Anyway you want to look at it jaydees the debunkers debunk themselves every time they claim it would have taken tons of explosives strategically placed on every floor to get a building the size of the towers to collapse, then out of the other side of their mouth claim for instance that flight 175 randomly striking between the 78th to 84th floors, randomly hitting different columns, caused every floor above it to come down.
A muddled view as is common for you HI.
the explosives contention IS NOT that of the debunkers. The amount of explosives used, calculated by debunkers relies on the contentions of the TM regarding the condition of the structure, the manner in which it collapsed and the description by the TM of events occuring during collapse.
The TM contends:
- the buildings were in good shape as far as load carrying capacity after the aircraft impacts.
YOU attempted to illustrate this notion by your out-of-context quoting of NIST's description of this.
-the buildings could only have been brought down in their own footprint as much as they were, by the planting of explosives in order to fail each floor in succession.
YOU have ignored this contention by the TM thus far in this thread.
-the buildings could only have collapsed at the rate they did by planting explosives within the building to fail each floor.
YOU have ignored this contention by the TM thus far in this thread.
-the so called 'squibs' are the direct evidence of explosives being detonated ahead of the outwardly visible collapse zone.
YOU have ignored this contention by the TM thus far in this thread.
So even if just your NIST collapse initiation hypothesis is correct then it must also be true that explosive like the aircraft on just a few floors could collapse up to twenty floors above it.
Incorrect again. NIST stated that the aircraft impact weakened the load carrying capacity of the building but that the building still stood. It was the further weakening by the resultant , immediatly ignited, widespread, multi-floor fires that caused initial collapse. You used the example of the Murrah building. It also did not collapse despite the 4 tons of anfo explosive used. It was a wreck surely, but it still stood even a week later and had to be brought down.
Collapse initiation I remind you, came a hour after the impact and that if YOUR contention of explosive use is correct then it occured then, and affected a building , at the level of the impacts, which was already weakened by the impacts. The aircraft impacts then of course were inflicted on a structure that was , at that time, still in pristine condition.
It does not however mean it would continue below the impact or explosives zone, or if it did for how long.
The NIST and debunker contention is, and the math that shows this (see Bazant for eg.), contend that gravity alone would account for global collapse after initial collapse. YOU contend that explosives are neccessary. YOU cite the fact that they are required in all 'normal' CD's by explosives. In those 'normal' CD's by explosive means there are indeed a lot of explosives loaded ONTO the columns AND there is significant pre-weakening of key structural members which again all leads to a TM requirement for more explosives(since pre-weakening is out of the question). The debunkers simply carry forth on the TM contention, and illustrate that this contention would require a lot of explosives.
You are welcome.
I did hear you say thank you , right?
YOU cannot have it both ways HI. You cannot claim that few explosives would be required but also that NIST is incorrect in stating that once initial collapse had taken place as it did that global collapse would ensue. If NIST is incorrect on that point then YOUR contention requires more explosives.
And none of this even gets near the main conspiracy I've also heard which is thermite. Thermite that debunkers are quick to point out doesn't explode.
Again we come to the TM contention of co-ordinated failing of the columns. Thermite is unreliable as far as timing goes. It is also unreliable in causing a quick and accuratecutting of large cross section , vertical columns. Thermite also has its own markers. First of all the amount required to significantly weaken, let alone cut through a thick, vertical column is quite large. YOUR contention is that little material would have to be smuggled in in the preceeding few days(or a year if bomb sniffing dogs are as useless as you wish them to be). Thermite would also absolutly have to be mounted ON the columns. Your contention previous to this page was that this was not neccessary(since you would have to explain how this was accomplished).
The fire that supposedly caused the collapse initiation by weakening steel in the NIST version also made no noise after the impact of the plane. But according to NIST caused at least in the case of the flight 175 impact zone about 20 floors above it to collapse..
NIST and many other fire engineering tests illustrate that office fires can and do weaken stell to the point of causing significant deformations of load carrying members. In addition, the impacts had already compromised the capacity of the structure, AND in 'normal office fores the conflagration begins small, spreads about one floor, eventually spreads to adjacent floors again starting small on those floors and spreading to larger areas WHEREAS IN THE TOWERS, it was within seconds of impact a large area fire on each of several adjacent floors.
So keep talking.
You debunk yourself.
In short it was the cumulative effect of several insults to the impact floors that caused initiation and the manner of construction(long span, trusses and tube in tube) that allowed this initial collapse to keep progressing.
