Very interesting link, thanks! "Klingon Mothership"?!? (well, the Federation "mothership" looks like a predecessor to Earth Spacedock). And it's obvious that "Buck Rogers" starfighter started as a (rejected) design for the colonial BSG Viper.
As some of you will know the animation sequence in the "Star Wars Holiday Special" featured a rebel base located within an asteroid in the beginning. Was that "inspired" by the McQuarrie artwork for "Planet of the Titans"?
