Grumman F4F Wildcat. Chicago's O'Hare airport is named after Navy F4F ace, Butch O'Hare. In 1942 O'Hare was in the only airborne fighter plane close to his fleet when a surprise attack came from Japanese bombers. Low on fuel, he shot down three enemy bombers so fast that all were falling toward the ocean at the same time. He immediately damaged two others. Now out of ammunition, he continued to make intimidating passes and startled the attackers to the point that they broke off and ran. His single-handed efforts likely saved the vital carrier USS Lexington and other support ships.
