In Review: Thunderbirds Are Go – EOS

A series of cascading equipment failures lead John to realise that a rogue AI has taken control of Thunderbird 5.

Synopsis: A series of cascading equipment failures lead John to realise that a rogue AI has taken control of Thunderbird 5.

Review: This story for me is the most impressive yet to come from this new Thunderbirds series. It sees Thunderbird 5, which is the brains of International Rescue taken over by an AI, which John pretty much created. It is basically following on from the events we seen in last weeks episode where an AI took over a Train, and John had to engage it in games in order to help his brothers make the train safe again.

In this story. The AI, which is calling itself EOS has taken over Thunderbird 5 and is virtually in control of every system. EOS eventually locks John out to have him struggling to get back on board because he only has 15 minutes of air left before he is fully exposed to the ravages of space.

The relationship between John and EOS grows over time as the two engage in a battle of wits, but it is only when John thinks outside of the box and uses a back up system to get a message out to Lady Penelope that the rest of International Rescue catch on. EOS has been using a holographic composite of John in order to send messages to Tracy Island in order to let his brothers know that all is well.

There is a little comedy to be had on this episode, which comes unexpectedly from Lady Penelope, who believes initially that John is sending her selfies. I still wonder what exactly Lady Penelope is all about. She does not seem to be used all that much in this new series and is perhaps the least developed of the characters. But for the most part this story is a white knuckle ride as John, EOS and Alan in Thunderbird 3 battle each other to regain control of Thunderbird 5.
