And...

On 6th June 1943, Soviet pilot of 88IAP Alexander K. Gorovetz attacked a big group of the Stukas. His alone La-5 shot down 9 (nine!) Ju87s in single combat and forced all other bombers to chaotically drop bombs and to retreat. Ufortunately, he was out of ammo. And when four FW190s arrived, the hero was killed. So 9:1 during one mission is the world best score for a single fighter. These results were confirmed by ground troops which watched this bloody battle in the sky.
