The Doak Model 16 (also called the Doak VZ-4DA) was the first tilt-rotor aircraft, using ducted fans driven by a turbine in the fuselage.  Its first flight was in 1958;  in 1973 it was transferred to the U.S. Army Transportation Museum at Fort Eustis, Virginia.  This aircraft was the only VZ-4DA built (serial #56-9642)  56-9642).  It was 9.75m long with a 7.75m wingspan (including the fans).
