Sheridan Peterson, who passed away on 8 January according to memorial website Legacy.com, was thought to possibly be the “Dan Cooper” who hijacked Northwest Orient Flight 305 on Thanksgiving eve 1971. Mr Cooper handed a flight attendant a note saying that he had a bomb and then demanded $200,000 in $20 bills and four parachutes. That was the approximate age Cooper was assumed to have been, and I closely resembled sketches of the hijacker.” On another occasion a photo came to light from a Boeing newsletter showing him dressed in exactly the same manner as the hijacker was said to have been during the 1971 flight.
