This training, certification, and work experience leads these 1,000 architects & engineers to know, collectively, that the 2 World Trade Center buildings (WTC 1 and WTC 2) were not destroyed by aircraft impact and fires alone. And, now that they know about the "collapse" of World Trade Center 7 (WTC 7) at 5:20 that fateful afternoon, they understand implicitly that it was brought down by a classical "controlled demolition" — not fires.

The Architects & Engineers for 9/11 Truth (AE911Truth) organization was born in 2006, an inspiration of Richard Gage, AIA, (a professional licensed architect) to "call upon Congress for a truly independent investigation with subpoena power" and to alert his follow architects/engineers to the evidence for the planned explosive destruction of all three WTC buildings.

Recently, through Mr. Gage's speaking tours, video analysis by physics teacher David Chandler, and a strong web presence, the AE911Truth petition now has over 1000 architect and engineer petitioners whose credentials (degreed and/or licensed) have been rigorously verified. Over 6000 others have signed the petition indicating their support. While we celebrate this momentous achievement, we ask all readers who have not signed the petition, to do so. The evidence will be obvious to all – but especially to those trained in basic physics, engineering, building design/construction, or statics and dynamics. Please read the articles as time is available to familiarize yourselves with some of the more technical evidence, or, if you like, do your own research.

Summary of Petition Signatories

Who are these architects and engineers who have signed this petition and how are their technical qualifications established?

Taking the last point first, here are the rigorous steps taken by the AE911Truth Verification Team to ensure their technical qualifications:

Petitioners are asked to make a brief statement of their reasons for signing the petition. Three of these petitioners and their statements deserve mention at this point.

Paul Oles, FAIA, a practicing architect in Santa Fe, NM, is a member of the College of Fellows of the American Institute of Architects (FAIA). He states:

There appear too many unexplained events and unverified circumstances to be satisfied with the official version of the New York building collapses. As unthinkable as it is to suspect the … government … of willful complicity …, it is even more heinous to allow such complicity — if indeed it exists — to remain undiscovered …. Therefore, a thorough and impartial investigation by an independent, well-funded commission is fully merited.


<name redacted by request> is a structural-civil engineer with a Professional Engineering license in New Jersey. With first hand knowledge of the early FEMA report 403, he notes:

FEMA investigators have discovered and documented evidence of molten (liquid) steel found in the debris of WTC 7 and in the debris field of WTC1 and WTC2.

I point to "FEMA 403 - World Trade Center Building Performance Study / May 2002, Appendix C: Limited Metallurgical Examination, Section C.2" which states 'Evidence of a severe high temperature corrosion attack on the steel, including oxidation and sulfidation with subsequent intergranular melting, was readily visible in the near-surface microstructure. A liquid eutectic mixture containing primarily iron, oxygen, and sulfur formed during this hot corrosion attack on the steel.'

However, to date it does not appear that FEMA has pursued further study into this critical issue. It appears that FEMA investigators have been prevented from completing/furthering their study.
…When will our demands for an Independent Investigation be heard?


Ronald Brookman is a licensed structural engineer in the state of California with over 21 years experience in structural analysis, design, evaluation and rehabilitation of buildings in northern California. He states:

After much reading and studying it is obvious that NIST, FEMA and the 9/11 Commission have all fallen short of a detailed accounting of the catastrophic collapses of the three World Trade Center buildings in Manhattan on 9/11/01. A few examples of unexplained details include … the complete symmetrical collapses following asymmetric structural damage and short-term fires, and the chemical signature of incendiary compounds found in the toxic WTC dust.

I would really like to know why complete collapse of the twin towers 'became inevitable' as expressed by NIST without any scientific analysis to substantiate it. Why would all 110 stories drop straight down to the ground in about 10 seconds, pulverizing most of the contents into dust and ash - twice? Why would WTC 7 fall straight down to the ground in about seven seconds the same day? It was not struck by any aircraft or engulfed in any fire. An independent investigation is justified - and necessary - for all three collapses.

Now, for an accounting of the architects and engineers, as a whole:

Architects comprise about 29% of the petitioners. Contrary to popular belief, most architects are not merely designers. On each building project architects consult with structural engineers (of which we have over 40 petition signers). Much time is spent ensuring that the structural engineering is sound and can withstand the rigors of wind, rain, and fire.

The remaining 71% of signatories are engineers. The distribution within engineering for these degrees is shown in the pie chart.

As students, engineers are trained in basic physics, chemistry, statics, and dynamics in the general engineering classes before they begin specializing. Each discipline brings unique knowledge to the analysis of evidence pertaining to the destruction of the WTC high-rise buildings.

There are no doubt hundreds of other scientists – physicists, analytical chemists, pilots, fire fighters, and image analysts that also have unique capabilities to assess the WTC building destructions. They are not included in the list of architects or engineers. They have their own organizations providing information, testimonials and voices coming from their unique technical backgrounds*.

Among physicists that know the falsity of the government's official explanations is AE911Truth petition signer Dr. Steven Jones (former physics professor at Brigham Young University, removed due to his courageous stance on the 9/11 explosive evidence). He wrote an influential paper** that gives 15 solid evidence points for the hypothesis of the explosive destruction of the Twin Towers. Mr. Chandler has analyzed the WTC videos showing evidence of explosive ejections and other factors not consistent with the official gravitational collapse story. Our list could be much longer if we included all applicable fields of study and if we merely believed quoted credentials.

Our 1,000 architect and engineer petition signers can assure you that the explanations by the NIST authors that aircraft impacts and fires resulted in free-fall collapses through the paths of greatest resistance, is simply not possible. Many choose to believe the official explanation to avoid having to deal with the consequences of such a conclusion — namely that all 3 WTC buildings must have been pre-planted with explosives for demolition (WTC 7 through a classical controlled demolition and the two Twin Towers through an outwardly explosive event).

The 1,000 petition signers of AE911truth demand an open investigation with subpoena power. All observational history and all collected evidence must be thoroughly evaluated by an independent team. Let the chips fall where they may. Our architects and engineers have done their patriotic duty.
