From their website:
This 80-page 1991 edition moved the product further toward the current format. This issue is the only one that ever had a “theme” causing a hundred people to ask, every time we do another issue, what the new issues theme is. The fiction story GHOSTLIGHT (about a Federation fighter squadron) came along with an SFB scenario and a “behind the scenes” write-up, in game terms, of what was going on. The idea was to show writers how to make game counters, rules, and hexes into exciting stories. This issue also included the first-ever “class history” article (about Federation carriers).
