"Skyhook" is the eleventh episode of Thunderbirds Are Go!. It was first broadcast on Saturday June 6th, 2015.


Thunderbird 5, contacts Langstrom Fischler on CRUS, a high altitude weather station over the Indian Ocean. Suddenly, a hurricane damages CRUS’s fans, causing its hydrogen filled balloons to lift it higher into the atmosphere. On Thunderbird 5, John asks Langstrom about CRUS and he explains that the station’s systems take too long to manufacture. John contacts his brothers that they shall get to CRUS immediately. Virgil and Gordon blast off in Thunderbird 2, followed by Scott in Thunderbird 1.

When Thunderbird 2 reaches CRUS, Gordon assembles a pod with four heliblades and a grappling arm and flies it towards CRUS to fix its rotors. While Thunderbird 2 lowers its forward struts to steady the station, it gets electrified by a massive voltage, causing the ship to fall. Gordon re-docks the pod and re-activates Thunderbird 2’s systems via the pod’s controls. While Virgil and Gordon break off, Scott ziplines down from Thunderbird 1 and onto CRUS’s outer balcony. Suddenly, he gets knocked off by a series of plasma discharges which Brains referred to as “sprites”. Scott uses his grappling hook and he climbs back into Thunderbird 1’s cockpit and breaks off when Thunderbird 1’s engines start to stall.

When Langstrom tells Brains that his balloons are filled with super-hot hydrogen ions, he worries that the balloons will explode. He sends Alan to pull CRUS downwards with Thunderbird 3’s grasping arms and retro rockets. The fans break off and a piece of debris hits one of Thunderbird 3’s engines, causing the rocket to fall. Alan fires the emergency thrust vector and breaks off. The Tracys argue about saving CRUS but Scott tells them to calm down and says that they have no hope. John says that he can save them by flying Thunderbird 5 to a position right above CRUS and use the Space Elevator to latch onto the station and lower it to the ground. When Brains says that the cable wasn’t intended for that weight, John explains that Brains always over engineers his inventions. He dumps his spare supplies from Thunderbird 5’s cargo bay before firing the station’s powerful thrusters.

3.2 minutes later, John stops Thunderbird 5 and drops the Space Elevator after CRUS’s balloons explode and the mooring claw latches onto the station successfully. After being informed by Scott that the hurricane has doubled in size, John pulls CRUS into space by using the gravity ring as a spool. After John’s A.I program, EOS, warns him that Thunderbird 5 is losing orbit and venting atmosphere, John stops the spin and fires the bottom thrusters before CRUS hits Thunderbird 5. John lets Langstrom and his crew inside and he says that he wants a space station with a crew of monkeys. Scott tells John that Global Defence has revoked Langstrom’s space station plan and John demands that he must get off Thunderbird 5 before he has a sudden airlock failure.

  • Fischler: "Who employed you lot? Oh, That was me. Must have had the day off."
  • Fischler: "Start something that's already started? Sounds a bit daft to me."
  • Fischler: "Brains, Brains, Brains. You can't invent things if you go around worried about safety all the time."
  • Fischler: "Right! I'll put the kettle on!"
  • John: "You've obviously never seen me at the claw machine at the arcade. This is just another stuffed toy."
  • Scott: "That was just about the slickest maneuver anyone has ever seen!"
  • John: "Physics. Couldn't be simpler."
  • Fischler: "Two doors on an airlock, Mr Tracy? That's a bit excessive don't you think? What, do you like the sound of the airlock, do ya?"
  • John: "Now please get this man off my station before I have a sudden unexplained airlock failure."
