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:

Tim Leach, Leslie e Robertson was the lead designer of the twin towers and he designed them to withstand the impact of a Boeing 707. It kills me you people get on here running your mouth not knowing any facts.
Tammy this is a picture of the steel floor trusses that was taken on the 82 floor of the north tower during a fireproofing inspection as you can see the structural members are not that big. In fact all floors in those buildings had to have reinforcing done just to support the file cabinets in the offices.
All three buildings were brought down by explosives.
Greg…how do you type so well wearing that straight jacket…
Wyatt Blackwood all you are doing is making a fool out of your self. Yes the plane it the tower and it withstood the impact. So it did not collapse because of the plane.
You need to school your self with the impact of fire on metal even if it has fire retardant jet fuel Burns hotter than any other. Please get your conspiracy theory out of this page
You are all ‘conspiracy theorist’ nut jobs.
Tim Leach, you don’t and can’t land at 500 mph, well ok, once. Normal landing speed is 140 to 190 mph. And John f Ferguson, I have a very talented tounge!
it was all controlled demo!
you have alreadfy seen the proof.
you just don’t know what you saw!
Don’t be ignorant. Question everything you are told. Many ppl who were in the buildings said multiple exclusions went off on the basement… this was inside job all the way. If you understand demolition then you will know explosion strategically placed took this buildings down. Also of a airplane hit tje Pentagon where is tje video.? Please ignore tje facts and keep believing the lie
Listen people. This was not an inside job. Osama bin Laden got 19 kids to do you hijack planes flying into the World Trade Center and the Pentagon 2799 people died. No conspiracy theory no nothing old news get over it
