ITV airs the first episode of Gerry Anderson’s new live action series Space: 1999. Space: 1999’s lavish budget, sleek sets and impressive miniature effects work make it the TV science fiction saga to beat in the 1970s (at least visually). Isaac Asimov even reviews it in the New York Times, giving the show’s shaky science a pass in favor of dramatic necessity. 
The first episode of Sid & Marty Krofft’s Far-Out Space Nuts airs on CBS, starring Bob Denver (Gillgan’s Island) and Chuck McCann (Herbie Rides Again).
The 16th episode of Filmation’s live-action Shazam! series airs on CBS, starring Jackson Bostwick, Michael Gray and Les Tremayne. John Lupton guest stars in the second season premiere.

In a meeting with BBC Head of Series & Serials Ronnie Marsh, Dalek and Survivors creator Terry Nation – who has already found himself at odds with the producer of Survivors – pitches a new series idea. Described as “The Dirty Dozen in space,” Nation’s series idea envisions a slightly disharmonious group of rebels taking up arms against a totalitarian, almost Orwellian future government. The concept, which Nation names Blake’s 7 at the meeting, will take a few years to make it to the screen.
