While I really did not watch the show, I do remember the ships :). This one I particularly like due to the removable pod with Thunderbird 4 inside. Thunderbirds came from Gerry Anderson who also did UFO and Space 1999!
if I remember correctly, Thunderbird 4 was just a submarine and couldn't fly. Hence it needed to be trnsported around by Thunderbird 2. I could however be mistaken/
