The points are based on where the airplane landed not the pilot. a pilot that is brought back to base but left his airplane on a ditch in the middle of nowhere doesnt really deserve more points.
and for the record you could get more points most of the time by upping another airplane and shoot something than waiting for somebody to go pick you up. your "saved" points may actually cost you more unless you are rescued next to the runway.
and if the rescuer is to get points, I can just imagine people upping and ditching right next to runway while a guy just rolls a few feet, picks up pilot, then ends flight, easy perks and points.
