Cool ship, but the impression of the bad guys is spoiled somewhat by the boots. Oh no! It's the Fur-Trimmed Gang!

The Sun Saboteurs were a group of Earthlings who blew up suns. Which goes a bit beyond sabotage, if you ask me. Especially when entire planets are depending on it.

I was particularly bothered that the action is apparently set in 1984, 20 years after the colonies were established on the various alien planets -- even in 1955 I don't think anyone could believe that men would have reached the stars, fought a barbaric interstellar war, and destroyed Earth by 1964.

Well, to the misanthrope, we're capable of anything.
