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.

On 9/11, I was just starting 7th grade, throughout the day students were leaving class to go home, they were being picked up by their parents. The students in middle school, such as myself, had not been told of what happened, they only told the high school students for some reason. When I got home my father surprised me because he was home early. As I walked into the house I saw him watching CNN. They were just showing the video of the collapse and the towers burning earlier that day. He told me that the Department of National Defense, which he worked for, had sent everyone home after the second plane hit. My initial reaction after seeing the footage of the Twin Towers collapsing was: It looks like a controlled demolition. My father went on to tell me that Arab extremists had attacked the building by flying hijacked planes into it and that the impact of the planes had caused the buildings to collapse. I repeated again But it looks like a controlled demolition. Of course at the time I was only 12 years old and did not realize the implications of it being a controlled demolition. After watching the TV footage CNN had on replay, I later asked him Why would anybody attack a building full of innocent people. It doesn't make sense. He replied: Well that's Muslim extremists for you, they're just crazy. It just didn't make sense to me. That is all I really remember from my experience on the day of September 11th 2001.

Overwhelming physical evidence proves the three buildings were intentionally demolished. Building 7 owner Mr Silverstein is on record saying he gave permission to pull it. Rather than preserve the scene and evidence, the beams were immediately trucked away for recycling. The three top members of the 9-11 commission say their report is a cover-up because the government withheld information, gave false info, under funded the investigation and rushed them to conclude. The truth must be promulgated.

Knowing the basics of structural engineering, controlled demolition appears to be one of the only explanations of why WTC building 7 fell--and possibly the towers. Building fires do not cause steel-framed buildings to collapse. I am unclear why the government would not want an independent scientific investigation involving some of the most respected architects and engineers to take place in the absence of solid conclusions drawn in the official 9/11 report.

My questions focus on #7 WTC. There can be no doubt that it was a controlled demolition. The only question is why was it done on that day. And if there were any doubts, why can't the circumstances be more fully examined? - - A B-25 bomber flew directly into the Empire State Building on a Saturday, and the building was open for business the following Monday, with the exception of the most adversely affected areas near the top. - - Different type of aircraft - different type of building. But it is difficult to reconcile that instance with what happened to 7WTC on 9/11.

I have looked at the collapse of 7 WTC many times and while I don't believe in conspiracies, I can't get past how clean the collapse was. I would really value Eve Hinman's opinion on this. I continue to believe that the towers fell as a result of the planes and fire but I am continuing to keep an open mind about 7.

After watching a PBS video I am convinced that the Twin Towers and WTC #7 were packed with internal explosives that led to their implosion. I think an independent investigation needs to be conducted based on scientific facts and eye witness accounts of why these buildings fell and so quickly. Why #7, who was not hit by an airplane also imploded.

If you apply much of the so-called logic, so-called science and so-called expert advice as to the government position on 9/11 Twin Towers destruction, then how do you explain Building 7 falling as it did other then by professional demolition, logically speaking? It seemed more like 'just because' science, reasoning and logic made by just because professional experts. I think these same people could make a case for pigs flying in heaven. On 9/11 I remember thinking, after seen the Pentagon in smoke allegedly hit by a plane, where was the debris and human carnage?

The destruction of the 9/11 Towers has made the world a much worse place to live- give us the truth to move on to a better one. I lived in the US for more than 10 years so its people are dear to my heart. However if the US can't begin to accept its actions and place in the world as a whole, what hope is there for societies that are supposedly less open?

WTC7 has been destructed intentionally. It cannot be otherwise. People just have to take a few minutes to see the video of collapse and hear the comments. AE911 truth is the last chance to make people wakened. Everybody must help by transffering the petition to friends and family. I hope to see the final act before I die.

There is enough evidence to demand a re-investigation into what happened on the 11 of September 2001. Any government in a democracy has a responsibility to serve the best interests of its people and therefore the demand for a new investigation can simply not be ignored if there are enough citizens demanding for it to happen. The American government needs to understand that the truth will never go away until it has been surfaced. Coming from England I feel their needs to be a worldly campaign in order to get enough people talking about this new investigation, and if that happens then the media will not be able to stop themselves from publishing about the need for the truth. 9/11 affected the whole world, its about time the world did something about it for the good of those families affected by it. If it is found that government was responsible for 9/11, then trust between Americans and the government died on that day too.

I have never believed that the Sept 11th attack was not in some way the responsibility of factions in the American government. As the years have progressed that conviction has solidified. Americans are sleepwalking into the nightmare of Fritz Lang's 'Metropolis' and Orwell's '1984' if they don't wake up soon and investigate fully the criminal activity of that day....and then punish those involved. It's not just the American people who are/will suffer. The rest of the world feels the consequences acutely.

I am appalled by the gross and obvious misdeeds and intentions of the 9/11 attacks and want the rest of the general public to know who was really behind the attacks, what they were really for, and who needs to be imprisoned or killed because they're at fault. I don't think we'll ever really find out, but a reinvestigation is a step in the right direction.

Amazing to think that some organization could have actually planned a scheme like this. Why have planes hit the buildings if you can just detonate them? It would have still been looked at as a terrorist attack? Also, with so many people involved in such a large undertaking, you would think that someone would have decided to become famous and speak out. Just really hard to wrap my arms around this entire concept although from a scientific view point, it makes perfect sense.

I have a general understanding of physics from school and personal interest. I've designed, drafted and had built a 1-1/2 story timber-framed structure.
I cannot reconcile the laws of physics that an organic event, such as the fires started by the impact of the planes, with the symmetrical collapse of the three buildings. Neither can I understand how any report of an incident which is so massive in the scale of evidence could have been accurately investigated and conclusions written within mere months from its occurrence.

I'm not religious, I'm not proud to be an American. I grew up in a country being fed lies and deceptions. I know this because I'm a seeker of truths and sciences. I spend my time on my computer, like anyone else, learning about what I find interesting; that being, nerdy sciences, etc. I'm a 'where's the proof?' kind of person. The proof I see, more and more each day, makes me sick. That this country is so destructive toward it's own people. Whether it's news, companies/businesses, the (sad excuse of a) government, the food industry, etc.. I'm fed up.
I watched and heard the news while I was at high school, in SE California, and the more I saw/heard/read, the more I knew something wasn't right. Why? How? That's not possible? - I knew then, a 9th grader, that a plane (alone) couldn't take down an iron structure like that the way it did. I excelled at math and science through most of my life, and common sense is all that's needed to know there's something wrong with the stories we were being fed. Sure, terrorists may have had something to do with the airplanes, but what can be said of the rest of the damage? If it was covered up so well, it's safe to say our government or a well financed organization had something to do with it. The government would've had no reason to cover up a foreign terrorist attack. There is absolutely NO excuse for not investigating every aspect of the situation, NONE. Be it religion or your own belief system, you do what needs to be done for justice. For the truth!

I guess I am like so many who don't want to think our government could, in any way, be involved in this disaster. I did not know about WTC #7. Your information is astounding and I can't believe anyone who watches this would not find it a little confusing. As one of the people on the video said, it, too, makes my stomach not feel very good. I, too, think an independent investigation should be done.
