Dr.Docs' Take

Four and a half hours of cases that flat-out refuse to close, headlined by the man who jumped out of a plane with two hundred grand and melted into the rain. This is the long buffet, skyjackers, cold cases, the whole tray. My advice is snacks and a suspicious mind, in that order. Nobody solves anything across the entire runtime, and I promise you that is the appeal, not the flaw.

Mystery of the Disappearing Skyjacker In 1971, a man calling himself Dan Cooper hijacked a plane and requested $200,000. Cooper escapes with the money and is never seen again. Now with new evidence, experts hope to solve this heist. Dark Secrets of the CIA It's the Cold War's dirty little secret: a terrifying account of the CIA's efforts to expose unknowing members of the public to biological agents, hallucinogenic drugs and psychological techniques aimed at mastering the art of mind control.
