Richard Floyd McCoy Jr. (December 7, 1942 – November 9, 1974) was an American aircraft hijacker. McCoy hijacked a United Airlines passenger jet for ransom in April 1972. Due to a similar modus operandi, McCoy has been proposed as the person responsible for the November 1971 hijacking of Northwest Orient Airlines Flight 305, attributed to the still-unidentified "D. B. Cooper".
