Totally agree as I loath plane rammers. It would also make sense considering that a falling piece of fusillade from a plane you’ve just killed can destroy you.
It should depend on where you hit it nad with what. The one ramming should definitely get destroyed most of the time since they go in with their nose but if they only hit a wing, it’s only that wing that should be damaged.
Easy fix: make the blast of a plane that got destroyed to pack a real punch that can destroy other planes that are too close.
This would also give some use for the planes are suicide missiles at ground enemies
