The One with... Alan on a bridge.
When Alan Tracy - in his Brains-designed racecar - returns to the motor racing circuit and triumphs, his rivals decide to remove the competition. They place Alan and Grandma Tracy on a bridge with a bomb and warn them: "Move - And You're Dead!" (Though not in those words)!
- Cool Car: Alan's racecar, designed by Brains.
- Context-Sensitive Button: The car-elevator in the parking garage is operated with the same two levers.
- Deadly Game: The car race that Alan participates in is notably far more dangerous than real-life races, what with racing on what looks like a desert track, cars crashing off the track and exploding, not to mention Alan's rival constantly trying to ram him off the road without apparent penalty or mention from the commentators (probably because they're on the explicitly stated, "area of the track that cannot be seen)."
- Expansion Pack Past: In this episode we learn that Alan was a professional racecar driver prior to joining International Rescue; a fact that has never been mentioned before and is never brought up again afterwards.
- He's Back: After having been retired for some time due to his duties in IR, Alan decides to return to racecar driving in this epsiode, much to the dismay of his rivals.
- How We Got Here: The episode starts with Alan and Grandma already on the bridge. While Thunderbirds 1 and 2 are on their way to save them, Alan tells Jeff about how they ended up there; justified because Jeff is trying to keep Alan focused so he doesn't faint and fall off the bridge in the scorching sun.
- Protagonist-Centered Morality: After rescuing Alan and Grandma (although unable to stop the bomb from going off and destroying the bridge), Scott then chases after Alan's rivals in Thunderbird 1 and actually opens fire on them, eventually causing their deaths when they struggle over the steering wheel and crash.
- Road Sign Reversal: The bridge Alan and Grandma get stranded on is not officially opened to traffic yet. Alan's rivals temporarily remove the roadsigns in order to lure the two onto the bridge and return them afterwards to keep other cars from reaching the bridge.
- Technology Marches On: One of Alan's rivals mentions he's struggling to get used to the car's power steering, despite it being set in the 2060s. As of 2018, virtually every modern car has such a feature.
