On this twenty-first anniversary edition of 9/11 Free Fall, Drew DePalma and AE911Truth board member Bill Brinnier talk with host Andy Steele about the impact the cover-up of 9/11 has had on their lives. DePalma's mother, Jean, and Brinnier's best friend, Frank De Martini, were both murdered in the horrific demolition of the North Tower on that tragic day 21 years ago.
