Thunderbirds is the beloved British children's science-fiction series that originally aired in 1965 and 1966. It's about the adventures of International Rescue, which consist of family and friends that saves the day no matter situation is thrown at them. The Tracey family lives in a hidden island, headed by their super-rich ex-astronaut father. Their remarkable rocket-like vehicles, called Thunderbirds, are stored under water. When they are ready to launch, the pilots yell the series' catch phrase, Thunderbirds are go!

The remarkable aspect about the series is that no humans appear on screen. All of the characters are played by marionettes with actor voice-overs. If the marionettes look familiar, that's because they were deliberately made to resemble some of the most famous movie actors of the day, including Sean Connery. The series was created by Gerry Anderson and Sylvia Anderson, the same creative team behind two other marionette-only children's series.

Although Thunderbirds was briefly popular in the UK, it took a long time before they made the jump over the Atlantic. Americans may recognize Thunderbirds in the form of movies broadcast in the early 1980s. The movies consisted of splicing several of the original half-hour episodes together, adding some extra music and cutting some scenes in order to make each movie two hours long.

Current Thunderbirds fans love the show for nostalgic reasons. Watching the episodes and collecting memorabilia help to recreate childhood feelings and optimism. The series often airs as reruns repeatedly in the UK ans Ireland. Attempts to make an American version of the series have failed. The Andersons claim they are working on making more episodes of their beloved children's classic, but so far nothing has materialized. Veteran science fiction actor Jonathan Frakes directed a big budget Hollywood movie based on the series, but it flopped.

Thunderbirds is a Action & Adventure series that is currently running and has 1 seasons (32 episodes). The series first aired on September 30, 1965. It has mostly positive reviews from critics and viewers, who have given it an IMDb score of 7.9.

Thunderbirds is available for streaming on the ITV website, both individual episodes and full seasons. You can also watch Thunderbirds on demand at Amazon Prime, Amazon, The Roku Channel, iTunes online.

Thunderbirds Full Episode Guide

  • A radio DJ, Rick O'Shea, is employed in a pirated radio station on an unlisted satellite, much to Jeff's chagrin. It is the reason for a rocket malfunction, but the space commanders don't know that, for they explode the rocket next to it, bringing the DJ and his assistant on a slow descent toward Earth. When IR arrive, however, the engineer jumps onboard Thunderbird 3, but O'Shea hesitates. Will Alan be able to save Tin-Tin's fave DJ?

  • Lady Penelope and Parker are on vacation in an Italian town, which is about to become the first to have all its electricity solar-powered. However, the machine has been wrongly positioned, threatening to burn the town to a crisp. The dish collecting the solar energy is 400 tons -- considerably heavier than the Thunderbirds can be able to lift. Can they save the town from disaster?

  • The aircraft industry turns to Hiram K. Hackenbacker (otherwise known as "Brains") to design a new, safer airline, which he does -- the Skythrust. Lady Penelope decides to hold a fashion show aboard the plane to prevent someone from stealing the revolutionary new fabric created by French fashion designer Francois. But one of his models reveals a gun and threatens to use it on the pilots unless the plane is diverted in the middle of the Sahara. Brains, hearing the model's refusal to land the plane, orders a missle to be shot at the plane. What will become of his invention and, more importantly, his passengers?

  • Lady Penelope invites a reluctant Jeff to go on vacation with her in Australia. Jeff hesitates, worrying about disasters that might happen while he would be away. He sees a report about a naval torpedo accident that sparks an underwater fire. International Rescue, with Scott at the head, responds, to Jeff's chagrin. When a second fire breaks out, Scott has no choice but to dispatch the Thunderbirds again. Will his second error be costlier than the first? And what will Jeff say about this one?

  • Jeff detects an intruder aboard Thunderbird 2, an intruder who turns out to be a little boy stowing away. Virgil is given the job of babysitting -- and keeping his mouth shut -- while Jeff gives the boys a stern lecture about the security breach. He finally cracks when the boy challenges his pride by saying Thunderbird 1 is the best ship. The boy gains information from everyone -- even Jeff "I have no sons" Tracy -- and soon leaves on a warning. But can he keep his secret?

  • An aircraft from the military is shot down while trying to make an important delivery. This has happened twice before, and Scott remembers hearing the song "Dangerous Game" being played on the radio all three times. Lady Penelope and Tin-Tin are sent to investigate the band responsible for the song, the Crass Carnaby Five. Can they make progress in cracking the case?

  • Two scientists enter an alligator-infested swamp to test out a revolutionary new drug, which is said to enlarge animals and therefore will put a stop to world hunger. Trouble arises when the drugs are spilled down the drain, causing the alligators to find them and...well, you can pretty much guess what happens next. Can International Rescue hold them?

  • Ocean Pioneer I, the world's most modern tanker, comes in contact of a Bermuda Triangle-like mist and suddenly explodes. Jeff sends Lady Penelope to investigate any signs of sabotage and promptly loses all contact with Thunderbirds 1, 2 and 5. What is causing the interference? And what will happen to Ocean Pioneer II?

  • Scott comes to the aid of a young boy, who supposedly has fallen over the side of a mountain and broken his leg. However, at the scene, the boy makes some kind of miraculous recovery.
