DB Cooper most likely fell to his death from the plane he jumped from.
I loved that show.
The Cooper story was actually made into a show, in the form of a bad TV movie. (The actual name used by the sky jacker was simply "Dan Cooper," but somehow the press used "D.B.")
This ass-hat, for some odd reason a folk hero to some, started a sky-jacking fad, with every other flight getting high-jacked to Cuba. Thanks to him, we now have to pass through cattle chutes and metal detectors every time we board an airplane.
The good news is, he's almost certainly dead.
