On this follow-up special episode of 9/11 Free Fall, AE911Truth CEO Roland Angle and Director of Strategy Ted Walter join host Andy Steele to dissect the multiple conflicting theories of how fire caused the total destruction of World Trade Center Building 7 on September 11, 2001.

In their discussion, they juxtapose the engineering community’s astonishment at the collapse of Building 7 and its inability to arrive at a single theory 20 years after 9/11 against the absolute certainty among officials at the scene that Building 7 would come down later in the day.

How did the total, sudden, symmetrical, free-fall collapse of Building 7 go from being eminently predictable to eminently inexplicable? Angle, Walter, and Steele trace the troubling story of an engineering establishment that has refused for two decades to consider the most likely cause of Building 7’s destruction: controlled demolition.
