bsmith1702 was recently going over the killboard in Wing Commander 3 and noted that while it called out ace kills specifically, capital ship destructions were not included. It's just a fighter killboard. Then he had a truly "eureka!" moment. Most pilot rosters like this are sorted either by displayed name or number of kills. The WC3 board isn't ordered either way though, so it's easy to dismiss the question and assume they're more or less randomly assigned. But actually, the pilots are listed by each character's last name, not callsign! That's a pretty cool realization. Jace Dillon comes after Wingston Chang who comes after Laurel Buckley and so on. And now you're an even smarter Wing Commander fan because you know!
Another random thing I noticed was how the names are listed in the kill board. At first it didn't make much sense to me (and I liked how in WC1 the names were ranked by number of kills). Then I noticed that the callsigns are listed, but they are ordered alphabetically by last name (Buckley, Chang, Dillon, etc.) Blair is listed last (probably for the benefit of the player) and I guess they alphabetize Hobbes either by his callsign or using "Hhallas".
