I think the desire (and this is just my opinion) is to add another element/option of what went on in the era. or maybe thier relative flew SAR and they want to relive/honor that.
Of course there would have to be some incentive to the downed pilot, maybe making downing in enemy territory versus freindly territory worth different amounts, or maybe if you got shot down in a perked plane, you wouldn't lose all your points.
for 99% of players they'll just tower and go back to flying, for the 1% (Occupy Aces High?lol) that would like to enjoy doing mundane tasks such as picking up downed flyers I'm sure they'd love it.
Or for that matter, perhaps we should have a WASP option, where you can't just spawn an airplane where ever you want, but someone else has to fly it half way across the map to your airbase.
As much as I'd like to see little side things like that developed, I don't think its the most cost effective use of development time/effort (even though I'd love doing it!)
