Honestly no I wouldn't want that to happen.
That is your answer. It's all score related. You've been put down, shot down, or forced down. Your sortie is over. It would take a mere sliver of a fraction of the time to just reup a new plane and try again, but for perks, for kills, for score, for whatever reason you don't want to do that.
The person who last got a round in ya doesn't "deserve" the kill because he didn't get a kill if you can still land your ac refuel it and take off again.
He "deserves" it because he shot you down. He drained your fuel tanks. There is such a thing as manuever kill, you know? You don't have to fire a shot to get a kill. Either he flew you into the ground with no damage because YOU messed up and were gaming the game to fly at 25% internal fuel,
or he shot you and put holes in your gas tank, making you run dry. Either way he earned the kill and force you out of the fight and onto the ground.
I'm not asking for nor do I want a instant repair or even more ammo just a fuel boost.
No, you just want instant do-overs. Your sortie is over. You lost. You have infinite tries. So just try again. It's not about how hard it would be to implement, IMO. It's the basic underlying principle of the matter. You were beat. You went into a fight and came out on the bottom end of the winning spectrum. Why should you deny the other player his/her well-earned kill? It's petty and it's like a toddler stamping his feet for a cookie before dinner (or fill in whatever selfish analogy here).
The ONLY function this would serve is to aid griefers and weak pilots that can't fly anything in a fight unless it has almost no gas onboard. The solution to 1 is an attitude adjustment. The solution to 2 is skill based and requires, simply, "more practice."
EDIT: Note that neither of those solutions involve changing the game...
