End of the Road (Thunderbirds)

"End of the Road" is an episode of Thunderbirds, a British Supermarionation television series created by Gerry and Sylvia Anderson and filmed by their production company AP Films (later Century 21 Productions) for ITC Entertainment. Written by Dennis Spooner and directed by David Lane, it was first broadcast on 25 November 1965 on ATV Midlands as the ninth episode of Series One. It is the 14th episode in the official running order.

Set in the 2060s, Thunderbirds follows the missions of International Rescue, a secret organisation which uses technologically advanced rescue vehicles to save human life. The lead characters are ex‑astronaut Jeff Tracy, founder of International Rescue, and his five adult sons, who pilot the organisation's primary vehicles: the Thunderbird machines. In "End of the Road", a construction company is under pressure to lay a road through a mountain range before monsoon season. In his haste to complete the job, civil engineer Eddie Houseman plants explosive charges that leave his vehicle teetering on a cliff edge. International Rescue must save Eddie, who was a former flame of Tin-Tin and who had just visited Tracy Island, without revealing their identities to him.

In 1966, Century 21 released an audio adaptation of "End of the Road" on vinyl EP record (Thunderbird 2, catalogue number MA 109) with narration from voice actor David Graham as regular character Brains. The episode had its first UK‑wide network broadcast on 10 January 1992 on BBC2.
