Blaise attitude by Astronauts
The opening episode was a bit like Star Trek as they didn't seem to question why the humans spoke English and looked err human.
One of the astronauts quips that they could be on one of a thousand planets. If so surely being scientifically trained they might have shown some surprise that they were on an English speaking planet which they just assumed wasn't Earth just because some fruit looked strange.
I remember watching this series as a young kid back around 1974 and it certainly came across more of a boys own adventure series than a satire on human life. However it was still enjoyable and I'm sure with a sharper script it might not have been cancelled.
