I bail out if my plane is crippled and going down. I also try to make it back to base and to land after I'm out of ammo or if I've just enough fuel to make it back. The reason isn't score (which isn't large for anyone like me, anyway, who doesn't fly that often), but to work in a small extra amount of realism. For this reason, I'd like it if the bailing process were more realistic (harder, such as requriring the opening of canopy and unbuckling; and lower probability of it being survivable, such as reducing probability of living through it the faster you are going). However, I agree that this sort of request would add to the game only for a small minority of players and that there are many higher-priority features that should take precedence.
