The polished but someWhat threadbare fantasy that the US Government has promoted to explain the events on 9/11 is slowly eroding - the evidence is stacking up and the Expertise and experience of criticial authors is further establishing what really happened.
In an article published this week in the journal Environmentalist, chemical engineer Kevin Ryan collects evidence from EPA documents that suggest there was both Thermate and high-explosives in the debris from the WTC collapse. Ryan was formerly employed by Environmental Health Labs, a division of Underwriters Labs. He was fired for raising these and other questions.

Environmental anomalies at the World Trade Center: evidence for energetic materials
Kevin R. Ryan Æ James R. Gourley Æ Steven E. Jones
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 indicate striking spikes in levels of benzene, styrene, and several other products of combustion.
These spikes occurred on specific dates in October and November 2001, and February 2002. Additionally, data collected by researchers at the University of California Davis showed similar spikes in the levels of sulfur and silicon compounds, and certain metals, in aerosols. To better explain these data, as well as the unusual detection of 1,3-diphenylpropane, the presence of energetic nanocomposites in the pile at Ground Zero is hypothesized.
Conclusion : The presence of energetic materials, specifically energetic nanocomposites, at GZ, has the potential to explain much of the unusual environmental data seen at the WTC. Thermite, discussed briefly above, is such a pyrotechnic mixture that cannot be easily extinguished and is a common component of energetic nanocomposites. Unusually high detections of sulfur, silicon, aluminum, copper, nickel, iron, barium, and vanadium might all be explained byphysical release of materials from such energetic nanocomposites.
Additionally, the detection of 1,3-DPP at the WTC supports this hypothesis. Finally, the spikes in VOCs, detected by EPA on specific dates, are more readily explained as a result of short-lived, violent fires caused by energetic materials.
Josh Mitteldorf considers the implications at Op ed news for the theory that controlled thermite cutter charges were used to bring down WTC1.WTC2 and WTC 7 (the last some time after the BBC told us it had fallen down). According to FEMA, WTC 7 collapsed at 5:20pm on the afternoon of 9/11. Since British Summer Time is five hours ahead of Eastern Standard Time, the BBC reported the collapse of Building 7 at 4:54PM EST, a full 26 minutes before it collapsed.(You Tube video here)
