FDNY Chief Daniel Nigro's statement on WTC7

Status
Not open for further replies.
Why is it nonsense?

from an elevator mechanic in the WTC on 9.11.01:

http://www.thrnewmedia.com/adayinseptember/jones.htm


What we heard was 6 and 7 car free-falling from the 107th floor and they impacted the basement at B-2 Level. And that’s the explosion that filled the lobby within a matter of two or three seconds, engulfed the lobby in dust, smoke.

What exactly does this have to do with WTC 7 being cleared for demolition, collapse, whatever?

How is that contradictory? Silverstein suggested they pull the firefighters out when he was told it might not be saved. looks like he verified it. I would also think that Nigro didn't make the decision on his own.
How is it not contradictory?

Nigro says he made the decision on his own

1) Fire Chief Frank Fellini: "So for the next five or six hours we kept firefighters from working anywhere near that building, which included the whole north side of the World Trade Center complex. Eventually around 5:00 or a little after, building number seven came down." (Interview, 12/3/2001)

FDNY Lieutenant Robert Larocco - "We walked over by number Seven World Trade Center as it was burning and saw this 40-plus story building with fire on nearly all floors."

FDNY Lieutenant James McGlynn - "...Just went you thought it was over, you're walking by this building and you're hearing this building creak and fully involved with flames. It's like, is it coming down next? Sure enough,

Fire Captain Ray Goldbach: "There was a big discussion going on at that point about pulling all of our units out of 7 World Trade Center. Chief Nigro didn't feel it was worth taking the slightest chance of somebody else getting injured.
Silverstein:

"I remember getting a call from the, er, fire department commander, telling me that they were not sure they were gonna be able to contain the fire. And I said, “You know, we’ve had such terrible loss of life, maybe the smartest thing to do is… is pull it.” Er… and they made that decision to pull and then we watched the building collapse."

So we have 'reliable reporting'... that 7 was afire on nearly all floors, fully involved in flame, creaking and ready to fall?

We have warnings at least from 12 noon and I recall there were news reports of 7 imminent collapse as early as 11am... to
"about a half an hour later it came down." and "they made that decision to pull and then we watched the building collapse."

The reports do not match the visual evidence they do not match NIST's report and they do not agree with each other by a country mile.
 
Elevators are equipped with several independent safety features specifically designed to prevent them from plummeting, even in the event that all the cables are cut.

Were these features designed to withstand the impact of jet planes at 500pmh?

I couldn't find a single instance of a death in a plummeting elevator since 1940.

Woman drops to her death in lift plunge

This lady in the Empire state building miraculously survived the free-fall. Curiously, the actual cause of the free-fall was plane crashing into the building.

When the plane struck the building she was on the 75th floor and was thrown to the ground by the force of the impact, as well as sustaining burns from the burning airplane fuel. Having survived a plane crash into the building, the danger was far from over however. The rescuers decided to get her to the ground floor as quickly as possible so she could be taken to a hospital for treatment. They decided to use the elevator to take her down the 75 stories. What they did not know was the elevator they were using to transport her in was damaged by the plane crash. The elevator cables were almost set to break free. They placed Oliver in the elevator and, when the doors closed, the cables snapped. Oliver and the elevator plunged 75 floors to the basement but, miraculously, she was not killed. Thousands of feet of elevator cable had fallen to the basement before the elevator and this “softened” the impact. Once again, Oliver had to be rescued, this time from the bottom of an elevator shaft among heaps of twisted metal. Seriously injured, she lived and to this day holds the record for the longest survived descent in an elevator accident. This would remain the only known instance of a free-fall of a modern cable-borne elevator, until September 11, 2001.

That something happened to the elevators is clear. There are several reports of explosions/balls of fire spewing from the elevator shafts in both towers. Unless the several levels of inherent safety features failed in each elevator, and in each elevator-shaft significant quantities of jet-fuel survived while burning long enough to make the hundred-floor trip down, I'd say the destruction of the elevators is more evidence of explosive involvement, unless there's a reasonable explanation for why the built-in safety-features failed. If you were to cut all the cables in any other elevator in any other building, the result, when that elevator reached ground level, would certainly not be a fiery explosion. Remember, in the video presented above with the young blond firefighter and the older black firefighter discussing the lobby-explosion they experienced, they were already in the process of assembling in the lobby with the intention of commencing a rescue. That puts them well outside the time-frame of an elevator plummeting as a result of the plane-crash severing cables.


You have the man in charge of the elevators in question, there on scene, describing what happened...and yet somehow you disregard it. Just to clarify- you do not believe this guy for whatever reason?

What we heard was 6 and 7 car free-falling from the 107th floor and they impacted the basement at B-2 Level. And that’s the explosion that filled the lobby within a matter of two or three seconds, engulfed the lobby in dust, smoke....so it came down like a bomb, and that’s what it sounded like

http://www.thrnewmedia.com/adayinseptember/jones.htm

Clearly the safety features of the elevators DID fail when sliced through with a jet airliner. That IS a reasonable explanation. If an falling elevator was being followed by a blast of burning jet fuel- there would be a fiery explosion. How do you explain all the burns and smell of kerosene which are consistent with jet fuel bursting forth from elevator shafts?

So we know for a fact that elevators crashed down despite their safety features. What is more likely- that the safety features failed due to an impact with a jet plane? Or that explosives were used to cause the safety features to fail almost simultaneously with the impacts of the planes...and give the that it was appearance of jet fuel assisted.??

Remember, in the video presented above with the young blond firefighter and the older black firefighter discussing the lobby-explosion they experienced, they were already in the process of assembling in the lobby with the intention of commencing a rescue. That puts them well outside the time-frame of an elevator plummeting as a result of the plane-crash severing cables.

That could be. I am unclear as to where they were and when. Is it possible they were massing in the lobby of one building when the other was hit and sent debris crashing into it? Their description is identical to the accounts of elevator damage in the lobbies. It highlights that there were many things that could have happened that could have been misconstrued as a "bomb".

It was Grieves who brought up the idea that elevators crashing to the lobby was "nonsense"- I simply pointed out the bunk.
 
Elevators are designed to not allow doors to open unless there is an elevator in place. The planes CUT all the cables, the fail safes are not designed to handle that.

ConsumerWatch.com reported that elevator accidents that result in death are very rare -- about 27 a year -- though injuries from elevator accidents affect about 10,200 people a year.
...
A 2009 report by Occupational Health & Safety attributes the rarity of elevator fatalities to "intricate, redundant, and regulated safety features built into every elevator." Elevators typically have four to eight times as many cables holding them up than they actually need, and they also have automatic braking systems near the top and bottom of the shaft, backed up by electromagnetic brakes. Finally, "at the bottom of the shaft is a heavy-duty shock absorber system designed to save passengers if all else fails," the report stated.

That is pretty well discussed in another thread to be honest and it does seem a bit off topic.

https://www.metabunk.org/threads/wtc-rate-of-fall-rate-of-crush.1142/

However, I would ask if you have any examples of a steel framed high rise building which collapsed at freefall acceleration, which were not intentionally demolished or otherwise 'blown up' in some way, i.e. collapsed by fire?

I have never personally seen any building demolished at all.

However that doesn't answer the question, and I am unaware of any answer being given in any other thread.

But history both pre and after 9/11 shows us that fire, even far more intensive and far longer duration, results in a collapse speed of 0 feet per second, i.e. they do not collapse.

Certainly I have seen discussion here in other threads why buildings did NOT collapse - however that is begging a point.

My question is why a building that DOES collapse would do so at something other than freefall speed if it was not deliberately demolished.

And it was not at free fall speed. Say I claim I make $100,000 dollars a year on a loan application and it turns out that I only make $70,000, can I claim that that is 'almost' 100 grand? Nope. Then why do the truthers keep claiming freefall speed for the entire collapse when it wasn't. Some things fell off at nearly free fall speed, but that is not uncommon. Gravity is a constant.

Gravity is indeed a constant and that is why what you are discussing here is freefall acceleration, not freefall speed. That there was a period of freefall acceleration in the descent of WTC 7 is not in question. Exactly why there was a period of freefall acceleration is in question, as this shows that there was absolutely no structural resistance in play at that point. 2.25 seconds of no structural resistance at all in the collapse of an absolutely massive building is a powerful reason for a forensic investigation to fully explore and eliminate the possibility of some kind of accelerant being involved.

Of course, NIST did not do this which is why the emphasis must be placed very firmly on the word "should" in Chief Nigro's statement "That [the NIST] report should explain the cause and mechanics of the collapse in great detail". The report should have eliminated the alternative hypotheses exhaustively (saying "there wasn't a big enough bang" is really pathetic) before presenting a fire-induced progressive collapse as the most likely or reasonable conclusion, but then this was a conclusion that NIST reached through the examination of precisely zero physical evidence.
 
Now please explain how an accelerant increased the rate of collapse.

Accelerant is the description given in the "gold standard" of fire investigation manuals, NFPA 921, as in
NFPA 921 19.2.4 -"Exotic Accelerants"

which NFPA 921 specifies should be tested for in cases of "high order damage"

Thermite is specifically mentioned

You move logically from the statement that the building was on fire to assume what you seem to think is the obvious conclusion that it must inevitably have been utterly and totally destroyed in a matter of seconds exactly how? :(

So you are saying that it was thermite that took it down. That dog don't hunt, buddy. It would have taken a large amount of thermite to do it, and since it doesn't like to cut through a vertical surface, some method would have had to be devised to keep it in place long enough.

The police dept doesn't do a DNA study of some equine dung at a crime scene to see if the criminal escaped on a zebra or a unicorn.

Appeal to incredulity. This should have been a forensic investigation. The best forensic fire investigation protocol in the US, accepted by courts throughout the nation, does not quibble on imagined technicalities in a case like this. It is clear and unequivocal that accelerants should be tested for if damage is severe.

Isn't this what you would expect from an investigation: a thorough and scientific undertaking, that makes no assumptions at the outset and examines the evidence before drawing conclusions?

The police dept doesn't do a DNA study of some equine dung at a crime scene to see if the criminal escaped on a zebra or a unicorn.
Here we go with the arbitrary and conclusion-assuming metaphors again. You don't construct a logical argument out of conclusion-assuming metaphors I'm afraid and you certainly can't assume that fire will inevitably bring a massive building straight down in a matter of seconds.

So: You move logically from the statement that the building was on fire to assume what you seem to think is the obvious conclusion that it must inevitably have been utterly and totally destroyed in a matter of seconds exactly how? :(
 
You were the person that brought up thermite as the cause. Thermite is NOT used for this purpose because it is not suitable.

Just because you can't understand how it could, doesn't mean that the experts and others can't.

And now the bare assertion fallacy. I didn't bring up thermite specifically, I mentioned it in reference to NFPA 921 which Chief Nigro of all people would have reason to expect NIST to have followed as a bare minimum of its investigative process. But NIST let him down.

Just because you can't understand how it could, doesn't mean that the experts and others can't.
This statement makes no sense, coming from you. It is most applicable in support of my position: just because you can't understand how accelerants might be applied in a case like this doesn't mean that experts can't.

Again, you are making an extraordinary logical leap along the lines of "fire in building = complete and total destruction of the building in a matter of seconds, including a period of free-fall", and therefore you think it's fine to ignore investigation protocols.

If you're comfortable with that kind of "logic", that's fine by me, but you have to accept it's not really logic at all.
 
You can stop the silliness. You brought it up. To assert that mentioning didn't mean you thought that was the cause of the collapse, is only fooling you.

I need to go back and see what was said about that time of 'free fall' you are asserting happened. I know that I have seen it debunked.

Nonsense. The point is made. Chief Nigro would doubtless have expected NIST to have followed the NFPA 921 code at an absolute minimum when he made his statement at the start of this thread. NFPA 921 is clear and unequivocal in demanding testing for accelerants in the event of high-order damage, and mentions thermite as an example of an accelerant you asked to be defined.

Even if you manage to suggest that the free-fall period was slightly less than free-fall (and I have evidence that it was indeed free-fall, but it involves measuring the speed of descent in the video evidence, and I know your computer is too ancient to play... videos) then the point remains undebunked.
 
So you have 'discovered' something that NO ONE else has noticed. Sorry if I don't consider that any evidence.

I am not the only person that can debunk it. Why are you acting like I am? Convince Mick or Jazzy that your 'evidence' is correct, and then I will discuss it. Until then, you can talk to someone else.

Of course not. Freefall has been an issue from the start, although it took David Chandler to force NIST to acknowledge it and expose the risible sleight of hand it undertook with its collapse timings to try to obfuscate the fact (youtube link provided here for anyone that has a computer that was built this century):

I'll take that as an admission of defeat on your part. :)

Why don't you join me, Cairenn, in calling for Chief Nigro's expectations of NIST's WTC 7 investigation to be fulfilled by a new investigation that follows rather than ignores the clearly defined and forensically necessary requirements of the NFPA 921 code that he probably knows by heart?

Freefall has never been an issue except for truthers. There's nothing at all unreasonable with the exterior of the building collapsing at essentially free fall acceleration. It's basically what you would expect if the interior of the building collapsed first, and then the exterior buckled over several floors.

And we know you don't think the investigation was good enough. Unfortunately it seems nobody with any real experience in the matter agrees with you. NIST explained why they did what they did:

http://www.nist.gov/el/disasterstudies/wtc/faqs_wtc7.cfm

16. For its study of WTC 7, why didn’t NIST follow the National Fire Protection Association (NFPA) guidelines for conducting a fire investigation?

NFPA 921, “Guide for Fire and Explosion Investigations,” is a recommended methodology for optimizing investigations. NFPA 921 acknowledges that each investigation is unique, and that some investigations will require broader procedures than it can accommodate. This was especially true for NIST’s WTC investigation, which responded to events that were much more than typical fires or explosions.

However, NIST’s WTC 7 investigation did follow the core tenet of NFPA 921, which is the application of the scientific method. The investigation was carefully planned, sources of information were identified and contacted, the building fire and collapse event and the investigation were documented, available evidence was obtained (including documents about the design and construction of the structure), and the origin of the fire was determined based on images, laboratory testing (conducted for the towers, but applicable to WTC 7), and mathematical analyses.

Additionally, in its study of WTC 7, NIST considered all available data and evaluated a range of possible collapse mechanisms: uncontrolled fires on the tenant floors, fuel oil fires, hypothetical blast events, and fires within the Con Ed substation. NIST developed a working hypothesis, modeled the fires and the building, and then used the models to test the hypothesis against the observed behavior of the building. This approach is fully consistent with the principles of scientific inquiry.

You asked me not to bring the subject up and then banned me for a month minutes later: before I'd even realised you'd sent me a message. Of course there are plenty of people who have issues with the NIST WTC 7 report and it most certainly does not follow the principles of the scientific method.

You appear to think mere plausibility is all that's required, and plausibility is far from universally agreed. However, I am happy to drop the subject if you could link me to what you consider the best explanation for freefall here on your site.

I've had a little search but all I can find is the usual bluster.
 
The exterior columns buckled, so offered a relatively small resistance for a period of time. That's it. Now if you can debunk this, then just start a thread with your debunking.

http://www.nist.gov/el/disasterstudies/wtc/faqs_wtc7.cfm

11. In a video, it appears that WTC 7 is descending in free fall, something that would not occur in the structural collapse that you describe. How can NIST ignore basic laws of physics?

In the draft WTC 7 report (released Aug. 21, 2008; available athttp://www.nist.gov/el/disasterstudies/wtc/wtc_draftreports.cfm), NIST stated that the north face of the building descended 18 stories (the portion of the collapse visible in the video) in 5.4 seconds, based on video analysis of the building collapse. This time period is 40 percent longer than the 3.9 seconds this process would have taken if the north face of the building had descended solely under free fall conditions. During the public comment period on the draft report, NIST was asked to confirm this time difference and define the reasons for it in greater detail.

To further clarify the descent of the north face, NIST recorded the downward displacement of a point near the center of the roofline from first movement until the north face was no longer visible in the video. Numerical analyses were conducted to calculate the velocity and acceleration of the roofline point from the time-dependent displacement data. The instant at which vertical motion of the roofline first occurred was determined by tracking the numerical value of the brightness of a pixel (a single element in the video image) at the roofline. This pixel became brighter as the roofline began to descend because the color of the pixel started to change from that of the building façade to the lighter color of the sky.

The approach taken by NIST is summarized in NIST NCSTAR Report 1A, Section 3.6, and detailed in NIST NCSTAR Report 1-9, Section 12.5.3.

The analyses of the video (both the estimation of the instant the roofline began to descend and the calculated velocity and acceleration of a point on the roofline) revealed three distinct stages characterizing the 5.4 seconds of collapse:

  • Stage 1 (0 to 1.75 seconds): acceleration less than that of gravity (i.e., slower than free fall).
  • Stage 2 (1.75 to 4.0 seconds): gravitational acceleration (free fall)
  • Stage 3 (4.0 to 5.4 seconds): decreased acceleration, again less than that of gravity
This analysis showed that the 40 percent longer descent time—compared to the 3.9 second free fall time—was due primarily to Stage 1, which corresponded to the buckling of the exterior columns in the lower stories of the north face. During Stage 2, the north face descended essentially in free fall, indicating negligible support from the structure below. This is consistent with the structural analysis model, which showed the exterior columns buckling and losing their capacity to support the loads from the structure above. In Stage 3, the acceleration decreased as the upper portion of the north face encountered increased resistance from the collapsed structure and the debris pile below.

You ask why NIST did not follow NFPA 921. So I give you NIST's answer. You disagree with the reasoning they use, but it's still the reasons why they did what they did.

Anyway, if you have something to add, take it up in your thread. It's off topic here.

And I thought you were going to start a thread explaining why free-fall was impossible in WTC7?

In point of fact I have already pointed out the myriad flaws of reasoning in NIST's justification for not following NFPA 921 months ago (unfortunately somewhat edited by a moderator recently).

If "debunkers" didn't keep copy-and-pasting the same passage in response to my points as if those criticisms hadn't been made, my responses wouldn't become so repetitive. But then I suppose Mick wouldn't have an excuse to ban me with virtually no warning at all.

And you may believe you have the "FACTS" on your side, Cairenn, but this is not the case. You should start by acknowledging the best you have, if you believe in NIST, is a hypothesis. It is a hypothesis derived from a investigation that examined precisely zero physical evidence, postulates a great deal that is supposed to have happened for which there is not even any visual evidence, and depends considerably for its justification on a computer "simulation" that does not simulate the video evidence and cannot be verified.

A hypothesis is not "FACTS".

To prove this point, let me ask you: can you give one actual reason why NIST should not have followed the NFPA 921 code in the case of WTC 7 that stands any rational scrutiny at all? All NIST says is it requires "broader accommodations". How is this a justification for not applying the NFPA 921 code in respect of the scientific method as its application is defined in the code (which NIST did not do)? It is actually saying nothing at all.

These are some of the things NFPA 921 codifies in respect of fire investigations and the scientific method that I mentioned before (again, ignored by "debunkers").

Do you think Chief Nigro would have expected the NFPA 921 code to be applied in this case? I do. What actual substance is there to NIST's excuse for not doing so?

ps. I picked up this super-annoying use of italics from Jazzy. I may start using bold soon too.

Edit: Oh look, I did.

Believe it or not, I have a life, family, job, and some very serious concerns to address at the moment. Amusing myself with the denizens of this forum is a kind of distraction from them for me, but I can't have fun 24/7. Don't worry, I'll start the thread when I've had time to analyse the text from NIST you copied-and-pasted point by point (as I said, I have analysed much of it already and that was just ignored).

I also need to read through some of what's been said before, so all in all it may be a little while.

Big Brother will get back to you, Mick.

Edit:
Of course, you locked that thread weeks ago.

Elevators are designed to not allow doors to open unless there is an elevator in place. The planes CUT all the cables, the fail safes are not designed to handle that.
Your own excerpt would argue with you.
A 2009 report by Occupational Health & Safety attributes the rarity of elevator fatalities to "intricate, redundant, and regulated safety features built into every elevator." Elevators typically have four to eight times as many cables holding them up than they actually need, and they also have automatic braking systems near the top and bottom of the shaft, backed up by electromagnetic brakes. Finally, "at the bottom of the shaft is a heavy-duty shock absorber system designed to save passengers if all else fails," the report stated.
Seems as if the safety features are specifically designed for the event of all cables being cut, as was stated in the link I posted.

Were these features designed to withstand the impact of jet planes at 500pmh?
Can you explain how a plane impact on the uppermost floors of the buildings would plausibly disable every braking system and render the shock-absorber so entirely ineffective as to not only kill the occupants, but also result in large and fiery explosions which decimated the lobbies/basement levels?

You have the man in charge of the elevators in question, there on scene, describing what happened...and yet somehow you disregard it. Just to clarify- you do not believe this guy for whatever reason?
I'm not disregarding what this guy has to say, or calling him a liar. But what he has to say isn't nearly so 'smoking-gun' as you imply. He describes hearing a sound, likely elevators on a fast descent, he describes an explosion afterward that wrecked the lobby. That's his personal experience, and I believe it. None the less, you can't present his explanation of that explosion being the result of the elevators explosively hitting the bottom floor as some sort of professional assessment he gained at the time through his experience as an elevator technician. He makes it pretty clear he didn't know what he was hearing or why the lobby blew up. He states he was told what had happened later. The explanation he presents is one he was given and accepts, not the independent conclusion of an expert on the scene or something.

We heard the explosion and within a matter of seconds after that impact, I heard – and as well as everybody else heard – this noise, this increasing sound of wind. And it was getting louder and louder. It was like a bomb, not quite the sound of a bomb coming down from a bomber. It was a sound of wind increasing, a whistling sound, increasing in sound.

I’m looking from the lobby up to a mezzanine area or the second floor where they lined up all the people to go up to the rooftop, and I’m looking up expecting something, building parts to be coming down, because I wasn’t quite sure what that noise was.

But I found out later, when the plane came through the building, it cut the hoist ropes, the governor ropes, of (the) 6 and 7 cars, which was the observation cars.

Every night they would park those two cars up on the 107th floor. At the time the plane impacted B Tower, the observation deck wasn’t open yet, which was another life-saving factor. At the time it impacted the building, they hadn’t opened the observation deck.

Had they, there would’ve been many, maybe another 1,000, 2,000 people on the rooftop, because it was a clear day. It was a beautiful day.

What we heard was 6 and 7 car free-falling from the 107th floor and they impacted the basement at B-2 Level. And that’s the explosion that filled the lobby within a matter of two or three seconds, engulfed the lobby in dust, smoke.

If an falling elevator was being followed by a blast of burning jet fuel- there would be a fiery explosion.
So jet-fuel, acting as the powder in a musket, blasted the elevators from top to bottom, chasing them with a fiery wall of pressure down 90 floors?

Clearly though a heavy duty shock absorber (which is only a few feet high) is not going to do anything for a fall over anything over a few tens of feet. Certainly not for a fall from the 106th floor. A car travelling at 100 mph cannot safely stop in six feet.

And you seem to be conflating two things - the fireball type explosion, and the impact of the elevator falling. Think about them as two different events.
 
Is there any experiment or any real evidence that there would be enough oxygen or fuel left after the initial explosion to have this suppose fireball descend 106 floors and still have the ability to decimate the lobby? It sounds ridiculous just saying it...if we are basin everything on real evidence show some that this is even possible with some real backing in another realistic situation
 
When a fire in closed area runs out of oxygen, it may go out, but as soon as there is available oxygen, it will restart. In fact that is used in the ceramic technique called raku.
 
Jomper, you know there's not going to be another investigation of WTC7.
I'd settle for the release of the complete datafiles of the NIST "simulation" at this point. I don't think there's a single "debunker" on this site who can defend the "public safety" argument for classifying that information and maintain a veneer of independent thought or credibility. I know Jazzy has, but I think gerrycan showed him just how mistaken his dogmatic defences of the NIST report have been.
Certainly not one with more physical evidence from WTC7 examined.
Ah, so you accept that there is physical evidence from WTC7 that NIST could have examined? Perhaps you would argue that physical evidence is not relevant to a forensic investigation for some reason? Would you accept that physical evidence is critical in forensic investigations in general, or can you point to another forensic investigation that came to credible conclusions without examining any physical evidence at all?
So what is your goal here?
I'm fascinated by disingenuous "debunkers". For example, I recently asked: what is the actual substance of NIST's excuse for not following the NFPA921 code in the case of WTC7? NFPA921 makes it clear what following the scientific method in fire investigation actually means and quite obviously it means testing for accelerants in the event of high order damage. NIST's stated "reasoning" for not doing so is meaningless, wouldn't you agree?
You've already stated your point literally hundreds of times, and ignored the answers given an equal number of times.
I haven't ignored the answers: I've pointed out how hollow they are. That's quite different. NIST may say it has followed the scientific method in investigating WTC7 but this does not in fact make it so. If I point this out, what I get is endless copy-and-pastes of NIST's claim to have followed the scientific method. And this from people who claim to have reason on their side. As I say, it's fascinating.

Why don't you ask the NIST that? None of us were a part of them. The EXPERTS didn't and all the backseat drivers think that they know more. Hmm, experts or non experts, who should I believe?
 
Well don't bother calling the electrician, mechanic or plumber, cuz you can 'think for yourself'.
That's an absurd metaphor: NIST's "reasoning" for abandoning the NFPA921 code in the case of WTC7 is rendered in plain (if meaningless) English, and plain expression rather than shaky metaphor is the medium of rational discussion.

However, if your property suffered a massive and mysterious electrical, mechanical or plumbing failure and the electrician, mechanic or plumber you called ignored the standard and rationally-expressed manual for identifying the cause of the disaster and couldn't tell you why, would you aggressively defend their methods to your neighbour if they said it was obvious they'd done a very dodgy repair job? ;-)
