The AE911Truth Petition
To the Members of the House of Representatives and of the Senate of the United States of America,
PLEASE TAKE NOTICE THAT:
On Behalf of the People of the United States of America, the undersigned Architects and Engineers for 9/11 Truth and affiliates hereby petition for, and demand, a truly independent investigation with subpoena power in order to uncover the full truth surrounding the events of 9/11/01 – specifically the collapses of the World Trade Center Towers and Building 7. We believe there is sufficient doubt about the official story and therefore the 9/11 investigation must be re-opened and must include a full inquiry into the possible use of explosives that might have been the actual cause of the destruction of the World Trade Center Twin Towers and Building 7.

The tragedy of 9/11 has been used to drive our nation into war and circumscribe the personal freedoms of the American people. The conclusions of the government investigation do not account for all of the phenomena reported, so the current explanation is incomplete and the investigation must be reopened.

I am a freelance Graphic Artist working in print and web media, with a passion for drawing & painting, printmaking, photography, and more recently, reclaimed artwork using recycled print materials that would normally find their way into a landfill. I find this medium is a great way to encourage recycling, while minimizing my own effects on the environment.
On September 11th I was working at a technical call center supporting a legal research provider. Some of our employees were on the phones with clients who witnessed a plane hit the world trade center before terminating their calls. Every one around me had news reports on their monitors, some of them describing explosions at the WTC. Suddenly, access to major news media websites was disrupted. Page Cannot Be Displayed was the only message on news outlets for several minutes. When the websites returned, all the reports of explosions were gone. I got off work just in time that day to witness WTC7 collapse on the news. Since then, I have researched anything and everything I could find about reports of explosions that day. The videos of the towers collapsing definitively show sequential explosions and flashes up the corners of the towers in multiple videos, from various angles. These flashes cannot be reflections when seen from several angles on the island. These sequential bursts are accompanied by sequential explosions, as recorded on video and reported by first responders. The official report doesn't address it, and I feel deliberately oppressed this information. Now almost a decade later, there are still no answers about the explosions, the molten metal in each footprint, or the mis-handling of the investigation. With this considered along with the revelation of nano-thermite materials found in the WTC dust, I feel only an independent peer-reviewed investigation will ever put any of this to rest.

I witnessed on live television the smoke of the first of the Twin Towers to be struck, and then witnessed the striking of the second tower. In my head were the words, ''They went and did it.'' They being nefarious, behind the scenes, persons and clandestine groups/societies that I have followed the histories and activities of for many years. The ''free fall'' collapsing of the towers and the subsequent likewise collapse of Building Seven were obvious controlled demolitions. I have taken ''heat'' for being one of those ''conspiracy guys'' for years. I have been taunted many times with the mantra, ''Oh - you think our government did it.'' I have never accused our government, however, I am disappointed in their lack of forensic investigations and conclusions. This attack was a huge false flag that, thank God, did not topple our republic.

The last 5 years I have been designing foundations and structural steel supports and platforms for the oil and gas industry.
I was in college taking tests when the event occurred. My most salient memory is getting a parking ticket at my apartment due to 'street cleaning' (in september ... really?). I guess I was too distracted to take notice that day. It wasn't until mid 2018 that I became aware of building 7 collapse. The media has spun its spell very well, as NO ONE I have talked to about building 7 was aware it even collapsed or the reporting from Donald Rumsfeld report the day prior! I always suspected that a typical fire should not have been able to bring the towers down when a high speed plane impact only made a hole, but accepted the narrative that BOTH towers had similar floor connection failures which precipitated a cascading collapse. I no longer accept that theory after finding out that the investigation was mandated to only the events leading up to the collapse. After learning of building 7 and the reporting surrounding it, it is clear we need a thorough unbiased investigation into this even to give the country closure and hold any guilty parties accountable. We need to restore law and order!

I became familiar with steel structures as a draftsman for Kerr McGee designing offshore drilling rigs from 1979-82. After spending 3.5 years to earn a BS mechanical engineering degree at the University of Oklahoma in 1985, the oil industry was in a deep recession. The next couple of years were spent developing and designing robots and industrial manipulator arms. 1988-90 were interesting years at Rockwell Rocketdyne developing rocket engine systems for Star Wars. Since 1990 the technical challenge of electrical submersible pumping systems for the oil industry has been my profession. Currently as Principal Engineer at Baker Hughes International I mentor young engineers and serve as a technical adviser for a wide range of system and mechanical challenges for the BHI Centrilift products.
The case made in these documentaries is virtually 100% against the official record and points to some very disturbing likely possibilities. A proper investigation is needed before some very dark elements in our government are able to deliver us all the way down the road to serfdom.

From the day it happened, the WTC Building 7 collapse looked suspicious. Seeing the collapse for the first time seemed surreal and caused me to wonder how this building could possibly collapse and come straight down. There didn't seem to be sufficient damage to WTC Building 7 for it to collapse especially when considering that the entire building came down virtually within its own foot print. Therefore, if this was a planned demolition, then there is suspicion cast on the events of 9/11.

When I was a child of 12 even I was shocked and strongly confused that the buildings fell and that they did so in a fashion that resembles a C.D., exactly. When 7 fell my ultimatum was if unexplained, it was a C.D.. When I came across thermite and saw a video of it burning through an iron engine block within a second, it became clear how it could be done.

There is no way that building 7 could have collapsed due the the light fire damage it sustained from the other buildings, the eye witness testimony also points to this fact. All building collapses defy the laws of physics - energy is needed to pulverize the concrete, thus if explosives were not used then you would expect to see the buildings as they fell. The buildings also collapsed through the path of greatest resistance.

I have been an engineer for 26 years and have worked in South Africa and the USA. For the last 13 years I have lived in Detroit, and for most of this time I have been involved in automotive suspension design, catering to the OEM automotive market. My work has involved design analysis, product development, problem solving, project management and customer liaison.
It has become clear to me that the official story, that describes the reasons for the 911 WTC building collapses, is fundamentally flawed. There are hundreds of gaping anomalies and unanswered questions. The most obvious question is how Building 7 collapsed. The much delayed explanation appears fraudulent. Similar very substantial issues remain with the Building 1 and 2 official reports. The most plausible explanation appears to be that of controlled demolition - for the destruction all three buildings. It is important that the truth is known - of what really happened. Most of all, this is owed to the families of the victims, who had to fight long and hard for the first official report - which was a dismal failure. A new investigation is needed imminently.

The official account of 9/11 is not credible. Steel does not melt in office furniture fires and airplane turbine engines don't vaporize. It would be like your BBQ grill melting if you put wood chips in it.

My knowledge of engineering principles tells me that the goverment's explanation for the collapse of WTC 1, 2 and 7 is inconsistent with the observed speed and symmetry of the collapse of those buildings. If the government's explanation was valid it should have significant implications for building codes and the way we design and build high rise buildings. Yet virtually no changes have occurred in structural engineering codes since 9/11/01. I am upset that an NFPA 921 investigation was never done on these three buildings, nor a proper forensic investigation of the structural components of these three buildings.

Being that 9/11 is one of the most formative events of our lifetimes (socially, legally, geopolitically, etc.), it seems imperative that the truth of the events be known. The official story has entirely too many holes, inaccuracies, and contradictions, making the need to reevaluate it self-evident. The evidence on this website, and collected in many other locations across the globe, bears the mark of truth and deserves public recognition.

I graduated with a BS in mechanical engineering from BYU. I have studied heat transfer, kinematics, static and dynamic structures, as well as structures of materials. I currently work as a design engineer at a top aerospace engine manufacturer specializing in CAE tool development including finite element analysis.
I have an analytical as well as gut-level feel for how structures should behave under loads. WTC1 and 2 buildings were designed with redundant load bearing members for the explicit purpose to be able to absorb impacts from airliners as this was one of many design considerations at the time. The buildings should each have remained intact for longer than was witnessed below their impact zones - if a dynamic failure were to occure with upper levels impacting the lower levels, each structural framework in each floor below would offer some resistance, significantly slowing the speed of collapse compared against a free-falling body. The rapid speed of descent as seen in footage indicates no resistance in the members meaning something more was going on in the levels below the impact and fires. The clouds of pulvarized concrete billowing out during the collapse also raises flags. The amount of the dust generated is extreme and its pyroclastic behaivor indicates it had been superheated which is not readily explained in a simple collapse scenario. When I first saw the collapse of the towers on September 11, I was just out of high school and had basically no engineering background. In my journal that day I noted how it looked like the buildings were being demolished like the old casinos in Las Vegas. Concerning the complete casino-style collapse of Building 7, this was simply overt and is beyond suspicious. I hadn't seen the videos of Building 7 until several years later, but anyone who watches these videos is hard-pressed to explain the complete symmetrical collapse of the building with the top descending at near free-fall speed as a result of fires only.

My wife and I were horrified as we watched the live news reports of that day, particularly when we saw the second plane hit Tower 2. Over the next few days I continued to watch video replays of Twin Towers 1 & 2 and could not comprehend how both towers could collapse as they did. As a Structural Engineer, it made no sense to me how the structural framing system below the impact level did not continue to support the structure. It was only in the last few weeks, as I researched and found this site, that I found out that building 7 had also collapsed. I agree that it has the classic signs of a controlled demolition. Thanks to all of you who created this site. I am proud to be part of the cause to get congress to conduct a full investigation.

In the case of Building 7 I'm very confident that there was a true and very well studied implosion, demolishing the building so that it collapses straight down into its own footprint (the total area at the base of the building). This feat requires such skill that only few and very experienced demolition experts in the world will attempt it. Among other evidences, the way and time of the building collapse indicates a previous study of the building structure. The motion during the fall was almost vertical and therefore cannot be by hazard, or even caused by a fire, because all supports must be cutted at the same time, or in a specific way that the columns at the center of the building are cutted before the other columns so that the building's sides fall inward.

I believe that we have not been told the whole truth about the skyscrappers destruction. Evidence collected on that day clearly point toward some kind of controlled demolition in addition to the plane crashes.The explanations that have been given by governement officials do not explain what can be observed on the video fottage collected on 9/11. Somethings have not been told, information is being kept from the public.

It is my view that a truly independent investigation about the episodes concerning the collapses of the WTC buildings is required. The official 9/11 Commission Report does not provide a satisfactory analysis: it has omitted evidences and its argumentation scheme has strong value assumptions and ambiguities that make its conclusion not acceptable from my critical thinking perspective.

I have been a consulting engineer for 20 years. My main area of expertise is in land development and infrastructure design. I have had some limited exposure to structural design of bridges and small structures.
As an engineer it is hard to refute the evidence that this appears to have been a controlled demolition. It seems to me that there were just too many things that had to occur at exactly the same time for the collapse to have occurred solely from a plane hit.

I don't believe that the three buildings came down as a result of fires. They were steel buildings, and, from what I have read, jet fuel does not burn hot enough to burn steel. Also, the free-fall of the buildings appear to be that of a controlled demolition, not due to fires. The buildings came down so fast, and without stopping at each floor level, which doesn't seem possible, unless the columns were pulled out, as would have been done to start a controlled demolition.

It wasn't until 2009 that I came across issues related to Tower 7. Prior to that, I barely even recalled that there was a third structure that collapsed that day. I have not been involved in a tower demolition yet, however I've built enough concrete, steel and composite high-rise buildings, from planning and design to ground-breaking through hand-over, to understand and appreciate methods needed to bring a building down in a matter of seconds. I am mostly interested in finding out how and when the towers were prepared for such a demolition as that activity alone is 1.) is extensive and time-consuming, and 2.) on its own, enough to substantially weaken the buildings and render them unfit for occupancy. I am convinced that the official story is indeed untrue and an independent investigation is warranted and appropriate.

I am an engineering professional who works for a large software company. I studied engineering at Brigham Young University and first became involved officially with the 9/11 truth movement in 2004.
I believe the evidence is overwhelming that the destruction of the Twin Towers and WTC 7 did not occur as the 'official' narrative suggests. I call on the American people to demand answers!

I`m a 25 year old engineer working for the Canadian Federal Government in Motor Vehicle Regulations. I have obtained my bachelor`s degree at Ottawa University in 2009. I have designed a steel structural chassis for an amphibious vehicle which was fully analyzed, designed, and documented with drawings for manufacturing of the parts.
The core column for the twin towers was a combination of massive steel rods and cement and were amongst the strongest steel columns in the world. A fire in open air could potentially have weakened the steel in the column at a single point on the 100-sotry buildings, although this is highly unlikely given the steel melting point is much higher than a fire by kerosene in open air. But the cement in the column would still have sustained the building upwards. The problem is the column could have flexed and broken at that point, but the building would have fallen sideways. The floors below were designed to sustain 10 times the weight of all floors above at full capacity. The only way the column could have collapsed upon itself is if it was brought to malleability from top to bottom simultaneously, including the skeleton structural steel rods. But this was not the case. And even if it was, all the floors, walls, and other structural components would have created resistance and the collapse would have been slow. What the evidence shows is that they collapse at free fall speed minus air resistance. This is only achievable in a controlled demolition which removes the matter with explosives before the above floors reach the ones below. This is not to mention building 7. You don`t need expertise to break that one down.
