Character mistake: At the start of the episode, the Ground Controller says that the TVR-17 will be landed at 1400 hours, but a few seconds later he says 1900 hours, before they decide to change it to midnight.
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?
