Karajorma, I looked at the Perseus and yes, it is missing the cockpit glass. And after looking at the Boanerges, fishguts is correct as well. But I also found out that when I do those single player missions massive battle 1 and 2, not every single Terran and Vasudan fighter/bomber have the new afterburner effects. To be exact, the only four ships that have this feature during the single player mission are the Ares, Erinyes, Myrmidon, and the Zeus. What's even worse is that the Herc has no afterburner at all. Yet, when I play in the main FS2 campaign, most of the ships get their burners back.... I have not progressed far enough to view all of the Terran and Vasudan fighters and bombers, but the Ursa has no effects. Is anyone else in the same situation?
