The Sikorsky XR-4 Hoverfly, the prototype of the world’s first production helicopter and the only US helicopter to see action in World War II, is officially accepted by the Army Air Forces at Wright Field, Ohio. Company pilot C.L. “Les” Morris had flown the prototype 761 miles from the Stratford, Conn., factory to Wright Field in five days and 16 flights, and Igor Sikorsky was the passenger on the last hop from Springfield, Ohio, to the base. They were met by Orville Wright when they arrived.
