Saint John Hawke is the brother of Stringfellow Hawke in the TV series, Airwolf. Referred to most of the time as Sinjin, Saint John is an MIA in Vietnam. Stringfellow has hidden the Airwolf prototype and will only return it if the government finds his brother and returns him to the U.S. After CBS ended the series after 3 seasons, the U.S.A. network ran a low budget, Canadian produced sequel in which Sinjin is rescued and becomes the central character. This series carries over none of the original cast or characters with the exception of Stringfellow, (Jan Michael Vincent) who appears in the pilot episode only. He is badly injured and asks his brother not to let him die in the hospital. St. John complies with the request, and it is never revealed if Stringfellow indeed died as a result of his injuries.
