This is a collection of interviews conducted by the organization "Architects and Engineers for 9/11 Truth" which tries to make the population aware that there are more than 1900 architects and engineer which do not believe the official government story about 9/11 and demand a new independant investigation on what really happened on that day :

(In this article you will find multiple references to World Trade Center 7 (WTC7), in case you never heard of this third high-rise building which collapsed on the afternoon of September 11th 2001 you might want to check out video footage of this collapse. The footage is available in the linked article in the Knowledge Base - it is the first embedded video in the article)

Dr. Bob Bowman, Lt. Col.

Bob Bowman is a retired Lieutenant Colonel from the US Air Force. He has three degrees in engineering and a Ph.D. in aeronautics and nuclear engineering and worked on finite element analysis. During his life he taught at 5 universities. When watching the collapse of the World Trade Center he immediately knew that what he saw violated the laws of physics - particularly the collapse of WTC7 :

Casey Pfeiffer, Structural Engineer

Casey Pfeiffer has a bachelor of science degree in civil engineering. He has been working as a structural engineer for 15 years. In his job he specialized in the construction of industrial steel frame buildings. After seeing videos of the collapse of the World Trade Center Casey was confused as what he was seeing did not fit with what he knew about buildings from his education. The fact that the segment of WTC1 above the impact location of the plane disintegrated to about half its original size at the beginning of the collapse made absolutely no sense to him because this part of the building was not damaged by the plane :

Ron Brookman, Structural Engineer

Ron Brookman got his masters degree in structural engineering in 1986 and is a licenced structural engineer from California. He worked on designing commercial office buildings and manifacturing facitities for the last 24 years. After watching videos of the collapse of WTC7 he immediately concluded that this had to be a controlled demolition, since no plane ever hit that building. He also found it a bit alarming to see debris shooting out at 80mph in all directions during the collapses of WTC 1&2. He wrote a scientific paper on his observations of the collapses and came to the conclusion that the National Institute of Standards and Technology never did a proper evaluation of the available evidence :

Kamal Obeid , Civil and Structural Engineer

Kamal Obeid has a masters degree in civil and structural engineering. He has been a practicing engineer for the 30 years and a licenced structural engineer for the last 25 years. During his worklife he had to look at collapses of buildings to determine their cause. After analyzing the collapse of World Trade Center 7 he is convinced that this third building to collapse on 9/11 was brought down by a controlled demolition : 

Michael Donly , Structural Engineer

Michael Donly is a structural engineer with 14 years of experience in designing steel-frame fire-proof buildings. When watching the collapse of the World Trade Center Michael felt his judgement as an engineer called into question because he never expected to towers to collapse. After starting his own research into the collapse at free-fall speed he realized something was very wrong with the official story, especially with regard to WTC7 :

Stephen Dusterwald, Structural Engineer

Stephen Dusterwald is a licenced structural engineer with 37 years of experience. From designing multiple commercial steel-frame buildings he is very familiar with the way structural failures of overloaded beams happen and that buildings are designed in a way to give the occupants enough warning time due to visible deformation of the building structure. From analyzing the speed of collapse Stephen sees clear inconsistencies within the models by NIST because the collapse of WTC7 happened in free fall for the first 100 feet which shows that there was absolutely no resistance - This is impossible in a natural graviational collapse but could be explained by the use of explosives :

Kathy McGrade, Metallurgical Engineer

Kathy McGrade got her bachelor degree in metallurgical engineering in 1979. She got interested in 9/11 when being asked by a friend if office fires can melt steel. The more Kathy looked into the available evidence the more horrified she got. She states in the interview that you don't have to be a scientist or an engineer to figure out something is fishy with the official story. All you need to do is look at the videos and the obvious evidence. For Kathy the smoking gun is the symmetry of the collapses because you can not have a symmetric collapse with asymmetric damage caused by the planes :

Tony Szamboti, Mechanical Engineer

Tony Szamboti is a mechanical engineer with over 20 years of experience in the aerospace industry designing structures for aircrafts and spacecrafts. After 4 years of intense investigation and writing several scientific papers on the subject Tony comes to the conclusion that what we have been told be government and media about 9/11 is false. In his recent paper he lists 24 points where the National Institute of Standards and Technology investigation is false and he suggests to have NIST investigated for coming to false conclusions :

Ed Munyak, Fire Protection Engineer

Ed Munyak has worked as a licenced fire protection engineer for the last 24 years. He worked for government as well as large insurance companies as a consultant for fire safety. What Ed witnessed happening on 9/11 was totally contrary to anything he ever experienced in his carrier and in his opinion the events defy the fundamentals of mechanics and physics. To solve the inconsistencies within his own mind he began a study in fire of high-rise buildings and found out that nothing comparable ever happened in the past even though there were fires a lot larger than the fires on 9/11 :

Jerry Lobdall , Chemical Engineer , Physicist

Jerry Lobdall is a retired physicist and chemical engineer. He has a bachelor of science degree and has extensive course work in mathematics and physics from the University of Austin. He has over 30 years of experience in various government projects. After reading scientific papers on 9/11 he became interested in the evidence found in the World Trade Center dust which might be proof of a controlled demolition :

Richard Humenn P.E. , WTC Chief Electrical Design Engineer

Richard Humenn is a retired professional electrical engineer. He received a bachelor of electrical engineering in 1954. He worked as principal chief electrical engineer for the World Trade Center complex. During his worklife he was trained in controlled demolition. After looking into the scientific evidence presented by Architects and Engineers for 9/11 Richard is convinced that the official story can not be true :

Robert Podolski, Physicist & Engineer

Robert has a masters degree in theoretical physics. He worked for 10 years as a physicist, engineer and systems analyst for government and industry. Robert became interested in inconsistencies regarding 9/11 when he looked up the burning temperature of jet fuel which does not fit the official story that fire from jet fuel caused steel beams to melt. He also did a conservative energy calculation on how much energy would be required to destroy the building the way it was destroyed and compared it to the energy stored in the building. His result : The energy in the building was only 1 percent of the energy required for the destruction. So were did the other 99% of the energy come from ?

David Topete, Civil and Structural Engineer

David Topete has a master of science degree in Civil Engineering and is a licenced structural engineer. After David saw videos of the collapse of WTC7 in the afternoon of 9/11 he became suspicious and felt compelled to join Architects and Engineers of 9/11 Truth. He has severe doubts regarding the official report especially with regard to WTC7 :

Due to the large amount of interviews, several interviews were linked separately :

• Tom Sullivan & Les Young - Demolition Expert & Architect on 9/11
• Jeff Farrer : Material science-based research on 9/11
• Mark Basile : Chemical analysis on 9/11

The organization Architects and Engineers for 9/11 Truth used the interviews presented here in their documentary "Explosive Evidence - Experts speak out". This documentary also shows a lot of scientific evidence and is available in the Resource section
