It has been established through a study of the photographic and video evidence that there were a number of instances of white-hot areas that produced glowing liquid flows from window openings on the 80th to 82nd floor of WTC 2 that persisted for quite a number of seconds. According to the NIST FAQ these events came within the last 7 minutes before WTC 2 began its collapse. White-hot temperatures cannot be produced by ordinary fires. These observations have therefore been conclusively shown to be incendiary events. This fact is inconsistent with any theory of collapse except controlled demolition. Yet the official story remains that the buildings were brought down by fires and damage to the structural members of the buildings resulting from the impact of the planes. The WTC 7 wasn’t even hit by a plane, yet it is claimed that it was brought down by fires.
All three buildings, WTC 1, WTC 2 and WTC 7 were subjects of many video documents that remain today as some of the very best evidence for controlled demolition that we have. It is clear from the videos that explosives were used. The evidence for incendiary cutting of steel consists of the video evidence, the forensic evidence in the dust and rubble and the testimony of eyewitness early responders and survivors who saw glowing molten metal flowing out of window openings.
This paper deals with the incendiary events and the forensic evidence that remains to prove that the official story is wrong. Specifically, this paper discusses the chemistry of iron-aluminum-rich microspheres that are found in the dust from the rubble, the chemical content of these microspheres and the physical chemistry of the iron-sulfur-oxygen system since sulfur is one of the omnipresent elements in the iron-aluminum-rich microspheres and was also found in a metallurgical study of structural iron from WTC 7.
