If you have 15 minutes to invest in learning what happened, have a look at this:
Ultra short summary: Putting aside the twin towers themselves, there was a third building, 47 stories high, called Building 7, that also imploded on 9/11 [in seven seconds]. No plane hit that building, everyone agrees. So why did it collapse?
NIST, the agency paid 16 million dollars by the US Govt to find out what happened on 9/11, says the building collapsed because of fire, caused by burning office furniture.
Over 2,500 architects and engineers beg to disagree, and in fact have an online petition going round to investigate the whole ugly business independently.
The video shows many buildings collapsing in the exact same manner the twin towers and Building 7 did. It happens routinely all around the world. It’s called “planned demolition.” It takes many months to prepare, and it involves putting explosives inside the building and blowing it up. Experts who saw the 9/11 videos say that what happened, the flattening like a pancake, the incredible speed of the collapse, could only happen if there was a planned demolition, planned months in advance.
No fire could ever do it. Modern buildings have caught fire, at much hotter heat, and they did not collapse. It’s like saying Hiroshima happened because somebody lit a match. Plenty of clips showing those fires, too.
I am totally convinced. These are not kooks by any definition, but serious people, such as the manager of Underwriter Laboratories, technical experts with degrees, mechanical engineers, structural engineers, high rise architects, materials scientists, chemists, metallurgists, physicists, explosive experts, demolitions experts, fire protection experts, winners of science medals in their fields, and on and on.
There are many more suspicious happenings that the video points out. Have a watch.
