The offence on the face of it was a simple one, but the mystery surrounding its aftermath has passed into legend. On 24 November 1971, a man going by the name of D. ('Dan') B. Cooper hijacked a Boeing 727 on a domestic flight and demanded $200,000 from its owners, Northwest Orient. Confident they would catch the hijacker, the company agreed to pay the cash in exchange for their passengers.
But the hijacker had other plans. After the aircraft had taken off again, minus its passengers and with D. B. Cooper $200,000 richer, he strapped himself to a parachute and jumped out into the cold night. He was never seen or heard of again, so if he survived the jump, it had been the perfect crime. If not, of course, he had been the perfect idiot.
Either way, D. B. Cooper became an instant celebrity among the tie-dyed, hash-smoking hippies of the early 1970s, when hijacking had rather more of a romantic/revolutionary feel about it than it does today when terrorists are suspected at every turn. Despite one of the biggest manhunts in American history, including amateur investigations, books, TV documentaries and films, nothing more is known about D. B. Cooper today than was known on the day of his daring, airborne stunt.
So let's look at the events in a bit more detail. At 4 p.m. on that particular day in 1971 the fourth Thursday in November, Thanksgiving Eve a soberly dressed businessman approached the counter of the Northwest Orient Airline at Portland International Airport and bought a one-way ticket to Seattle for $20.
The businessman, who gave his name as D. B. Cooper, was allocated seat 18C on Flight 305, which left on time at 4.35 p.m., climbing into the cold, rainy night with thirty-seven passengers and five flight crew on board.
