I'm all for adding new reasons to add new aircraft types. This will add extra dimensions to the game. I've used YAKs and IL2s to spot vehicles for my buddies on the ground.
If HTC could allow downed pilots to get lifts from aircraft or GVs then there's an opportunity for lighter planes (e.g. Fi Storch, Lysander) or even smaller faster vehicles (Jeep, 15cwt, Kubelwagon) to pick 'em up. Maybe they can reclaim some perks too to encourage bailing out rather than /ef.
It doesn't much of a change to me to add this nice little 'rescue' feature.
- maybe an ambulance to 'heal' a downed wounded pilot - or two?
