The Mighty Atom (Thunderbirds)
The only Thunderbirds episode with all characters and machines.
"The Mighty Atom" is an installment of *Thunderbirds*, the British Supermarionation series from Gerry and Sylvia Anderson, produced by AP Films for ITC Entertainment. Dennis Spooner wrote the script, David Lane directed, and it aired on 30 December 1965 on ATV Midlands as the sixth episode of Series One in production order. Set in the 2060s, the show follows International Rescue, a team using advanced vehicles to save lives, led by ex-astronaut Jeff Tracy and his five sons who pilot the Thunderbird craft. In this episode, the Tracys' enemy the Hood attacks atomic irrigation plants in Australia and the Sahara.
The story begins before International Rescue's founding, when the Hood spies on an Australian desert atomic irrigation plant. A security guard spots him, a gunfight breaks out, and a bullet hits a gas cylinder, sparking a fire that destroys the facility. Controller Wade and his staff are airlifted to safety before the reactor explodes, and a radioactive cloud threatens Melbourne but is dispersed by strong winds. A year later, the disguised Hood hypnotises science conference delegates and steals the "Mighty Atom"—a mouse-shaped, artificially intelligent roaming surveillance device. He travels to the Sahara, uses it to photograph a new automated irrigation plant run by Wade and his assistant Collins, then sets explosives around the plant's reactor to create a disaster that will lure International Rescue, hoping to photograph the Thunderbird secrets. With a second nuclear explosion imminent and no wind to save the region, Wade calls for help. Jeff sends Scott in Thunderbird 1. Lady Penelope, visiting Tracy Island with Parker, joins Virgil and Gordon in Thunderbird 2 carrying Pod 4. At the North African coast, Gordon launches Thunderbird 4 to the plant's seawater inlet, while Scott and Virgil don protective suits to realign control rods and stabilise the reactor. Gordon torpedoes the inlet, cutting off seawater intake just in time to prevent an explosion. Left alone in Thunderbird 2, Penelope—terrified of mice—screams when the Mighty Atom tries to photograph the cockpit. Later, at his Malaysian temple, the Hood connects the device to a computer, only to find all images are of Penelope's frightened face. Enraged, he smashes the Mighty Atom to pieces.

Lore & Background
The episode opens with the Hood spying on an atomic-powered irrigation plant in an Australian desert. A gunfight with a security guard ignites a fire that destroys the plant, and a radioactive cloud threatens Melbourne before being dispersed by wind. One year later, the Hood hypnotises delegates at a science conference and steals the Mighty Atom, an artificially-intelligent roaming surveillance device resembling a mouse. He uses it to photograph a new automated irrigation plant in the Sahara, then detonates explosives around its reactor to create a disaster that will lure International Rescue, hoping to photograph the Thunderbird machines.
International Rescue responds: Scott and Virgil enter the reactor room to realign control rods, while Gordon launches Thunderbird 4 to destroy the plant's seawater inlet, preventing an explosion.
Reader's Guide
"The Mighty Atom" holds a unique place in Thunderbirds history as the only episode to include every regular character and all Thunderbird machines, and as the debut of Thunderbird 4 on a rescue mission. Critical reception is mixed: TV Zone magazine names it the worst episode of the series, citing the Hood's ineptitude and the reliance on Penelope's fear of mice to thwart his plans. Tom Fox of Starburst gives a more positive rating of three out of five, noting "plenty of curious aspects." Chris Bentley, author of The Complete Book of Thunderbirds, calls the episode "surprisingly effective" despite International Rescue's absence from most of its first half, and regards the radioactive cloud scenes as some of the "eeriest" of the series. Marcus Hearn, author of Thunderbirds: The Vault, considers the "sinister" music effective but argues that Penelope and Parker "clutter" the plot and that Penelope's phobia "diminishes" her character. Sylvia Anderson wrote that the Mighty Atom itself "strains credibility" while comparing the nuclear explosion to the real-life Chernobyl disaster. Media historian Nicholas J. Cull notes the episode plays on themes of nuclear fears. Fred McNamara of ScreenRelish ranks a scene between Parker and Kyrano as the fourth-best moment of the series.
