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.
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.
Audio problem: After Colonel White thanks Captain Scarlet and Captain Blue at the start of the episodes, they reply with each other's voices.
Factual error: When we see the SPV escaping from the Culver Atomic Centre, it is night time. However, when we see Number 3 Tracking Vehicle, it has changed back to daytime.
Continuity mistake: At the very end of the episode, where Captain Scarlet, Captain Blue and Lieutenant Green are about to enter the airlock, their recognition badges are gone. Once they are inside the XK3 rocket, the badges have returned.
Visible crew/equipment: At the start of this episode a sniper lowers himself towards the President's window on a rope, watch the bottom right of the screen, you can see a hand lowering the puppet.
Suggested correction: Having re-watched the beginning of this episode several times, I'm still not seeing the hand.
Visible crew/equipment: As Blue escapes from the fake Cloudbase, a puppeteer's arm can be seen throwing the puppet through the window.
Continuity mistake: When Colonel White is being lowered onto the submarine, you can see that the harness is around his chest with his arms outstretched, but as he comes down the last few feet, he is gripping the harness strap with his hands.
