Continuity mistake: When the Gray and Houseman Construction Company vehicle is moving along at the beginning of the episode, the launching pad is raised, but after a quick cut to the crew, we return to the vehicle and the pad is now lowered.
Revealing mistake: The raindrops on the faces of Eddie Houseman and his colleagues during the storm are disproportionately large.
Suggested correction: This is part of the art style of the show - the same reason everyone's eyes are so disproportionately large, it helps the viewer to see details that would otherwise be too small to spot.
Continuity mistake: In several wide shots of Thunderbird 1 and Eddie's tractor on the cliff, the yellow pins that were fired from TB1 earlier and the rock they were holding have disappeared.
