A December 2001 paper, “Why Did the World Trade Center Collapse? Science, Engineering, and Speculation,” dismissed early reports about molten steel at the demolished World Trade Center. Dr. Thomas W. Eagar, a professor of materials engineering and engineering systems at the Massachusetts Institute of Technology, and his graduate research student, Christopher Musso, pointed out that the theoretical maximum temperature of a building fire (maximum 1000°C/1800°F) is not even close to the melting point of steel (approximately 1500°C/2750°F). And they noted that the observed black smoke emanating from the Twin Towers was consistent with a typical oxygen-starved building fire.
Eagar and Musso concluded that the actual temperature most likely remained below 650°C/1200°F. In so doing, they dispelled the myth that the jet fuel could have made the fires unusually hot, noting that it was “highly unlikely” that the temperature rose above 800°C/1470°F.
AE911Truth agrees that the jet-fuel-induced fires in the Twin Towers could not have melted steel.
But because more recent reports confirm the presence of molten steel and molten iron both during and after the 9/11 event, it must be determined what actually melted those two metals and in so doing demolished two of the world’s tallest steel-frame skyscrapers.

The National Institute of Standards and Technology (NIST) did document the flow of molten metal pouring out of the South Tower during the final seven minutes before its collapse, noting the accompanying “unusual bright flame” and “plume of white smoke.” However, NIST failed to investigate the phenomenon, dismissing it as molten aluminum from the crashed jet, which melts at only 660°C/1220°F.
NIST’s hypothesis may seem plausible at first. But Dr. Steven Jones demonstrates in his 2006 paper “Why Indeed Did the WTC Buildings Completely Collapse?” that the official government hypothesis is untested and implausible.
Dr. Jones’ paper reveals that the initial bright yellow-white glow of the expelled liquid was consistent with a glowing stream of molten iron from “a nearby thermite reaction zone,” and the expected white smoke (aluminum oxide off-gassing) supports that conclusion. NIST must rely on its claim of molten aluminum in order to validate its official fire-based explanation, because office fires cannot generate the extreme temperature required to melt steel or iron. The fundamental flaw of the aluminum hypothesis, though, is that the implied temperature of the white glow remains above 1200°C/2200°F, regardless of the metal involved. An independent researcher suggested that the molten substance could be lead from storage batteries, but this explanation fails — as do all hypotheses based on alternative metals — because the temperature required for the yellow-white glow of the metal is beyond the capability of the building fire.
