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 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 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.

Continuity mistake: When the Hood informs Commander Norman of Air Traffic Control that there is a bomb on Fireflash in the videophone booth, you can see that the Hood has one hand on the button panel, but the next shot shows him with both hands on the panel.

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.
