There happened to be another skyjacking 4 months later...

Richard McCoy Jr.

On April 7, 1972, four months after D. B. Cooper's hijacking, McCoy boarded United Airlines flight 855 during a stopover in Denver, Colorado. The aircraft was a Boeing 727 with aft stairs, the same equipment used in the Cooper incident, which McCoy used to escape after giving the crew similar instructions as Dan Cooper had. McCoy was carrying a novelty grenade and an empty pistol.

He was successful in the jump, but was caught a couple days later....
