Early in the Pacific War in WWII the Grumman F4F Wildcat was the best fighter aircraft the U.S. had but was out performed by the Japanese Zero. On February 20, 1942 LTCDR Edward Henry “Butch” O’Hare became the United States Navy's first Ace and two months later was awarded the Medal of Honor, the first WWII USN pilot to do so. On the night of November 26, 1943 O’Hare was shot down and was never found. He was awarded the Navy Cross posthumously. In his honor a USN destroyer and Chicago’s Orchard Depot Airport were named O’Hare.
