I know you guys think I have been slacking, but there are things in the works over here. Really. I mean it. You don’t believe me? I know you don’t… so here’s a sneak peak at my Revised WTC Demolition Theory Hypothesis. More careful study of the NCSTAR1 report (a troll suggested I do it) has turned up some interesting facts like:
1. the composition of the trusses themselves (no A-36 structural steel, but rather a combination of ASTM A-242 and an ASTM A-572 equivalent)
2. the number of the trusses (nearly doubled the 23,000 of my first estimate)
3. the existence of an ELECTRICAL WIRING DUCT that ran next to most of the trusses and embedded in the concrete once that was poured (very important for the DET CORD theory)
4. pictures of a few scraps of the trusses recovered from Ground Zero
Anyway, I am still working on it. So here are a few technical drawings that I have just completed showing in detail, what I think caused the destruction of the Twin Towers.
(see more details after the break)
Some revisions based on the NCSTAR diagram located on page 6. Notice the electrical ducts and the doubled trusses.
The composition of the trusses was not simply carbon and iron as has been suggested by many others. That would be the main composition of A-36 structural steel. But as NIST points out, in the fabrication process of the trusses, the company that made them substituted a higher grade steel, a HSLA steel, for the parts of the trusses that were to be comprised of A-36 structural steel. They also used ASTM A-242 steel in the trusses. This could explain the reports of silicone, sulfur, and various other metals found in the “iron rich spheres”.

The incredibly high temperatures required to create the spheres themselves as well as all the molten steel found under the rubble of Ground Zero can easily be explained by the use of PETN. PETN is commonly used in the demolition industry and it is more than capable of creating temperatures in excess of 7,050 degs. Fahrenheit. PETN is one of the most powerful high explosives used in the demolition industry. The application of the PETN filled DET CORD would be as simple as reaching up into the ceiling tiles on each floor, and running the DET CORD like an electrician pulls cable, in the pre-existing ELECTRICAL DUCTS. There would be no need for drilling or for finding a way to fasten the DET CORD to the underside of the metal floor pans. The installation would fast, simple, and could be disguised as a “cable upgrade” for the security system.
PETN – POWER INDEX OF 167 … AS COMPARED TO TNT’S 116
PETN – HEAT OF EXPLOSION VALUE OF 5794 kJ/kg RDX = 5036 kJ/kg
RDX – TEMPERATURE OF EXPLOSION = 4186 K = 7075 F
PETN – TEMPERATURE OF EXPLOSION > 7075 F
(The formula for kelvin to Fahrenheit is ((Kelvin – 273) * 1.8 ) + 32; note: 1.8 = 9/5.)
From the RJ Lee report:
In addition to the spherical iron and aluminosilicate particles, a variety of heavy metal particles including lead, cadmium, vanadium, yttrium, arsenic, bismuth, and barium particles were produced by the pulverizing, melting and/or combustion of the host materials such as solder, computer screens, and paint during the WTC Event.
Combustion-related products are significant WTC Dust Markers, particularly if seen in combination.
… The differences within the WTC Dust and typical background dusts include the fineness and evidence of heat…
… The amount of energy introduced during the generation of the WTC Dust and the ensuing conflagration caused various components to vaporize. RJ Lee
David Ray Griffin, one of the most respected people involved in the grass-roots investigation of the events of Sept. 11th, had this to say in his recent article, The Mysterious Collapse of World Trade Center 7, about the evidence of extremely high temperatures in the WTC 7 collapse…
The RJ Lee study also found that temperatures had been reached “at which lead would have undergone vaporization”– meaning 1,749°C (3,180°F).
Another study was carried out by the US Geological Survey, the purpose of which was to aid the “identification of WTC dust components.” Besides also finding iron particles, the scientists involved in this study found that molybdenum had been melted. This finding was especially significant, because this metal does not melt until it reaches 2,623°C (4,753°F). Griffin
More to follow later… just a sneak peak.
Oh, wait… as promised…
Even the NIST could NOT explain WHY there were NO LONG PIECES OF THE TRUSSES or even INTACT PIECES OF TRUSSES… the NIST report cannot explain this fact. Here are the only pictures of the trusses that I have been able to find. The 22 scraps found by FEMA…
Notice these pieces aren’t “crushed flat” like one would expect…
