"BYU's Dr. David Ray Griffin: The Destruction of the World Trade Center: Why the Official Account Cannot Be True"

...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]
