"One unique account was that of Lt. Alexi Khobistoff of the Red Air Force, who perfected an unusual method of destroying enemy aircraft when his plane's guns froze from ice build-up. With his sights set on a Heinkel 111, the distracted Khobistoff struggled to clear his guns when all of a sudden the prop of his plane tore through the bomber's wing. He managed to stay airborne while his target careened into the ground. He repeated this act a second time, but on this day it was intentional, cutting the rudder off of yet another German bomber. The third time and his fifth kill happened when a 109 mortally wounded his plane. Rather then go out quietly, the tenacious Khobistoff dove his plane into the nearest enemy fighter he saw, chewing its tail to bits. He bailed out and spent several weeks in the hospital, never to repeat his unorthodox tactic."
