November 24th is the anniversary of the most daring bank robbery ever attempted.
And possibly to succeed.
In 1971, D.B. Cooper (real name Dan Cooper) leaped from a Northwest Airlines Boeing 727 with two parachutes and $200,000 in ransom into a stormy southwestern Washington state sky, a temperature of 7 below and a clip-on tie.
The tie was found. His fate remains unknown.
Despite hundreds of leads through the years, no conclusive evidence has surfaced regarding Cooper's true identity or whereabouts.
The bulk of the money has never been recovered, although in 1980, a kid found $5,880 in decaying $20 bills on the banks of the Columbia River which were linked to the ransom money.
Several theories offer competing explanations of what happened but the FBI believes DB did not survive.
Personally I wonder if he ever jumped out. Maybe he just lowered the stairs and hid somewhere else on the plane?
See the original CBS news story on the jump.
PS - Today's also the anniversary of Jack Ruby shooting Lee Harvey Oswald.
