Well that's odd, because I have a whole ton of mods and they bail out just as much now as they always have. On a few rare occasions I've seen bomber crews stay in a mortally-wounded bomber and try to recover, but other than that, the only things preventing them from bailing are high speed or death. I've also never witnessed enemy aircraft strafe wrecks - it seems seldom enough that they even strafe relatively intact AC.

Exactly how fast were they going when they didn't bail? That could explain it, assuming you didn't kill the aircrew and not notice...
