Richard Dolan investigates the events of 9/11 to discern discrepancies in the official narratives, bringing us closer to uncovering what really transpired on that fateful day. Although we still don’t have a definitive answer, some of the alternative narratives posed offer plausible solutions. We explore the science of controlled demolition and how it compares to the World Trade Center buildings’ collapse. Plus, we look at related events, prior to and during the attacks, which suggest that the ties behind these events stretch even deeper. This presentation by Richard Dolan was originally webcast September 19, 2017.
