DB Cooper Unsolved: The 1971 Hijacking and Suspects

The DB Cooper Hijacking

• ✈️ On Thanksgiving Eve 1971, a man using the name Dan Cooper purchased a one-way ticket on Northwest Orient Flight 305 from Portland to Seattle.
• 💼 He was described as a man in his mid-40s, wearing a black raincoat, dark suit, and a black necktie with a mother-of-pearl tie pin.
• 📝 Cooper handed a note to a flight attendant, which he later revealed contained a bomb threat, demanding $200,000 in cash and four parachutes.
• 💰 The ransom money was meticulously recorded by serial number, and the plane was refueled in Seattle before continuing its flight.
• 🪂 Cooper allowed passengers and some crew to deplane in Seattle, then ordered the remaining crew to fly towards Mexico City at a low speed with the landing gear down and the cabin unpressurized.
• 💨 He then activated the rear stairwell and jumped from the aircraft somewhere over the Pacific Northwest, disappearing with the ransom money.

The Investigation and Evidence

• 🔍 The FBI launched an extensive search, but found little direct evidence, including only a few fingerprints and the tie clip left behind by Cooper.
• 💰 In 1980, three packets of the ransom money were discovered by a young boy on a riverbank near Vancouver, Washington, deteriorated but with identifiable serial numbers.
• 📉 The FBI initially speculated that Cooper could not have survived the jump due to poor equipment, harsh weather, and rugged terrain, but the exact jump location and time remained unknown.
• 🕵️ The FBI suspended its investigation in 2016 after 45 years, citing the unlikelihood of Cooper's survival and the lack of new leads.

Key Suspects and Theories

• 🎖️ Many suspects were former military personnel, often with demolition or parachute training, including Richard Floyd McCoy Jr., a former Army Green Beret who committed a similar hijacking.
• ✈️ Richard McCoy Jr. is a prominent suspect, fitting many descriptions and having conducted a copycat hijacking, though the FBI did not officially consider him a suspect due to age and description mismatches.
• 👨‍✈️ Robert Rackstraw, a retired pilot with military parachute training, was investigated due to his physical resemblance to composite sketches and a history of criminal activity, but was eliminated due to lack of direct evidence.
• 👨‍💼 Kenneth Christensen, a former Northwest Orient mechanic and flight attendant, was considered due to his employment with the airline, fondness for bourbon, and the flight attendant's recognition of his photo, though the FBI cited physical description mismatches.
• 🕵️ Lynn Doyle Cooper (LD Cooper), a Korean War veteran, was identified by his niece, who recalled him being injured and bloody after a supposed turkey hunt around the time of the hijacking, and noted his admiration for Dan Cooper comic books.
