Character mistake: Tim Casey is a Colonel, but Scott refers to him as a General in one scene.
Thunderbirds (1964)
1 character mistake in Edge of Impact - chronological order
Starring: David Graham, Ray Barrett, Peter Dyneley, Shane Rimmer
Plot hole: In order to build up suspense, Virgil and Brains stand on the Crab Logger as its dangerous fuel is pumped out, despite the fact that it is hanging on the edge of a precipice. In fact they could have left as soon as they had plumbed in the pipes to empty the fuel tanks - the whole procedure is controlled by Scott in Thunderbird 1 and they make absolutely no contribution to the operation at all. They do not need to disconnect the pipes; they are left behind and dropped from Thunderbird 1 as planned. They just stand there chatting about how much danger they are in until jumping clear at the very last second. Silly buggers.
Trivia: The shot of Thunderbird 2 flying in the dark is actually reused footage from a previous episode, "The Man from MI5."
