Continuity mistake: When Scott is in the cockpit of the Mole, he has two blue tubes in the holsters of his belt. But when he is cutting through the fire doors, the tubes have changed to one blue and one yellow.
Continuity mistake: When The Hood drives his van off the broken bridge whilst escaping the police, watch carefully; the van bounces off the rocks on the other side and starts to fall roof-first into the river below. However, when it cuts to the van falling into the water it falls in upright. (00:42:00)
Continuity mistake: Near the end of the episode, Jeff activates Operation Cover-Up to change the wall-mounted pictures of the International Rescue members from the usual pictures of them in their uniforms to ones of them in casual clothing before a doctor who has just examined Kyrano enters the room. However, while he and Jeff are talking, a couple of shots of Scott and Gordon contain enough of the pictures to show that they have reverted back the ones of them in uniform. (00:48:35)
Continuity mistake: When Thunderbird 2 leaves the hangar on Tracy Island, it appears that Pod 3 has been selected (Pod 2 is visible to the right of Thunderbird 2), yet when Virgil and Brains arrive at Mount Arkan, the Transmitter Truck emerges from Pod 6. (The same continuity error also occurs in the episodes 'Vault of Death', 'Move - And You're Dead', 'Martian Invasion', 'The Perils of Penelope' and 'Day of Disaster', probably due to the same footage being re-used for those episodes).
Continuity mistake: While Gordon Tracey searches for the crashed Fireflash wreckage on the seabed, the parting in his hair keeps changing sides from shot to shot.
Continuity mistake: When the Hood is taking photographs of Thunderbird 1 at London Airport, one of the photos shows the letter "T" of Thunderbird painted on the red nose cone. All other shots of the craft show the nose cone free of markings.
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.
The Perils of Penelope - S1-E3
Continuity mistake: When Lady Penelope is in her bed in the monorail, she is wearing a pink night dress, but when Penelope awakens to find an intruder outside her room, she is now wearing a blue dress.
Continuity mistake: When Scott and Virgil leave the Mole on their hoverbikes, their uniform sashes are over the wrong shoulder.
Continuity mistake: When the Carter family are driving in their car to the Thompson Tower, Joe is driving and Blanche and Tommy are sitting in the back. But when the car stops at the ticket machine, Blanche and Tommy have disappeared.
Continuity mistake: When Virgil is seating at the cockpit during the launch sequence of Thunderbird 2, he is wearing the clothes he wears on Tracy Island and his International Rescue costume appears. But when Alan comes down the lift, Virgil has suddenly changed into his IR costume.
Continuity mistake: When the Hood is taking photographs inside Thunderbird 1, we see a close-up of his hat. On the hat, it says "Airport Police" on the lens, but when we see a full view of the Hood, the words are no longer visible.
Terror in New York City - S1-E4
Continuity mistake: During the missile attack on Thunderbird 2, Virgil says "Missiles!" in the cockpit and his forehead can be seen to have sweat on it, but after a quick shot of the missiles flying through the air, we cut to Virgil again and the sweat has disappeared.
Move - And You're Dead - S1-E20
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.
Continuity mistake: In the pyramid, we see a closeup of Scott's hand grabbing the gun. The color of his uniform changes for a lighter blue in that shot.
Pit of Peril - S1-E2
Continuity mistake: When the shaft that Virgil slides down connects to Thunderbird 2, we can see Pod 3 to the right of Thunderbird 2. Seconds after Virgil's chair has locked into place, we see the pods slide across from left to right, including Pod 3. I thought that was to the right of TB2? It couldn't have been quickly moved to the left, as we see that Pod transportation is very slow. It couldn't of been a spare, as there is no sign of it when we see Pod 1, etc, roll to the right.
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.
Terror in New York City - S1-E4
Continuity mistake: In "The Ned Cook Show" portion of this episode, Dr. Godber is initially seen sitting in front of Bletcher with at least three rows of seats behind him, but, in another shot, he then appears two rows from the back sat in front of Jeff Tracey.
Continuity mistake: In the Thunderbird 2 hangar, Virgil selects Pod 5, but when the cliff face drops down, Pod 2 is on the right of Thunderbird 2 (instead of Pod 4, which it should be).
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.
