Starring: David Graham, Ray Barrett, Peter Dyneley, Shane Rimmer
Audio problem: When the Reactor Station Guard catches The Hood taking pictures, he can already be heard blowing his whistle before he finishes saying "Hey, what are you doing?"
Audio problem: When the second reporter says to the first reporter, "Panic's over then. Did you hear the cloud got blown away?", it is said by David Graham instead of Matt Zimmerman.
Revealing mistake: When the dummy plane is shot out of the sky by the fighter pilot, a piece of the plane shoots off into the top left of the screen and bounces off the sky background. (00:23:05)
Trivia: The shot of Thunderbird 2 flying in the dark is actually reused footage from a previous episode, "The Man from MI5."
