#1 - The Mighty Atom

Season 1 - Episode 14 - Aired 12/30/1965

A tour bus is being taken around the new Atomic Station in Australia that is reclaiming the desert. The reporters are not convinced of the safety of the project due to the risk of a nuclear explosion. Meanwhile the Hood is trying to discover the secret of the plant but is caught by security. In the gun fight follows, the Hood accidently hits a gas pump and it explodes. The fire rapidly spreads through the station and soon the staff have to evacuate. The only thing that could have saved them would be to cut off the sea water intake. The plant explodes and sends a radioactive cloud towards Melbourne. But about a week later the wind pushes the cloud back into the desert. 12 months later, a European professor has a group of army representatives to show off his new invention: the Mighty Atom. It is a very powerful camera concealed in a robotic mouse that takes photos of control panels by recognizing the profiles of people who use them. After a brief demonstration, one of the representatives is revealed to be the Hood in disguise who hypnotizes everyone and steals the invention. He immediately visits a new Atomic Station in the Sahara desert that is just beginning operations. Using the Mighty Atom, he takes photographs of the station's control room. After he completes his mission, he gets the idea repeat the accident that destroyed the Australian plant last year in order to lure out International Rescue and steal their secrets, too. He plants bombs around the plant and they explode, causing a fire that rapidly spreads. In the control booth, the controller realises that sabotage is afoot and calls International Rescue.

International Rescue has just wrapped up another successful mission, helping to extinguish an out-of-control blaze and pulling the men trapped by it from the bottom of a shaft. The mission hasn't run as smoothly as initially believed, however, as Jeff Tracy detects an intruder aboard Thunderbird 2. With blasters drawn, Jeff, Scott and Gordon converge on the hangar, only to discover the ""saboteur"" is a little boy that stowed away in an unguarded pod after excitedly witnessing the rescue in action. While Mr. Tracy gives three of his sons a stern lecture about the security breach, Virgil is supposed to be babysitting -- and keeping his mouth shut. He does a good job of it, until the boy challenges his manhood by saying that Thunderbird 1 -- Scott's ship -- is the best.

Lady Penelope and Parker are off on vacation, invited by a small Italian village to join in on a historic celebration. Thanks to a remarkable invention by a local scientist, the town is set to become the first to have all of its electricity needs completely powered by the sun. For Penelope and Parker, however, it seems like they've never left home, thanks to a rare rainstorm that's drenched the resort town. A porter at the hotel at which they're staying -- perhaps bitter about all the extra work the influx of guests has caused -- predicts disaster, claiming that the sun will seek revenge for the theft of its power. Initially dismissed as crazy, the porter's words seem prophetic, as the storm grows in intensity and sends the solar generator toppling over the side of a cliff. The town is safe for now, as the guests bask in the intense glow of the moonlight reflected by the generator once the storm has passed.

Just when it seems Alan and Brains will have to endure another story about the good old days of space exploration, Jeff Tracy is distracted by what Tin Tin considers music. Jeff may be a little out of touch with what's hip, but the music he hates so much broadcasts from a pirate radio station orbiting the earth. Tin Tin fails to see the harm caused by her favorite DJ, but Jeff does, saying that an unregulated satellite could cause a serious accident among all the other countless government-sanctioned ones. Right on cue, a rocket suffers a malfunction shortly after blastoff, and must be taken out after veering off course. Unaware of the music satellite's existence, mission control destroys the rocket right near it. The violent explosion jolts the vessel out of orbit, forcing the DJ and his engineer aboard on a slow descent toward Earth. Still worse, the engineer is trapped in the airlock after surveying the damage outside. Can anything save the DJ from a deadly crash and his engineer fr
