Thunderbirds

Security Hazard - S1-E26

Trivia: At the beginning of this episode, we see Chip Morrison being put to bed by his father. Chip was last seen as Bob Williams in 'Cry Wolf', whereas his father previously appeared as Dave Clayton in the episode 'Day of Disaster'.

Alias Mr Hackenbacker - S2-E3

Trivia: This episode features the largest number of characters (in speaking roles) seen in any Thunderbirds episode or either of the feature films.

Give or Take a Million - S2-E6

Trivia: At the beginning of the episode, when Jeff and Nicky are relaxing at Tracy Island, you can see models of Thunderbirds 1, 2, 3 and 4 on the table. These models were commercially available at the time of the episode's initial broadcast and were produced by J. Rosenthal (Toys) Ltd. Thunderbird 5 is not on the table as Rosenthal's model did not look like the genuine article.

Lord Parker's 'Oliday - S2-E4

Trivia: This is the only Thunderbirds episode in which voice artist Ray Barrett does not take part.

30 Minutes After Noon - S1-E18

Trivia: When Prescott is driving along in his car, he is humming the song "Marina" from "Stingray", another Gerry Anderson show.

Season 2 generally

Trivia: Throughout the second series there were three 'guest' voice artists: John Tate, Paul Maxwell and Charles Tingwell. Tate had previously voiced Solarnaut Camp in the episode 'Sun Probe' in the first series, whilst Maxwell and Tingwell would appear in the next Gerry Anderson creation 'Captain Scarlet & The Mysterons' as the voices of Captain Grey and Dr Fawn, respectively. None of these artists were credited in the end titles.

Pit of Peril - S1-E2

Trivia: When Thunderbird 1 leaves at the end of the episode, its booster rockets set fire to a small tree.

Trapped in the Sky - S1-E1

Trivia: In Thunderbird 5, a short piece of Barry Gray's "Formula Five" track can be heard. This was composed and recorded for another Gerry Anderson creation, "Fireball XL5".

Security Hazard - S1-E26

Trivia: This was the last episode in which David Holliday voiced Virgil Tracy. He was replaced by Jeremy Wilkin for the second season. Some sources say that Holliday left because he had to return to America, while others say he demanded more money.

Season 2 generally

Trivia: Although he was a regular character in the first series, the Hood does not appear in any of the six episodes in the second series.

The Mighty Atom - S1-E6

Trivia: This is the only Thunderbirds episode to feature the entire regular cast and all five Thunderbird craft.

Trapped in the Sky - S1-E1

Trivia: In this episode, Alan Tracy's voice is completely different from the one heard for the rest of the series. In his single, short line of dialogue, Alan is voiced by Ray Barrett, as Matt Zimmerman had not been employed when voice recording commenced (although he is credited in the end titles).

Trivia: International Rescue's headquarters was never actually referred to as "Tracy Island" throughout the whole series.

Trivia: Jeff, Scott and Virgil are the only characters to appear in all 32 episodes of the show.

The Duchess Assignment - S1-E23

Trivia: The Domo is a recycled version of the Excavator, which was used in the episode "Martian Invasion".

The Uninvited - S1-E5

Trivia: The Zombites' jet fighters are adapted and re-sprayed WASP aircraft from "Stingray".

Trivia: Gerry Anderson modeled members of the Tracy family on Hollywood actors: Jeff was modeled after Lorne Greene, Alan after Robert Reed, Scott after Sean Connery and John after Charlton Heston.

Security Hazard - S1-E26

Trivia: This episode features extensive flashback footage from "End of the Road", "Sun Probe", "Trapped in the Sky" and "Day of Disaster", and only 17 minutes of new material. The reason for this is because the previous two episodes, "Attack of the Alligators" and "The Cham-Cham" had gone over budget and a flashback episode was required to finish the show's first season.

Trivia: At Tracy Island there are portraits on the wall of Jeff Tracy's five sons: John, Scott, Virgil, Alan and Gordon. Gordon's portrait never bleeped once during all thirty-two episodes of the show.

Path of Destruction - S2-E2

Plot hole: In order to build up suspense, Virgil and Brains stand on the Crab Logger as its dangerous fuel is pumped out, despite the fact that it is hanging on the edge of a precipice. In fact they could have left as soon as they had plumbed in the pipes to empty the fuel tanks - the whole procedure is controlled by Scott in Thunderbird 1 and they make absolutely no contribution to the operation at all. They do not need to disconnect the pipes; they are left behind and dropped from Thunderbird 1 as planned. They just stand there chatting about how much danger they are in until jumping clear at the very last second. Silly buggers.
