The TV series of Buck Rogers brought along a rather fine Starfighter in the large scale with firing missiles and a corgi junior version with sliding wings. One of Corgis most notable inclusions however was the wonderful Starship Liberator from Blakes Seven, although it only appeared in Junior scale, it was a surprisingly accurate and good model. Corgis artistic licence produced it in classic white and also later in a silver and yellow version. Yuk.
The Corgi 1985 catalogue was a real revelation for sci-fi enthusiasts, including all the above models, but headlining with a beautiful model based on a Frank Hampson design for a 'Dan Dare' car. Presumably to tie in with a proposed TV series again, the iconic fifties shape of the 'car' would have made a fine model in both large and small scales. I say 'would' because no trace of the toy ever appeared on the shelves and it disappeared from subsequent catalogues soon after as the show never got off the ground.
Apparently based on the Aranjet Supersport Aquagyro from the Operation Saturn strip (and again ill defer to more educated Dare afficianados for confirmation!), the toy would have had a rotating 'radiator' grille and flip out wings. The bubble canopy and sleek red body had me at the outset to be honest.
