Media tells us that it's the people who have the big dreams that are killed, the people who have clear plans for the post-war world and their place in it. Memoirs tell us that those guys make it out okay, the ones who die are those who are convinced they will die.Such are the cruel fortunes of war.
A concerted Allied bombing campaign against Romania and continued fighting in Greece could well strengthen the Bulgarian Air Force. Historically they were really not particularly credible, mostly equipped with tired out 109Es and nicked D.520s, but with Allied bombers constantly thundering overhead and ground forces in active contact they might get more German aid. Perhaps a license/kit-build arrangement for Bf 109s like Hungary and Romania did? Another possibility might be spare Me 210Cs, after the debacle of the 210A and the redesign to the 410, the Hungarians quietly knocked out a few hundred 210Cs with overhauled aerodynamics but the smaller engines. The license agreement gave the Luftwaffe a third of these aircraft, but they seem to have been prejudiced against them and didn't use them much, eventually regifting them back to Hungary. They're perfectly functional multi-role heavy fighters that nobody wants, and Bulgaria is the Axis member nobody asked for. Surely a match made in heaven?
