Continuation: 'What about building 7?'

Gypsum dust would certainly prevent oxidation and flame due to combustion by cutting off the oxygen to the fire. Things would then cool quickly due to conduction as they were also being contacted by cooler items during the collapse.

Explain to me then why charcoal will burn under plaster or Paris, dried gypsum at 600C,
You do not understand that drywall gives off steam, to prevent fire by cooling, while dried gypsum plaster of Paris has almost no effect.
Since the dried Gypsum and dried concrete would be the most widely spread dust, like the dried gypsum itself your theory does not hold water.
 
Gypsum gives off water when heated that is the limit to it's fire squishing capabilities, dry gypsum dust would have no effect on the fire, or flammable material.
Tony has no Idea of how gypsum cools and suppresses fires, by cooling by giving off steam.
Charcoal will burn buried in plaster of Paris, gypsum heated to 600C, with all the water driven out.

I know gypsum contains moisture and that is the big reason it is fire resistant.

However, I am talking about heavy layers of gypsum dust choking off the oxygen, not cooling the fire.

Much of the initial gypsum dust in the North Tower was also from areas above the fires.

Nice try though.
 
10 seconds after collapse initiation the North Tower was one big dust cloud and it would have been very thick in the plan of the building.
*sigh*
Not particularly relevant. Debris was ejected from the building. We cannot know which spark ignited the fire. It's possible what started fires in WTC 7 was not from the impact areas... so what? Evidence points to a mechanism that is related either directly or approximately to the collapse of WTC 1.

There were no fires left on the north face when the North Tower collapsed.

whatever little had fire...

South face (right), West Face (left)


In addition not much of that material made it to WTC 7. WTC 7 was in the outer part of the outer damage radius shown by FEMA. I also have never seen the perimeter fall over towards WTC 7 like you say you have. Do you have video of that?
Clearly enough to do damage and create a sufficient fire hazard; one far better supported than the arson/floating thermite that you've adopted for the last year

Tony: See this picture?

Tony, Here is what Building 7 looked like at the moment the debris from the Tower collapse smashed against it. Debris top to bottom, left to right, from a building whose smoke plumes were miles long. Come on, how can you seriously propose that such a catastrophic collision as this be completely without any heat, when an overheated coffemaker was enough to bring down a big piece of TU Delft?

Just one of the emergency generating units shorting out could have created the fire, and gypsum soaked in diesel fuel from the ruptured supply line on the roof tanks would certainly produce enough fuel vapor to ignite.

The idea of arson in world trade 7 is a Joke tony is playing on himself.

Tony is literally blowing smoke. I'd like to see him cough up a reference that shows gypsum dust cuts off oxygen when it is widely scattered. Tony needs to do a coverage map, show the density of gypsum and the amount of burning material, show that it completely covers and cuts off the oxygen from all the burning material. You are right, it only takes one burning element to contact one burnable element to continue the fire. Tony is making a bare unsupported assertion, and one that makes no sense whatsoever. If he can't figure it out himself, and doubly since he is no expert in this matter, he needs to consult legitimate fire experts.
 
Oystein, it is a shame you and GlennB can't provide real mechanisms and arguments to show that WTC 1 could have caused the fires in WTC 7 as I understand you really want to believe it.

The mechanism is as follows:

  • Hit facade with HUGE stretches of steel wall assemblies weighing hundreds of tons and thus slice open a HUGE gash down the middle stretching many many floors and going deep inside the building.
  • Liberally dump buckets of embers and burning stuff from largest and worst fire NYC had EVER seen in its history into gash
  • Wait

I actually think the logic shows the fires in WTC 7 had to be started by arson and I have given those reasons, which are much more than the hand waving that the fires were big in WTC 1.
What you call "logic" most people would call "feverish dreams" or "wishful thinking".

It is a virtual impossibility for items from a natural fire to stay hot while being bathed in gypsum dust and in contact with cooler items during the collapse to then also have flown the 350 feet from WTC 1 to WTC 7 and also gotten into some relatively small openings in the building and start fires on ten floors.
Are you saying such an obviously FALSE thing on purpose, Tony? That would make me rather angry?
Or are you calling liars the many fire fighters on the scene who have seen and described the HUGE GASH that went down the middle of the south face of WTC7 and was anything but a "small" opening? Or do you simply forget about the HUGE GASH?

The building's exterior was not flimsy and it was not flammable like the plastic on vehicles. Your argument that WTC 7 was more in the line of fire than the Verizon or Post Office buildings, as an excuse for why it caught fire and they didn't, is also poor.
Tony, much of the four facades of WTC7 peeled outwards towards the four sides, normal to the building footprint, right? These walls, where they toppled, did not topple diaginally to the faces, or did they? Hence, for a reason and in fact, the toppling walls created a HUGE GASH in the south wall of WTC7, but for the same reason and in fact did not open a huge gash in the Verizon or P.O. bldg., or did they?

The infrared aerial photos showing surface temperatures of 1,300 degrees F five days after the collapses on the plans of WTC 1, WTC 2, and WTC 7 is enough to tell me the sub surface had unusual extreme heat and that was not caused by the fires in the buildings although logic would say it had something to do with the collapses because it was generally just under the collapsed buildings. You are only kidding yourself if you think otherwise.
The floor slaps generally just dropped straigt down, correct?
Most of the combustible contents of the towers would be expected to drop straight down with the floor slabs they were, would they not?
The non-combustible walls on the other hand could be expected to have fallen and rested more to the side and outside the footprints, don't you think?
As a matter of observed fact, the WTC1+2 walls did in fact land mostly outside the footprints, did they not?
So it is no real wonder that fires within the debris would mostly be fed by combustibles concentrated within and near the footprints, or am I saying something wrong here, Tony? Please tell me exactly where I am wrong?
Hydrocarbon flames can be hotter than 1,300 degrees F, or can they not?
So how about the simple theory that the infrared cameras simply saw scattered fires on or very near the ground?

Many recovery crews walked atop the rubble piles. They did not wade through molten steel. To think temperatures were hellish just beneath the surface with steel-melting temperatures is a perversion of the witness accounts and a sick fantasy. To think that thermite would have been able to make the pile so hot for weeks is extremely stupid and reveals a crass lack of understanding of simple thermodynamics - once you disperse the hundreds of tons of thermite that truthers dream about in their feverish wet dreams, they'd not be able to burn long or raise temps much. What a stupid stupid stupid stupid stupid idea!

There were no fires left on the north face when the North Tower collapsed. Edna Cintron was standing in the hole made by the plane. So why would you think whatever little had fire would be on the perimeter at the north side? ...

:mad::mad::mad:

Tony, please read the following line very carefully:





Edna Crinton jumped to her death.







Please read it again:

Edna Crinton jumped to her death.

And again:

Edna Crinton jumped to her death.



Got it by now? Three times more won't hurt:

Tony, Edna Crinton jumped to her death!
Tony! Edna Crinton jumped to her death!
Tony! Listen up! Edna Crinton jumped to her death!!




Now sit a minute and ponder:





Why would Enda Crinton jump to her death if the fires were so small and insignificanct on the north side, and eventual collapse of the tower an obvious impossibility?

Please give us a full explanation of the FULL account of Edna Crinton's experiences and actions there in the north wall gash!

But it doesn't seem that the reasons you've given are very convincing, at least the way you've presented them, so perhaps it would help if you actually show your logic in a more formal and complete form, including all premises and conclusions. That would make it easier to judge whether the premises are sound and the inferences are valid, wouldn't it?
 
Gypsum dust would certainly prevent oxidation and flame due to combustion by cutting off the oxygen to the fire. Things would then cool quickly due to conduction as they were also being contacted by cooler items during the collapse.

Gypsum is component of the FIT 5 fire supression device . This is dinner plate sized device which when thrown in a burning room expells a powder which
suppresses the fire long enough for fire fighters to enter and extinguish the
fire

https://www.facebook.com/ARASafety?sk=notes

The gypsum powder works by disrupting the chemical reactions of the fire -
the oxidation reactions which sustain the fire

It is not because of the steam liberated from the gypsum - though that probably helps

We carry one of these devices on every chief's vehicle and fire apparatus

Works best in confined spaces (attic, basements, etc)

Potassium carbonate.

http://firelink.monster.com/products/products/588-ara-fit-5

within seconds the FIT-5 releases a wispy cloud of potassium carbonate, a flame retardant that suppresses combustion and disrupts fire at the molecular level.

Gypsum is calcium sulfate dihydrate.

Do you have a reference stating gypsum?
 
Oystein, it is a shame you and GlennB can't provide real mechanisms and arguments to show that WTC 1 could have caused the fires in WTC 7 as I understand you really want to believe it.

I propose the same mechanism by which your flaming thermite or molten steel crossed the gap and set cars on fire in Barclay St. Now you tell us what that mechanism was.

It is a virtual impossibility for items from a natural fire to stay hot while being bathed in gypsum dust and in contact with cooler items during the collapse to then also have flown the 350 feet from WTC 1 to WTC 7 and also gotten into some relatively small openings in the building and start fires on ten floors.

Time from collapse onset to debris impact on various parts of WTC7 was a few seconds. How much cooling of debris substantial enough to create the damage photographed below do you suppose happened in that time? You have no clue about even the most basic facts of fire and heat.



Your argument that WTC 7 was more in the line of fire than the Verizon or Post Office buildings, as an excuse for why it caught fire and they didn't, is also poor.

No, fact is that WTC7 did get hit much harder than those other buildings and incidental that its facade was more likely to be penetrated

You might be having trouble following along.

I am taking about the dust being very heavy over the plan of the building. There weren't many survivors there. The dust would have been thinned by orders of magnitude away from the plan of the building.

You're grasping at straws, here. This gypsum seems to have whatever property suits you at the time.
 
We have heard that, supposedly, the thermite that destroyed the WTC twins, burned "vigorously", perhaps even "explosively". We learned that it was scattered among the dust in chips not significantly larger than 1 mm.

Such specks of thermite, if they were burning when they dust started dispersing, would have burned out within a very small fraction of a second, upon which, we are told, the reaction products are further dispersed: into microspheres, much much smaller than 1 mm, in the case of iron; and even smaller fume (so small Harrit et al never found any!) in the case of the aluminium oxide. Such burning thermite dust , and its residues, would have cooled to very near ambient temperature long before hitting the ground.

Had the thermite not already burned when collapse ensued and it started being dispersed into the dust cloud, then nothing could have ignited them later.

Slowly burning pieces of hydrocarbon would have stood a much much better chance of staying aflame for the perhaps 15 or 20 seconds it took for them to travel to some adjacent building and settle there on a stack of office paper.

They appear to have some reddish regions and some grey regions, which we all recognise as characteristic of military grade nanothermite.

Dave
That's not a tractor either.
It has no engine and why does it only have one light.
You can see that blade is made out of wood.
