Its been quite a while since I played it (or anything FS-related for that matter), but I seem to recall that there was a line in "Homesick" where some pilot was talking about a rumor about the GTVA Colossus, but he called it the GTVA Colossal and that it had parts from 12 Lucifer-class destroyers as part of it, obviously a take on Kurtwood Smith's line from the Colossus cutecene where it says that 12 Lucifer-class could fit within its hull.
I also recall one of the concealed debriefing recommendations, where the debriefing officer is chewing out the other pilots for goofing off in the midst of it.
