"Edge of Impact" is the 16th episode of Thunderbirds, a British Supermarionation television series created by Gerry and Sylvia Anderson and filmed by their production company AP Films for ITC Entertainment. Written by Donald Robertson and directed by Desmond Saunders, it was first broadcast on 28 October 1965 on ATV Midlands as the fifth episode of Series One. It had its first UK‑wide network broadcast on 29 November 1991 on BBC2.[1]
Set in the 2060s, Thunderbirds follows the missions of International Rescue, a secret organisation that 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.
International Rescue's work is repeatedly disrupted by master criminal The Hood. In "Edge of Impact", The Hood's efforts to sabotage military test flights cause an experimental fighter to crash into a television tower, trapping a pair of technicians inside. With an old friend of Jeff paying an unexpected visit to Tracy Island, International Rescue must covertly spring into action to save the two men before the tower collapses.
