Footage that kills the conspiracy theories: Unseen 9/11 footage shows WTC Building 7 consumed by fire

The video shows up-close shots of the lower floors of World Trade Center Building 7, located just across the street from the Twin Towers, and focuses in on the exterior metal beams of Building 7 as they begin to buckle as they are overheated.

The buckling led to floors falling in on one another, causing the building to collapse.


http://www.dailymail...sumed-fire.html


The Collapse of the South Tower

As the fires continued to burn, occupants trapped in the upper floors of the South Tower provided information about conditions to 9-1-1 dispatchers. At 9:37 am, an occupant on the 105th floor of the South Tower reported that floors beneath him "in the 90-something floor" had collapsed. The New York City Police Department aviation unit also relayed information about the deteriorating condition of the buildings to police commanders.

Only 14 people escaped from the impact zone of the South Tower after it was hit (including Fuji Bank Executive Stanley Praimnath, who saw the plane coming at him), and only four from the floors above it. They escaped via Stairwell A, the only stairwell which had been left intact after the impact. Numerous police hotline operators who received calls from individuals inside the South Tower were not well informed of the situation as it rapidly unfolded in the South Tower.

Many operators told callers not to descend the tower on their own, even though it is now believed that Stairwell A was most likely passable at and above the point of impact. At 9:52 am, the NYPD aviation unit reported over the radio that "large pieces may be falling from the top of WTC 2. Large pieces are hanging up there".With the warnings, the NYPD issued orders for its officers to evacuate. During the emergency response, there was minimal communication between the NYPD and the New York City Fire Department (FDNY), and overwhelmed 9-1-1 dispatchers did not pass along information to FDNY commanders on-scene. At 9:59 am, the South Tower collapsed, 56 minutes after being struck.


The Collapse of the North Tower

After the South Tower collapsed, NYPD helicopters relayed information about the deteriorating conditions of the North Tower. At 10:20 am, the NYPD aviation unit reported that "the top of the tower might be leaning," and a minute later reported that the North Tower, "is buckling on the southwest corner and leaning to the south". At 10:28 am, the aviation unit reported that "the roof is going to come down very shortly." The North Tower collapsed at 10:28 am, after burning for 102 minutes.

After the South Tower collapsed, FDNY commanders issued orders for firefighters in the North Tower to evacuate. Due to radio communications problems, firefighters inside the towers did not hear the evacuation order from their supervisors on the scene, and most were unaware that the other tower had collapsed. 343 firefighters died in the Twin Towers, as a result of the collapse of the buildings. No one was able to escape from above the impact zone in the North Tower after it was hit, as all stairwells and elevator shafts on those floors were destroyed or blocked.

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

In other words, fire, not explosives nor thermite, was responsible for the collapse of the WTC buildings.

On the contrary, even the Association of Architects discredited Richard Gage.

ARCHITECT Magazine

The Magzine of the American Institute of Architects

All of Gage’s so-called evidence has been rebutted in peer-reviewed papers, by the Federal Emergency Management Agency, by the National Institute for Standards and Technology, by the American Society of Civil Engineers, by the 9/11 Commission Report, and, perhaps most memorably, by the 110-year-old engineering journal Popular Mechanics.

Now, let's take a look at Steven Jones because Steven Jones has been found guilty of lying about molten steel and thermite and he has been discredited by Brigham Young University.

Letter to the Editor
Refuting 9/11 Conspiracy Theory

April 09, 2006

Dear Editor,
After reading in the Daily Herald the presentations made by Professor Steven E. Jones (BYU Physics) to students at UVSC and BYU, I feel obligated to reply to his "Conspiracy Theory" relating to the terrorist attacks on the World Trade Center (9/11/01).

I have studied the summary of the report by FEMA, The American Society of Civil Engineers and several other professional engineering organizations. These experts have given in detail the effects on the Towers by the impact of the commercial aircraft. I have also read Professor Jones' (referred to) 42 page unpublished report. In my understanding of structural design and the properties of structural steel I find Professor Jones' thesis that planted explosives (rather than fire from the planes) caused the collapse of the Towers, very unreliable.

The structural design of the towers was unique in that the supporting steel structure consisted of closely spaced columns in the walls of all four sides. The resulting structure was similar to a tube. When the aircraft impacted the towers at speeds of about 500 plus mph, many steel columns were immediately severed and others rendered weak by the following fires. The fires critically damaged the floors systems. Structural steel will begin to lose strength when heated to temperatures above 1000 degrees Fahrenheit. Steel bridge girders are bent to conform to the curved roadway by spot heating flanges between 800 and 1000 degrees Fahrenheit. It is easy to comprehend the loss of carrying capacity of all the structural steel due to the raging fires fed by the jet's fuel as well as aircraft and building contents.

Before one (especially students) supports such a conspiracy theory, they should investigate all details of the theory. To me a practicing structural engineer of 57 continuous years (1941-1998), Professor Jones' presentations are very disturbing.

D. Allan Firmage
Professor Emeritus, Civil Engineering, BYU

Buildings were designed to withstand plane impacts.

Quote

A lead engineer who designed the World Trade Center Towers expressed shock that the towers collapsed after being hit by passenger jets.“I designed it for a 707 to hit it,” Lee Robertson, the project’s structural engineer said. The Boeing 707 has a fuel capacity of more than 23,000 gallons, comparable to the 767′s 23,980-gallon fuel capacity.

Another architect of the WTC, Aaron Swirski, lives in Israel and spoke to Jerusalem Post Radio after the attack: “It was designed around that eventuality to survive this kind of attack,” he said.

Hyman Brown, a University of Colorado civil engineering professor and the World Trade Center’s construction manager, watched in confusion as the towers came down. “It was over-designed to withstand almost anything including hurricanes, high winds, bombings and an airplane hitting it,” he said.

Eyewitness accounts of people at GZ who reported explosions before the tower collapses

Quote

"Shortly after 9 o'clock [...] [Albert Turi the Chief of Safety for the New York Fire Department] received word of the possibility of a secondary device, that is another bomb going off. He tried to get his men out as quickly as he could, but he said there was another explosion which took place, and then an hour after the first hit, the first crash that took place, he said there was another explosion that took place in one of the towers here, so obviously according to his theory he thinks that there were actually devices that were planted in the building.
One of the secondary devices he thinks that took place after the initial impact he thinks may have been on the plane that crashed into one of the towers. The second device, he thinks, he speculates, was probably planted in the building."
----------------------------------------------

We got down as far as the 74th floor [...] Then there was another explosion, so we left again by the stairwell.
Kim White, WTC 1 survivor, on 80th floor at time of impact
------------------------------------------
One eyewitness whose office is near the World Trade Center told AFP that he was standing among a crowd of people on Church Street, about two-and-a-half blocks from the South tower, when he saw "a number of brief light sources being emitted from inside the building between floors 10 and 15." He saw about six of these brief flashes, accompanied by "a crackling sound" before the tower collapsed. Each tower had six central support columns. [American Free Press]
http://www.americanf...bombs_expl.html
------------------------------------------
When the rescue team reached an area directly in front of Tower Two, Antonio said he'd take over the equipment cart Will had pushed from Building 5. [...] The team moved ahead. Scant minutes passed. Suddenly the hallway began to shudder as a terrible deafening roar swept over them. That's when Will saw the giant fireball explode in the street.
------------------------------------------
•Official: Battalion 3 to dispatch, we've just had another explosion.
•Official: Battalion 3 to dispatch, we've had additional explosion.
•Dispatcher: Received battalion command. Additional explosion.
•[...]
•Dispatcher: Battalion 5, be advised we're trying to contact Battalion 3 at this moment to report north tower just collapsed.
911 Tapes Tell Horror Of 9/11
------------------------------------------
The following is taken from an email Neil deGrasse Tyson sent to his family and friends on 12 September 2001. Neil witnessed the attacks on the twin towers from his apartment only six blocks from the World Trade Center.

"As more and more and more and more and more emergency vehicles descended on the World Trade Center, I hear a second explosion in WTC 2, then a loud, low-frequency rumble that precipitates the unthinkable -- a collapse of all the floors above the point of explosion. First the top surface, containing the helipad, tips sideways in full view. Then the upper floors fall straight down in a demolition-style implosion, taking all lower floors with it, even those below the point of the explosion."
"I decide it's time to get my daughter, who was taken by the parents of a friend of hers to a small office building, six blocks farther from the WTC than my apartment. As I dress for survival: boots, flashlight, wet towels, swimming goggles, bicycle helmet, gloves, I hear another explosion followed by a now all-too familiar rumble that signaled the collapse of WTC 1, the first of the two towers to have been hit. I saw the iconic antenna on this building descend straight down in an implosion twinning the first."

The Elevator Man's Tale

The Elevator Man's Tale
Featuring the unabridged transcript and audio.

Robert Jones
Age: 52
Hometown: Montgomery
Family: Two children
Occupation: Elevator mechanic for Ace Elevator in the World Trade Center
Was in the south tower when the first plane hit.


As I turned around to go back toward the core of the building in the lobby, the second plane hit, and that shook the building.

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.

And apparently from what I talked to with other mechanics, they saw the doors, the hatch doors blow off in the lobby level of 6 and 7 car.


http://www.thrnewmed...ember/jones.htm

Many things can sound like explosions, but not be produced by explosions, in an elevator shaft during an event like 9/11. One example from 2000, when an elevator missed its stop and hit the shaft ceiling:

Others [present] described the crash as sounding like a horrendous "boom."

People "thought it was a bomb," said Kim Dunlap, a receptionist on the 100th floor. It rocked the building. There's never a dull moment at the World Trade Center."


The report issued by Lamont-Doherty includes various graphs showing the seismic readings produced by the planes crashing into the two towers as well as the later collapse of both buildings. WhatReallyHappened.com chooses to display only one graph (Graph 1), which shows the readings over a 30-minute time span.On that graph, the 8- and 10-second collapses appear—misleadingly—as a pair of sudden spikes. Lamont-Doherty's 40-second plot of the same data (Graph 2) gives a much more detailed picture: The seismic waves—blue for the South Tower, red for the North Tower—start small and then escalate as the buildings rumble to the ground. Translation: no bombs.

Fire, Not Extra Explosives, Doomed Buildings, Expert Says

By John Fleck
Journal Staff Writer


A New Mexico explosives expert says he now believes there were no explosives in the World Trade Center towers, contrary to comments he made the day of the Sept. 11 terrorist attack.
"Certainly the fire is what caused the building to fail," said Van Romero, a vice president at the New Mexico Institute of Mining and Technology. The day of the attack, Romero told the Journal the towers' collapse, as seen in news videotapes, looked as though it had been triggered by carefully placed explosives.

Subsequent conversations with structural engineers and more detailed looks at the tape have led Romero to a different conclusion. Romero supports other experts, who have said the intense heat of the jet fuel fires weakened the skyscrapers' steel structural beams to the point that they gave way under the weight of the floors above. That set off a chain reaction, as upper floors pancaked onto lower ones.

“I saw a couple of elevators in free fall; you could hear them whizzing down and as they crashed, there was this huge explosion, like a fireball exploding out of the bank of elevators,” Kravette said. “People were engulfed in flames.”

Heres some facts and evidence....

Quote

Why was there Molten Metal Under Ground Zero for Months after 9/11?


Molten metal flowed underneath ground zero for months after the Twin Towers collapsed:

New York firefighters recalled in a documentary film, "heat so intense they encountered rivers of molten steel."

A NY firefighter described molten steel flowing at ground zero, and said it was like a "foundry" or like "lava".

A public health advisor who arrived at Ground Zero on September 12, said that "feeling the heat" and "seeing the molten steel" there reminded him of a volcano.

An employee of New Jersey's Task Force One Urban Search and Rescue witnessed "Fires burn[ing and molten steel flow[ing] in the pile of ruins still settling beneath her feet."

The head of a team of scientists studying the potential health effects of 9/11, reported, "Fires are still actively burning and the smoke is very intense. In some pockets now being uncovered, they are finding molten steel."

According to a worker involved with the organizing of demolition, excavation and debris removal operations at ground zero, "Underground it was still so hot that molten metal dripped down the sides of the wall from Building 6."

An expert stated about World Trade Center building 7, "A combination of an uncontrolled fire and the structural damage might have been able to bring the building down, some engineers said. But that would not explain steel members in the debris pile that appear to have been PARTLY EVAPORATED in extraordinarily high temperatures" (pay-per-view). Note that evaporation means conversion from a liquid to a gas; so the steel beams in building 7 were subjected to temperatures high enough to melt and evaporate them.

A rescue worker "crawled through an opening and down crumpled stairwells to the subway five levels below ground. He remembers seeing in the darkness a distant, pinkish glow–molten metal dripping from a beam"

A reporter with rare access to the debris at ground zero "descended deep below street level to areas where underground fires still burned and steel flowed in molten streams."

A structural engineer who worked for the Trade Center's original designer saw "streams of molten metal that leaked from the hot cores and flowed down broken walls inside the foundation hole." (pages 31-32)

An engineer stated in the September 3, 2002 issue of The Structural Engineer, "They showed us many fascinating slides ranging from molten metal, which was still red hot weeks after the event."

An Occupational Safety and Health Administration Officer at the Trade Center reported a fire truck 10 feet below the ground that was still burning two weeks after the Tower collapsed, "its metal so hot that it looked like a vat of molten steel."

A witness said “In the first few weeks, sometimes when a worker would pull a steel beam from the wreckage, the end of the beam would be dripping molten steel”

The structural engineer responsible for the design of the WTC, described fires still burning and molten steel still running 21 days after the attacks (page 3).

According to a member of New York Air National Guard's 109th Air Wing, who was at Ground Zero from September 22 to October 6, "One fireman told us that there was still molten steel at the heart of the towers' remains. Firemen sprayed water to cool the debris down but the heat remained intense enough at the surface to melt their boots."

A retired professor of physics and atmospheric science said "in mid-October when they would pull out a steel beam, the lower part would be glowing dull red, which indicates a temperature on the order of 500 to 600 °C. And we know that people were turning over pieces of concrete in December that would flash into fire--which requires about 300 °C. So the surface of the pile cooled rather rapidly, but the bulk of the pile stayed hot all the way to December."

A fireman stated that there were "oven" like conditions at the trade centers six weeks after 9/11.

Firemen and hazardous materials experts also stated that, six weeks after 9/11, "There are pieces of steel being pulled out [from as far as six stories underground] that are still cherry red" and "the blaze is so 'far beyond a normal fire' that it is nearly impossible to draw conclusions about it based on other fires." (pay-per-view)

A NY Department of Sanitation spokeswoman said "for about two and a half months after the attacks, in addition to its regular duties, NYDS played a major role in debris removal - everything from molten steel beams to human remains...."

New York mayor Rudy Giuliani said "They were standing on top of a cauldron. They were standing on top of fires 2,000 degrees that raged for a hundred days."

As late as five months after the attacks, in February 2002, firefighter Joe O'Toole saw a steel beam being lifted from deep underground at Ground Zero, which, he says, "was dripping from the molten steel."

Indeed, the trade center fire was "the longest-burning structural fire in history", even though it rained heavily on September 14, 2001 and again on September 21, 2001, and the fires were sprayed with high tech fire-retardands, and "firetrucks [sprayed] a nearly constant jet of water on" ground zero."

Indeed, "You couldn't even begin to imagine how much water was pumped in there," said Tom Manley of the Uniformed Firefighters Association, the largest fire department union. "It was like you were creating a giant lake."

No Molten Steel at Ground Zero

9/11 shill Steven E. Jones fooled the truth movement into believing the false and inadequate thermite and molten metal theories. Jones’ molten metal evidence has been shown to be fabricated.

What Do the Experts Say?

What does the evidence show about the Solomon Brothers Building in Manhattan? Numerous structural engineers – the people who know the most about office building vulnerabilities and accidents – say that the official explanation of why building 7 at the World Trade Center collapsed on 9/11 is “impossible”, “defies common logic” and “violates the law of physics”:

Two professors of structural engineering at a prestigious Swiss university (Dr. Joerg Schneider and Dr. Hugo Bachmann) said that, on 9/11, World Trade Center 7 was brought down by controlled demolition (translation here)

John D. Pryor, with more than 30 years experience: The collapse of WTC7 looks like it may have been the result of a controlled demolition. This should have been looked into as part of the original investigation

Robert F. Marceau, with over 30 years of structural engineering experience: From videos of the collapse of building 7, the penthouse drops first prior to the collapse, and it can be noted that windows, in a vertical line, near the location of first interior column line are blown out, and reveal smoke from those explosions. This occurs in a vertical line in symmetrical fashion an equal distance in toward the center of the building from each end. When compared to controlled demolitions, one can see the similarities

Kamal S. Obeid, structural engineer, with a masters degree in Engineering from UC Berkeley and 30 years of engineering experience, says: Photos of the steel, evidence about how the buildings collapsed, the unexplainable collapse of WTC 7, evidence of thermite in the debris as well as several other red flags, are quite troubling indications of well planned and controlled demolition

Steven L. Faseler, structural engineer with over 20 years of experience in the design and construction industry: World Trade Center 7 appears to be a controlled demolition. Buildings do not suddenly fall straight down by accident

Alfred Lee Lopez, with 48 years of experience in all types of buildings: I agree the fire did not cause the collapse of the three buildings [please ignore any reference in this essay to the Twin Towers.  This essay focuses solely on Building 7]. The most realistic cause of the collapse is that the buildings were imploded.

Ronald H. Brookman, structural engineer, with a masters degree in Engineering from UC Davis, writes: Why would all 47 stories of WTC 7 fall straight down to the ground in about seven seconds the same day [i.e. on September 11th]? It was not struck by any aircraft or engulfed in any fire. An independent investigation is justified for all three collapses including the surviving steel samples and the composition of the dust.

Graham John Inman points out: WTC 7 Building could not have collapsed as a result of internal fire and external debris. NO plane hit this building. This is the only case of a steel frame building collapsing through fire in the world. The fire on this building was small & localized therefore what is the cause?

Paul W. Mason notes: In my view, the chances of the three buildings collapsing symmetrically into their own footprint, at freefall speed, by any other means than by controlled demolition, are so remote that there is no other plausible explanation

David Scott says: Near-freefall collapse violates laws of physics. Fire induced collapse is not consistent with observed collapse mode . . . .

Nathan Lomba states: How did the structures collapse in near symmetrical fashion when the apparent precipitating causes were asymmetrical loading? The collapses defies common logic from an elementary structural engineering perspective.


***
Heat transmission (diffusion) through the steel members would have been irregular owing to differing sizes of the individual members; and, the temperature in the members would have dropped off precipitously the further away the steel was from the flames—just as the handle on a frying pan doesn’t get hot at the same rate as the pan on the burner of the stove. These factors would have resulted in the structural framing furthest from the flames remaining intact and possessing its full structural integrity, i.e., strength and stiffness.

Structural steel is highly ductile, when subjected to compression and bending it buckles and bends long before reaching its tensile or shear capacity. Under the given assumptions, “if” the structure in the vicinity … started to weaken, the superstructure above would begin to lean in the direction of the burning side. The opposite, intact, side of the building would resist toppling until the ultimate capacity of the structure was reached, at which point, a weak-link failure would undoubtedly occur. Nevertheless, the ultimate failure mode would have been a toppling of the upper floors to one side—much like the topping of a tall redwood tree—not a concentric, vertical collapse.

For this reason alone, I rejected the official explanation for the collapse ….


Edward E. Knesl writes: We design and analyze buildings for the overturning stability to resist the lateral loads with the combination of the gravity loads. Any tall structure failure mode would be a fall over to its side. It is impossible that heavy steel columns could collapse at the fraction of the second within each story and subsequently at each floor below.We do not know the phenomenon of the high rise building to disintegrate internally faster than the free fall of the debris coming down from the top.


The engineering science and the law of physics simply doesn’t know such possibility. Only very sophisticated controlled demolition can achieve such result, eliminating the natural dampening effect of the structural framing huge mass that should normally stop the partial collapse. The pancake theory is a fallacy, telling us that more and more energy would be generated to accelerate the collapse. Where would such energy would be coming from?

Antonio Artha with 15+ years of experience in building design: Fire and impact were insignificant in all three buildings [Again, please ignore any reference to the Twin Towers ... this essay focuses solely on WTC7]. Impossible for the three to collapse at free-fall speed. Laws of physics were not suspended on 9/11, unless proven otherwise.

Steven Francis Dusterwald: The symmetrical “collapse” due to asymmetrical damage is at odds with the principles of structural mechanics.

John S. Lovrovich: It is virtually impossible for WTC building 7 to collapse as it did with the influence of sporadic fires. This collapse HAD to be planned.

James Milton Bruner, Major, U.S. Air Force, instructor and assistant professor in the Deptartment of Engineering Mechanics & Materials, USAF Academy, and a technical writer and editor, Lawrence Livermore National Laboratory

Christopher Michael Bradbury: It is very suspicious that fire brought down Building 7 yet the Madrid hotel fire was still standing after 24 hours of fire. This is very suspicious to me because I design buildings for a living.


There is no such thing as magic, just magicians and fools.

Eyewitness accounts of people at GZ who reported explosions before the tower collapses

Let's take another look.

Quote

Testimony of those who heard such sounds but later attributed those sounds other than to explosives. Since it seems that you have forgotten, do a review here.

Explosions

"When we got to about 50 ft from the South Tower, we heard the most eerie sound that you would ever hear. A high-pitched noise and a popping noise made everyone stop. We all looked up. At the point, it all let go.The way I see it, it had to be the rivets. The building let go, there was an explosion and the whole top leaned toward us and started coming down."

He also says he thinks the rivets caused the building to fall and not bombs. Interestingly, the NIST said most of the failures were at the bolts and connections.

Louie Cacchioli, 51, is a firefighter assigned to Engine 47 in Harlem

Originally, on September 12, 2001, People Magazine ran a few short paragraphs about the 20-year veteran New York fireman hearing what sounded like bombs exploding in the north tower.

Short and sweet, that was it. A few short words about bombs exploding, but words that were repeated over and over again in story after story by writers and broadcasters who never even bothered to talk to him in the first place.

Furthermore, Cacchioli was upset that People Magazine misquoted him, saying "there were bombs" in the building when all he said was he heard "what sounded like bombs" without having definitive proof bombs were actually detonated.

Jay Swithers

An ambulance pulled up which was very clean, S0 I assumed that the vehicle had not been in the what I thought was an explosion at the time, but was the first collapse.

Dominick Derubbio

t was weird how it started to come down. It looked like it was a timed explosion, but I guess it was just the floors starting to pancake one on top of the other.


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

FDNY Batallion Chief Brian Dixon

I looked up and you could actually see everything blew out on the one floor. I thought, geez, this looks like an explosion up there, it blew out. Then I guess in some sense of time we looked at it and realized, no, actually it just collapsed. That ís what blew out the windows, not that there was an explosion there but that windows blew out.


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

Craig Carlsen said that he and other firefighters “heard explosions coming from . . . the south tower

...there were about ten explosions. At the time I didn't realize what it was. We realized later after talking and finding out that it was the floors collapsing to where the plane had hit.

So once again, just because someone heard the sound of explosions, is not evidence that bombs were involved.
And just because someone heard...
  • Rivets popping.
  • Floors Collapsing.
  • An explosion that blew out the floors which wasn't an explosions.
Nothing there indicating the use of explosives. There is no video of bomb explosions and no audio of bomb explosions and no evidence of bombs within the rubble of the WTC buildings and no seismic data of bomb explosions.

Verdict!! No bombs.

Nothing about Richard Gage here...lol

Let's take another look because no evidence of explosives nor thermite were ever found..

Quote

ARCHITECT Magazine
The Magzine of the American Institute of Architects

All of Gage’s so-called evidence has been rebutted in peer-reviewed papers, by the Federal Emergency Management Agency, by the National Institute for Standards and Technology, by the American Society of Civil Engineers, by the 9/11 Commission Report, and, perhaps most memorably, by the 110-year-old engineering journal Popular Mechanics.

Aside from Gage, though, there was not a single other architect in the room, much less an official from AIA, or even another member. The 80-strong crowd was made up largely of members of the local 9/11 Truth movement and other political activists.

In other words, Richard Gage has no real credibility within the Association of Architects, which represents thousands of members.
