One particularly unusual kill was scored by Marine Lieutenant R. R. Klingman of VMF-312 (the "Checkerboards") over Okinawa. Klingman was in pursuit of a Japanese twin-engine aircraft at high altitude when his guns jammed due to the gun lubrication thickening from the extreme cold. He flew up and chopped off the enemy's tail with the big propeller of the Corsair. Despite missing off the end of his propeller blades, he managed to land safely after this aerial ramming attack. He was awarded the Navy Cross.
