The Flying Dragons also known as FDS are a well known Chinese American street gang affiliated with the Hip Sing Tong; they are active in New York City's Chinatown and New York Satellite China towns, and have a presence in Hong Kong, Canada and Australia. The gang moved heavily into heroin trafficking after the Italian-American Mafia lost the trade as a result of the Pizza Connection prosecutions in the mid-1980s. The Flying Dragons are believed to have been started during the late 1970s to early 1980s.
