All these experts would have had to been part of any conspiracy theory


Why was there any need to have an expert committee we just needed Sandman and his one liners. So simple, so logical Sandman.


 

you can't argue with the most basic principle of physics...

it was not free fall speeds, but you have a boat load of engineers that aren't to happy with the governments explanation, many fire fighters as well... we see fires and see buildings fall for a living, WTC7 was allot more damaged than most of the angles that you see but there is zero shot of the whole thing falling at the same time like that...zero

BMA is a zionist. Only a zionist would be that stupid.

I'm not sure how Hutch's "research" comprised of anecdotal evidence of exterior damage can explain how that center column popped and made that building fall into its imprint. How did damage to the exterior of the building damage the interior? It didn't.

Furthermore, how was the Verizon building left unscathed if WTC took on so much supposed exterior damage. The idea of WTC being terminally damaged while Verizon sits unscathed is ludicrous. And we are supposed to be the crazy ones?

A building DAMAGED ON THE OUTSIDE ON ONE SIDE, has the center column pop first?

TOWER7

Diagram 1—Typical WTC 7 floor showing locations of columns (numbered). The buckling of Column 79 was the initiating event that led to the collapse of WTC 7. The buckling resulted from fire-induced damage to floors around column 79, failure of the girder between Columns 79 and 44, and cascading floor failures. (Credit: NIST)

5. How did the fires cause WTC 7 to collapse?

The heat from the uncontrolled fires caused steel floor beams and girders to thermally expand, leading to a chain of events that caused a key structural column to fail. The failure of this structural column then initiated a fire-induced progressive collapse of the entire building.

According to the report's probable collapse sequence, heat from the uncontrolled fires caused thermal expansion of the steel beams on the lower floors of the east side of WTC 7, damaging the floor framing on multiple floors.

Eventually, a girder on Floor 13 lost its connection to a critical column, Column 79, that provided support for the long floor spans on the east side of the building (see Diagram 1). The displaced girder and other local fire-induced damage caused Floor 13 to collapse, beginning a cascade of floor failures down to the 5th floor. Many of these floors had already been at least partially weakened by the fires in the vicinity of Column 79. This collapse of floors left Column 79 insufficiently supported in the east-west


The unsupported Column 79 then buckled and triggered an upward progression of floor system failures that reached the building's east penthouse. What followed in rapid succession was a series of structural failures. Failure first occurred all the way to the roof line—involving all three interior columns on the easternmost side of the building (79, 80, and 81). Then, progressing from east to west across WTC 7, all of the columns failed in the core of the building (58 through 78). Finally, the entire façade collapsed.

 What is progressive collapse?

Progressive collapse is defined as the spread of local damage from a single initiating event, from structural element to element, eventually resulting in the collapse of an entire structure or a disproportionately large part of it. The failure of WTC 7 was an example of a fire-induced progressive collapse.

Progressive collapse did NOT occur in the WTC towers, for two reasons. First, the collapse of each tower was not triggered by local damage or a single initiating event. Second, the structures were able to redistribute loads from the impact and fire-damaged structural components and subsystems to undamaged components and to keep the building standing until a sudden, global collapse occurred. Had a hat truss that connected the core columns to the exterior frame not been installed to support a TV antenna atop each WTC tower after the structure had been fully designed, it is likely that the core of the WTC towers would have collapsed sooner, triggering a global collapse. Such a collapse would have some features similar to that of a progressive collapse.

Some people have said that a failure at one column should not have produced a symmetrical fall like this one. What is NIST’s answer to those assertions?

WTC 7's collapse, viewed from the exterior (most videos were taken from the north), did appear to fall almost uniformly as a single unit. This occurred because the interior failures that took place did not cause the exterior framing to fail until the final stages of the building collapse. The interior floor framing and columns collapsed downward and pulled away from the exterior frame. There were clues that internal damage was taking place prior to the downward movement of the exterior frame, such as when the east penthouse fell downward into the building and windows broke out on the north face at the ends of the building core. The symmetric appearance of the downward fall of WTC 7 was primarily due to the greater stiffness and strength of its exterior frame relative to the interior framing.

 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 at https://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.

Did investigators consider the possibility that an explosion caused or contributed to the collapse of WTC 7?

Yes, this possibility was investigated carefully. NIST concluded that blast events inside the building did not occur and found no evidence supporting the existence of a blast event.

In addition, no blast sounds were heard on the audio tracks of video recordings during the collapse of WTC 7 or reported by witnesses. According to calculations by the investigation team, the smallest blast capable of failing the building's critical column would have resulted in a sound level of 130 decibels (dB) to 140 dB at a distance of at least half a mile, if unobstructed by surrounding buildings. This sound level is consistent with a gunshot blast, standing next to a jet plane engine, and more than 10 times louder than being in front of the speakers at a rock concert.

For the building to have been prepared for intentional demolition, walls and/or column enclosures and fireproofing would have to be removed and replaced without being detected. Preparing a column includes steps such as cutting sections with torches, which produces noxious and odorous fumes. Intentional demolition usually requires applying explosive charges to most, if not all, interior columns, not just one or a limited set of columns in a building.

. In June 2009, NIST began releasing documents in response to a Freedom of Information Act (FOIA) request from the International Center for 9/11 Studies for "all of the photographs and videos collected, reviewed, cited, or in any other way used by NIST during its investigation of the WTC building collapses." One of the items released, a video obtained from NBC News, shows WTC 7 in the moments before it collapsed, then cuts to the collapse already in progress, with the building's east penthouse “disappearing” from the scene (as it had already fallen in the intervening time). Other videos of the WTC 7 collapse show the penthouse falling first, followed by the rest of the building. How does NIST explain the difference between the NBC News video and the other videos?

The video footage released under the FOIA request was copied from the original video exactly as it was received from NBC News, with video documentation of the WTC 7 east penthouse collapse missing. The footage was not edited in any way by NIST.  

NIST received videos directly from many different sources during its technical investigation of the collapse of World Trade Center 7.  Videos were logged into a database as they were received and were accessible only to those working on the investigation.  NIST protected the integrity of the original videos at all times.  Many of these videos are available at https://www.nist.gov/el/disasterstudies/repository_home.cfm.

Would WTC 7 have collapsed even if there had been no structural damage induced by the collapse of WTC 1?

Yes. Even without the structural damage, WTC 7 would have collapsed from the fires that the debris initiated. The growth and spread of the lower-floor fires due to the loss of water supply to the sprinklers from the city mains was enough to initiate the collapse of the entire building due to buckling of a critical column in the northeast region of the building.

Oh so some office supplies on fire took down WTC 7?

Thanks BMA. What a load of utter bullshit.

How was the Verizon building left unscathed?

it would not have fallen all at one time, level on both sides the whole way down, im sorry but thats bullshit

BMA, read this https://en.wikipedia.org/wiki/Operation_Northwoodsand explain what I pointed out in this post.

The CIA gave Al-Qaeda and Osama bin Laden $3 BILLION dollars.
Israelis were caught on 9/11with a Truckload of Explosives under George Washington Bridge.
The 911 hijackers were of Saudi Arabian decent.
The two biggest Middle Eastern allies are Israel and Saudi Arabia.
Without 911 they couldn’t have gone to war with Iraq and Afghanistan.
There was never any evidence at all to go to war with Iraq, period.
The war in Iraq was about money, oil and for revenge for saddam threatening daddy.
Billions is government contracts and to set up a base for a war with Iran.
The US has a base in Iraq, Afghanistan, and guess which country is between them? Iran!
It’s about colonialism, money, oil, lithium, minerals, industrialism, drugs and a platform for war with Iran.
War is a multi-billion dollar business.
I don’t hate America or our troops, you do. I don’t want moms to feel what it feels like for their kids to die for colonialism, money, oil, lithium, minerals, industrialism, drugs and a platform for war with Iran.
Why people are mad at 911 conspiracy theorists?
I'm not a conspiracy theorist, I'm a truth seeker.
They should be angry with our government for using Americans and young kids as pawns for colonialism, wealth, and power.

Don’t question civilian people, question the government.

The problem I have with those so-called experts is that they already had preconceived notions.  

People have to let patriotism go and let go of the idea that the US government is righteous. People have to let go of the idea that the US government is not capable of committing mass genocide. People have to let go of everything the media tells you. People have to let go of all of the things that you were taught to believe in school.

People have to let go of everything they were taught to believe in. Unless people are willing to see the truth, there is no amount of evidence I can show you to change your mind.

You think the CIA, FBI, Dept of Defense, and others don’t have the capability of accomplishing an engineered series of explosions?

In a building occupied by occupied in part by the CIA, FBI, Dept of Defense, and others, you think they don’t have the technology required to prepare it for demolition?

I’m sure the CIA, FBI, Dept of Defense, and others know how to use Thermite.

WTC7 free fall
https://jonas61.unblog.fr/files/2009/10/untitled.bmp

I’m not saying I am sure of a conspiracy, I’m just saying don’t believe what the government tells you. They are put in place to lie to us and the US has been at war for 200+ years. The US runs on war. Without 911 there could be NO war with Iraq or Afghanistan.

+1 to Money for linking to Operation Northwoods

now google the Gulf of Tonkin

false flags...all of it

19 Saudi nationals with box cutters and hijacked 767's and 2 hours were able to get past the DoD, the US military, NORAD, and NATO

funny how none of us believe government statistics on the economy, job numbers, green energy, or anything else as we know there is an agenda yet these muslims did it because they hate that we are a "free" people and we all eat this shit up

war is big business and is a racket. the patriot act was written in 1995 by Joe Biden among others. Afghanistan has 90% of the world's poppy fields which GW Bush ordered specifically not to burn them (this is how the taliban made their money). our CIA guards them.
https://www.youtube.com/watch?v=N_54LJMwG4E

War is big business...debt and bombs enslave generations to bankers. Importing heroin is big business.

Our government runs guns to Mexican gangs and allows them to bring them across our border!!!! (Fast and Furious)

the same AG who oversaw Fast Furious (Eric Holder) was the FBI official who gave the ok to supply McVeigh and Nichols with their hundreds of pounds of fertilizer and nitrates

why do we believe anything or selective things our government tells us....

Money SRH


Conspiracies on small scale, never mind large scale can't occur due to common sense on Human nature and behaviour , and all the spying that goes on and listening, look at these
----------------------------------------------------------------------------

Note that peripheral figures in any conspiracy would be more likely to come forward because their limited role would not result in serious punishment-in fact, most likely no punishment at all because of a plea bargain in which they'd have to name higher-ups. And their inducement would be considerable financial rewards (books, TV movies based on their disclosures, etc.). And mere informants, who wouldn't be exposed to any legally adverse consequences, would only have financial rewards for coming forward.
---------------------------------------------------------------------------------------

it is not possible to keep secrets

In his book, Loving God, former presidential assistant Charles Colson, in writing about Watergate, said, "With the most powerful office in the world at stake, a small band of hand-picked loyalists [of President Richard Nixon] ... could not hold a conspiracy together for more than two weeks.”
--------------------------------------------------------------------------------


another point, it is amazing, that no other country intelligence gathered any intelligence about a 9/11 conspiracy, Russia and China would have had a field day with any conspiracy that USA had killed its own citizens. All conversations are monitored, other countries listen, the UK is one of the best at tracking and listening and you dont think MI5,MI6 CHQ would have picked up something, then you say UK was in on it as well.

---------------------------------------------------------------------------------

The report to the European Parliament of 2001 states: "If UKUSA states operate listening stations in the relevant regions of the earth, in principle they can intercept all telephone, fax and data traffic


the capability to listen in on every phone call, e-mail, fax and text .
---------------------------------------------------------------

 The entire English-speaking world is covered by a massive surveillance system which sifts through the mind-bogglingly large movements of data and communications every day.

---------------------------------------------------------------------

The largest computers in the world, stationed at the headquarters of inter-connected agencies such as the NSA, GCHQ (in the UK), DSD (in Australia, CSE (in Canada) and the GCSB (in New Zealand), listen in to just about everything. Their remit: anti-terrorism, external and internal threats, and sometimes they operate to counter threats to the economies of these countries

----------------------------------------------------------------------------

I would also presume Russia and China had a credible capability .

The 13 experts of the NIST Investigation would if there had been a conspiracy produced a fraudulant report


Apparently, then, such distinguished Americans as these experts got together in some smoky back room and all of them agreed, for some ungodly reason, to do the most dishonourable deed imaginable-give organized crime, the CIA, the military-industrial complex, or whoever was behind the 9/11, a free pass in the murder of citizens of United States.



And in the process, not only risk destroying everything they had worked for-their reputation and legacy to their families-but expose themselves to prosecution for the crime of accessory after the fact to murder. Ask yourself this: would any of these investigators, for instance, risk being remembered as an accessory after the fact to the murder of this nation's citizens, one who disgraced himself his country.




The mere asking of the question demonstrates the absurdity of the thought.


Indeed, why would any of the members of the NIST and their staff stake their good reputation on a report they prepared which they knew to be fraudulent?

BMA, the US government has been at war for 200+ years. This country owned slaves for 400+ years, has the highest incarceration rate in the world, is in the business of pharmaceuticals, the CIA was caught selling crack, US troops are guarding poppy fields in Afghanistan, the US military drops bombs on civilian targets, the US government experimented with chemical weapons on it own soldiers, the bush administration made billions on government contracts, lied about WMD's to go to war and sent US soldiers to die for colonialism, money, oil, lithium, minerals, industrialism, drugs, and yet you still believe the government isn't capable of killing it's own citizens for power and money?

actually when our currency was backed by gold or silver, we were not at war. with a flexible fiat currency we can be at war all the time. Fed created in 1913. since then, 100 years of war to equate with the 100 years of fiat currency

the only thing you are missing is why we went to war in afghanistan & iraq and why they want war in syria, libya, and iran

its because those nations do not, or did not have a privately owned central bank...or they were going to trade their oil for gold or euros instead of US dollars

understand that and you understand why we are in the middle east and why so many of our brothers have gone and died

BMA - the Dems and Republicans in Congress work for the Fed as does the President. The Fed works for its owners. Who are its owners? no one knows for sure

But as former Nixon aide G. Gordon Liddy once said (and he should know!), the problem with government conspiracies is that bureaucrats are incompetent and people can’t keep their mouths shut

Complex conspiracies are difficult to pull off, and so many people want their quarter hour of fame that even the Men in Black couldn’t squelch the squealers from spilling the beans. So there’s a good chance that the more elaborate a conspiracy theory is, and the more people that would need to be involved, the less likely it is true.

The USA is the greatest country in the World.

Thank the USA for the freedom and democracy of the Western World.

Thank USA military might for the protection of Western freedom and values.

The USA saved the West from annihilation in two world wars.

God Bless America.

God Bless NATO.
