Architects and Engineers for 911 Truth

Figure 1. The black smoke at the Twin Towers was indicative of the incomplete combustion usually associated with low-temperature fires. Office fires cannot melt steel, even given optimal conditions.

 

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 Official Fired-Based Hypothesis Cannot Account for the Stream of Liquid Metal Pouring Out of the South Tower

Figure 2. Yellow-white glowing molten metal is seen pouring from the South Tower just minutes before its collapse. Accompanying white smoke was sometimes visible. NIST did not investigate the phenomenon.
