There is more scientific proof suggesting Building 7 was destroyed by controlled demolition than the resulting fires from the debris.
A new scientific study found the official story surrounding 9/11 was not compatible with the laws of physics. Several studies have already reached similar conclusions. However, this is the 1st to provide the long-awaited definitive answers.
The new study conducted at the University of Alaska Fairbanks took things one step further – we now know with a high degree of scientific accuracy that the official NIST explanation of how the World Trade Center 7 building collapsed is not only suspect, it’s 100% false, according to the findings of this academic study.
This study replicated and remodeled every factor relating to that infamous day involving building 7. Complete study results and the undeniable scientific evidence indicating Building 7 was a deliberate job on the next page:

Corey Salvadras -my source Popular Mechanics: WTC & WTC 7 the structural integrity was destroyed by intense fire as well as the damage inflicted by the planes.
Yes Jet fuel burns at 800 to 1500 F, steel melts 2,750 F. What you haven’t captured is steel loses 50% of its strength at 1,100F as per Senior Engineer Farid Alfawak-hiri of the American Institute of Steel Construction. And at 1,800 it is probably at less 10%. NIST also believes that a great deal of the spray-on fireproofing insulation was likely knocked off the steel beams that were in the path of the crashing jets, leaving the metal more vulnerable to the heat. And FYI the jet fuel wasn’t the only thing burning notes Forman Williams, a professor of engineering at the University of CA & one of the seven structural engineers and fire experts: he says while the jet fuel was the catalyst for WTC fires the insulting inferno was intensified by the combustion of material in the buildings. The jet fuel fire burned for apx 10 minutes the heat transfer was responsible for eventually brought them down.
.. no building designed to collapse down on themselves. I’m assuming your saying the building pancake design isn’t true. Please provide your sourse. The source that proves the pancake theory is Wikipedia states towers designed “tube in tube” going into one another some Architects refer to as pancake and a whole lot of details feel free to read and the NIST mathematics shown pancake collapse as plausible.
I Never seen source stating building designed to take impact by plane. Site your source. for the record I have family & friends that are Architects and Engineers.
Oh, cut the$#%&!@*
BS
It was Elvis in the third plane.
They all were demo-ed….The twin towers especially. They were capable of sustaining a direct hit from planes much larger.
No it wasnt
I can melt steel with propane and air. Steels properties weaken with heat . Even if you don’t melt the steel, heating it weakens it.
Youre an idiot.
You’re fucking stupid.
and the world is flat
