WTC 7 Evaluation is a two-year study by Dr. J Leroy Hulsey, Chair of UAF’s Civil and Environmental Engineering Department, and two Ph.D. research assistants. It is being crowd-funded through the nonprofit organization Architects & Engineers for 9/11 Truth.
I’m convinced that even the most rudimentary of models will show that the WTC 1, 2, and 7 collapses absolutely required controlled demolition to occur the way they did.
As time goes on, and computing power is more available, it will be easy to prove conclusively, that buildings generally don’t fall through themselves.
The Features of Controlled Demolition versus Fire-Induced Failure
|CONTROLLED DEMOLITION||FIRE-INDUCED FAILURE|
|The collapse is total, leaving virtually no parts of the building standing||The collapse is usually partial (always partial in the case of steel-framed buildings), leaving much of the building standing|
|The onset of collapse is always sudden.||The onset of collapse is gradual, with visible building deformations appearing prior to the actual collapse|
|The collapse lasts a matter of seconds||The collapse takes place over many minutes or hours.|
|The collapse typically starts at the base of the building, though they can be engineered as top-down also.||The collapse occurs randomly anywhere in the building|
|The building descends symmetrically through what was the path of greatest resistance, though asymmetrical collapses are sometimes engineered on purpose||Collapse is always asymmetrical|
|The building typically descends to the ground at near free-fall acceleration||The descent of falling portions of the building is slowed or stopped by the lower sections of the building|
|“Demolition squibs” (isolated explosive ejections) are visible outside the main zone of destruction.||Explosions only occur at the location of fires, if at all|
|Concrete and other materials are sometimes pulverized, resulting in fie dust clouds.||Concrete and other materials are not pulverized. Most of the building’s remaining structure is left intact or in large sections.|
|The building’s steel structure is totally or mostly dismembered||The building’s steel structure is left mostly intact, even if heavily damaged.|
If the destruction of WTC 1, WTC 2, and WTC 7 were caused by fire, this would make them the first steel framed high-rise buildings in history to suffer total fire-induced collapse (combined with structural damage from the airplane impacts in the case of WTC 1 and WTC 2). They would also be the first fire-induced collapses to exhibit nearly all of the features of controlled demolition and none of the features of fire-induced collapsehttp://cafr1.com/Beyond-Misinformation-2015.pdf
