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.

Based on what I have seen online, it is perfectly clear to me that the twin towers were not brought down by aircraft collisions. The official story appears to be a poor coverup of what really happened that day. I don't think the American people can handle the truth.

Was running a job at the American Express building across the street from the Trade Center on September 11th and never even entertained the idea those buildings would fall. Since then, with the aid of alternative media such as ae911, I have discovered many inconsistencies in the official story.
I was 10 blocks away when the first building fell and never did, and still can't, believe it was due to jet fuel which would have burned in a quick fireball. All materials New York high rises are built with have a low flame spread.

As I watched the collapse occur on the morning of 9/11/01 I was shocked because I had been sure that the buildings would not collapse as I watched for the time between the impact and the collapse. The failure mode made no sense to me as I watched it. I read the article in the New Yorker about the structural engineer of the building about a month later. He wondered if the fault lay in a cost cutting measure at the time of construction that was forced on him - one in which less insulation was wrapped around the steel. He blamed himself for the failure. I find the 9/11 Blueprint for Truth Evidence far more convincing.

I accepted the official story until I watched the footage of Building 7 collapsing. Nothing anyone told me could change my mind. It was the visual of the very obvious controlled destruction that woke me up. When people ask me what I believe about 9/11 I tell them that I don't believe anything, I suspect things. Belief being a black and white decision while suspicion involves a scale of possibilities. My suspicion is very far toward the positive that 9/11 was a False Flag, self inflicted wound, perpetrated by elements within our own government. I am ready to hear more about what this means. You don't have to prove it to me anymore.

I truly believe 100% without a doubt that the WTC was in fact a Demolition/inside Job Caused by the Government to mislead the American people into thinking we were attacked by Terrorist from the Middle East. While in reality, their true intentions were only to inflict war on another country that had absolutely nothing to do with the 9/11 Attacks.

"I remember watching the TV as a 10 year old on September 11th, and thinking to myself, 'If the towers fell down, where did they go? A skyscraper that falls down would make a huge pile of debris'. I've never stopped questioning the official story since that initial issue I saw as an elementary school student. I fully back those at A and E for 911 truth, who are much more educated than I am. They have 'dumbed-down"" some basic principles of physics and engineering, to show the greater population how it is scientifically impossible for what we saw to be the story we were told."

There is no way that the official narrative that we've all been given over the years by our corrupt media can hold up to scientific scrutiny. I no longer believe anything our government tells us regarding 9/11, Sandy Hook, the Murrow Federal building, etc.... we are being lied to constantly. As per William Colby, former CIA director: 'We'll know that our job is done when everything the US population believes to be true, is false.'

All of the evidence points to a coverup, and no matter how much effort goes into perpetuating the official story, the fact remains that the official story on so many counts is simply not supported by the laws of physics. This is why a truly independent investigation is needed.

As a teenager, I worked residential tree service. AA degree in Forest Technology in college. Started my own Tree Service in 1995 when I was 21 years old. My mind works well with engineering and my strengths are technical tree removals with roping, I'm good with patterns and solving problems. This also helps me see fake news or lying in people/employees, etc. I come up with successful ways of solving things and creation of inventions. I just started introducing some of my tool creations recently and last year received a patent on one of my first ones. There are many more to come, I'm sure of it.
I was 28 yrs old when 9/11 happened. I thought it was 'real' at the time, what they claimed. I filled up lots of VHS tapes of the news, for several days (I might be able to find if for some reason someone needs live news footage). 2 years later, I tried to join the Navy, I wanted to go into Seals or Rangers, but I was at the cut off age and no one would get back to me, they were swamped with applicants. Anyway, years later, watching controlled demolitions on YouTube, I woke up on my own and studied them, deciding that was the only way those buildings came down. I then studied all videos of 9/11 that I could. Tried to talk to some family and friends and everyone looked at me like I was crazy, so I stopped that. Now, 2019, I finally find this organization AE911Truth and I don't feel so alone. THANK YOU!

Went to Dunwoody for welding, still do a little bit of that but mainly work in a shop. Oxy fuel cutting works by changing the chemistry of iron ore lowering the melting point by 1000 degrees allowing for you to cut it at 1700 degrees I was told this by an instructor at school can you verify this.
In 4th grade we saw it on TV. The teacher wheeled in to the classroom. I won't forget the events that happened and it even makes it better that it is same propaganda the USA says about it... 9/11 never forget. And never forget the one unverified source that brought us to Iraq to search for nukes we never found.

Joined banking in 2007 right before the house market crash have experience the dirty practices a bank can do by imposing bad practices and sales, heard from my colleges the illegal stuff the bank asked them to do the situations that they put them through, and how they deceived and manipulate people's mind and the system to get away with what they want.
I became aware of the deceit soon after the Las Vegas Shooting in October 2nd 2017, where clearly again they cover up stories and discredit people on what they saw, it was impossible by some specialist that in the short period of time that many people got killed and injured doing the math and calculation on how many bullets needed to take down 58 and injure 200. So since then I have been trying to recollect the events that took place in the same circumstances as LV and 911 felt right on when I kept on remembering the videos I was re watching that clearly have been ignored, erased or vanished from YouTube or the internet all together. After watching some of the real videos that some people might have saved from being forgotten, I could revive some of my memory as well.

I strongly believe that WTC had undergone a controlled demolition of some sort. Several people foretold this event. The people at positions of power had published a pamphlet crying for a new Pearl Harbor for USA to justify military expansions, etc. There are a lot of things about 9/11 that scream for justice. People and victims and the falsely blamed deserve it and will not be silenced. I am also concerned with issues of fair play and transparency in terms of economics, politics and overall worldly issues of importance. That's why I believe 9/11 its victims and general public deserve an honest insight and effort to explain who stands behind this.

Even on that first day that I saw it on television, I realized that the WTC building 7 was demolished. No structural damage, and the entire building falling equally, not to mention the puffs of smoke visible nearly around the side we could see. At that time (previous years), I and my husband were in the habit of watching demolition shows on television (there was a series on TV). We have not watched one since. It also appears that the 'crashing down' of the Twin Towers was also assisted .
