DescriptionThe Douglas DC-5 (Douglas Commercial Model 5) was a 16-to-22-seat, twin-engine propeller aircraft intended for shorter routes than the Douglas DC-3 or Douglas DC-4.
By the time it entered commercial service in 1940, many airlines were canceling orders for aircraft. Consequently, only five civilian DC-5s were built. With the Douglas Aircraft Company already converting to World War II military production, the DC-5 was soon overtaken by world events, although a limited number of military variants were produced.
The DC-5 was developed in 1938 as a 16-22 seat civilian airliner, designed to use either Pratt & Whitney R-1690 Hornet or Wright R-1820 Cyclone radial engines. It was the first airliner to combine shoulder wings and tricycle landing gear, a configuration that is still common in turboprop airliners and military transport aircraft, although the modern versions are actually high wing, as the structure sits atop the fuselage shell rather than intersecting a significant segment. The tricycle landing gear was innovative for transport airplanes. It provided better ground handling and better ground visibility for the pilots. The fuselage was about two feet above the ground, so loading of passengers and cargo was easier than aircraft with the then-standard conventional landing gear.
Three aircraft made their way to Australia where they were sold to the United States Army Air Forces (USAAF) and operated for the Allied Directorate of Air Transport (ADAT). Two were destroyed by the end of 1942, the other was transferred to Australian National Airways (ANA), which operated it throughout the war on behalf of ADAT. Read more on these aircraft here.
