Steven Dusterwald

37-Year S.E. Structural Engineer

"What caught my attention was the rapid failure of connections that had to happen in order for Building 7 to come down at the rate that it did."

Rick Fowlkes

P.E., 40-Year Civil/Structural Engineer

"On Sept. 11 when I saw the Twin Towers coming down, I knew that it had to be controlled demolitions we were witnessing."

Robert McCoy

High-Rise Architect

"I signed the petition for AE911Truth because I felt it was an organization that was trying to get at the truth of what actually brought those buildings down on 9/11."

Roland Angle

P.E., Civil/Structural Engineer

"What really concerns me is we're beginning to live in a society that is rebellious against science. It's important that all of us with the technical expertise speak out on the 9/11 issue."

Alfred Lopez

S.E. Structural Engineer

"In Building 7, we have a total collapse against 40,000 tons of structural steel at free-fall acceleration, and that doesn't make sense."

Kamal Obeid

S.E. Structural Engineer

"Structural engineers and other building professionals need to understand that these buildings did not fail the way they are claimed to have failed."

William Brinnier

25-Year Architect

"Not hit by a plane, with small fires and little damage from debris, there was just no logical explanation for Building 7 to come straight down through what was the path of greatest resistance in under 7 seconds."

Dan Barnum

FAIA, High-Rise Architect

"The tops of the buildings were basically disintegrated."

Tom Sullivan

Explosives Technician Former Controlled Demolitions, Inc. Employee

"I knew from day one this was a controlled event. What I saw was a classic implosion. The center of the core; the penthouse area starts to move first, and then the rest of the building follows along with it."

Jody Gibbs

35-Year Architect

"The Twin Towers fell at a speed which can only occur if the vertical structure has been removed."

Richard Humenn

P.E., Original WTC Chief Electrical Design Engineer

"Knowing the strength of the structures, it was unbelievable to me that plane impacts and fuel burning would be the only reason for the Twin Towers to collapse. The only way they could have collapsed was if the core columns were compromised."

Frank Cullinan

P.E., Civil Engineer

"It was shocking how fast the buildings collapsed. Tens of thousands of structural connections had to fail not only nearly simultaneously, but in sequential order."

Anthony Szamboti

B.S.M.E., Mechanical Engineer

"The tons of molten metal under just the three WTC buildings that collapsed made me realize that what we're being told about how they collapsed is false."

Gery Warner

P.E. Mechanical Engineer

"Molten aluminum is silver. It looks like mercury. The molten metal pouring out of the South Tower is indicative of molten iron, not aluminum."

William Rice

P.E., Civil/Structural Engineer

"Watching Building 7 collapse in under 7 seconds, after watching the Twin Towers collapse, I think most anyone would recognize these as controlled demolitions."

Scott Grainger

P.E., Forensic Fire Protection Engineer

"Structural steel frame high-rise buildings simply do not collapse due to fire."

Ed Munyak

P.E., 25-Year Fire Protection and Mechanical Engineer

"Even one global collapse would have been extraordinary, but to have 3 occur in one day was just beyond comprehension."

David Chandler

B.S Physics, M.S. Mathematics

"People with scientific and engineering backgrounds are looking at the 3 WTC collapses, and what they see is very definite evidence of explosive demolition, as opposed to a "natural" catastrophe."

Jerry Lobdill

B.S.Ch.E., Physicist/Chemical Engineer

"All the eyewitness testimony and video evidence supports only controlled demolition as the cause of destruction for all 3 WTC buildings."

Robert Podolsky

M.S., Physicist/Engineer

"All 3 WTC buildings fell way faster than they would have had there been any resistance from the lower part of the building."

Niels Harrit

Ph.D., Chemistry

"A new investigation is needed that includes looking for remaining explosives and thermitic materials in the WTC dust."

Robert Kim Ireland

B.S.Ch.E., Chemical Engineer

"3 buildings collapsed on 9/11 but there were only 2 planes, that means the third building, WTC 7, had to collapse for some other reason."

Jason Cheshire

B.S.Ch.E., Chemical Engineer/Metallurgist

"1400º hot spots at the WTC for over a week indicates that there was something very hot going on below the surface."

Kathy McGrade

B.S., Materials Engineering

"In an office fire, you cannot generate enough heat to melt steel."

Mark Basile

B.S.Ch.E., 25 Years in Materials Analysis

"I’ve independently seen thermitic activity within 2 separate independent samples of world trade center dust. All of the characteristics of the micro-spheres tell me that thermite was used in melting those steel beams."

Adam Parrott

B.S.Ch.E., Chemical Engineering

"When the USGS collected samples of the World Trade Center dust, they found the presence of these microspheres of iron in all of the samples. The USGS does not have a valid explanation for the presence of these iron microspheres."

Jeffrey Farrer

Ph.D., Materials Science Engineer / M.S. Physics

"Our conclusions were that the red/gray chips were some form of thermite or nano thermite. The finding of aluminum in the steel samples also supports the theory that thermite was used to melt the steel."

Steven Jones

Ph,D., Physicist, Former Brigham Young Univ. Professor

"Molten metal in the basements of all three buildings. What is this molten metal? Direct evidence of the use of thermite."

David Gregg

Ph.D., Chemical Engineer 30 years at Livermore Laboratories

"The only way that’s known that a carbonaceous material can cause steel, or iron oxide to turn into a molten metal is in a blast furnace. And that’s very different than what we had."

Kevin Ryan

B.S. Chemistry, Former Mgr. Underwriters Laboratories

"Thermite -if it was present at the World Trade Center, and created this molten metal that so many witnesses and photographic evidence shows would also explain potentially the fact that fires could not be put out at Ground Zero."

Bob Bowman

Ph.D., Lt. Col. USAF Ret.

"When I saw the Twin towers fall down I knew this could not happen, those airplanes and those fires could not cause the buildings to come down the way they did."

Lynn Margulis

Ph.D, Professor, University of MA

"The WTC buildings came down because they were very carefully controlled demolitions with high-explosives that had to be planted many weeks, if not months, in advance."

Steve Luce

Former US Army Combat Engineer

"The ejection of building materials out of the sides of the buildings, and the manner and speed at which they fell, exhibited all the signs of controlled demolition."

Les Young

High-Rise Architect

"Building 7 had not been hit by a plane. The fact that it fell in on itself in just six seconds in a classic controlled-demolition fashion left no doubt in my mind that something was wrong."

Steve Barasch

High-Rise Architect

"Buildings just don’t behave like that. If floors fall, they tend to fall and are braced by the floor directly beneath it. And there is some delay there."

Ronald Brookman

S.E. Structural Engineer

"As a structural engineer I don't believe that the failure of one column would normally bring down an entire building in the way we saw World Trade Center 7 come down because of redundancy, because of all the other columns in the building that were not affected."

Joel Miller

Architect

"It appears to me that there’s compelling evidence that all three of the world trade center buildings were brought down by controlled demolition. There is not only video evidence, but there is physical evidence as well."

Erik Lawyer

Firefighter

"There were all kinds of firefighters and civilians that were reporting explosions. Just the fact that there were explosions means they need to be investigated."

Michael Donly

P.E. 14-year Structural Engineer

"There’s not enough time for the building to collapse in the way NIST tells us it collapsed."

Jonathan Smolens

S.E. Structural Engineer

"A building cannot do free fall with a huge steel structural system in place to support it without being blown up."

David Topete

S.E. Structural Engineer

"For World Trade Center 7 to collapse straight down upon itself as the video indicates, as everything that we've witnessed, the supports at the center essentially all had to be taken out at once."

Casey Pfeiffer

S.E. Structural Engineer

"Even if a floor were to collapse it still wouldn’t be able to collapse all of the connections simultaneously at the rate that it did without secondary explosions."

Harry Robinson III

FAIA, Architect

"The destruction was too symmetrical to have been eccentrically generated. The destruction was symmetrically initiated to cause the buildings to come apart as they did."

William Cundiff

P.E., Structural Engineer

"The speed at which the buildings fell should be the most obvious and least technical indication that explosives were used. Most engineers as well as non-technical people should be able to grasp this."

Kevin Kelly

FAIA, Architect

"The presentation made by Architects & Engineers for 9/11 Truth at the AIA Convention in San Francisco made a sufficient case that a new investigation into the destruction of the 3 skyscrapers on 9/11/01 would be worthwhile."

Pedro Buccellato

High-Rise Architect

"I believe that all the evidence made available by AE911Truth proves beyond any doubt that explosives were used to bring down the towers as many people concluded from the outset, simply from visual evidence and knowledge of basic physics."
