"... unzip theory is a cover IMHO for the official version and explains NONE fo the annomalies - not the pyroclastic cloud; not the molten metal; not the ejected beams; not the explosions seen and heard; not the location of GPS-autopilot-guided planes into the WTC 1 and 2; and on and on. His is a post-facto excuse for the official pancake theory - only in his varient the members 'unzipped' and then pancaked. It defies what the evidence is and worse it defies PHYSICS!."
My theory is not *unzip* in either case. Never used the term nor is how I proposed the collapse occurred an unzippering of anything.
My theory DOES suggest an explanation for the huge dust clouds. They arose post collapse driven by 2 main factors... the extreme heat that was generated by the friction of communition of the materials which heated the air and billows up... much the way hot gas and smoke rise up from any fire. The second cause of the motion of these clouds was the fact that the collapse pulled a negative air pressure above (behind) it as it came rapidly down... at about 65 mph or so
causing cooler clean air to rush in and down... like the are air pulled in behind a speeding car. This air of course was stopped by the hot dusty debris pile and disbursed laterally carrying the light hot dust with it which heated the air and caused it to billow outward. Boyle's gas laws at work.
The identification of kind of molten material is imprecise at best. In the south tower the color cannot be used because the images are no color corrected, ther was dust in the air, refraction and a low sun angle all of which would change / influence the color of materials seen. This is no different from the effect of a yellow, purple, orange or red sky.. or even blue related to sun's angle and atmospheric conditions (dust etc.). You can find images on the www of waterfalls which appear orange as a result of optics... and no one would claim that the river was molten steel from that image. If the material pouring out was aluminum, for example, it would mean much lower temperatures. You can't identity chemicals from *uncontrolled* images.
The same applies to the metal below grade. But here the images are few and it's mostly testimony. We don't know the quantity or how long this lasted. Red hot metal is not liquid metal. Beams were not dripping liquid metal. I've seen no images of the end of a beam turning to liquid and dripping.
The NASA imagery DOES show 3 concentrated locations of extreme temps. My hunch is that the elevated temps were the result of the heat released from friction as the materials were ground up. You had hundreds of thousands of tons of materials grinding and colliding and abrading and this releases heat... just as file metal does. Lots of heat. Perhaps this heat became concentrated and insulated by the pile. There is also the possibility of exothermic reactions between ground building materials.. rust, alum, GWB (sulfur) water, pressure and so on. The so called meteorite is the result of the natural process of pressure acting on materials in the presence of water and ground up portland cement and GWB. If the heat was caused from friction of destruction of the slabs etc. then it would be expected to produce similiar signatures when a threshold is reached. Small structures collapsing don't present those threshold conditions... and many don't even collapse... such as bldgs 5,6,7.... which where destroyed from falling debris and fires... not self collapse.
Yes there were many explosions heard that day... all sorts of electrical gear and mechanical equipment was exploding when the system went outside spec.... overheated fire extinguishers... electrical transformers and so forth. There was a huge explosive sound down the street from me 2 weeks ago when a relatively small utility pole mounted transfer exploded. People rushed into the street thinking it was a bomb.. as they are trained from TV and Hollywood to associated loud explosive sounds with bombs... not exploding electrical equipment.
My theory is not a pancake theory for the collapse of the twins. It does not propose entire slabs coming un connected and falling in sequence. The theory was nicknamed ROOSD by someone else.. runaway open office space destruction... and refers to the FLOW and crushing of the floors in sequence by a growing and gathering mass of floor and other building rubble. The facade was not exploded off, but lost it lateral bracing from the floor destruction and was developing an increasingly exaggerated slenderness ratio and became unstable and susceptible to the lateral forces of the growing debris rubble / avalanching inside the *caging* of the facade.. as the pressure exerted by grain on the walls of a silo. The facade was pushed over, burst at it seams, fell or toppled away in panel configurations from a single 10'x36' panel to multiple ones which were as high as 12 floors and almost as wide as the tower itself. Of course this was not organized but violent and chaotic.
Nothing I have proposed defies evidence of physics. To the contrary it is based ON physics, engineering (applied physics) and the mappings/observations of the movements seen... and the rubble found. Physics tells us that the columns could not be crushed. And they weren't... the frame broke at the weakest points - the joints and splices which were bolted together... when subjected to excessive lateral forces and the structure's materials and their loads were disengaged from their load paths... and were free to act (gravity and F=MA) on the frame's joints.
It's certainly a good hypothesis that the planes were on some sort of autopilot or pre programmed flight path. This is entirely possible with the technology which existed at the time. The ROOSD collapse theory is only about threshold conditions manifesting in the twin towers which led to the destructive unstoppable ROOSD process once begun. That process could be initiated by exploding some of the columns or cutting them with devices. But there is evidence of this sort of intervention. There is evidence that the planes destroyed columns... reducing the columns available to support the floors above the crash zone... added some quantity of jet A fuel and fires to the remaining columns. With the loss of some columns at the strike zones the remaining ones carried additional redistributed loads effectively reducing their reserve strength... a double whammy... additional redistributed loads and lowering or strength from heat.
The collapse of the top of WTC 2 shows bucking in the remaining core columns in the region of the plane strike (*horseshoe column* is one example). This extreme example of buckling shows that the lower portion was still restrained laterally and that extremely loads presented... the result of loss of strength of the remaining core columns. The *horseshoe column* was one of the last remaining column in the core region of the strike zone and it could not support the entire load (100,000 tons) of the 32 floors above and folded like a a piece of clay or rubber. That's physics! Now 32 floors came crashing into the lower 78... and ROOSD was on!
