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.

When I watched the collapse of the WTC buildings, I knew there was something fishy about the whole affair. No building of that size goes down in free-fall speed, and collapses in his own foot-print. It looked to me more like a typical controlled demolition with explosive charges, remember the King Dome in Seattle. Jet Fuel is like Kerosene with a low flame point, its fire temperature is never high enough temperature to melt steel. There was a high-rise in Madrid that burnt for days without coming down.

I have a mechanical engineering and structural engineering background. The bulk of my experience has been in construction and special devices engineering. I have provided automotive, aerospace and medical equipment companies with answers to many functional situations for operations as well as daily use of devices that I have either developed or partnered with developers to manufacture.
The entire scenario of how the buildings fell especially the height and rate of fall does not correlate to any know demolition except for a controlled or planned demolition. I also can not accept the findings of the 911 commission due to the absence of critical data such as thermite presence and witnesses who claim there was an explosion before the planes hit. WTC7 is a complete mystery all its own. This country, the victims and the survivors deserve better than what has been furnished and it should be viewed as treason to expect the public to swallow this entire situation as it has been presented by our government.

My thoughts are a pancake of floor down to next floor would have created a uniform dust blast in all directions, like dropping a book on a dirty garage floor, not individual squibs in certain spots. I did not see uniform displacement, I see squibs. I hear too many eyewitnesses reporting explosions in different parts of the building. Clip of firefighters is key, boom boom boom all the way down, like a controlled demolition. More than one source reported that the firefighters knew bldg 7 was about to be pulled. Compare film of other controlled demolitions; building 7 was a planned, controlled demolition.

I've worked for 10 years as a process engineer in multiple industries including, Iron and Steel Pipe, Pulp and Paper, and Nuclear Separations. My primary engineering role is now process control. I worked for two years in the Melting Department at a Ductile Iron Manufacturing plant.
From first hand experience, the process of melting solid iron or steel requires enormous amounts of energy either in an arc furnace or a blast furnace. We did not use hydrocarbon fuel or burning office supplies to melt the iron. There is ample evidence on this website to compel a new investigation: molten iron, chemical signatures of thermate, lack of pancaked floors, multiple eye-witness testimonies of explosions before the collapse. Mr. Gage and others like him are heroes for standing up for our country and telling the truth about what really happened on 9/11.

The families of the victims were paid off in legal settlements without ever having the satisfaction of a full investigation of the events of 9/11...Why??? This investigation should include the fall of the buildings and all of the events of that day.

Using high school physics, it is impossible for buildings of this type to collapse from any type of upper floor damage, in the time taken. Examine the videos, frame by frame, adjusting brightness and contrast, you will see bright flashes throughout the building. Evidence for explosives.

I strongly believe that there is enough evidence to reopen an independent(!) public investigation. I cannot believe that planes can make a building as big as WTC fall. Logically, I don't understand why the building 7 fell without being hit by anything and, most importantly, why is there no report on his collapse. As I know it, every investigation after an accident, like airplane crash, begins with a meticulous identification of the debris for further investigation. Why was this disaster site cleaned so fast ?!?

I was working out of my home that morning. My wife called me into watch the TV after the first plane hit. When I saw the buildings collapse it was clear to me that it had to be an inside job and I let my network of friends and activist know. I was called names and lost a number of friends due to that. I remain convinced and have seen no reasonable evidence that explains the collapse otherwise.

Why did the papers not publish (Anti aircraft weapons mounted on the roof of colony beach and tennis resort and the visitors of mid-eastern descent, that wanted a meeting with Bush the morning of 9-11). Where does this fit in. Its a no brainer that these buildings were imploded. Why would building WTC #7 fall to ground, no plane hit it.

I agree with Paul Craig Roberts that speed of collapse is sufficient to make the case. The debunkers claim there was unseen damage to WTC. That does explain speed of collapse or straight down fall.

Grew up on Long Island in Valley Stream, not far from the towers. Was at work when they fell, watched the whole thing on the news and was terrified. Immediately knew that those two planes could not have brought down the towers. Further research on my own proved my hypothesis and I am now a part of the truth movement.
My main concern is the foundational steel found which demonstrated that it had been destroyed by a demolition or a planted explosion. The angled breaks suggest a planted explosive since the foundational steel did not buckle.
