Bazant, Le, Greening & Benson . Journal of Engineering Mechanics ASCE, Vol. 134 (2008). Refutation of controlled demolition theory. Discusses matching of video record with progressive collapse equations, "free-fall" claims, concrete crushing (and how much TNT equivalent would be needed to do that crushing), air pressure & ejection of air, spread of dust cloud.

February, 2009: Richard Gage's Architects & Engineers for 9/11 Truth out-does itself:



"On." NASA scientist Ryan Mackey's comprehensive critique of David Ray Griffin's claims about the collapse of the World Trade Center buildings. Essential reading for conspiracists, skeptics, and anyone who wants to know how incompetent, dishonest, and wrong even the "best" of the 9/11 conspiracists are. 306 pages. PDF or doc file.A poll written by a truther and sent only to truthers. Very interesting! The JREF forum and I were voted to be the most effective opposition to the truth movement. 2007 Truth Movement Poll

August, 2008 : NIST's draft report on the collapse of WTC 7 has been released for public comment. Click here to download the full report in pdf form. NIST's press release and other material on the report can be found here Video of NIST press briefing about the release.



July, 2008 : The BBC TV program I'm in briefly, "The Conspiracy Files–9/11–The Third Tower" is an

outstanding examination of why the WTC 7 conspiracy theories are nonsense.





July, 2008: The two Hardfire shows with myself and Richard Gage, head of Architects & Engineers for 9/11 Truth, are now online. The host is 9/11 conspiracy believer John Clifton. Here's some info on the shenanigans they pulled to try to get the upper hand before and during the shows. Or, save time and just go to this point in the second show when Gage "jumps the shark" and displays his staggering ignorance of structures and engineering for all to see. Funny how Gage didn't promote these shows before or after they aired!

Thanks, Richard, and good night, "truth" movement!

Hardfire producer Gary Popkin sent an email to myself, John Clifton, and Richard Gage, saying that the north tower collapse does look very impressive from the truther point of view: that the top seems to be disintegrating and perhaps loses a lot of mass over the side. I sent this email to those three men in response. It covers that and several other points, and is a good place to start for people who wish to examine Gage's claims on the shows. I'll have a few pages here devoted to more of his nonsense shortly.







My correspondence with Richard Greene of Air America, concerning his shows featuring some of the most severely disturbed and delusional truthers.



Truther competence at its finest. A guy who who runs a blog titled "Debunking the Debunkers" trumpets that he's debated me, publishes the debate, and spreads it around the internet. The problem? He wasn't debating me or anyone who claimed to be me . I guess the question "Are you Mark Roberts?" never occurred to this person, who bills himself as an "investigative journalist."As promised, many of theThere is a wealth of material online, with more to come. Contrary to William Rodriguez' repeated claims that his June, 2004 interview with Commission staffers was covered up, the staffers' notes of that interview are now public. Mike Williams of 911myths.com has obtained, scanned, and made available those notes here and here (pdfs). Rodriguez has said that his story hasn't changed since day one, yet in this interview, as with his statement to NIST, he makes no mention of suspicions of bombs in the basement, of suspicions that the attacks were a U.S. government "inside job" that was covered-up, or that his accounts were ever censored by the media. See my thorough examination of these claims here. I turned down all interview requests around Sept. 11 this year, including from popular TV shows in New York, Toronto, and London. However, I was honored to be interviewed on video, along with psychology professor Dr. Mark Henn, by Kylie Sturgess, winner of the 2007 Australian Skeptics Prize for Critical Thinking. This was for the inaugural edition of The Skeptic Zone , which is now Australia's most popular podcast for social sciences. Kylie had questions prepared, but Mark and I started chatting, and she decided that was interesting and entertaining enough to record as is. I hope you agree! (The show is titled "9/11 Truthers Debunked," but it is a post-mortem of the "truth" movement and not an examination of specific claims.)
