Audio problem: After Colonel White thanks Captain Scarlet and Captain Blue at the start of the episodes, they reply with each other's voices.
Revealing mistake: As Delta Tango 19 takes off from the airport, there is a shot where it is actually landing. This can be seen from the fact that there is no runway behind them, as it is in front of them.
Trivia: Captain Scarlet's voice and face were based on the actor Cary Grant.
Question: How does Spectrum recover its wrecked SPVs?
