Steel will melt at 2,750 ˚F.  In the history of high rise steel buildings world wide which experienced a fire, none collapsed.  The point in the building where the fire occurred was often gutted, but the building itself did not collapse.


            On August 28, 2006, Paul Craig Roberts, who served as Assistant Secretary of Treasury in the Reagan Administration, wrote an article in the American Free Press entitled, “How Gullible are our Fellow Americans?”  This article in part stated:


            Scientists and engineers, such as Clemson University Professor of Engineering Dr. Judy Woods and BYU Professor of Physics Dr. Steven Jones, have raised compelling questions about the official account of the collapse of the three WTC buildings.  The basic problem for the government’s account is that the buildings are known to have fallen at free-fall speed, a fact that is inconsistent with the government’s “pancaking” theory in which debris from above collapsed the floors below.  If the building actually “pancaked,” then each floor below would have offered resistance to the floors above, and the elapsed time would have been much longer.


            These experts have also calculated that the buildings did not have sufficient gravitational energy to accommodate the government’s theory of the collapse.  It is certainly a known and non-controversial fact among physicists and engineers that the only way buildings can collapse at free fall speed into their own footprints is by engineered demolition.  Explosives are used to remove the support of floors below the debris from above arrives.  Otherwise, resistance is encountered and time required for fall increases.


            Engineered demolition also explains the symmetrical collapse of the buildings into their own footprints.  As it is otherwise improbable for every point in floors below to weaken uniformly, “pancaking” would result in asymmetrical collapse as some elements of the floor would give sooner than others.


            Dr. Jones of BYU received a piece of rubble from the WTC.  He analyzed the debris and found there were large traces of sulfur and thermite.  Thermite is a chemical compound found in many explosives including C4.  It leaves a distinct smell and identifiable residue upon explosion.  Thermite has the capacity to heat steel to the melting temperature required for steel of 2,750 ˚F.  The placement of thermite in the World Trade Center buildings would explain how the explosions and heat would produce temperatures high enough to melt steel and cause the collapse of the twin towers in 8 and 10 seconds.
