Trivia / Thunderbirds S 1 E 20 Move And Youre Dead

• Out of Order: This is the episode in which Grandma moves to Tracy Island, so it must happen much, much earlier in the series chronology than its broadcast placement. It was #9 in production order, but when the earliest episodes were expanded to fifty minutes, Grandma was added to the new scenes of five of them. In the final reckoning, this episode is chronologically the fourth episode.
• Technology Marches On: One of Alan's rivals mentions he's struggling to get used to the car's power steering, despite it being set in the 2060s. As of the early 2020s, virtually every modern car has such a feature.
