60 Aerospace Engineers Call for New 9/11 Investigation
— Dwain Deets
As the number of verified architect and engineer petitioners at AE911Truth passes 1,000, the number describing themselves as aerospace engineers, or as engineers who have contributed professionally to the aerospace field, exceed sixty. These sixty-plus engineers were motivated to place their names on the public record as a matter of professional and social responsibility. While the skills necessary to conduct professional forensic analysis of destroyed buildings is largely distinct from those experienced in aerospace engineering, the basic physical laws involved in an analysis of the speed, symmetry, and energy input/output balance of the World Trade Center's destruction involve only high school physics and chemistry, some lookups regarding the energy necessary to crush concrete, and basic arithmetic.
Here is a listing of these sixty-plus aerospace engineers, together with brief bios and their statements made at the time they signed: The engineers are listed alphabetically, grouped with those having full careers in aerospace listed first, and those with less than 30 years in aerospace listed second.
Engineers with Full Careers in Aerospace
Phil R. Bales, Aerospace Reliability and Life-Cycle Engineer. Employers have included major commercial engine companies, Teledyne CAE, Raytheon, and US Navy Civil Service.
"I was acutely aware of Engineering Cost Analysis and Life Cycle Cost Analysis, with many post graduate courses in these disciplines. My career was heavily biased toward statistical analysis and Warranty Cost Forecasting, requiring me to consider all possibilities, emphasizing the likelihood that the less likely events should be considered less heavily.
"Perhaps, this is why I was extremely reluctant to even consider the possibility that 9/11 could have been a staged event. 'What is the chance that our own government could pull that off and get away with it?' I pondered. When I was confronted with the facts, and I considered the reality that the temperatures of jet fuel combustion do not support the suggested failure modes posed by the government's official report, I was forced into a paradigm shift. This reality has changed my entire perspective on the groups that I had previously dismissed as emotional, uneducated fools. I was wrong and I am grateful to the 9/11 Truthers for holding me accountable for the Truth! Now, I too am a 9/11 Truther.
"The facts about the collapse of three WTC buildings on 9/11/2001 just do not support the theory posed by the PBS Report, or the US Government's publication. There must be further explanation to satisfy my hunger for the truth about the horrible realities of the WTC and Pentagon murders.
"As an engineer, as a patriot, as citizen of the United States of America, I demand that the government which is accountable to its citizens appoint an independent commission to investigate and report on the Truth of 9/11/2001."
Dr. Robert M. Bowman, Lt. Col., USAF, ret; Exec VP, Millennium III Corp; Vice-Pres, Space Communications Co; Director of Advanced Space Programs Development, US Space Division (USAF); 101 combat missions F4, Vietnam; Head of Aero. Eng. Dept & Asst Dean, AF Inst of Tech, WPAFB.
"The official explanation in the NIST report violates the laws of physics. It is physically impossible for a building (or anything else) to fall at near-free-fall speed and do work (smashing steel and concrete) on the way down. An external energy input (like explosives) is absolutely essential. In addition, for the top of one of the towers to tip about 30 degrees and NOT continue tipping and falling off violates the law of conservation of angular momentum. The symmetrical collapse of building 7 due to highly asymmetrical damage is also unbelievable. We have not yet been told the truth. If the government has nothing to hide, why continue to hide everything? Why not a new and truly independent investigation?"
Dr. Alvin M. Bloom, Engineering consultant. BS, MS, PhD in Aerospace Engineering from University of Texas at Austin 1967
"Building collapses (straight down) at free fall speed could only be caused by a controlled demolition."
Paul Browning, M.S. 35 years engineering experience with a NASA contractor, Bell Labs, Bellcore, AT&T Labs and Cingular/AT&T Mobility (12 years Engineering Management)
"The only steel framed skyscrapers to have ever collapsed as a result of a fire were WTC 1, 2, and 7. These buildings were built to withstand the impact of a fully loaded Boeing 707, an aircraft about the same size and weight as the aircraft that hit them on 9/11.
"Temperatures produced by the fires simply did not reach those required to have a significant impact on the building's structural integrity. Firemen 2 floors beneath the impact area in one building radioed out that the fire was controllable. Obviously he was not confronting a temperature of 2000 degrees only two stories above him. Pictures showed survivors of the impact standing in the hole made by the aircraft. These people wouldn't have been there under the kind of conditions assumed by the official story.
"Fireman recalled hearing a series of secondary explosions exactly like those that would have been used to cause a controlled demolition and that the collapses looked exactly like that's what happened.
"WTC 7 was hit by nothing and yet collapsed in the same way as the towers. Molten metal containing sulfur, indicating thermate, remained underneath all three buildings for weeks after 9/11. The structural steel debris was carted away as soon as possible without inspection. Taking pictures of ground zero or even stopping to look at it was made a criminal offense.
"The impact of the aircraft and the resulting fires could not possibly have caused the twin towers to collapse and saying that the collapse of WTC 7 was due to the impacts is simply absurd."
Dr. David Chen, PhD in EE from the University of Illinois at Urbana-Champaign. Worked at various aerospace companies doing artificial intelligence work, networked, real-time systems, and network security. Currently an Associate Technical Fellow at the Boeing Anaheim, California site.
"NIST & the US Congress should be ashamed of the poor investigation.
"Thanks to the architects & engineers of this site for carrying the torch for truth."
Malcolm Davis, Degree in Aerospace Engineering from the University of Texas (Austin) in 1961.
"It is absurd to think that WTC 7 collapsed as a result of the events, as generally promoted, surrounding September 11.
"It is indeed depressing to observe that a large number of United States citizens didn't even know that WTC 7 even existed."
Joseph L. DeClue, Graduate MIT Class 1951, Retired Pres. Database Multitech, Designed analog and digital circuits. Eventually managed as Chief Engineer and V.P. Engineering of several companies and founded Database Multitech as a design and service company.
"The Government's politically-correct explanation is not credible. It seems highly likely that our government must have had some part or at least been aware of the pending attack. Also the lack of response by the Air Force was not credible."
Dwain A. Deets, Former Aerospace Research Engineer. While at NASA Dryden Flight Research Center, held positions of Chief, Research Engineering Division, Director for Aeronautical Projects, and Flight Research Program Manager.
"The many visual images (massive structural members being hurled horizontally, huge pyroclastic clouds, etc.) leave no doubt in my mind explosives were involved."
Thomas James Dolan, 45 years as mechanical/project engineer on Apollo manned lunar landing program, X-15, B-70, T-39, aircraft accident investigator (USC & FAA certified), Boeing 767, Space Shuttle, Navstar Global Positioning System and the Space Station.
"I have seen on TV commercial buildings collapse under controlled demolition prior to 911. I have been told that no certified US demolition companies will comment officially on 911. I personally saw and heard in real time 2 firemen (one dirty and exhausted, seated outside on a low brick garden wall) and another just reporting for action - nice and clean. Both were looking at Building 7 in the near background (1 block?) away and to the question for the exhausted one by the fresh one regarding its status the exhausted one looked at his watch and said as clearly as I can remember, 'Its going down about 4:30! I didn't think too much about it at the time but now I think about it a lot whenever 911 comes up!'"
Larry Erickson, Retired NASA engineer (33 years). Performed research in the fields of structural dynamics, aerodynamics, aeroelasticity and flutter.
"Serious technical investigations by experts seem to be lacking from the official explanations."
Edmond (Monty) John Forbes, In 1981 joined MITRE Corp, Bedford MA as Lead Sys Engineer for airborne Wide Body Presidential assets. This extended to Special Service classified systems in both fixed wing & rotary wing platforms until retirement in 2004.
"True, both WTC 1 & 2, North & South structures were impacted by commercial "767's" killing innocent passengers, crew & hijackers along with occupants in the building floors at point of impact. The devastation and human loss beyond the impact site was due to other influences because of the proven design and features of the Towers.
"The temperatures in the impact areas due to burning Jet-A fuel and the office furnishings and business tools could NOT rise to the level of 3000-4000 deg. F necessary to deform and fail structural steel joints and the total collapse of the structures.
"Such 'failure' could only be caused by man-made features of pyro-technical assets pre-placed by 'outsiders.' Look at the destruction of WTC 7. No aircraft or heavy debris collateral from the Towers struck that building.
"All destruction was in the classical method of building REMOVAL to make way for new assets."
Marc Graziani, Engineer and engineering manager for Sperry Utah and Univac for many years, primarily in the aerospace industry.
"There is no degree required for simple common sense, if all structures fell as these structures did then why do we spend millions of dollars each year paying demolition experts to demolish structures for minimal collateral damage? This is not a perfect world, no structure of this magnitude could weaken perfectly and collapse in on themselves."
Dr. Jay Kappraff, Assoc. Professor of Mathematics. Chemical engineer with Dupont 1960-1961, Aerospace Engineer with NADA 1963-1965, Ph.D. in mathematics from NYU Courant Inst. specializing in Plasma Physics, Assoc. Prof of Math. at New Jersey Inst. of Technology 1974-present.
