Catching fire before bailing would concern me a lot more than being trapped and most likely dying instantly upon impact. That, or being captured by the Germans, then thinking you’re about to be liberated by your Soviet allies, only to disappear to who-knows-where, spending the rest of your life betrayed and forgotten. But that’s just me.
None of those sounds like a good way to go (not that there are any, but there are degrees of unpleasantness). I had heard some of the SS or Gestapo made a “sport” out of hunting downed airmen who survived the shoot-down.
