Season 1

1. International Rescue's Finest

This episode starts innocently enough with Sarah Ashley flying to Langford to meet Mark healy, his wife Becky and their friends Nicola Foster, Charli McCoy and Nathan Thomas. Though on the maiden voyage of an atomic airliner capable of flying six times the speed of sound, Sarah's flight may be delayed -- permanently -- as Dr Diablo, Mark's evil brother, has hidden a bomb in the vessel's landing gear.

Will International Rescue arrive on time, or will its first mission come to a fiery conclusion? And what about the separate plan to be implemented before its arrival, which involved landing someone on the doomed plane's wing to remove the explosive? And, perhaps the most important question of all, will Nathan ever see Sarah again?

Unfortunately, the specialized gear needed for the rescue is aboard Thunderbird 2, which has yet to arrive. If all goes according to plan, its arrival will leave a 10-minute window in which to save the plane. Will that be enough, assuming Thunderbird 2 will be on time?

While the loss of 600 lives apparently means little to Dr Diablo, the sabotage is merely the first part of a bigger plan, one that involves photographing Thunderbird I. After evading capture by the police, Dr Daiblo is seemingly in the clear -- until Numbah Six enters the picture! Will she put an end to Dr Diablo's fiendish plot? Maybe not, but she'll look good trying!

3. Special Assignment

International Rescue impart the Healy Team with a "special assignment" which is to consciously allow Mark to loose inadequately at a casino, and to place himself on their debt owners list for 5,000 credits. When this is reported to IR Headquarters, Thunderbird 86 fires the gang on the spot, for improper use of the organisations' code of conduct, and the Thunderbirds are taken away from them.

Living in a inexpensive, shabby hotel room temporarily, a pair of Dr Diablo doubles, posing as sought after gangsters, formulate a deal with the now departed Healy Team, with Mark's I.O.U. for 5,000 credits, in return for the Thunderbirds, which will be utilized to brake into the Nevada Nuclear City Complex, with an atomic incendiary device, which will obliterate the whole of North America.

NOTE: Additional scenes are inserted in this episode, showing Steel and Kramer's motorcar accident down the hillside, their Mysteronised doubling, and Thunberbird 274's briefing to the Spectrum officers, following the broadcast of Dr Diablo's latest threat.
