1945, Marine pilot Bob Klingman used the propeller of his F4U Corsair to chop off the tail of a Japanese reconnaissance plane. Because his guns had frozen due to the high altitude, he turned his fighter into a buzzsaw to down the enemy. He then managed to fly back to base even though 6" had broken off one propeller blade while the other two blades were bent back. Chunks of the Japanese plane were also stuck in the Corsair's engine cowling. Klingman was awarded the Navy Cross and the Air Medal with Gold Star
