The de Havilland DH.66 Hercules was a 1920s British seven-passenger three-engined airliner built by De Havilland Aircraft Company at Stag Lane Aerodrome. As a more modern replacement for the D.H.10s used on the RAF's air-mail service Imperial Airways used the Hercules effectively to provide long-distance service to far-flung regions. Although the giant airliners were slow and cumbersome they pointed the way for airliners in the future.
Made by De Havilland.
