Abstract: In the debate over the collapses of the Twin Towers on 9/11, the shaking of the earth that accompanied these collapses has played an important role. This shaking registered clearly on seismographs. Less clear, however, are its causes and the times it began. The National…
Abstract: In its Final Report on the Collapse of the World Trade Center Towers, the National Institute of Standards and Technology summarizes its three year study and outlines its explanation of the total collapse of WTC 1 and WTC 2. Readers of the report will find…
Abstract: We have discovered distinctive red/gray chips in all the samples we have studied of the dust produced by the destruction of the World Trade Center. Examination of four of these samples, collected from separate sites, is reported in this paper. These red/gray chips show…
“Regardless of how thermite materials were installed in the WTC, it is strange that NIST has been so blind to any such possibility. In fact, when reading NIST’s reports on the WTC, and its periodic responses to FAQs from the public, one might get the…
Introduction: There have been a number of authors who have drawn attention to the improbability of certain reported events that led up to the disaster that has become known as 9/11, in which three major buildings at the World Trade Centre collapsed with heavy loss of…
Abstract: Reports by FEMA and NIST lay out the official account of the destruction of the World Trade Center on 9/11/2001. In this Letter, we wish to set a foundation for productive discussion and understanding by focusing on those areas where we find common ground…
Abstract: Investigators monitoring air quality at the World Trade Center, after the September 11th attacks, found extremely high levels of volatile organic chemicals as well as unusual species that had never been seen before in structure fires. Data collected by the U.S. Environmental Protection Agency…
Abstract: On September 11, 2001 there were numerous advance warnings of World Trade Center 7’s collapse, and many people have argued that these warnings are evidence that the building was subjected to controlled demolition. But other researchers feel the warnings are compatible with the hypothesis of…
Abstract: In an effort to better understand the conditions that led to complete collapses of the World Trade Center Towers and WTC 7, we apply scanning electron-microscope (SEM) and energy dispersive x-ray spectroscopy (XEDS) methods to analyze the dust generated, with an emphasis on observed micro-spheres…
Introduction: Numerous arguments have been presented that the Twin Towers at the World Trade Centre could not have collapsed in the observed manner due to the cause asserted in the NIST report, namely damage from plane impact and fire. The bases of these arguments include the…
