Continuity mistake: When the door of Pod 1 opens after Jeff realises there is a saboteur on board, we see three vehicles in the pod and beside the Monobrake there is a red unit which has a windshield on it. However, when we see Chip appearing in the next shot, the windshield has gone.
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.
Other mistake: When Scott and Virgil are putting Chip to bed towards the end of the episode, the globe in Chip's bedroom is upside down.
Continuity mistake: When Morrison is looking out of the window in Chip's bedroom, he closes the shutters and walks away from the window, but in the next shot he is standing next to Chip's bed.
Visible crew/equipment: When Thunderbird 1 returns to its hangar at Tracy Island at the start of the episode, the wires used to lower the rocket into the hangar can be seen.
Continuity mistake: When Thunderbird 2 is inside the hangar, it unloads Pod 1, but the numeral on the puppet-sized pod door in the close-up shots doesn't match the one on the model pod seen in long-shot.
