The flight program unit from Renegade Rocket re-appears on the space station, with the rocket destruct codeword ZERO still present.

I'm sure the space station model re-appears in General Henderson's office in Court Martial.

The initials on the side of the station are OTC, but Weston calls it an OCT at one point.

Everyone calls it an OCT--apparently due to typos in the script.

How likely is it that, firstly, the rocket launch sequence would get fouled up, and, secondly, the astronaut eject system would also foul up? That scene where they elect to kill the astronaut to save other lives seemed a little chilling for a children's show. Of course, that can be said about a lot of sequences on Joe 90.

The implication seems to be that all of the available astronauts were dead or disabled. Five of them? That's all they have?

I liked Shane Weston's tone of voice when he was ordering Joe's space suit--especially when he icily repeated Joe's height to the confused "tailor".
