The FBI recently took new interest in the epic 1971 Seattle hijacking by a man who called himself D.B. Cooper. The perp took his ransom money and a parachute and exited a Northwest Airlines 727 by way of the rear stairs — while it was in flight.
The agent who has taken over the investigation has discovered an obscure French comic book hero named Dan Cooper, who was a paratrooper. And the agency has engaged amateur sleuths to examine evidence from the case using new technology.
It's an idea right out of the citizen-journalism movement.
