"One particularly interesting kill was scored by a Marine Lieutenant R. R. Klingman of VMF-312 Checkerboards, over Okinawa. Klingman was in pursuit of a Kawasaki Ki-45 Toryu ("Nick") twin engine fighter at extremely high altitude when his guns jammed due to the gun lubrication thickening from the extreme cold. He simply flew up and chopped off the Ki-45's tail with the big propeller of the Corsair. Despite missing five inches (127 mm) off the end of his propeller blades, he managed to land safely after this ramming attack. He was awarded the Navy Cross."
