only a 10,000 foot elevation. The legend of D.B. Cooper was born. To this date, the Cooper skyjacking is the only case that is unresolved in the United States. Cooper was never found, nor was any evidence of the $200,000, and his parachute. Many believe Cooper could not survive a drop of such a great altitude, while others say the absence of any of the money, or any evidence of his death proves he survived. In any event, D.B. Cooper is a true American legend.
