What appears to be molten steel pours from a fracture in the wall of WTC south tower. Steel melts at 2500 F. The only other known sources of heat on that day were jet fuel, (which burns at 1500 F) and office fires (which burn at an even lower temperature, owing to oxygen starvation). The NYFD Fire Director was on the impacted floors and reported an orderly evacuation, i.e., no extraordinary heat. The most likely source of heat sufficient to melt steel support columns is thermite, an incendiary premixture of powdered iron oxide and granular aluminum.

Steel ejected outward
Outer support columns for the World Trade Center north tower are hurled outward 70 meters or more by the force of explosives going off sequentially inside the tower. Such force could not be produced by the compressed air of “pancaking.” (See the video to the right for a normal demolition job.) The purpose of the explosives may have been to ensure that the interior columns, far more massive than the outer ones, did not remain standing – as they certainly would have in a pancaking mechanism. The grey clouds appear to be largely concrete, pulverized into fine dust by the same explosives.

The crash site consists of a rather small impact crater surrounded by undisturbed lawn or mowed field. The crater is more consistent with the effect of a smaller aircraft in a vertical, power dive. Prior to 9/11 every serious commercial airliner terrestrial impact followed the same pattern, a gouge rather than a crater, a debris field consisting of aircraft parts, passenger seats and any other element of the aircraft separable by collision, and a blackened, generally burned area. All three aspects are missing from this and other images of the crash site, barring only minor elements.

Collapse of WTC 7
The World Trade Center Building 7 had a few small office fires burning on a few floors, with no possibility whatever of a fire-induced collapse. Indeed, the building’s leaseholder, Larry Silverstein, has admitted on videotape to having the building brought down by controlled demolition or “pulled.” Note that as the building collapses, the effect of compressed air trapped inside the structure is negligible. The explosives used in this case were probably the ones normally employed in “pulling” buildings, there being no massive interior support columns to retard the collapse. Obviously, the building was pre-wired for demolition well before 9/11.

Virtually all video images taken of the plane about to strike the south tower of the World Trade Center show a bright flash within the building wall just ahead of the incoming aircraft. This is not an electric discharge, as some have claimed. Not only is such a bright discharge unlikely, there is no discharge path between the aircraft and the building. Indeed, some videos, taken at an oblique angle, show an elliptical shape to the flash, a bright disk, as it were, seen from the side. It may reasonably be supposed that a charge of thermite planted at the planned impact site was ignited a few seconds before impact, reaching an incandescent temperature just before impact. The purpose of such a charge (along with other charges inside the building) would be to “soften” the target, allowing the entire aircraft to enter the building, ensuring that no part of it would fall to the street below.
