Continuity mistake: When Virgil is seating at the cockpit during the launch sequence of Thunderbird 2, he is wearing the clothes he wears on Tracy Island and his International Rescue costume appears. But when Alan comes down the lift, Virgil has suddenly changed into his IR costume.
Audio problem: When Lovegrove realises that Lambert is still in the vault, he is talking with Carter, whose voice is initially that of Shane Rimmer but then changes to a completely different voice provided by David Graham.
Factual error: In the Tube, Virgin and Allan are seen going from Piccadilly Circus station to Bank station using the same tunnel. These two stations are not even on the same line.
Visible crew/equipment: When Lambert is leaving his office in the vault, the shadow of a puppeteer is visible on the door frame.
Character mistake: The situation in this episode is that a clerk, Lambert, is trapped inside a bank vault that is having the air removed. When IR arrives they focus all of their efforts on forcing a man-sized entrance before the air runs out, but don't consider first making a small hole to allow air in, thus giving them plenty of time to create an entrance afterwards.
Continuity mistake: When Thunderbird 2 lands on the London Heliport, the sky has suddenly changed from daylight to nighttime.
Continuity mistake: When we see a close-up of Light-Fingered Fred in the prison cell, the games of noughts & crosses on the wall behind him are completely different to the ones seen in previous shots.
Revealing mistake: When Lady Penelope congratulates Parker in FAB1 after leaving the bank, the background shows that the car makes a sharp turn to the left, but Parker's steering wheel hardly moves.
Continuity mistake: When Parker is sitting at the table waiting for his meal prepared by Lil, you can see that his knife is pointing to the left, but when Lil says "Now listen here, Nosey!" we cut back to Parker, and the knife is now facing straight.
Continuity mistake: When they are travelling the disused London Underground tunnels, Virgil is on the red hoverbike and Alan is on the blue hoverbike. In the next shot, they have swapped bikes, but when they arrive at the bank they have swapped back again.
