Im not sure how the sortie works in game. BUT
Would it actually be possible say your fighting at a base with some squaddies, and One get shot down. He bails out. LAnds next to a friendly GV, and is able to join from that point, instead of getting a captured message. DOnt know if its feasable. But would be nice.
I know its been brought up with the Grand theft auto thing, but this is just he happens to be in the area you are. I mean Im looking at em froma GV, just think it would be kewl, to throw em in the tank, that Im in.
