As it is now, there is no cost to bailing out of a perfectly good set of bombers. You just end up back in the hanger. Perhaps some kind of post-flight evaluation & results (consequences) might help - insert it before they get back to the hanger.
Something like this:
You land successfully... quick 5 second video of your crew chief saying welcome back sir! Maybe some stats (elapsed time, kills & assists, hit percentage, etc).
You ditch on the field, or land a shot up aircraft at your base... 15 second video of your crew chief (think of the guy from Baa Baa Black Sheep

) screaming "You college-boy PUKE... how in the hell do you expect me to fix this aircraft? They can train monkeys to fly better than that... etc", then you end up in the hanger.
You bail out successfully... 15 seconds of you walking home through the wilderness, followed by 15 seconds of your crew chief screaming "Boy, where the hell is my aircraft? At least a monkey would've brought it back when he was finished with it..."
You bail out and are captured... 15 seconds of you tunnelling out of the enemy prison camp, followed by 15 seconds of you skulking around running home, followed by 15 seconds of your crew chief screaming "Back again eh? I suppose you think I'm going to let you have one of my aircraft..."
You get killed... 15 seconds of your miraculous recovery in a military hospital, followed by 5 seconds of your crew chief saying "welcome back sir!"
You get the idea. The delay times and consequences could vary (maybe not bringing home your plane changes the minimum ENY for that player for a short period?) Just something so that there is an incentive to bring home a plane, or at least get back out of enemy territory before you bail.
