Safe Mode: On
Chemical Traces of High Explosives in WTC Debris

Josh Mittledorf – Op Ed News August 5, 2008

The standard way to demolish a steel-framed building is to apply cutter charges to the supporting beams. The cutter charges consist of finely-powdered aluminum mixed with iron oxide, with added sulfur. This mixture contains both fuel and oxidant – it needs no air – and it burns hot enough to melt steel. The trade name for this product is “Thermate.”



Girder from the WTC, note the neat diagonal cut
There is a science to placing the charges in such a way that the building falls inward. It requires a great deal of expertise to keep a tall building from toppling over sideways.

Many scientists and engineers have looked at the way the WTC towers fell and remarked that it had the appearance of controlled demolition. The buildings collapsed symmetrically, and fell straight down. The speed of the fall indicated that the buildings were collapsing unimpeded. They must have had the “legs” simultaneously pulled out from under them, because a layered collapse from the top down would have taken several minutes, whereas the observed collapse took place in less than 20 seconds.

Another anomaly in the WTC collapse was the violent explosions. Firemen reported earthshaking blasts from the basement before collapse, and the impact areas in the upper floors of the buildings exploded just at the onset of collapse. Jet fuel burns but cannot explode.

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, before he was fired for raising these and other questions.

Fires at the WTC site persisted for weeks after 9/11, despite firefighters’ use of water and chemical extinguishers to smother the flames. This suggests that it was a fuel-oxidant mixture that was burning. Pools of red-hot molten iron could not have been caused by burning jet fuel or building materials, because these burn at a much lower temperature than steel melts.

Ryan’s evidence consists in traces of 1,3-diphenylpropane as well as sulfur and particulate matter, reported by the EPA to have appeared in spikes continuing as late as March, 2002. Ryan believes that these came from brief, intense fires ignited by the molten steel when it came in contact with yet-unburned plastic building materials during the clean-up process.

  • If any of you Tina's used a cutting torch you would know that the torch blows the melted steel away from the cut and not puddle on the cut like this. One second thought, please stay away from welding equipment, you might light your tampons on fire.

  • i dont give a fuck what your beliefs are, you have to admit this seems odd. how in the hell in the mass of twisted and burning debris can you have multiple perfectly straighht cuts, defies logic. I am also tired of this shit but the more you read the mor eit DOESNT make sense.

    • Angular cuts were made by demolition steel workers during cleanup. See picture:

    • Easy. It was done after as part of cleanup. They had to cut up big pieces into smaller pieces to they could remove the debris.

      People who believe otherwise are delusional or fail to check out facts.

      There is no evidence of thermite or thermate.

      There were not pools of molten iron.

    • I'm going to have to call bullshit on that one. While I believe that 9/11 was an organized "inside job", you are correct in saying that these pictures were taken after beams had been cut during the removal of the wreckage.

      This is where your correctness ends. There ARE videos of the construction foreman at ground zero telling a reporter that the guy driving the backhoe cannot dig any deeper due to red hot molten metal in the debris pile.

      Don't say there isn't any thermite or the More..

    • There were hot spots in the debri, but no pools of molten metal like truthers would have you believe. The pictures truthers show that they say indicate large pools of molten metal were debunked as nothing but lights shining down a hole.

      I do not need a chemistry degree to analyze that the data truthers show proving thermate is weak. All the compounds they say show indications of thermate are all compounds used in the contruction of the building. The proportions are all wrong for thermate, and More..

    • I'm sorry if it sounded like the cleanup crews knew thermate was there, not what I had intended as I was reffering to the pools of molten metal that I have seen in several different sources, one the mentioned video and two a sattelite photo taken over the area.

      If you have information that this is incorrect, I'd like to know the source of it so I can confirm it on my own. So my question to you sir is where did you get the information that NO pools of molten metal were found? That is contrary More..

  • Not to say that the terrorist did not also placed explosives in the building too. What do you think of that theory? Huh huh?

  • The picture is shortly after the collapse, therefore the smoke and the firemen. I won't go into the white hot steel weeks after 9/11, or the fused concrete/steel chunk in lower floors.

    • It is discovered, even you know it it put when enough people denies it, it is like it is now.
      ANd also political goals by other countrys have effect.
      But politicians from seven country, including germany, russia, GB has sayd that there is much more than people thinks. Some have said diractly that it was inside job.
      There is over 1000 clear evidence that it was inside job, and how many against it? Zero.
      And people still thinks that some ragheads from caves did this. lmao
