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.

I am a Structural Engineer with over 43 years of experience in bridge design, construction engineering, research and development, and forensic engineering. I have been project designer for the San Francisco Oakland Bay Bridge (Skyway, East Tie In, and Oakland Touch Down Detour) and the Benicia Martinez Bridge (CA) as well as numerous other bridges valued at over $200M. I am currently working on the planned demolition of the old San Francisco Oakland Bay Bridge (east cantilever truss) and the new Gerald Desmond Bridge at Long Beach Harbor in California. - - - - I have provided construction engineering services for several major bridges including precast and cast-in-place, prestressed concrete box girder bridges constructed by segmental methods, a major concrete arch structure. a cable suspension bridge, and steel truss bridges. - - - - I was Principal Investigator for the Applied Technology Council project ATC-32 for the development of seismic design recommendations for California bridges as well as serving on several other ATC projects. I have taught several courses on the seismic design and retrofitting of bridges for FHWA, Caltrans, UC Berkeley, etc., and was recipient of the ATC Award of Excellence for Extraordinary Achievement in Seismic Design and Retrofitting of Bridges. - - - - I have conducted forensic engineering studies and served as expert witness for the premature collapse during demolition of the Chile Bar Bridge in California, and participated in the forensic investigation of a steel eye-bar failure on the existing San Francisco Oakland Bay Bridge.
It is clear from the additional evidence uncovered by A&E for 911truth that the people have not been told the whole truth about the building collapses during the events of 9/11/01. New evidence may point to sinister participation by elements within our own government. Because of the impact of these events on our current political and financial situation and on the future of our republic, it is imperative that the investigation be reopened to either lay these suspicions to rest or to expose any wrong doing. This will be necessary before we can heal as a nation.

My name is James Alexander Moore, I grew up in Pittsburgh, PA and worked in construction for two years before going to Wittenberg University for Political Science. I have never felt contempt with the official 9/11 Commission and would like to see an independent investigation especially into the WTC7 collapse. I have always taken the events of September 11th very seriously, with flight 93 crashing only an hour drive from my home. I demand to see a proper investigation of all the events that took place that day for the families of the victims and for the people of the world that have dealt with the consequences of our reaction to that day.
The manner in which Tower seven collapsed was unlike Towers 1 and 2 in that it seemed to completely cave in on itself. I did not see one side fail before another. Therefore if the fires on the one side of the Tower were responsible for the collapse it would have fallen in that direction. Towers 1 and 2 both collapsed from the point of impact taking out the stories below it in a domino effect. I witnessed nothing like that with building 7, it was identical to a controlled demolition. From the evidence I have been presented I feel obligated to sign this petition to have a true legitimate investigation into the collapse of the World Trade Towers.

I have working in the oil industry for 21 years. I am currently employed with Noble Drilling Services, a major offshore drilling contractor, as director of engineering for research and development.
I was shocked by 9/11. As an optimist I gave the official story the benefit of the doubt. I am not a believer in conspiracies but your documentary gave me pause. If there is a hint of impropriety in the official story, then it is likely to only be the tip of the iceberg. I hope to god it is wrong, but in my profession, hope doesn't cut it. I need to see evidence that makes sense. The NIST backtracking and weak arguments don't reassure me; as an engineer, I understand the issues raised. Also, in my industry, an objective third party review is always used. I would expect the same from our government.

I worked for Bausch and Lomb, Management & Technology Inc, and Eastman Kodak Company (both federal systems and commercial products). After retiring from Kodak I worked for a couple of small companies developing and making digital cameras. Then I started a new business with another engineer within Kodak making 3 dimensional images. I'm currently working on contract basis to help inventors learn how to patent their own inventions, help them make prototypes, and do patent searches. I am also working with another company to sell patents for licensing opportunities.
I was unaware of Bldg 7 for several years until my daughter told me about it. I had heard it was a controlled demolition due to the damage inside from fires started from the twin towers. However, I have grown increasingly skeptical about the planes causing the collapse of the twin towers because I could not see that damage causing the collapse of the floors below it. The outside materials peeling away from the structural steel were also unexplained. I would have thought the buildings would have collapsed more laterally in the direction of the impact points. I saved the Washington Journal interview with Mr. Gage to show my daughter and have decided to sign the petition.

I got interested because of the polls showing an international opinion of over 50% believing it wasn't terrorists. When I saw this I felt the government had a responsibility to prove the case. When they didn't and wouldn't, I did an investigation of my own. I used my ability to trouble shoot situations where the investigator is even presented with lies, which is often the case, to conclude the buildings did not come down from fire or the damage from planes. The Silvestein interview was the first bad data point concerning the situation. Then I found more than I needed to support my theory beyond any doubt.

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.

The pictures of the WTC buildings falling straight down at almost free-fall speed make it hard for me to believe two airplanes were the sole cause of failure. This is especially true of Building 7.

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.

Degree and Licenced by Instituto Superior Tecnico, in 1982. For more than 25 years I'v been responsible for hundreds of structural projects of bridges and buildings.

Also responsible for checking drawings and design calculations done by other engineers. Some of the projects can be seen at my firm home page.
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.

My software simulation background tells me that simulation results without knowing the inputs to the simulation are meaningless. That NIST is secretive about their methods casts grave doubts on their reported results.

My decisions are always based on logic, facts, and evidence. When you look at the MASSIVE amount of facts and evidence around 9/11, a reasonable, rational person can only come to one conclusion. It wasn't just the planes...

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.
