I first heard this story on Paul Harvey years ago., and I've retold it in part but never in full. This is the story of Lieutenant Commander Edward Henry O'Hare (March 13, 1914 – November 26, 1943) who was an American naval aviator of the United States Navy, who on February 20, 1942, became the Navy's first fighter ace of the war when he single-handedly attacked a formation of nine Japanese medium bombers approaching his aircraft carrier. Even though he had a limited amount of ammunition, he was credited with shooting down five enemy bombers and became the first naval aviator recipient of the Medal of Honor in World War II. 

Butch's father had been the attorney for gangster Al Capone for years and at some point had agreed to go undercover for the US Treasury Service in order to expose Capone for tax evasion- the spoken legend being that Eddie (EJ), Butch;'s father, knew that by testifying to Capone's dirty dealings he would be putting a target on his own back, and agreed to give up Capone in exchange for the promise that Butch could attend  the US Naval Academy. EJ testified, Capone went to prison, and in revenge, as the legend (most likely true) goes, EJ was shot and killed while driving to work. 

On September 19, 1949, the Chicago-area Orchard Field Airport was renamed O'Hare International Airport, sin honor of Butch o'Hare.. An F4F Wildcat, in a livery identical to the aircraft ("White F-15") flown by O'Hare, is on display in Terminal 2. The display was formally opened on the seventy-fifth anniversary of his Medal of Honor flight
