Tilt, I think you have a very good idea there.
One of the reasons for the bomber/bailer is simply Operations Management.
Get the most ordnance to the target as quickly as possible.
Time from takeoff to target is mandatory.
Any time spent in the air that you're not delivering ord. to target is wasted, therefore needs to be eliminated.
So, once the ord is out, you're wasting time in the air. Get out of the air and launch with more ord.
The only way you're going to stop that is to adjust the efficiency of the damage/time formula.
Now, perhaps as a motivation, if Tilt's idea is imposed, The damage done by the bombers that are abandoned by the bailing pilot should have the down time period reduced significantly.
Might not be efficient if the hangars you just leveled pop in 5 minutes ( before you could return the base with more ord ).
