You’ve probably seen the grainy footage. A massive steel-framed skyscraper drops into its own footprint in under seven seconds. It looks clean. It looks surgical. For most people, that 2001 afternoon was a blur of trauma, but for a specific group of technical professionals, those few seconds of video didn't just represent a tragedy—they represented a massive middle finger to the laws of physics as they understood them.
Enter Architects and Engineers for 9/11 Truth.
They aren't your typical tinfoil-hat crowd. We’re talking about people who spend their lives calculating load-bearing capacities and thermal expansion coefficients. When Richard Gage, a member of the American Institute of Architects, founded the nonprofit back in 2006, he started a firestorm that hasn't really stopped since. The group has grown to include over 3,500 verified architects and engineers who all signed a petition demanding a new, independent investigation into the destruction of the Twin Towers and, perhaps more crucially, World Trade Center Building 7.
Honestly, it’s about the science. Or the perceived lack of it in the official reports.
The Bone of Contention: Building 7
Most people remember the Twin Towers. Very few people—unless they lived in Lower Manhattan—vividly remember Building 7. It wasn't hit by a plane. It sat across the street. Yet, at 5:20 PM on September 11, the 47-story skyscraper collapsed completely.
The National Institute of Standards and Technology (NIST) spent years looking into this. Their final word? Normal office fires caused "thermal expansion" of the floor beams, pushing a girder off its seat and triggering a progressive collapse. Architects and Engineers for 9/11 Truth calls foul on this. They point to the 2.25 seconds of literal "free-fall" acceleration that NIST eventually acknowledged.

You can't have free-fall if there's structural resistance. That's basic high school physics. If a building is falling at the rate of gravity ($g \approx 9.81 m/s^2$), it means the floors below aren't doing anything to slow it down. They’re just... gone.
The University of Alaska Fairbanks Study
To back up their skepticism, the group funded a four-year computer modeling study at the University of Alaska Fairbanks, led by Dr. Leroy Hulsey. This wasn't a basement project. It was a rigorous finite element analysis.
The results? Hulsey and his team concluded that the NIST model didn't hold water. They found that the simultaneous failure of every column in the building was the only way to replicate the observed collapse. It’s a dense, 100-page report that basically says "fire didn't do this." Whether you believe the implications or not, the math in that study is a massive hurdle for the official narrative to clear.
What Drives the Skepticism?
It’s easy to dismiss "truthers" as a monolith, but this specific group operates differently. They focus on the mechanics. For instance, they often bring up the "squibs"—those puffs of dust and debris seen shooting out of the Twin Towers several floors below the collapsing "crush zone."
Official reports say this was just air being compressed as the building pancaked. The engineers in this group disagree. They see high-velocity ejections. They see the signature of controlled demolition. They talk about the "moly-coated" micro-spheres found in the dust—tiny droplets of once-molten iron that imply temperatures far higher than what burning jet fuel (which is basically kerosene) or office furniture can achieve.

Jet fuel burns at maybe 800°F to 1500°F in open-air conditions. Steel doesn't even start to melt until about 2750°F. While NIST argues the steel didn't need to melt, only weaken, Architects and Engineers for 9/11 Truth argues that the presence of molten metal in the debris (reported by numerous first responders like FDNY Captain Philip Ruvolo) proves something else was at play.
The Backlash and the Credibility Gap
Look, being an architect who signs this petition isn't exactly a career-booster. People have lost jobs. They've been sidelined. The mainstream scientific community generally sticks with the NIST findings, arguing that the sheer scale of the 9/11 attacks created "unprecedented" structural conditions that traditional models can't easily replicate.
Critics of the group say they are cherry-picking data to fit a preconceived "demolition" theory. They argue that the group ignores the massive structural damage caused by the debris from the North Tower hitting Building 7.
But the group isn't just Richard Gage anymore. It includes people like Roland Angle, a civil engineer with over 50 years of experience. These aren't kids. These are the people who design the bridges we drive over. When they say "the math doesn't check out," it carries a different kind of weight than a random YouTube comment. It forces a conversation about transparency and the limitations of government-funded science.
Why This Matters in 2026
We live in an era of intense institutional distrust. Whether it’s public health or national security, people want to see the "receipts." Architects and Engineers for 9/11 Truth tapped into this long before it was the cultural norm.

Their persistence has led to some minor legal victories, including a 2021 ruling that forced the FBI to disclose more information about their "PENTTBOM" investigation. They aren't looking for a "conspiracy theory" label; they’re asking for a peer-reviewed, transparent forensic audit of the evidence.
Basically, they want the data sets NIST used for their computer models to be made public. NIST has refused, citing "public safety" concerns—which, as you can imagine, only fuels more suspicion. If the models are accurate, why not let every engineering school in the country run the numbers?
Actionable Steps for the Curious
If you're looking to dive deeper into the technical side of this debate without getting lost in the weeds of internet rumors, here is how to approach it:
- Read the Hulsey Report: Don't take a summary's word for it. Look at the University of Alaska Fairbanks "Structural Analysis of WTC 7" report. It’s technical, but the visualizations of the column failures are eye-opening.
- Compare the NIST NCSTAR 1-9 Report: This is the government's final word on Building 7. Read the section on "Thermal Expansion" and see if the logic of a single-point failure causing a total collapse makes sense to you.
- Watch the "Beyond the Evidence" Series: The group has produced several documentaries that feature interviews with high-rise architects. Look for the technical explanations of "shear studs" and "girder seats."
- Verify the Signatories: You can actually look at the list of professionals who have signed the petition. Many include their license numbers and firms. It’s worth seeing the caliber of people involved before dismissing the movement.
The reality is that for Architects and Engineers for 9/11 Truth, the case isn't closed. It’s a cold case, perhaps, but one where the physical evidence—at least in their eyes—still contradicts the official testimony. Whether you’re a skeptic of the skeptics or someone who thinks the buildings came down with help, the technical questions raised by these professionals remain some of the most persistent "glitches" in the history of modern structural engineering.
Understanding the specific mechanics of the "Global Collapse" vs. "Progressive Collapse" theories is the only way to move past the rhetoric and into the actual science of what happened that day. If the goal is truly "never forget," these professionals argue that we shouldn't forget to get the math right, either.
