Tracy family

The Tracy family are main characters in the 1960s British Supermarionation television series Thunderbirds and its adaptations, set in the 21st century.

Originating from the United States, the family live on Tracy Island in the South Pacific Ocean. Headed by Jeff, an industrialist and philanthropist, the Tracys run International Rescue, a search-and-rescue organisation operating on land and sea, in air and in space. They carry out their missions using a range of technologically advanced vehicles and equipment headed by a fleet of five craft called the Thunderbird machines, piloted by Jeff's sons.
