Thunderbirds Wiki is a collaborative website about Thunderbirds and its associated spin-offs. Originally a mid-1960s British television show devised by Gerry and Sylvia Anderson and made by AP Films using a form of puppetry dubbed "Supermarionation", Thunderbirds followed the adventures of International Rescue, an organization created to help those in grave danger using technologically advanced equipment and machinery. The series focused on the head of the organization, former astronaut Jeff Tracy, and his five sons who pilot the incredible "Thunderbird" machines.
