February, 2009. Hi there. I've only spent a few hours updating this site since early 2008, and won't be updating it in the future unless big news arises. I have several hundred links that I could add to the several thousand here, but enough is enough. The 9/11 "truth" movement has dried up and blown away, having achieved none of its stated objectives or even bothering to get a single significant claim correct. See the "What's New" section below to get an idea of the type of people who still cling to kooky 9/11 delusions.

However, let's remember that 9/11 won't be the last major internet-age event about which people with agendas – whether they be government spokesmen or basement-dwelling crackpots – aggressively spread falsehoods. Unfortunately, falsehoods about the 9/11 attacks have their strongest foothold in Muslim countries (see poll results below), where this website has no effect.

February, 2011. In response to numerous requests, my 47-minute video "World Trade Center Not a Demolition" is online again, generously hosted by Mike Williams of 911myths.com Mike has also posted a smaller version of the video for people with slow connections.

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.

Featured paper:."On Debunking 9/11 Debunking." NASA scientist Ryan Mackey's comprehensive critique of David Ray Griffin's claims about the collapse of the World Trade Center buildings.

What's New?

November, 2009: Ryan Mackey meets mechanical engineer Tony Szamboti (aka realcddeal) on Hardfire. Show 1. Show 2. Show 3.

March, 2009:
NASA/JPL scientist Ryan Mackey has taped three Hardfire shows with Ron Wieck, about the physics of 9/11. The first and second shows are up, and I've got the full PowerPoint presentation here. Now here's show 3.

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

We've seen the staggeringly ignorant and outright bizarre nonsense spewed by Gage and the "experts" whose opinions he promotes. Is Björkman's promotion by AE911Truth another fallacious appeal to authority? Has Bjorkman done some sensible analysis of the events of 9/11, or is he one of the most flagrant crackpots in the entire "truth" movement? Judge for yourself with the help of this summary of his opinions. (Bjorkman posts as "Heiwa" on the JREF forum.)

February, 2009: 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."

January, 2009: As promised, many of the 9/11 Commission investigation records have been made public. There 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.

September, 2008: 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.)

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. 6 Debunked Conspiracy Claims from Today's NIST (WTC 7) Report.

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.

Popular Mechanics "Debunking the Myths" magazine cover story March, 2005
Some critics claim that we "cherry-picked" sources who would be favorable to our "agenda." The fact is, for each question we studied, we simply approached the top experts in that particular field. The irony is that we were unable to find anyone with any degree of authority, in the public or private sector—first responders or university professors, engineers or flight instructors—who agreed with the claims made by 9/11 conspiracy theorists.

Penn: "Nobody can convince me?" Bells should go off in your head when you hear those words. That's his bullshit idea of skepticism. A real skeptic demands to be convinced – with evidence. We should be skeptical of our government, but we shouldn't just make shit up."
