Thunderbirds

The Fireflash, on its maiden flight from London to Tokyo, is sabotaged by the Hood, a criminal who has learned of the formation of International Rescue, and is unable to land. The Hood's attack is intended to draw out International Rescue so he can record secrets of its machinery for sale to the highest bidder, an attempt thwarted by the intervention of the organization's London Agent.

While returning from a mission, Thunderbird 2 is seriously damaged when it comes under attack from a new, high-speed U.S. Navy strike vessel, the U.S.N. Sentinel.

The Hood sabotages the Red Arrow aircraft programme. One of the planes crashes into the TV Tower in England during a brutal rain storm, and International Rescue is summoned to save the engineers inside the tower before it collapses; making their job trickier apart from the driving rain and winds at the site is that the Red Arrow's director, a long time friend of Jeff, is fired from the project and stays at Tracy Island, forcing the Tracys to draw him away and thus remain oblivious to International Rescue's existence.

The Allington Bridge collapses while a space rocket is being transported over it, trapping the rocket on the riverbed and inadvertently initiating its automatic countdown. International Rescue is called upon to save the crew before the rocket launches.

The Erdman Gang has developed an ingenious technique of having their work carried out – an explosive bracelet that can be removed only at the designated target. A secret agent's attempt to infiltrate the organisation backfires as he is left trapped in a plutonium store. International Rescue face a race against time to prevent a massive nuclear explosion.

Brains and Tin-Tin set off on an expedition to retrieve sunken treasure from Lake Anasta. The Hood has also set his sights on the riches and plans to put both Brains and Tin-Tin in grave peril.

International Rescue's security is jeopardised when Tin-Tin's close friend Eddie Houseman, who recently visited Tracy Island, takes drastic action to save his road-construction company's threatened contract by planting explosives to tear open a jungle mountainside, and the ensuing chaos leaves him trapped on a cliffside in a truck with another case of explosives on board.

While returning to base, Scott is attacked by mysterious fighter aircraft and shot down over the Sahara. He is discovered by two archaeologists, who send him on his way, only to find themselves entombed within the lost Pyramid of Khamandides.
