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:

Paul I do this for a living and have for forty years in fact I know exactly how those buildings were designed and built. I also have a complete set of drawings and all structural design criteria along with all data on the testing done on those buildings so yea I do know a thing or two about it
Airplanes responsible for downing of first two towers. Building 7 was a controlled demolition with sensitive information inside the building.
pLEASE TELL ME HOW THE PLANE ENDED UP IN THE BUILDING
BFS
There is no way that the jet fuel/ kerosene and office supplies we’re able to burn hot enough to have any effect on structural steel. Further more there have been many examples of skyscrapers totally burnt in fires way more devastating that stood as a burnt out shell after fire was out. How do you explain the thermite found in the samples of the rubble? Why was the steel shipped overseas on barges before it could be inspected? Also extraordinarily good fortune that Mr. Silverstein his son his daughter and his publicist , whom were all there each and every day of the six weeks leading up to this event eating breakfast at 8 am sharp, all managed to either be late or not show for various other reasons!! I could go on because the suspicion doesn’t stop there.
I already knew that now the only question is what happened to the twin towers for real. A plane did not hit the Pentigon please notice no other video was ever released, WHY ? because it wasn’t a plane. The plane they say went down in the field ? same as the Pentigon where was the engines where were the bodies where was ANY plane wreckage ????????
they
ALL
WERE
You do what for a living?? What makes you think you know more about what happened here than the structural engineer from MIT that have spoke out publicly against the 911 commission theory??
i studied demo.
even worked on a few.
a building ONLY falls that way from THE INSIDE.and i am a certified welder.
the temps were insufficient to burn the alloys used then.by about 500
only an$#%&!@*would believe this post.
