The FBI is investigating a new lead in the 1971 D.B. Cooper case that remains the only unsolved airplane hijacking in the agency's history.
A retired law enforcement officer brought forward an item connected to a witness who may have been connected to Cooper. The FBI's Seattle office appears to be in the process of ruling out the possible witness, reports Jalopnik.
The day before Thanksgiving in 1971, a passenger going by the name Dan Cooper boarded a flight from Portland, Ore., to Seattle. Cooper lit a cigarette, ordered a bourbon and water, and handed the flight attendant a note stating that the Boeing 727 was being hijacked.
The plane landed in Seattle, and passengers were removed. A $200,000 ransom and parachutes were delivered to Cooper. The aircraft then took off toward Reno, and Cooper parachuted into the Pacific Northwest forest.
