I know this isn't TV, but Sarah, have you seen this? I got it from Book Riot's Today in Books newsletter.
Publisher Claims To Know 1971 Plane Hijacker’s Identity
There’s only one still unsolved skyjacking in U.S. history: The identity of “D.B. Cooper” the man who hijacked a 1971 flight and parachuted out with $200,000. Carl Laurin’s publishing firm announced they cracked the case with a “memoir detailing the confessions of a longtime friend who supposedly committed the crime: Walter R. Reca, a former military paratrooper and intelligence operative.” (If reading about when plane hijackings were routine is your thing, you’ll probably be interested in The Skies Belong to Us: Love and Terror in the Golden Age of Hijacking by Brendan I. Koerner)
