Since it happened in 1971 I have been fascinated with the case of D.B. Cooper. He hijacked a plane and demanded $200,000 or he would blow up the plane and its passengers. He escaped that night by jumping out the back of the Boeing 727 holding his money, parachuting his way into folklore and a manhunt which continues to this day.
Television producer Tom Colbert assembled an impressive cold case team and went to work. The efforts lead to evidence the FBI now has in its possession. Colbert also believes he "knows" who D.B. Cooper really is and that "Cooper" is alive today.
The book, "The Last Master Outlaw" is a good read. The story is a fascinating listen.
