Most DB Cooper references I've read consider him to be some cross between a folk-hero and lovable-rogue due to the audacity of his crime, lack of harm to civilians, and the idea that he might have actually gotten away with it.
But fascinating to read the Wikipedia entry and realize that DB Cooper, and the no less than 15 copycat "parachute hijackings" he inspired in the same year, created a watershed moment in Airport Security that accelerated our steady march to today's over bearing TSA:
"In all, 15 hijackings similar to Cooper's—all unsuccessful—were attempted in 1972.[130] With the advent of universal luggage searches in 1973 (see Airport security) the general incidence of hijackings dropped precipitously.[131]"
