This is one of the battle which still have to be confirmed and this is happen, if this happen, over Germany, when two P-51 attack sole Kozedub and after attempt to escape from fight, he was forced to fight back and shoot down both Mustang. First one was killed while another pilot, Negro, survived and report that he was shoot down by red nosed Focke Wulf.
But no matter of that, there is many occasions where the friendly airplanes was under attack, just to remind combat in South Serbia when US fighters attack Soviet airplanes as well combat where British Typhoons attack their own Meteors!
