Major Firefighters’ Professional Journal Concludes That 9/11 Was "Explosive Demolition"

[munkle]

Thre firefighters are the ones who were closest. This could be trouble.

Built to last or built to fail: Could office fuel loads cause the complete collapse of WTC 7?

WTC 7, the third high-rise to collapse on 9/11, was located about 100 yards (91.4m) north of WTC 1, was a 47-story steel building, stood 610 ft. (186 m),

"“Sudden transition to freefall rules out a progressive collapse by fire or any other known natural mechanism other than explosive demolition.”

NY Fire Commissioner Chris Gioia: Controlled demolition

duh.

If it weren't, NIST would make public the models they used, rather than keeping them classified.

Then they would have fallen from the bottom and they didn’t.

Then they would have fallen from the bottom and they didn’t.

The Twin Towers were banana peel demolitions which are used for tall narrow buildings that could tip over if there is a misfire. Bottom -up implosions are more common.

You can see the Twin Towers are getting blown to fuk. This is not a "collapse."

Yes that was a nice touch. You saw the weight shift around the floors where you saw the molten steel dripping out the sides, exactly what steel-melting thermite charges would do. The melting core columns shifted weight to the perimeter columns so they bowed outwards, and gave the impression of an impending gravity collapse. But all the 70 floors beneath that were perfectly intact and undamaged.

No one is saying 9/11 was not an amazing piece of work.

German Minster of Defense Andreas Von Bulow:

"Planning the attacks was a master deed, in technical and organizational terms. To hijack four big airliners within a few minutes and fly them into targets within a single hour and doing so on complicated flight routes! That is unthinkable, without backing from the secret apparatuses of state and industry." Tagesspiegel, 13. Jan. 2002 German Minster of Defense Andreas Von Bulow

Running down steel beams? Where’d it come from?

Those Muslims have to be really pissed off now. Wasting a bunch of perfectly good suicide bombers on a couple of buildings that were already gonna be blown up by Elvis.

"As public awareness grows about the truth about 9/11, it serves to point out that many features of the towers' destruction fit perfectly with standard patterns of demolition. Evidence which at first seems puzzling is in fact consistent with known demolition techniques.


WTC 7 differed from Towers One and Two in that WTC7 was a traditional "bottom-up" implosion. The Twin Towers, on the other hand, exhibited the more unfamiliar pattern of a "banana peel" demolition, which starts at the middle or the top of a building and progresses downward. The below demolition in China shows the pattern of streamers of arcing debris that we see coming from the Twin Towers, as the cutting of supports begins high above ground level and works its way down.

Banana Peel Demolition in China next to Twin Towers


Banana peel demolitions are used for taller, narrower buildings, where there is danger of the building tipping over should the bottom be cut and the rest of the sequence not execute perfectly.

But first, just how does a demolition work? Students of the truth about 9/11 will not be surprised to learn that it is essentially the art and science of causing to happen what cannot happen without careful engineering: all structural supports in a building must be cut at essentially the same time, so that all pieces are falling at free-fall acceleration through thin air. It is a difficult undertaking to remove all supports nearly simultaneously in redundantly engineered modern high-rises, with extensive cross-bracing which transfers load from compromised members to sound ones. Even then, failed demolitions are not uncommon.

In the below images we see the principle support columns in the "core" of WTC 1, an extensively cross-braced steel assembly which served as the backbone of the towers, and held 70% of the weight.

Illustration of main support columns





One standard technique is the use of "cutter' and "kicker" charges, in which the first set of charges, the cutters, cut the steel beam supports at precisely timed intervals, and the kicker charge "kicks" the cut piece outward. In all the film evidence of the Towers' destruction, straight, cleanly cut pieces of steel beam can be seen spinning outward from the Towers at explosive speeds, across an area at least three times as long as the Towers are wide. Thirty foot, multi-ton pieces of steel beam and perimeter assembly were found nearly three football fields away from the nearest tower, and windows were blown out across the WTC. These startling facts cannot be overstated.

now you know why the FF's were under gag order.......~S~
