WTC 7 was the third building that “collapsed” on 9/11. This “collapse”, which took place at nearly free-fall speed and looks exactly like a controlled demolition, was supposedly caused by fires started from debri of the Twin Towers “collapse”. It is completely omitted from the 9/11 Commission Report, not mentioned once in the 500+ pages.
9/11 was an inside job. Ask questions. Do your own research and come to your own conclusions.
