(See the recently published six-part serial essay, Free Fall on Medium.com, by David Chandler for a discussion of freefall and its implications for understanding 9/11.)

Compilation of views of WTC7. The collapse of World Trade Center Building 7 (WTC7), a building with localized fires and not hit by a plane, is one of the most telling events of the day. Yet it has rarely been shown on T.V. since the first-day reporting. A significant fraction of the American public has not seen Building 7’s collapse. Please watch this short video (compiled by Nate Flach) before continuing into this site.

This web site documents the work on the scientific understanding of the events of 9/11 by several independent researchers: David Chandler (retired physics teacher), Jonathan Cole (professional engineer), Frank Legge (PhD chemist), and Nathan Flach (video archivist). We are all independent 9/11 researchers, and affiliated with Architects and Engineers for 9/11 Truth and/or Scientists for 9/11 Truth. Our goal has been to uncover the truth and shed some light on the events of 9/11, each in our own way.

David’s work has been primarily video measurement and analysis of the physics, to come to an understanding of the true nature of the building collapses on 9/11 (see video collection here).

Jonathan’s work is primarily experimental, testing the claims and counter-claims that rage in the 9/11 debate (see video collection here).

Frank Legge (recently deceased — 2016) has worked independently from Australia, as well as collaborating with other scientists in the movement over the years.  He authored or co-authored a significant number of the key scientific papers on 9/11, including the seminal paper, “Active Thermitic Material Discovered in Dust from the 9/11 World Trade Center Catastrophe.”  He participated for several years on the board of the Journal of 9/11 Studies.

Nathan Flach has been a major presence in the background for a long time, as a source of raw footage and an adviser on video issues. He has done a lot of recent work himself on image rectification, which helps bring new details to light.

We are collaborating on this web site because we feel the work done by each of us complements the work of each of the others. Collections of our work (and more) are accessible through the tabs in the page header.

NIST Technical Briefing on WTC7 — David Chandler

David is best known in the 9/11 Truth Movement for proving that NIST lied in denying that Building 7 underwent freefall. Freefall is a literal smoking gun for controlled demolition.  See David’s new 6-part serial essay entitled Free Fall on Medium.com.

David’s work consists of looking at the overall behavior of Building 7 as it comes down in freefall.  Others have looked carefully at the structural details and whether it is possible for the building to come down the way it did due to natural causes.  Most notable in this research is a project by Dr. Leroy Hulsey at the University of Alaska, Fairbanks, who, with two graduate students, has constructed mathematical models in two different finite element analysis systems to simulate the behavior of the structure.  A final report is expected by the end of 2018, but here is an update report as of September 2018.  (The short version is no natural causes appear to be able to produced the observed failures, whereas simultaneous failures in certain columns are able to induce a collapse that closely mimics the observations.)

The Great Thermate Debate — Jonathan Cole

NIST has placed itself in the untenable position of arguing that the buildings of the World Trade Center were brought down by office fires started by jet fuel (kerosene) , which burn 1000°F cooler than the melting point of iron, while, on the other hand they have denied that Thermite, which burns hot enough to melt steel, could do the same job. Watch this video for a dose of reality, … Jonathan at his best.

[By the way, the seminal paper, Active Thermitic Material Discovered in Dust from the 9/11 World Trade Center Catastrophe, is available at the Bentham Open Chemical Physics Journal web site. If you can’t find it at the Bentham site, try this alternative direct download link.]

We are in agreement, and in agreement with over 2000 architects and engineers who have signed the petition at AE911Truth.org, that the so-called “investigation” we have been given by the government is nothing more than an elaborate, expensive cover-up.

So, how do we respond to the atrocities of 9/11?
Here are a few thoughts.

AE911Truth recently produced a major feature-length video entitled 9/11: Explosive Evidence — Experts Speak Out which is available on DVD or for download from the AE911Truth.org web site. There is now a slightly shortened 1-hour version on YouTube (and shown here) which was shown on Colorado PBS and became the most watched video in that station’s history. For a time it was also the most viewed and most shared video on the national PBS website. This is a breakthrough for exposure of our research on the mainstream media, where it is more typically treated as a taboo subject.

9/11 Analysis DVD with David Chandler

The 9/11 Analysis DVD project is a compilation of the many short analysis videos David Chandler has produced and uploaded to the Internet, woven together with an interpretive narrative.
Low cost 25-Packs in paper sleeves (marked “Not for Resale for Profit”) are available. They may be given out free or sold at cost.

The International Hearings on the Events of September 11, 2001
(Also known as “The Toronto Hearings”)


The 2-hour video summary of the Toronto Hearings, “9:11 Decade of Deception” is now available on YouTube. See the Toronto Hearings tab in the main menu above to view the whole DVD broken into an introduction and day-by-day segments.

The printed Proceedings have been published and are available from Amazon.com.

Another short, well produced video from AE911Truth is Architects and Engineers: Solving the Mystery of WTC 7, narrated by Ed Asner.

It is generally thought that the academic community approaches significant issues without bias. However there appear to be significant pressures on the academic community with regard to 9/11, as this video documents: 9/11 in the Academic Community.


The Association for Nine Eleven Truth Awareness (ANETA) hosts an annual “Physics of 9/11” debate in which physicists or physics professors are invited to support the official story in a debate with a physicist or physics professor from the 9/11 Truth Movement. In the 5th annual debate David Chandler was invited to represent the position challenging the official story and (as has been the case each year so far) no one stepped forward to represent the official story. Hence the “debate” becomes a discussion. The 5th annual “discussion” seen here focuses on the collapses of WTC 7 and the North Tower.
