"Trapped in the Sky" is the first episode of Thunderbirds, a British 1960s Supermarionation television series. Written by co-creators Gerry and Sylvia Anderson, it was first broadcast on ATV Midlands on 30 September 1965. The plot revolves around criminal mastermind the Hood, who sabotages the nuclear-powered airliner Fireflash prior to her maiden flight. Unable to land for fear of detonating a motion-sensitive bomb, and threatened by radiation leaking from Fireflash's overworked atomic reactor, the crew and passengers' only hope of survival is the newly formed International Rescue Organisation.
