Yes, I read it long ago. Though they really stumbled on a grand formula with their “Wagon Train In Space”.
So grand that there are now several fan-based Star Trek TOS productions creating Internet episodes more or less based on the original series:
Star Trek: Phase II (which continues the five year mission with Kirk and Spock, et al.)

Starship Exeter (of the same class as Enterprise)

Starship Farragut (live action and also animation in the style of Star Trek, the animated series)
There are also several fan productions that are based on other shows from the series, particularly DS9 and Enterprise.

Never totally got the Wagon Train analogy as a kid because that show was a little before my time. But now watching Wagon Train on cable it makes perfect sense.
