What is the point of doing that in the Main Arenas? It seems like a lot of work for a feature that many won't use. What is your proposed benefit of the search and rescue? Do you not see how hard a time people have even getting supplies less than a mile from the GV spawn? What makes you think that someone is going to up and fly several sectors to "rescue" your pilot for... what, half of the five perks you just got or something? I don't see it.
If you want it for the purposes of immersion, the only pilots that would get sought out and rescued were those not shot down over enemy territory, i.e. American pilots shot down over the Pacific, British/German pilots shot down over the English Channel, and so on and so forth.
I'm not trying to be overly critical, just trying to get you thinking about all the aspects involved here.
