2:05 in.See those huge steel beams that make up the walls of the towers?That's called a steel mesh..at least that's what the world trade designers called it.Look it up it's out there.
The buildings' signature architectural design feature was the vertical fenestration, the predominant element of which was a series of closely spaced built-up box columns. At typical floors, a total of 59 of these perimeter columns were present along each of the flat faces of the building. These columns were built up by welding four plates together to form an approximately 14-inch square section, spaced at 3 feet 4 inches on center. Adjacent perimeter columns were interconnected at each floor level by deep spandrel plates, typically 52 inches in depth. In alternate stories, an additional column was present at the center of each of the chamfered building corners. The resulting configuration of closely spaced columns and deep spandrels created a perforated steel bearing-wall frame system that extended continuously around the building perimeter.
Floor construction typically consisted of 4 inches of lightweight concrete on 1-1/2-inch, 22-gauge non-composite steel deck. In the core area, slab thickness was 5 inches. Outside the central core, the floor deck was supported by a series of composite floor trusses that spanned between the central core and exterior wall. Composite behavior with the floor slab was achieved by extending the truss diagonals above the top chord so that they would act much like shear studs, as shown in Figure 2-6.

Now 4-5 inches is long way from several feet

How can the top 15% of a 1360 foot skyscraper crush the rest in less than 18 seconds?
No need to debunk debunkers.

We should never tire of debunking the debunkers, no matter how inane it gets.

great, more oggidyboggidy nonsense to throw into the mess of 9/11. Fact 9/11 was not what it seemed, that much is obvious. IMO there are one to many mis/disinformists running around who are just making the situation worse for those who actually want to know the truth, guess thats the point.

This is a controlled demolition.

Of course, it's convenient that there is no sound in that clip...must be a copyright issue with the History Channel??
Because, for the thousandth time....CD of buildings and other structures involve VERY loud, very obvious sequential explosions...
loud as in audible, and obvious for the same reason...also obvious for the visual aspect. Most angles, depending on distance, can see the explosives going off.
Nothing like that was seen on ANY of the WTC buildings. Zero evidence for a CD.
Most of the WTC 7 shots were from a distance.
These were attested to in the case of the towers and in the case of WTC 7. You know that.

Are they absolutely without a doubt 100% sure that they did see a plane?
They really actually saw with their own eyes something that was 100 something stories up, going at 400-500 mph? I don't think so. I don't think that, at the time, they even knew what happened. It was probably when they got home and turned on the television and radios and heard that planes hit the buildings. Having heard that, they start believing that what they "saw" was an airplane.
Fire does take out buildings in controlled demolition. That and physical removal of many structural supports, and partial cutting of beams and columns.

If fire could take out steel and concrete buildings like a controlled demo..like building 7,fell straight down in seconds into a ready to go pile..then all the demolition companies would be out of a job.
