Continuity mistake: When Alan contacts his father at Tracy Island, Jeff asks him "How's the situation, boy?" Alan informs him that Grandma has passed out in the heat and Alan's face is covered in sweat. But after a quick cut to Jeff saying "Passed out?" we return to Alan, and the sweat on his face has disappeared.
Move - And You're Dead - S1-E20
Continuity mistake: As Alan makes his telecall to Grandma, the close-up of his hand dialing her number shows the push-button dial panel with letters on the left and numbers on the right, but on the puppet-sized telecall unit, the numbers are on the left and the letters are on the right.
Move - And You're Dead - S1-E20

Continuity mistake: When we first see Virgil in the cockpit of Thunderbird 2 in the launch sequence at Tracy Island, he has nothing on his head. Later on, when we see both him and Brains, Virgil is now wearing his International Rescue hat, but when we see Virgil after the launch, the hat has gone.

Move - And You're Dead - S1-E20

The Duchess Assignment - S1-E21
Continuity mistake: After the Duchess has been rescued by "those romantic young men from International Rescue," when the Duchess removes the canvas from her umbrella, in the closeup (with human hands) she's wearing a pink button-down, but in all other shots there are no buttons whatsoever. (00:45:20)
The Duchess Assignment - S1-E21
Continuity mistake: The pod chosen for Thunderbird 2 in order to rescue the Duchess from the burning house is Pod 3, but if you look carefully when the Mole is coming out of the pod, you can see "Thunderbird 2 Pod 4".
Continuity mistake: The broken section of monorail track that is attached to the top of the centre coach when Thunderbird 2 lifts it away from the bridge is significantly longer when Virgil sets the coach down on the mountainside.

Continuity mistake: When Kalp makes his surprise appearance via Lopez's secret waterway, after shooting Scott's gun out of his hand, he holds up a test tube of Theramine. As he says, "Remarkable discovery." in the close-up, the position of Kalp's hand differs. (00:34:10)
Attack of the Alligators - S1-E23
Continuity mistake: During the after-mission chat, Alan is wearing a bandage above his left eye due to an injury he picked up on duty. If you look carefully this bandage sometimes changes between shots; it is particularly noticeable when he's in the bathroom with Tin-Tin. Also, the bandage is too small and too high up to have covered the injury adequately. (00:45:25)
Attack of the Alligators! - S1-E23
Continuity mistake: When the giant alligator surrounds the house and starts to attack it, the pattern of its tail in a close-up is completely different to the pattern of the alligator as seen in a long-shot.

Continuity mistake: When Jeff and Virgil are talking about how to deal with the alligator situation at the house, Jeff says that Pod 6 would be the best choice. Yet when Thunderbird 2 arrives at the scene, it is not Pod 6 that has been chosen - it is Pod 4.
Continuity mistake: After Scott realises that someone has tampered with TB1's camera detector, when it cuts to the movie set's camera, Agent 79's (the Hood) disguise eyeglasses are hanging beside the mask, but in the next shot the eyeglasses have vanished. (00:29:50)
Continuity mistake: When Thunderbird 1 arrives at the danger zone, it descends with wheels on the end of the landing gear, but when Thunderbird 1 lands, it lands with skids on the end of the landing gear, and the wheels are no longer there.
