Darn you ruined it Protostealth! Anyway, I think you'll find that there are a lot of allusions to different games and lots of forshadowing. Some of the MIAs go on to become members of the Grabacr and Ofnir squadrons. I am actually decently certain that one of the MIAs became a member of Alect Squadron (obviously KIA in the Leasath-Aurelia War).
And "Adler" is the Belkan codename for Arkbird, not the person piloting it. Adler is also the name of the unfinished ground-attack version of the FALKEN. "Schenze" is the codename for the Grunder Industries control facility.
Those aces whose detailed information is unknown is really interesting. One ace that caught my interest is Nachtigall... In my own and humble opinion. She must have some sort of connection with Bernitz... I dunno, just speculation.
