I would like to see the concept of rescue operations entering the game, but in a way that wouldn't break the current game model.
For example, if you were just furballin like nuts and didn't care about dying (the 'thank you for shooting my chute, it just gets me into another plane faster!' crowd), you could just hit tower or type .ef like usual and do your thing.
If, however, you were trying to maintain a streak, you could keep it going by being brought back to a friendly base. Streaks would be a neat game element because the highest ranked pilots could be the ones that were really good, not just the ones that can stay online all day and get top scores via attrition.
Another use could be you doing a special type of mission that just spawned you somewhere inside enemy territory as a person and is set up so that if someone landed and brought you to a friendly base it would give something to the team (ala, simulating an intelligence operation or such) like information on higher production numbers or something.
Rescue operations would be completely voluntary, but it would benefit a score/perk-happy pilot who is rescued and would also benefit the rescuer in the form of perks as well. Heck, it could even be set up so you could split perks with the rescuer for even more encouragement.
Seaplanes would be a nice way to implement this for ocean bails, btw.
