Revealing mistake: Near the end of the episode, Thunderbird 2 lands and reverses into its hangar. During this bit, if you look carefully you can see white smoke near the boiler on the far side of the hangar, only this smoke is apparently being sucked into it. This is the usual footage of Thunderbird 2 exiting the hangar played in reverse. (00:42:05)
Revealing mistake: When Thunderbird 2 returns to its hangar at Tracy Island, smoke can be seen flowing back down into units inside the hangar, revealing that this is simply reversed footage of the regular Thunderbird 2 launch sequence.

Pit of Peril - S1-E2

Revealing mistake: The raindrops on the faces of Eddie Houseman and his colleagues during the storm are disproportionately large.
