The site northwest of Chicago had been home to a Douglas aircraft assembly plant during World War II, and in 1945 the city selected it for development as a new airport. Its identifier, ORD, came from the Orchard Field name. In 1949, the airport was renamed for Lieutenant Commander Edward “Butch” O’Hare, the U.S. Navy fighter pilot and Medal of Honor recipient who was lost in combat during World War II.² https://www.forces-of-flight-aviationhistory.com/blog/not-a-screw monthly 0.5 2026-09-12 https://images.squarespace-cdn.com/content/v1/692f43705e13f51507346b41/1789242056977-T34SNR5DQKS74JGLYDPZ/unnamed+%283%29.jpg Articles and Insights from Forces of Flight - Not a Screw - Make it stand out Original propeller from the 1903 Wright Flyer, 1903.
