Again!
And no, I'm not really concerned about it, since I am talking time away from the game anyway. However, I asked a few of the guys that have left the game what it was that upset them so much as to leave and this was the issue (no penalty for bailing which they see as a waste of their time with no reward).
I would like to suggest that when someone bails from their bomber that the bomber slow to stall speed, gear and flaps come out, and the formation basically descends in "surrender" mode; easy meat in other words. The original pilot can log off, relaunch or what have you, but if they get shot down then it still counts against their score (although their name will not be announced to their attacker).
This is a fair and equitable outcome, because there are still bomber pilots that can reach their target and make it home.
