D.H.66 Hercules
The de Havilland DH.66 Hercules was a British 1920s seven-passenger, trimotor airliner built by de Havilland Aircraft Company. With the Hercules, Imperial Airways took over responsibility for the airmail service from the Royal Air Force, which had been operating the obsolete Airco DH.10 Amiens. The Hercules effectively provided long-distance service to far-flung regions for Imperial Airways. Although slow, they pointed the way for future airliners.
