Some Misunderstandings Related to WTC Collapse Analysis

[Albert Doyle]

I don't think I saw your observation that no firefighters reported thermite in the stairwells.

There was only one radio transmission from firefighters who were near fires, and that from the South Tower three minutes before it fell, when chief Orio Palmer said they had reached the fire on the 78th floor and said they could knock it down with two lines. Thermite very likely would have been used on critical joints and wouldn't have been anywhere near the stairwells.

I beg to differ. A simple view of a cross-section blueprint of the tower would show the stairwells were mixed in to the core columns. The You-Tube video I linked showed that thermite burns with extreme sparkling intensity and smoke. If there were thermite packs in the columns they would have been seen burning for a few seconds and would have raised a burst of radio reports of thermitic fires in the stairwells by the firefighters who were trained to notice such things. Not a peep.

The columns were certainly not involved in the collapses

You've been arguing they were. They would have to be by science. How could they not be? The North Tower, for instance, probably had a good percentage of the core cut through because of the center hit of Flight 11. I also wonder if a direct hit on a floor pad might push the whole pad through the core laterally like a cutter. The transfer of mass would be huge with a speeding 767.

and the only plausible explanation I can think of is controlled demolition with devices eliminating their ability to provide structural resistance. In addition to the lack of column involvement and no deceleration problems for a natural collapse in the North Tower there is also video evidence of focused and concentrated blowouts which can only be from squibs. See this short video http://www.youtube.com/watch?v=hSApOavkHg8

I don't mean to start any thread problems but that video is laughable. Any fool can narrate a video to see and say what he wants. I heard a voice assuring me of things he wanted to see in that video. What I saw in that video fit exactly the collapse dynamic I tried to explain in my previous posts. First the controlled demolition people are saying there was thermite residue found in the wreckage. Yet here we have the narrator telling us a series of timed explosives charges cascaded in sequence down inside the building. So which one is it? Funny how that cascade happens exactly in synch with the pancaking floor pad theory. What CD proponents fail to fathom is the accelerated compressed air blast phenomenon that would collapse the floors faster than gravity and create all those visual clues the narrator is calling signs of explosions. This force would blast the core columns and the outer frame as you are seeing happen in the video. The outward force seen in those explosive dust bursts is something that would, by science, unzip the outer frame. A study of modern explosives shows that their components can be traced in wreckage residue. As I've already explained the unique hanging floor pad design with an inner core and outer frame may explain the lack of deceleration in the North tower. There was some delay in the initiation of the collapse where that deceleration could have occurred according to the design of the tower, and I don't see any detonation flashes in those cascading explosions.

Don't you understand that the building got stronger as you moved down the tower? It was a virtual pyramid strength wise. The columns under the 28 story load on the South Tower were built to withstand an average of four times the load above them, just like the columns under the 12 story load on the North Tower were built to withstand an average of four times the load above them. The further down you went the bigger the columns got to handle the bigger load above them.

You obviously didn't absorb what I wrote before. Did it ever dawn on you what your video is showing is exactly the collapsing floor dynamic I spoke of where extreme air blast pressure caused by floor pads displacing air under extreme weight appeared as explosions and crushed the inner core as it progressed downward? Not only would this downward progressive dynamic occur faster than gravity but it would create results that were identical to what you see in the collapsing tower. What we are talking about here isn't a sturdy pyramid of structure under the collapsing section but a funnel of force contained by the outside frame that transferred extreme energy down the column in a unique phenomenon caused by the tower's hanging floor design. A pyramid doesn't have a huge structural void like the towers did. What we are talking about here is the isolated point where that extreme air blast pressure is turned laterally and focused on the columns in a direction where they were vulnerable to lateral forces they weren't designed for. While the vertical resistance of the columns may have been designed for 4 times overkill they were not designed for a massive force cutting against them laterally on an individual floor basis. You are looking at that lateral force in your video. It isn't explosives. It's extreme, blasting compressed air pressure.
