D. B. Cooper - Unidentified man, who hijacked a Boeing 727 in 1971. Parachuted into the night with $200,000 ransom from the plane. Never been found or conclusively identified.

Tommy was reported to be incredibly rich. $200k isn't enough to be considered incredibly rich, especially not in Hollywood.

I found out who he was too. He also recently used the alias "Russ Nightlife" before being arrested by his maid.

There was another documentary that says he fought Bigfoot while a bunch of shirtless guys went jogging.

One of the stewardesses was so traumatized she spent a decade as a nun...doesn't sound like she was rolling in money either...

He asked for four, two main and two backup. Of those one backup was non-functioning and the other was supposedly possibly by him to carry the money.

He asked for two sets specifically to imply a hostage might be jumping with him, to negate the option of parachute tampering.

Then the corpse would have been located. A human body falling from a height doesn't drill into the ground. Also, the parachute would have been detected.
