Paul Joseph Cini is a Canadian plane hijacker who was the first person to perform a skyjacking with a planned escape by use of a parachute. In November 1971 Cini boarded Air Canada Flight 812, and—posing as an international terrorist—proceeded to hijack the plane. During the next eight hours, the plane made several mid-air diversions from its original flight plan that included a stop in the United States in order to pick up ransom money. Cini, who often became agitated during the event, was kept calm by a flight attendant, Mary Dohey, who had a psychological background before working for the airline. The hijacker was overpowered by Dohey and two additional members of the flight crew when he attempted to bail from the plane over the Alberta, Canada, wilderness.
