UPDATE – a reader’s comment has inspired me to put up earlier 3d models that I created to better illustrate how I believe the det cord was used (H/T BuelahMan) see below
In a recent interview with Tom Sullivan, Richard Gage asks him about Brent Blanchard’s comment that the Towers couldn’t have been demoed because there would be “miles and miles of det cord” lying around afterward. Brent Blanchard knows all too well why this is a dishonest statement and Tom Sullivan did nothing to correct the misinformation. Det cord is a high explosive, used in the demolition industry to link cutter charges and to simultaneously blow up various structural elements of the building being brought down. In short, there would be no det cord lying around because the det cord itself is part of the demolition process… it blows up.
Watch this video for a good explanation of what det cord is and at the end they show it demo a concrete slab that is about 5″ thick. It is my theory that det cord was used to pulverize the floor systems of the Twin Towers during the demolition process. Hundreds of “electricians” were working in the Towers prior to Sept 11th on a project to rewire the security system. Det cord looks like any other fiber optic or CAT 5 cable.
the video doesn’t allow embedding (damn corporate network pricks) so when you click on it, you will see a link to the Youtube channel)
In my “Demolition Theory Hypothesis” I show how the placement of the det cord under the floor pans and up inside the dropped ceilings would pulverize the 110 concrete floors of each tower, then I also detail how linear shaped “cutter charges” would then cut the 47 steel columns inside the core of the towers and how the “kicker” charges would have detonated pushing the cut columns out of the way of the remaining demolition (some ended up shooting some 600 ft into other buildings)
This next video shows how linear shaped cutter charges and kicker charges work.
This is an original drawing I did. it is of a cross-section of a typical section of the Twin Towers, to scale, and as you can see, I have labeled everything detailed in the videos above. It should be noted that I just found these videos and did not view them prior to publishing my hypothesis.
Update – It has been brought to my attention by BuelahMan (H/T) that the difference here is that the det cord in the video was actually embedded in the concrete by means of drilling long holes or channels through the 5″ slab and that would make it much more effective. BuelahMan is absolutely correct.
The following images are taken from an article I wrote called Sneak Peak: Revised Demolition Theory Hypothesis . The first image is taken from the NCSTAR investigation page 6. It describes how the floor sections for the Twin Towers were actually constructed. They were put together and welded in a shop then shipped to the Twin Tower construction site where they were then set in place with other floor sections by crane (please see the Aug. 2009 article of mine called The 6,000 for more details and construction photos of these pre-made floor panels being installed in the Trade Center)

There at the bottom of the image you can see what it calls out as an “electric duct”. That is an open channel covered by a metal plate set at the same level as the corrugated metal floor pan. Each of these pre-made floor sections had 3 (three) of these electric ducts roughly 6 (six) feet apart. When the floor system was put in place and all the floor sections welded together, they would pour the concrete floors over top of all this and the electrical ducts would be actually up inside the 4″ of light-weight concrete.
The following image is of a 3d model I created based on the Twin Tower architectural drawings and the NCSTAR drawings. It is to scale (click on image for a larger view)
As you can see, when the concrete was poured over the floor system it would have gone down into the lower channels of the corrugated metal floor-pan but not inside the electrical duct, thus if the demo team had used these ducts to run their det cord, it would have been UP INSIDE the concrete floors, much like the video above, and therefore been much more effective as a shattering agent in pulverizing the 100’s of thousands of tons of lightweight concrete in the Twin Towers.
Lastly, just for scale, I offer two images: the first is a scale 3d model (my own) of a pre-fab floor system ready for installation and an image of the installation process at the World Trade Center.
