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.

It never looked right to me, how the twin towers came down. I remember talking about it with co-workers at the time and the explanation was that the structural columns were hollow. Now I understand that the twin towers were in reality a very sturdy steel structure.

I am a chemical and environmental engineer and I attended the Indian Institute of Technology in New Delhi, a school that is highly recognized all over the world. I have designed industrial structures as part of chemical engineering, and have done engineering consulting for many years.
Jet fuel's capability is to create instant heat that can be immediately converted to mechanical energy. It does not have staying power as opposed to heavier organics like tar that hang around and help things burn. Jet fuel can help start a fire but it cannot be the the fuel that continues to burn something for a long time. So the world trade centers did not have jet fuel burning in them; it was merely office fires after the initial explosion. There was nothing capable of heating giant massive thick beams throughout the length of the towers or at any single point to cause the observed collapses. Only a controlled demolition can do what was seen and what was heard as well - multiple explosions, way past the jet strikes.

I am not qualified to comment on the particulars of explosive demolition; however, the laws of physics strongly suggest that there is some other mechanism at work in the dramatic collapse of the twin towers. Certainly any structure capable of withstanding the extreme forces inherent in a stable structure of that size would offer some resistance to a collapse. I would expect that an asymmetrically distributed failure, the kind of failure implied by the nature of the impact and resulting fire, would provide asymmetrical resistance that would in turn create a pivot-shearing failure that would result in the lower structure remaining largely intact while the upper structure rotated and collapsed outward in the direction of the least support. Even if the building happened to collapse evenly, it is highly unlikely that the supporting structure would offer no resistance to the collapsing mass. I believe something is obviously missing in the official explanation since it does not correlate with what I know of physics. I would support and encourage an effort to accurately determine and explain the behavior of the three structures.

Born in Seattle, Washington, in 1978, I was raised by my parents who always taught me to seek the truth and to be honest with myself and those around me through all my endeavors. My father was the City Planner/Developer of the town in which I grew up, and he had a keen sense of the engineering field as well as the mathematics, physics and science behind it all. I'd like to believe that he passed that sense on to me and that I have been able to develop it through education and experience in the field. It is that sense that told me as soon as I saw the footage of those buildings collapsing on that fateful day that something was amiss.
Having aced a number of college level physics courses in my day, I felt I was being duped when the media/powers-that-be lied to the world in saying that the buildings collapsed due to the airplanes hitting them and the so-called pancake effect. Come on!

My knowledge was only of the Twin Towers collapsed not WTC 7 also. Upon viewing the video of WTC 7, I could clearly see that this was a controlled demolition; as well, as the twin towers. I am no longer convinced that the planes that crashed into WTC were the passenger flights the media informed us about. Unlike the repeated videos aired of the 2 planes crashing into the Towers, I have not seen pictures or videos of Flight 77 crashing into the Pentagon. On the contrary, I have only been able to obtain simulated pictures and videos of footage that shows no plane crashing whatsoever into the Pentagon.

I am not a structural engineer, but even I understand free-fall, and there seems to be a cover-up, for sure, IMO. And not forgetting WTC7, how can a building just drop to the ground like that , without the aide of controlled demolition techniques!

Studied Industrial Design/Interior Design, but always have had ongoing fascination with all things architectural. Declined to enter into architecture studies or career, partly because of 'status quo' forces. I am primarily a very curious novice.
The symmetrical collapses of WTC 1 & 2 always 'bugged me' from the start, the very first day. I heard of the imminent collapse of WTC 7 on radio news later that day, and also thought that was very 'odd'. I kept awaiting a thorough and cohesive structural explanation for how it all happened, but never did hear one forthcoming The more inquisitive I got, the more I followed the paths of other researchers online -skeptical of all at first- but I kept getting pulled-back into their lines of inquiry as more official story elements proved conflicting or extremely incredible. Gradually I had to accept the idea that yes, there are people who'd be happy to exploit the chaos/trauma of 'controlled demolitions' to launch a very broad, global agenda. There is no turning back from this conclusion.

Degreed engineer, concerned citizen and vigilant truthseeker. We WILL put this case together eventually and bring them to justice.
Occam's razor definitely applies here: the idea of a controlled demolition meets all the existing evidence of how the towers (all 3) came down. The ridiculous notion of jetfuel fires melting the steel is suspect enough, but more obvious is the lack of any resistance from the massive steel core columns on the way down, and the lack of any remaining core after collapse. Freefall speed of collapse. Molten pools of iron weeks later. The rubble had NOTHING but handy machine sized chunks of steel..no long members.

Well I have no experience in any field that could be of significance to say anything I'm just concerned with the government of America however I do know the truth when i hear and see it.
I have to agree with the experts when they say it came down by demolition I can see the squibs clearly which I think is enough for me but when the molten lava part came I was shocked how they could say theres no footage no eye witnesses but my eye witnessed this molten steel pouring from the building. How could two buildings designed for the impact of a plane both crumble to the ground at a free-fall pace especially if the fires weren't hot enough to melt the steel? How could anyone believe that the fire was above 1100 degrees celsius? The experts that say that the fire still weakened the building do not explain the presence, discovery, observation, and collection of the previously molten-metal microspheres and unreacted thermite.

I am a house wife but when I saw the buildings come down I knew they were brought down by explosives not by the two air planes.

I took my head out of the sand some year and a half ago after reviewing the two hour on line presentation given by Richard Gage. It was not any single piece of evidence that changed my mind but rather the cohesiveness of the entire presentation that clearly outlined a scenario at odds with the government's version. The most significant red flags that should raise more than an eyebrow are the sliced steel columns with the tell tale slag at the cut off points, the presence of large quantities of molten metal in the debris pile and the extensive forensic evidence of thermite residue in the debris samples. The presence of these particular pieces of evidence should be ample fodder to request a more exhaustive study of the buildings' demise. It is my sincere hope that more Americans can turn a scientific and objective eye to the analysis performed here and shed the false security of ignorance and join us in a quest for truth and justice.
