9/11.. 3 buildings collapsed like a stack of pancakes into their own footprint at freefall speed?
3,000 architects, engineers, firefighters, and demolitions experts have said there is no way those buildings collapsed in that way because of airplanes.
Please research building 7 before responding to this post. Most people don't even know it fell. Not only did it fall, it was obviously a controlled demolition according to experts. Go look at a you tube video on building 7 first, please, and discuss.
