The FBI is re-opening the DB Cooper case to try and figure out if anybody is willing to talk after 30+ years of mystery. 

For those too young to remember, a man known as Dan Cooper hijacked a plane in the Pacific Northwest (U.S.A.) in 1971 and demanded $200,000 cash (a large fortune in those days) and a parachute or the plane would be blown up. The ransom was paid, the plane flew towards Mexico and Mr. Cooper bailed out - possibly somewhere near the Oregon/Washington border.

He (and the money) vanished without a trace, although a kid found a few thousand in tattered $20 bills in the woods several years later that presumably came from the ransom loot. Whether he lived or died after the jump has long been the subject of speculation. 

Mr. Cooper - if you're out there,  hope you're doing well; and a toast - "You took the money and ran". Cheers mate.
