Vintage 1960s British science fiction TV shows that never were

Zack sez, "If you like 1960s SF TV with lots of exploding models and strange names, there's a pair of unaired British pilots on YouTube well worth checking out. Roberta Leigh, who'd created the popular SF children's series SPACE PATROL, had a couple of shows not picked up in the mid-1960s. The first embed is THE SOLARNAUTS, about the crew on a space station that must battle the evil forces of LOGIK! Then there's PAUL STARR, a puppet show in the tradition of THUNDERBIRDS (and stars the voice of Ed Bishop, who'd later star in Gerry Anderson's UFO).
