Study: 'highly engineered explosive' found in WTC rubble
A team of scientists claim to have unearthed startling data from dust and debris gathered in the days and weeks after the World Trade Center towers collapsed on Sept. 11, 2001.
In a study published by the Open Chemical Physics Journal -- a peer-reviewed, scientific publication -- Steven E. Jones and Niels Harrit level an stark allegation: that within the dust and rubble of the World Trade Center towers lays evidence of "a highly engineered explosive," contrary to all federal studies of the collapses.
"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," reads the paper's abstract. "One sample was collected by a Manhattan resident about ten minutes after the collapse of the second WTC Tower, two the next day, and a fourth about a week later. The properties of these chips were analyzed using optical microscopy, scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy (XEDS), and differential scanning calorimetry (DSC)."
They claim their analysis has uncovered "active thermitic material": a combination of elemental aluminum and iron oxide in form of thermite known as "nanostructured super-thermite."
Thermite, used in steel welding, fireworks shows, hand grenades and demolition, can produce a chemical reaction known for extremely high temperatures focused in a very small area for a short period of time.
According to the Navy's Small Business Innovation Research, super-thermite "is restricted under the International Traffic in Arms Regulation (ITAR), which controls the export and import of defense-related material and services."
"This finding really goes beyond anything that has previously been shown," said Jones in a media advisory. "We had to use sophisticated tools to analyze the dust because this isn't just a typical explosive, RDX or CD4 or something -- this is a highly engineered material not readily available to just anyone."
"The cost and production rate of super-thermite composites has limited the use of these materials in DoD applications," claims the Navy's SBIR.
Dr. Steven E. Jones, a former physicist at Brigham Young University and a founding member of Scholars for 9/11 Truth & Justice, presented a paper in 2005 discussing alternatives to the government's theory that massive structural damage combined with burning jet fuel to weaken the towers' support infrastructure, causing a rapid "pancake" collapse.
In September 2006, under heavy criticism in the media and several colleagues, the university placed Jones on paid administrative leave and his paper was removed from the BYU database.
The National Institute of Standards and Technology, which investigated the WTC tower collapses, maintains there was no recovered evidence of explosive materials. An electronic FAQ to the government's theory is available online.
"We get a lot of calls from people who have heard these theories," NIST spokesman Michael Newman told Newsday. "But we conducted what was probably the most complex investigation of a building collapse in history."
"We based our conclusion on the talents of the world's best engineers and scientists, state of the art computer models and 236 pieces of steel recovered from the site," reads the NIST FAQ.
"The collapse of the WTC towers was not caused either by a conventional building fire or even solely by the concurrent multi-floor fires that day," NIST says. "Instead, NIST concluded that the WTC towers collapsed because: (1) the impact of the planes severed and damaged support columns, dislodged fireproofing insulation coating the steel floor trusses and steel columns, and widely dispersed jet fuel over multiple floors; and (2) the subsequent unusually large, jet-fuel ignited multi-floor fires weakened the now susceptible structural steel."
"No building in the United States has ever been subjected to the massive structural damage and concurrent multi-floor fires that the towers experienced on Sept. 11, 2001," the agency claims.
This latest report, Jones told Visibility 9/11, "explodes the official story that 'no evidence' exists for explosive/pyrotechnic materials in the WTC buildings. The red/gray chips are the 'loaded gun' of 9-11."
