Orchard Field-Douglas (ORD) was renamed in 1949 after Lt. Cmdr. Edward "Butch" O'Hare, a World War II flying ace who was awarded the Medal Of Honor(sic). The first passenger service commenced in 1955, and the International Terminal was completed in 1958. When Midway Airport's domestic traffic was transferred in 1962, Chicago's O'Hare airport instantly became one of the world's busiest airport. Over to you.
