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


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

When Thunderbird 2 reaches CIR.R.U.S, Gordon assembles a pod with four heliblades and a grappling arm and flies it towards CIR.R.U.S 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 CIR.R.U.S’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 CIR.R.U.S 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 CIR.R.U.S 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 CIR.R.U.S 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 CIR.R.U.S’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 CIR.R.U.S into space by using the gravity ring as a spool. After John’s AI program, EOS, warns him that Thunderbird 5 is losing orbit and venting atmosphere, John stops the spin and fires the bottom thrusters before CIR.R.U.S 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 Force has revoked Langstrom’s space station plan and John demands that he must get off Thunderbird 5 before he has a sudden airlock failure.

  • John: "You sure you're not still an evil computer program?"
  • EOS: "Ask my programmer... no, wait, that was you."

  • John: "How are the studies going, Mr. Fischler?"
  • Fischler: "Very well thank you. We've determined it is indeed a storm down there... a big one."
  • John: "Well, that's sure to rock the scientific community."

  • Fischler: "Who employed you, lot? Oh, that was me. Must have had the day off that day."

  • Virgil: "I'm plotting a course to stay well above that hurricane."
  • Gordon: "Don't worry, I'll keep an eye on it, you know, because hurricanes have an eye at the center."
  • Virgil: "I get it. Just wasn't funny. Go configure the pod, will you?"
  • Gordon: "Aye aye, captain."

  • Fischler: "Start something that's already started? Sounds a bit daft to me."

  • Fischler: "Brains, Brains, Brains. You can't invent things if you're going around all worried about safety, now can you?"

  • Virgil: "Doctor Gordon, your patient is ready."
  • Gordon: "Repair arms in place. The doors, please, Doctor Virgil."

  • Scott: "Can you give us a status report?"
  • Fischler: "Well, so far, your rescue attempts appear to be unsuccessful. International Rescue, ha, International Slow-Coach, more like."
  • Scott: "I meant a report on your status, not the... never mind."

  • Brains: "Thunderbird 2 absorbed the static charge. You should be safe."
  • Scott: "How sure is should be?"
  • Brains: "99 percent."
  • Scott: "And what happens if it didn't absorb all of the charge?"
  • Brains: "Let's focus on the positive, shall we?"
  • Scott: "Yeah."

  • 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 one more 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."

  • This episode marks the first time that non-International Rescue members have been on board Thunderbird 5.


  • Thunderbird 4 can be seen in its own launch bay as the lift from Thunderbird 5 leaves the island, but isn't there when Thunderbird 3 launches off the island later on.
  • The wristband communications device on Virgil's left arm changes colour to grey as he is attempting to get Thunderbird 2's systems back online. Later in the same sequence, when Gordon has control of the craft, the wristband is absent when Virgil crosses his arms.
