Welcome to Architects & Engineers for 9/11 Truth.

Below is a summary of information that we feel you need to know regarding the events of September 11, 2001, in New York City.

AE911Truth has carefully studied the publicly available information on the destruction of World Trade Center Buildings 1, 2, and 7. This evidence includes video and audio recordings, photographs, eyewitness accounts, and physical evidence.

As building and technical professionals, we research and comment on only this forensic and recorded evidence, which has led us to the inevitable conclusion that the three skyscrapers were willfully destroyed by controlled demolition using explosives and incendiaries. That is why we have concluded that the hypotheses for the buildings' destruction given in the official reports published by the National Institute of Standards and Technology, an arm of the U.S. government, are seriously flawed and scientifically impossible.

The Evidence

 AE911Truth's - Blueprint for Truth - The Architecture of Destruction (33-min. version)

This 33-min. version of the original two-hour AE911Truth film, presented by Richard Gage, AIA, takes the viewer through the most of  the scientific evidence that proves, beyond a reasonable doubt, that the destruction of the World Trade Center was accomplished with explosive controlled demolition.

Explosive Testimony

 These and other experts are featured in our latest documentary "9/11: Explosive Evidence - Experts Speak Out" 

The one hour version of the film is below...

WTC 7: NIST Finally Admits Free-fall (Part I)

In its draft report, released in August 2008, NIST attempted to cover up evidence that WTC7 fell at free-fall, but the cover-up was transparent. In its final report, released in November 2008, NIST finally acknowledged free-fall, but couched it in a bizarre framework that continues to deny its clear significance. This video displays the brazenness of the NIST WTC7 cover-up.

9/11 Experiments: The Great Thermate Debate

Jonathan Cole tackles the thermate debate. Can thermate actually cut steel or is National Geographic's 9/11 show correct?

118 Witnesses:  Firefighters Testify to
Explosions in the Twin Towers

Reminder: This YouTube video is not an AE911Truth video, and AE911Truth takes no position on who is responsible for the 9/11/01 attacks.

When a small team of independent researchers can discover major discrepancies and careless errors throughout what should have been the most critical and carefully reviewed part of the entire report, then what confidence should anyone have in the rest of that report, or NIST's other reports about what happened on 9/11? 

Part One — Shear Ignorance

Part Two — The Expanding Lie

Part Three-- Tangled Webs

Part Four-- MaladmiNISTration

"But Hasn't Popular Mechanics debunked this?"

No. 

One of the reasons we frequently hear for why people do not look further into the evidence of controlled demolition on 9/11 is because they have heard that the evidence has been "debunked" by Popular Mechanics.   AE911Truth has developed a series of articles that exposes the fallacies and flaws in the arguments made by Popular Mechanics in the latest edition of its book, Debunking 9/11 Myths.
