NIST Refutes 9/11 Conspiracy Theories (National Institute of Standards and Technology)
EE Times ^ | 08/30/2006 | George Leopold

Posted on 08/30/2006 12:57:41 PM PDT by nickcarraway

The government is taking the unusual step of responding to conspiracy theories about the destruction of the World Trade Center.

The National Institute of Standards and Technology (NIST, Gaithersberg, Md.), which investigated the causes of the collapse of the twin towers, said Wednesday (Aug. 30) that it has posted a "fact sheet" addressing alternatve theories about the fires and collapse. Several academics have put forth a "controlled demolition" and missile attack hypotheses for the destruction of the towers.

NIST concluded after a three-year building and fire safety investigation that the towers collapsed after being hit by separate, fuel-laden aircraft flown by terrorists. The impacts severed and damaged support columns, dislodging fireproofing insulation and dispersing jet fuel over multiple floors of each tower.

The resulting fire, which reached temperatures as high as 1,000 degrees C, weakened floors and columns, causing upper floors to collapse after sagging and pulling inward on perimeter columns. "This led to the inward bowing of the perimeter columns and failure of the south face of WTC 1 and the east face of WTC 2, initiating the collapse of each of the towers," NIST concluded.

NIST's probe rejected claims that upper floors "pancaked" on top of lower floors, causing the collapses. Other investigations pointed to huge amounts of office supplies, especially paper, as a source of fuel that significantly raised the temperature of tower fires beyond those that jet fuel would normally burn outside of an aircraft engine combustion chamber.

"Both photographic and video evidence—as well as accounts from the New York Police Department aviation unit during a half-hour period prior to collapse—support this sequence for each tower." NIST concluded.

Far more controversial are theories about explosions inside the towers. Conspiracy theorists postulate that puffs of smoke seen at the time of each collapse are evidence of a controlled demolition. Critics of the official probe also cited seismic data they claim showed evidence of explosions just before each tower collapsed. Other theories alleged missiles were fired at the doomed towers.

While both NIST and the 9/11 Commission have dismissed these theories, U.S. officials have been compelled to address allegations widely disseminated on the Internet.

"NIST respects the opinions of others who do not agree with the findings in its report on the [World Trade Center] collapses," the agency said in a statement. "However, the WTC Investigation Team stands solidly behind the collapse mechanisms for each tower and the sequences of events (from aircraft impact to collapse) as described in the report."

Why no mention of the 47 central steel columns that were the main support for each tower?

That's the "strong central core" that was being talked about. See pic below:

But it seems perfectly obviously to me that if one building is pancaking from the top down, and another building is pancaking from the bottom up, that THAT is the reason you think the squibs, if they exist and if what they appear to be doing matters at all, may look like they're racing DOWN in the top-to-bottom collapse and UP in the bottom-to-top collapse. Doesn't it to

But the government itself has dismissed the so-called "pancake" theory. That's even in the NIST report posted on this thread.

"According to the project manager, Mr. DeMartini all those buildings were designed to withstand major impacts.....including jetliners and I'm sure falling debris."

Including impacts that damage major support structures?

Have you examined the photos of Bld. 7? The huge gaping hole in one side, the fire that burned for sometime that further damaged the building supports etc?

Neat! Well good luck too you. I am actually thinking of getting back into woodworking, especially after the last visit to the furniture store.

I did say "inexplicably". I think you're missing the point. The point is the photos themselves. Every freakin' member of the Bush admin. claims the government had never envisioned planes being used as weapons but here you have the Pentagon simulating the exact attack on 9-11 with models and pics being placed on a military defense website. Give me a break!

I'm sorry; I'm not buying this "nobody envisioned" B.S. It strains credulity.

My first go round on this, and I found it very unsatisfying.

I guess my post 170 wasn't clear enough. It's not photoshopped, but your reference to it proves nothing.

Oy. I never heard there was a "so-called pancake theory".

Okay, what do THEY call it when one floor drops onto the one below it, and that one falls onto the next , and those fall onto the next, etc?

I heard one structural engineer call it "telescoping", but more regular people seem to know what you MEAN when you say pancaking. What difference does it make what they call it? I'm describing what happened, not proving or disproving some collapse theory.

Stop it nitwit. Once the Effing towers started to fall it pancaked to the bottom. The NIST statement was that pancaking didn't cause the fall. You are a flipping ashwipe conspiratorial dipwit that doesn't have any concept of physics.

Anyway, I don't know what pictures you've seen of #7, but I don't know how you could look at any pictures of #7's southern face (short side of the trapezoid, remember) from the afternoon of 9/11 and not conclude that it was burning like a mofo.

If you are serious, I will find and post what few photos I have.

Yes I am very serious. I'm not trying to win an argument. If you have these pictures, please print them. I would love to take them to some of these 9-11 critics and ask them to reconcile them with their arguments.

I am also interested in the best websites that aim to debunk the "conspiracy theories". The few that I have seen have been sub par.

Here are the only pictures that I have ever been able to find on Google and none of them show these massive fires you are referring to.



The only photo that I did find that purports to show the southern side of building 7 on fire is the following, but it is unclear to me if this is fire or the dust cloud from the collapse of WTC Tower 1.


You would think if the southern face of the building was so dang bad off, the north side would indicate this as well (supposedly the pictures I posted above were close to the time of the collapse). What would keep such an inferno from spreading horizontally?

Give you a break? For what? Lack of reading comprehension? That exercise DIDN'T envision planes being used as weapons. It envisioned a commercial plane CRASHING in the Pentagon; not one being intentionally FLOWN INTO the building!

From the article (emphasis added):

Washington, D.C., Nov. 3, 2000 — The fire and smoke from the downed passenger aircraft billows from the Pentagon courtyard. Defense Protective Services Police seal the crash sight. Army medics, nurses and doctors scramble to organize aid. An Arlington Fire Department chief dispatches his equipment to the affected areas.

Don Abbott, of Command Emergency Response Training, walks over to the Pentagon and extinguishes the flames. The Pentagon was a model and the "plane crash" was a simulated one.

Get it? It was a crash, not a terrorist attack, and the plane "crashed" in the Pentagon courtyard, not into the building.

A plane crash makes a great disaster prep exercise, and has been (and is) used frequently. But it was not the only scenario in this exercise:

The Pentagon Mass Casualty Exercise, as the crash was called, was just one of several scenarios that emergency response teams were exposed to Oct. 24-26 in the Office of the Secretaries of Defense conference room.

On Oct. 24, there was a mock terrorist incident at the Pentagon Metro stop and a construction accident to name just some of the scenarios that were practiced to better prepare local agencies for real incidents.

The mock plane crash was as opposed to a mock terrorist attack. Note the number of casualties envisioned:

In this particular crash there would have been 341 victims.

Someone asked me to give some facts.  Her are some other "facts" that strain credulity:

http://www.11alive.com/news/usnews_article.aspx?storyid=42069

CBS News reported, meanwhile, that a passport belonging to one of the hijackers, Satam al-Sugami, was found on the street minutes after the plane he was aboard crashed into the north tower of the World Trade Center and before the New York landmark collapsed.

http://www.guardian.co.uk/september11/story/0,11209,669961,00.html

It started the day after the attacks on the twin towers, with the discovery of a flight manual in Arabic and a copy of the Koran in a car hired by Mohammed Atta and abandoned at Boston airport. In the immediate shocked aftermath of the attacks, these findings were somehow reassuring: American intelligence was on the case, the perpetrators were no longer faceless.

In less than a week came another find, two blocks away from the twin towers, in the shape of Atta's passport. We had all seen the blizzard of paper rain down from the towers, but the idea that Atta's passport had escaped from that inferno unsinged would have tested the credulity of the staunchest supporter of the FBI's crackdown on terrorism.

 

http://news.bbc.co.uk/2/hi/middle_east/1559151.stm

Another of the men named by the FBI as a hijacker in the suicide attacks on Washington and New York has turned up alive and well.[…]

Saudi Arabian pilot Waleed Al Shehri was one of five men that the FBI said had deliberately crashed American Airlines flight 11 into the World Trade Centre on 11 September.

His photograph was released, and has since appeared in newspapers and on television around the world.

Now he is protesting his innocence from Casablanca, Morocco. […]

He acknowledges that he attended flight training school at Daytona Beach in the United States, and is indeed the same Waleed Al Shehri to whom the FBI has been referring.[…]

Abdulaziz Al Omari, another of the Flight 11 hijack suspects, has also been quoted in Arab news reports.

Abdelaziz Al Omari 'lost his passport in Denver' He says he is an engineer with Saudi Telecoms, and that he lost his passport while studying in Denver.[…]

Meanwhile, Asharq Al Awsat newspaper, a London-based Arabic daily, says it has interviewed Saeed Alghamdi.

Khalid Al-Midhar may also be alive

He was listed by the FBI as a hijacker in the United flight that crashed in Pennsylvania.

FBI Director Robert Mueller acknowledged on Thursday that the identity of several of the suicide hijackers is in doubt.

But if you look at the 9/11 Commission report, on pages 38 and 39 in section seven (PDF) you'll see the same 19 hijackers without any suggestion that there's a doubt about there identities.

You know first you make comments with sexual overtones and now you think someone is trying to flatter you (I don't even know you). Are you sure that you're married and do you really want to be?

After seeing all of the leaks and leakers gain fame and notiority how can anyone brelieve that the people in such an imagined plot would keep quiet for five years and pass up the chance to be rich and famous? I know Washington, and that is not even a remote possibility. Nor is it conceivable that every expert would keep quiet about thing that are ony whispered among ignorati on late night radio. To me this is just a waste of time.
