Would it be possible to introduce a system which 'turns off' the ability to be awarded damage to critically damaged aircraft?
For example... You take the wing off a bomber.... no chance of further controlled flight... and a lovely...... 'person' on your country follows this flaming wreck down, spraying, resulting in them being awarded the kill on an already critically damaged aircraft.
Perhaps when critical damage is registered, the ability to be awarded anything greater than an assist is turned off?
Perhaps allow people to take the rest of wing off of a tip'd and flaming buff in order to take them out before they can suicide bomb hangars/CVs... but award them with an assist.
All superficial damage would still be counted as always.... whoever does the most damage before an un-flyable state is reached counts... but once that 'flyable' threshold is crossed..... cut the ability to be awarded a kill.
I suspect that this idea has been raised before.... but it is a good one.
And think of how funny it would be to see those knobs who habitually follow other's kills down in order to steal the kill do so.... waste all their ammo, blow all their alt (and possibly auger

) only for them to be awarded an assist for their 'trouble'.

[Edit]
Also, I wonder if it would be worth considering changing how kills are awarded in the following case:
A target is hit quite hard by 'Aircraft A' with a 6 x .50 cal load out... yet the aircraft is still in a flyable condition and is no longer engaged with the intial attacker.... the battle rages on....
'Aircraft B', a countrymen of 'Aircraft A' encounters the target and engages. 'Aircraft B' gains the advantage and takes a shot with 30mm cannon which would destroy any aircraft, fresh out of the hangar or otherwise.
It seems to me that breaking an aircraft in two is more worthy of being awarded a kill than making swiss cheese of non-vital surfaces.
Perhaps change the system so that a catastrophic hit on a flyable aircraft gets the kill.
The way I understand it, the damage model works like this:
Each aircraft has a 'damage allocation', let us say 100 points of damage, 10 points of damage being a couple of bullet holes in non-critical areas, 100 being destruction.
If Aircraft A inflicts 55 points of damage on a target and Aircraft B inflicts 95 points of damage... only the first 45 points a counted and thus even with a 'kill-shot' from Aircraft B, Aircraft A is awarded the kill.
I'm too tired to go into this further right now.... anyone have any further thoughts or contributions to this idea?
