The Destruction Of The World Trade Center: Why The Official Account Of 911 Cannot Be True

Global Research Editor’s Note

As September approaches, we are reminded that the anniversary of the tragic events of 9/11 will soon be upon us once again. 11 years laters, are we any closer to the truth about what really happened on that fateful day?

For the next month until September 11, 2012, we will be posting on a daily basis important articles from our early archives pertaining to the tragic events of 9/11.

“The official theory about the Twin Towers is that they collapsed because of the combined effect of the impact of the airplanes and the resulting fire.

The following text by Professor David Ray Griffin originally published on Global Research in January 2006 forecefully refutes the official narrative. 

The Destruction of the World Trade Center: Why the Official Account Cannot Be True

But this way of presenting the evidence has one great limitation, especially when used in lectures and essays: It means that the treatment of every particular issue must be quite brief, hence superficial. People can thereby be led to suspect that a more thorough treatment of any particular issue might show the official story to be plausible after all.

In the present essay, I focus on one question: why the Twin Towers and building 7 of the World Trade Center collapsed. One advantage of this focus, besides the fact that it allows us to go into considerable detail, is that the destruction of the World Trade Center provides one of the best windows into the truth about 9/11. Another advantage of this focus is that it will allow us to look at revelations contained in the 9/11 oral histories, which were recorded by the New York Fire Department shortly after 9/11 but released to the public only in August of 2005.

I will begin with the question of why the Twin Towers collapsed, then raise the same question about building 7.

1. The Collapse of the Twin Towers

Shortly after 9/11, President Bush advised people not to tolerate “outrageous conspiracy theories about the attacks of 11 September” (Bush, 2001).[2] Philip Zelikow, who directed the work of the 9/11 Commission, has likewise warned against “outrageous conspiracy theories” (Hansen, 2005). What do these men mean by this expression? They cannot mean that we should reject all conspiracy theories about 9/11, because the government’s own account is a conspiracy theory, with the conspirators all being members of al-Qaeda. They mean only that we should reject outrageous theories.

But what distinguishes an outrageous theory from a non-outrageous one? This is one of the central questions in the philosophy of science. When confronted by rival theories—let’s say Neo-Darwinian Evolution and Intelligent Design—scientists and philosophers of science ask which theory is better and why. The mark of a good theory is that it can explain, in a coherent way, all or at least most of the relevant facts and is not contradicted by any of them. A bad theory is one that is contradicted by some of the relevant facts. An outrageous theory would be one that is contradicted by virtually all the relevant facts.

With this definition in mind, let us look at the official theory about the Twin Towers, which says that they collapsed because of the combined effect of the impact of the airplanes and the resulting fires. The report put out by FEMA said: “The structural damage sustained by each tower from the impact, combined with the ensuing fires, resulted in the total collapse of each building” (FEMA, 2002).[3] This theory clearly belongs in the category of outrageous theories, because is it is contradicted by virtually all the relevant facts. Although this statement may seem extreme, I will explain why it is not.

No Prior Collapse Induced by Fire

The official theory is rendered implausible by two major problems. The first is the simple fact that fire has never—prior to or after 9/11—caused steel-frame high-rise buildings to collapse. Defenders of the official story seldom if ever mention this simple fact. Indeed, the supposedly definitive report put out by NIST—the National Institute for Standards and Technology (2005)—even implies that fire-induced collapses of large steel-frame buildings are normal events (Hoffman, 2005).[4] Far from being normal, however, such collapses have never occurred, except for the alleged cases of 9/11.

Defenders of the official theory, of course, say that the collapses were caused not simply by the fire but the fire combined with the damage caused by the airliners. The towers, however, were designed to withstand the impact of airliners about the same size as Boeing 767s.[5] Hyman Brown, the construction manager of the Twin Towers, said: “They were over-designed to withstand almost anything, including hurricanes, . . . bombings and an airplane hitting [them]” (Bollyn, 2001). And even Thomas Eagar, an MIT professor of materials engineering who supports the official theory, says that the impact of the airplanes would not have been significant, because “the number of columns lost on the initial impact was not large and the loads were shifted to remaining columns in this highly redundant structure” (Eagar and Musso, 2001, pp. 8-11). Likewise, the NIST Report, in discussing how the impact of the planes contributed to the collapse, focuses primarily on the claim that the planes dislodged a lot of the fire-proofing from the steel.[6]

The official theory of the collapse, therefore, is essentially a fire theory, so it cannot be emphasized too much that fire has never caused large steel-frame buildings to collapse—never, whether before 9/11, or after 9/11, or anywhere in the world on 9/11 except allegedly New York City—never.

One might say, of course, that there is a first time for everything, and that a truly extraordinary fire might induce a collapse. Let us examine this idea. What would count as an extraordinary fire? Given the properties of steel, a fire would need to be very hot, very big, and very long-lasting. But the fires in the towers did not have even one of these characteristics, let alone all three.

There have been claims, to be sure, that the fires were very hot. Some television specials claimed that the towers collapsed because the fire was hot enough to melt the steel. For example, an early BBC News special quoted Hyman Brown as saying: “steel melts, and 24,000 gallons of aviation fluid melted the steel.” Another man, presented as a structural engineer, said: “It was the fire that killed the buildings. There’s nothing on earth that could survive those temperatures with that amount of fuel burning. . . . The columns would have melted” (Barter, 2001).[7]

These claims, however, are absurd. Steel does not even begin to melt until it reaches almost 2800° Fahrenheit.[8] And yet open fires fueled by hydrocarbons, such as kerosene—which is what jet fuel is—can at most rise to 1700°F, which is almost 1100 degrees below the melting point of steel.[9] We can, accordingly, dismiss the claim that the towers collapsed because their steel columns melted.[10]

Most defenders of the official theory, in fact, do not make this absurd claim. They say merely that the fire heated the steel up to the point where it lost so much of its strength that it buckled.[11] For example, Thomas Eagar, saying that steel loses 80 percent of its strength when it is heated to 1,300°F, argues that this is what happened. But for even this claim to plausible, the fires would have still had to be pretty hot.

But they were not. Claims have been made, as we have seen, about the jet fuel. But much of it burned up very quickly in the enormous fireballs produced when the planes hit the buildings, and rest was gone within 10 minutes,[12] after which the flames died down. Photographs of the towers 15 minutes after they were struck show few flames and lots of black smoke, a sign that the fires were oxygen-starved. Thomas Eagar, recognizing this fact, says that the fires were “probably only about 1,200 or 1,300°F” (Eagar, 2002).

There are reasons to believe, moreover, that the fires were not even that hot. As photographs show, the fires did not break windows or even spread much beyond their points of origin (Hufschmid, 2002, p. 40). This photographic evidence is supported by scientific studies carried out by NIST, which found that of the 16 perimeter columns examined, “only three columns had evidence that the steel reached temperatures above 250°C [482°F],” and no evidence that any of the core columns had reached even those temperatures (2005, p. 88).

NIST (2005) says that it “did not generalize these results, since the examined columns represented only 3 percent of the perimeter columns and 1 percent of the core columns from the fire floors”. That only such a tiny percent of the columns was available was due, of course, to the fact that government officials had most of the steel immediately sold and shipped off. In any case, NIST’s findings on the basis of this tiny percent of the columns are not irrelevant: They mean that any speculations that some of the core columns reached much higher temperatures would be just that—pure speculation not backed up by any empirical evidence.

Moreover, even if the fire had reached 1,300°F, as Eagar supposes, that does not mean that any of the steel would have reached that temperature. Steel is an excellent conductor of heat. Put a fire to one part of a long bar of steel and the heat will quickly diffuse to the other parts and to any other pieces of steel to which that bar is connected.[13]

For fires to have heated up some of the steel columns to anywhere close to their own temperature, they would have needed to be very big, relative to the size of the buildings and the amount of steel in them. The towers, of course, were huge and had an enormous amount of steel. A small, localized fire of 1,300°F would never have heated any of the steel columns even close to that temperature, because the heat would have been quickly dispersed throughout the building.

Some defenders of the official story have claimed that the fires were indeed very big, turning the buildings into “towering infernos.” But all the evidence counts against this claim, especially with regard to the south tower, which collapsed first. This tower was struck between floors 78 and 84, so that region is where the fire would have been the biggest. And yet Brian Clark, a survivor, said that when he got down to the 80th floor: “You could see through the wall and the cracks and see flames . . . just licking up, not a roaring inferno, just quiet flames licking up and smoke sort of eking through the wall.”[14] Likewise, one of the fire chiefs who had reached the 78th floor found only “two isolated pockets of fire.”[15]

The north tower, to be sure, did have fires that were big enough and hot enough to cause many people to jump to their deaths. But as anyone with a fireplace grate or a pot-belly stove knows, fire that will not harm steel or even iron will burn human flesh. Also in many cases it may have been more the smoke than the heat that led people to jump.

In any case, the fires, to weaken the steel columns, would have needed to be not only very big and very hot but also very long-lasting.[16] The public was told that the towers had such fires, with CNN saying that “very intense” fires “burned for a long time.”[17] But they did not. The north tower collapsed an hour and 42 minutes after it was struck; the south tower collapsed after only 56 minutes.

To see how ludicrous is the claim that the short-lived fires in the towers could have induced structural collapse, we can compare them with some other fires. In 1988, a fire in the First Interstate Bank Building in Los Angeles raged for 3.5 hours and gutted 5 of this building’s 62 floors, but there was no significant structural damage (FEMA, 1988). In 1991, a huge fire in Philadelphia’s One Meridian Plaza lasted for 18 hours and gutted 8 of the building’s 38 floors, but, said the FEMA report, although “[b]eams and girders sagged and twisted . . . under severe fire exposures. . . , the columns continued to support their loads without obvious damage” (FEMA, 1991). In Caracas in 2004, a fire in a 50-story building raged for 17 hours, completely gutting the building’s top 20 floors, and yet it did not collapse (Nieto, 2004). And yet we are supposed to believe that a 56-minute fire caused the south tower to collapse.

Unlike the fires in the towers, moreover, the fires in Los Angeles, Philadelphia, and Caracas were hot enough to break windows.

Another important comparison is afforded by a series of experiments run in Great Britain in the mid-1990s to see what kind of damage could be done to steel-frame buildings by subjecting them to extremely hot, all-consuming fires that lasted for many hours. FEMA, having reviewed those experiments, said: “Despite the temperature of the steel beams reaching 800-900°C (1,500-1,700°F) in three of the tests. . . , no collapse was observed in any of the six experiments” (1988, Appendix A).

These comparisons bring out the absurdity of NIST’s claim that the towers collapsed because the planes knocked the fireproofing off the steel columns. Fireproofing provides protection for only a few hours, so the steel in the buildings in Philadelphia and Caracas would have been directly exposed to raging fires for 14 or more hours, and yet this steel did not buckle. NIST claims, nevertheless, that the steel in the south tower buckled because it was directly exposed to flames for 56 minutes.[18]

A claim made by some defenders of the official theory is to speculate that there was something about the Twin Towers that made them uniquely vulnerable to fire. But these speculations are not backed up by any evidence. And, as Norman Glover, has pointed out: “[A]lmost all large buildings will be the location for a major fire in their useful life. No major high-rise building has ever collapsed from fire. The WTC was the location for such a fire in 1975; however, the building survived with minor damage and was repaired and returned to service” (Glover, 2002).
