Tracy Island is the home of the Tracy family in the Gerry and Sylvia Anderson 1960s television series Thunderbirds. Located in the South Pacific Ocean, the heavily camouflaged island's ulterior function is to serve as the secret base of the International Rescue organisation.
Thunderbird 1 is launched from a hangar underneath the island's retractable swimming pool, at the foot of the main Tracy Villa. The entrance to the Thunderbird 2 hangar is concealed by a false rock-face and leads onto the island's runway. On exiting the hangar, the palm trees lining the runway swing outwards to accommodate the wingspan of Thunderbird 2. After taxiing along the runway, Thunderbird 2 takes off from a hydraulic launch platform. Thunderbird 3 is launched from underneath the Round House. Features such as the outside staircase descending to water, the large windows, and the prominent stone chimney, suggest that the design was inspired by Frank Lloyd Wright's Fallingwater House. In the 2004 live-action film, a projection of the flightpath from Tracy Island to London clearly shows the former as being located in the Atlantic Ocean, whereas in the original TV series the island was located in the Pacific.
