This VHS released by Channel 5 uses the spelling "The Imposters."

  • The Satellite HQ interior and exterior sets would be reused as different buildings, in both Cry Wolf and Ricochet.
  • The EJ2 Jet, from Operation Crash-Dive, returns as the fake Thunderbird 2.
  • This is the only TV episode in which the real Thunderbird 2 does not make an appearance.
  • The episode title is sometimes spelled "The Imposters."
  • Eddie Kerr claims that this marks the first time that TV cameras were able to reach the scene of an accident in time to see the International Rescue team in action. This would mean the events in The Impostors precede those in Terror in New York City, even though it is later both by broadcast order, and by production order.
