Continuity mistake: When we see The Hood's plane crashed into the General's mansion in a view from Thunderbird 1's cockpit window, there is a red car parked near the mansion covered in dust. But after Scott says that the stolen film could not have survived that smash, we cut back to the mansion and the dust on the red car has disappeared.

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.
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.
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.
Continuity mistake: Throughout series 2, the five pictures of Jeff Tracy's sons on the wall at Tracy Island are completely different to the ones seen in the first series. But when Scott prepares to launch Thunderbird 1, you can see the picture of John is the one seen in series 1.
Continuity mistake: During the second rescue, Thunderbird 2 releases the pod containing Thunderbird 4 on the water. But when we see Thunderbird 2 next to the collapsing oil rig, the craft can be seen with the pod in it.
Continuity mistake: When Thunderbird 4 comes out of the pod with the sealing device, there is a "4" on the back of the craft, but when it goes to clamp the device over the base of the fire jet, the "4" has disappeared.
Continuity mistake: When Sir Harry drives Lady Penelope down to FAB1 in his jeep, he is wearing a yellow helmet in the zoomed-out shot. When he is seen in close-up he is no longer wearing the helmet. Then, when the shot zooms out again, he is wearing the helmet.
