Strangely even after 7 pages it seems most people are completely missing the entire point/nature of the problem
I believe that most of the time it's not about denying the enemy a kill. It's not about farming perks (and the players who bomb and bail likely wouldn't care if they lost perks for bailing).
They do it so they can drop their bombs and then immediately re-up and go drop bombs somewhere else without having to fly all the way home. Significantly increasing their contribution to the war effort.
If you make a penalty to punish bomb + bailing, or institute a mechanic to prevent it, these guys will just auger.
Just the same as the old saying "You can't fix crazy"...when it comes to online gaming, you also can't fix lame
