle with a very small hole. T.C. Forensic: Article 10 - PHYSICAL CONSTANTS FOR INVESTIGATORS
TAKE A LOOK AT THESE PICTURES OF THE BUILDINGS ON FIRE!
http://www.whatreallyhappened.com/911_reichstag.html The 9/11 Reichstag Fire Reichstag Fire Reichstag fire, burning of the Reichstag (parliament) building in Berlin, on the night of Feb. 27, 1933, a key event in the establishment of the Nazi dictatorship and widely believed to have been contrived by the newly formed Nazi government itself to turn public opinion against its opponents and to assume emergency powers ... his propaganda minister, Joseph Goebbels, is supposed to have devised the scheme. ... On Feb. 28, 1933, the day after the fire, Hitler's dictatorship began with the enactment of a decree "for the Protection of the People and the State," which dispensed with all constitutional protection of political, personal, and property rights. Encyclopaedia Britannica Excerpt from History Channel documentary detailing evidence of Hitler's supporters burning down the Reichstag in 1933 5.6 MB RealMedia video The Reichstag fire was a disaster for Communists because they received the blame for starting it, but it was a dream come true for Hitler and his cohorts as it allowed them to turn Germany into a dictatorship. Did the Bush administration try the same trick on September 11, 2001? The victims of the 9/11 attacks have been disaster for Muslims because 19 Arabs were named as hijackers of the planes, but they've been a dream come true for the PNAC 'think-tank' whose 2000 Statement of Principles stated a "catastrophic and catalyzing event, like a new Pearl Harbor" would advance their policies, i.e. justify wars and "regime changes". "This is about control over Middle East oil. [The Statement of Principles] indicates that America is aiming for global leadership, both military and economically..." - Michael Meacher, UK MP WMV video download (831kB) The fact that Pearl Harbor was engineered by the US government to bring America into WWII would have been known by PNAC signatories... 10 [PNAC members] are now in the Bush administration. As well as Rumsfeld and Wolfowitz, they include Deputy Secretary of State Richard Armitage; John Bolton, who is undersecretary of state for disarmament; and Zalmay Khalilzad, the White House liaison to the Iraqi opposition. Other signatories include William Kristol, editor of the conservative Weekly Standard magazine, and Richard Perle, chairman of the advisory Defense Science Board. [ABC News 3/10/2003] ...so their statement actually referred to policy advancement through a governmentally orchestrated "catastrophic and catalyzing event" - Operation Northwoods is an example of this thinking. The "new Pearl Harbor" occurred on 9/11... Like his father, Bush tries to keep a daily diary of his thoughts and observations. That night, he dictated: "The Pearl Harbor of the 21st century took place today." [Washington Post] ...and now wars and "regime changes" are justified by the events of that day: U.S. President George W Bush ... defended the war in Iraq, telling Americans the United States was forced into war because of the Sept 11 terror strikes. [Japan Today 17/06/05] "The Pearl Harbor of the 21st century" effectively thrust PNAC's radical ideas to the fore... The terror attacks of Sept. 11, 2001, and concerns that another similar attack might follow, gave Defense Secretary Donald H. Rumsfeld "a tremendous sense of urgency" in pushing his transformation effort ... . Rumsfeld said ... the Sept. 11 attacks underscored the importance of the transformation program he announced Sept. 10, 2001. [American Forces Press Service] ...so were the events of 9/11 governmentally orchestrated? "In politics, nothing happens by accident. If it happens, you can bet it was planned that way." - Franklin D. Roosevelt There were many exercises prior to 9/11 which related specifically to the events of that day: NORAD conducted exercises with fighter jets simulating hijacked planes flown into the World Trade Center in the two years before the attacks. Pentagon planners also envisioned the attack on the Pentagon five months before it happened. WMV video download (936kB) On June 2, 2001 PNAC signatory Paul Wolfowitz predicted a military surprise: "Military history is full of surprises, even if few are as dramatic or memorable as Pearl Harbor. Surprises happen so often, that is is surprising that we're still surprised by it. ... Be prepared to be surprised. Have courage." [defenselink.mil] From July 26, 2001 John Ashcroft stopped traveling on commercial airlines: In response to inquiries from CBS News over why Ashcroft was traveling exclusively by leased jet aircraft instead of commercial airlines, the Justice Department cited what it called a "threat assessment" by the FBI, and said Ashcroft has been advised to travel only by private jet for the remainder of his term. [CBS News] World Trade Center staff received evacuation drills prior to 9/11: Ben Fountain, 42, a financial analyst with Fireman's Fund, was coming out of the Chambers Street Station, headed for his office on the 47th floor of the south tower. "How could they let this happen? They knew this building was a target. Over the past few weeks we'd been evacuated a number of times, which is unusual. I think they had an inkling something was going on." [People] On September 10 top Pentagon officials were compelled to cancel travel plans: On Sept. 10, NEWSWEEK has learned, a group of top Pentagon officials suddenly canceled travel plans for the next morning, apparently because of security concerns. [MSNBC 9/24/2001] Also on September 10 Willie Brown, the former Mayor of San Francisco, was warned about air travel: Brown received a warning about 10 PM on the evening of September 10 to be cautious about air travel. He was scheduled to fly to into New York City. Brown refuses to say exactly who gave him the prescient warning, citing only "my security people at the airport." [SFGate 9/12/2001] President Bush's cousin had a fortunate change of venue for a September 11 business conference: President Bush's cousin should have been in the World Trade Centre when it was attacked. Jim Pierce, managing director of AON Corporations, had arranged a business conference on the 105th floor of the South Tower where its New York offices were based. But his group was too large so they decided to move across the street to the Millennium Hotel. [Annova] An imminent attack was forecast... "The Director of the CIA warned that there could be an attack—an imminent attack—on the United States of this nature. So this is not entirely unexpected." [Memory Hole] ...maybe that's why FEMA was in New York on September 10. Last, but not least, the timing of the 9/11 attacks was a "Godsend" for the Bush Administration. I guess the above may be seen as coincidences, but why did planes flying into buildings prompt White House staff to start taking Cipro? In October [2001], press reports revealed that White House staff had been on a regimen of the powerful antibiotic Cipro since the Sept. 11 terrorist attacks. Judicial Watch wants to know why White House workers, including President Bush, began taking the drug nearly a month before anthrax was detected on Capitol Hill. [WorldNetDaily]
Any backyard griller can tell you that their grills never collapse to the ground at free fall speed despite grilling all day. Government stooges like you have a special place reserved for you in hell.
Yawn. Inevitably we get an endless redux of the same shabby shopworn tactics to buttress the "Official Conspiracy Theory®" over and over and over again. Does anyone who has looked at the situation seriously suggest that liquefaction was neccessary for the towers to collapse? NO. They do not and you can produce no reference or quote, from a credible researcher, to support your poor lame Straw Man. On the flip side neither can you produce any credible evidence or authoritative, based on actual engineering science, explanation as to how the towers collapse symmetrically, uniformly, within 1 hour, and how the initial collapse was initiated simultaneously in 360 degrees by fires localized in limited areas; which the one fire crew to reach the scene radioed back required only 3 Hose Crews to "knock down the flames". It is amusing to watch the "Official Conspiracy Theory®" morph over time and yet remain so much the same: "19Arabswhohateuscuzwe'refree" directed by a madman in the mountains of Tora Bora, with his "Magic Cellphone©", highjacked 4 airliners, in the most controlled airspace on the planet with box cutters and Pepper Spray, while striking such lightning speed and professional coordination as to prevent all 4 from broadcasting the 4 digit highjack code - following a final night of boozing and whoring while conspicuously leaving a Koran in a Bar (disregard that as these were fanatically devout Muslims to who such activities are prohibited by their fanatical religious laws), cast a spell to put NORAD to sleep, and then proceeded to leisurely crash 3 of those planes into massive structures built of interlocking reinforced steel girders (as much as 4 feet thick in places) causing them to tumble as though made of toothpicks neatly into their own footprints at nearly freefall speed. It is almost breathtaking each time I see someone travel again down and around the FruitLoop attempting to float the latest preposterous planted explanation to justify the "Official Conspiracy Theory®". We have gone from jet fuel to office fires to not even mentioning a source for the heat but just asserting that it somehow magically existed. Of course even NIST and FEMA have been forced to admit that the Jet Fuel, initially used to justify the collapse, all burned up in the first ten minutes, and that Class Alpha Office Fires don't get hot enough to weaken steel. And yet each and every time we get a defender of the "Official Conspiracy Theory®" they always come back to some form of "incredible heat weakened the steel" cause by yet another in a succession of preposterous mechanisms for localized fires to create a uniform, symmetrical, simultaneous, collapse in 360 degrees, while not accounting for the resistance of the underlying structure to collapse. For a theory to be valid it must account for uniformly, predictably, and reproducibly, ALL of the observed phenomena. Yours, as usual with all shills/government apologists, does not. Of course there was one thing uniformly demolished - your argument. The "nuclear explosion" quip is another delightful introduction of our old friend the Strawman. Unfortunately for your specious argument there exist a number of videos showing the recovery of molten debris up to 8 weeks after the Towers collapse. It is just so unfortunate for your childish petulant denial that the recovery of molten material from the Ground Zero was been recorded on more than one video. As well as having multiple witnesses attesting to the fact. I do not have to provide an explanation to simply show that your argument is false so don't even try that one. You are welcome to try and explain away documented evidence - that should be most amusing.

Any blacksmith can tell you that when heated at temperatures well below the level produced in the WTC fires, steel and iron weaken and become malleable.

Strawman Argument
"Straw man" is one of the best-named fallacies, because it is memorable and vividly illustrates the nature of the fallacy. Imagine a fight in which one of the combatants sets up a man of straw, attacks it, then proclaims victory. All the while, the real opponent stands by untouched. And, by the way, some nut started the story of a pool of molten steel at Ground Zero, still liquid days after the collapse. Simply impossible. Even a nuclear explosion wouldn't have that effect.
Nuclear debris still producing radioactivity could, in a confined space such as a rubble pile, continue to generate sufficient heat, YEARS after the fact, to keep molten or near molten steel trapped near it in the rubble pile. Earth to Mikey/Shoonra - that is why Nuclear Piles require "cooling" water. They use it to, uh, prevent the pile from melting the containment vessel (as well as damp the reaction).
