God, I Loved This Show As A Kid
...and as an adult, and a model maker, I still find it engaging but for different reasons.
I couldn't be separated for years from my Corgi model of Thunderbird 2.
Postscript: Plus, I vaguely remember watching this show religiously but had entirely blocked it out of my mind for nearly 50 years until I saw it in the side panel of videos on YouTube next to the one above.
