International Rescue Equipment UsedEdit

Non-International Rescue Equipment UsedEdit



  • This episode borrows some plot elements from The Impostors, albeit with International Rescue being regulated to an extreme level rather than being forced to shut down due to an external frame.
  • The aforementioned bridge rescue scene adapts some elements from Day Of Disaster, with the premise of a collapsing bridge and imperilled government personnel, and End Of The Road, where a truck is precariously balancing on a ledge. It also borrows some plot elements from City Of Fire, with a city located in a building in peril.
  • Scott flies in Thunderbird 2 with Virgil and Gordon for the first time as the co-pilot in this episode. Alan also flies in Thunderbird 2 for the second time as a passenger in this episode.
  • Interestingly, Gordon still uses his same animation when boarding Thunderbird 2 despite two extra characters in the same shot.
  • Near the end of the episode, Virgil is shown playing the piano much like his original counterpart.
  • When Colonel Casey asks the Janus Imposter who he really works for she asks him "Who's pulling your strings?" to which he replies "I'm nobody's puppet". This is of course a reference to the original puppet series.

Goofs Edit

  • Kayo mentions that she will give Brains a lift in Thunderbird Shadow, however, so far, Thunderbird Shadow is only seen to have one seat.
