I remember watching a episode about an a-1 skyraider picking up a another skyraider pilot after he'd been shot down in enemy territory in North Veitnam. I would imagine this could be possible for almost any plane.
Would love or hell could even have ditched plane repairs like a jeep can bring vehicle supplies. So that when you land with a botched radiator or something your friend can bring you some industrial duct tape and wd40 to fix all your worries!
