On the afternoon of Thanksgiving Eve, November 24, 1971, a man identifying himself as Dan Cooper boarded Northwest Orient Flight 305 from Portland to Seattle. Shortly after takeoff, he revealed a bomb in his briefcase and demanded $200,000 and four parachutes, setting the stage for one of history’s most daring air piracy cases.
After the ransom was delivered in Seattle, Cooper released the passengers, refueled the aircraft, and in flight, opened the Boeing 727’s rear stairs and parachuted into a stormy, forested region—leaving behind only a clip-on tie, cigarette butts, and unanswered questions.
The Hijacking Unfolds
Flight 305 took off at 2:50 p.m. PST. Cooper, seated in the last row, handed a note to flight attendant Florence Schaffner. When she initially ignored it, he opened his attaché case to show what appeared to be sticks of dynamite wired to a battery. His calm yet firm threat—“Miss, you’d better look at that note. I have a bomb”—secured her compliance.
Demands and Negotiations
Cooper requested $200,000 in twenty-dollar bills, two sets of parachutes, and a fuel truck waiting in Seattle. During a three-hour holding pattern over Puget Sound, authorities assembled the ransom and parachutes as Cooper sipped bourbon and chatted casually with the crew, revealing surprising familiarity with the aircraft and terrain.
The Ransom Exchange
At Seattle-Tacoma Airport, Cooper allowed all 36 passengers and two crew members to disembark before the money and parachutes were brought aboard. He inspected the bundles—10,000 unmarked bills in a canvas knapsack—complained jokingly about the denomination, then ordered the plane refueled and a flight toward Mexico City via Reno and Yuma.
The Vanishing Jump
About five minutes after departing Seattle, the aft-stair indicator illuminated, and Cooper opened the Boeing 727’s rear stairs. In darkness, rain, and subzero temperatures at low altitude, he jumped into the Pacific Northwest’s rugged forests. The crew never saw him again, and no body was ever recovered.
Investigation and Clues
The FBI launched Operation NORJAK, interviewing over 800 suspects. Investigators recovered Cooper’s clip-on tie and several cigarette butts, but found no fingerprints or conclusive evidence. In 1980, a boy found $5,800 of the ransom scattered along the Columbia River, renewing interest but failing to solve the case.
Theories and Speculation
Did Cooper perish in the freezing wilderness? Did he survive and disappear silently? Over the decades, suspects have ranged from experienced skydivers to ex-military paratroopers, yet no identity has been confirmed. Every theory—from accidental death to elaborate escape—falls short of explaining all facts.
Lasting Impact on Aviation
D.B. Cooper’s audacious heist spurred major security reforms: skyjacking protocols were tightened, cash purchases faced extra scrutiny, and Boeing 727s were fitted with Cooper vanes—devices that prevent the rear stairs from being lowered in flight—making his exact method nearly impossible today.
More than half a century later, the D.B. Cooper skyjacking stands as the only unsolved air piracy in U.S. history—a testament to the hijacker’s boldness and the enduring allure of a mystery that refuses to yield its secrets.
