So how is the NIST so sure the insulation was even knocked off significantly? Surely, there isn't any evidence to unequivocally prove that the insulation from the floors that suffered the impacts was dislodged...so aren't they completely hypothesizing without a shred of actual proof? If so, does this "expert" theory sound all that solid and/or concrete if at the very foundation...we are working from a complete and utter assumption?
Argument from incredulity.
NIST doesn't make an unwarranted assumption. NIST observed the evidence and created a hypothesis. So far, there is absolutely no evidence that contradicts this. So far, no testing of the hypothesis has produced contradictory results.
If you have contradictory evidence or testing, submit it to a peer-reviewed journal along with an improved hypothesis. Otherwise, your complaining that you just don't like the work NIST has done is logically worthless.
So again - NIST's theory is that this falling building mass (upper floors above the impact) smashed down upon the lower floors causing them to pulverize into dust.
Strawman.
NIST never claimed that the building was pulverized to dust. The evidence is obvious and overwhelming that pieces of the buildings survived that were much larger than dust.
So, how can NIST even be all that certain, that the upper mass remained intact during the entire collapse? They can't...and it's just another critical point that is left up to complete speculation.
Strawman and Incredulity as well as being just plain wrong.
Even if the upper floors had disolved to dust (which they did not), that dust still existed. It had the same mass as the uncrumbled floors, it fell at the same speed and it had the same force. Take a ten pound brick and drop it on your head from twenty feet. Then repeat with a ten pound bag of sand. Report back on which one hurt more.
I, for one - will at least present this video, which shows the collapse of WTC 2:
I don't know the name of this logical error, but I know you're making one. You have fallen into the trap of believing that pictures and video give you more information than they actually do. All pictures are 2-D and one can only guess at depth. All of them are from only one angle and one can only guess at what is happening behind any opaque images. And all of them are of a dynamic event, leaving one to only guess what came before and after. Oh, they are also from very far away, have varying light intensity, may have camera artifacts built in, etc.
In this clip, you can clearly see that the critical upper mass of WTC 2 begins to fall over and to the side, just shortly after the collapse begins. A simple lesson in one of the fundamental laws of physics i.e. inertia - states that...A body moving on a level surface will continue in the same direction at a constant speed unless disturbed. So, following...SCIENTIFIC law, the upper mass will not and cannot move itself back to it's original position i.e. directly above the lower floors.
This is a perfect example of what was said above. You have been fooled by the video into believing that you see more than you do. It is mostly an illusion.
The top floors are, in fact, leaning, however, they are doing so almost entirely within the footprint of the building. As the steel weakened, it bowed inward. The building actually got narrower at the point of impact. This makes the lean above this narrow section look more dramatic than it was.
Also, as the exoskeleton was pulled inward, the top of the building twisted. This twisting also caused the illusion of a greater lean than really existed.
But, mostly, the towers were built around a central core with the floors tethered to it and only supplementally supported by the exoskeleton. As the core failed, it pulled the building above it in and down. This placed increased pressure on the core directly below, caused it to fail and continued to pull the building inwards towards the core. So, there really was a force working to straighten the buildings. The manner of the buildings' construction actually kept the top floors from toppling over like a tree and pulled them back into alignment.
The upper mass on WTC 2 was moving away from the lower floors at the time of its disappearance into the dust cloud, so we can reasonably conclude (backed with the LAW of inertia) that the critical upper mass was NOT a sufficient force in the collapse of WTC 2.
Your conclusary statements backed with no math whatsoever are, in all cases, wrong. The top floors were being pulled into the building as it collapsed from the core outward.
As regards sufficiency of force, you should look into exactly how many tonnes of explosives in how many places would have been required to duplicate the tragedy of that day.
As has been mentioned many times before, there were lots of reports of molten metal at the scene of the WTC Towers. We are all familiar with the pools below the rumble at ground zero, but there was also some molten metal seen pouring from the floors that were damaged during the plane impacts.
Both reports have been widely debunked. There is no credible report of pools of molten metal in the WTC debris.
NIST even confirms that molten metal was, in fact, pouring out of WTC 2 shortly before it's collapse.
"The composition of the flowing material can only be the subject of speculation, but its behavior suggests it could have been molten aluminum."
The NIST statement does not support your claim. You say that NIST confirms molten metal and the quote you offer specifically
declines to confirm it.
"Pure liquid aluminum would be expected to appear silvery. However, the molten metal was very likely mixed with large amounts of hot, partially burned, solid organic materials (e.g., furniture, carpets, partitions and computers) which can display an orange glow, much like logs burning in a fireplace." NIST FAQ
Hey, while we're at it...why don't we just claim that unicorns are likely to have collapsed floors 28-45 due to excessive gallivanting.
Your argument from incredulity has no weight. What logical, evidentiary reason do you have to deny that any aluminum would have been greatly contaminated with organic matter? Why should we disregard NIST's statements as ridiculous? Why should we equate contamination of aluminum with carpet, furniture, wallboard and human remains with the existence of unicorns? One phenomenon is well known, the other is known not to exist. They are not equal.
Anyway, let's just assume for a second that since NIST even admits molten aluminum is silvery and NOT red or yellow-orangish/red, that the molten metal isn't the aluminum from the plane
Unwarranted assumption.
This is where thermite comes into play.
What were the mechanisms used to trigger the thermite? How were they planted in the buildings? Who planted it? How did they know exactly which floors the planes would hit? How did the detonation mechanisms survive the plane crash?
So going back to my opening statement...what do plane impacts, thermal insulation dislodging and potential energy generated by falling building masses all have in common? THEY DON'T EVEN EXIST!
The planes never hit the buildings? That will be a relief to the families of the passengers. Shall I obtain a phone list on my own or did you want to call them yourself?
Jeez.
