The Armstrong Whitworth Atlas was a British single-engine two-seat biplane. It served as an army co-operation aircraft for the Royal Canadian Air Force in the 1920s and 1930s. It was the first purpose-designed aircraft of the type to serve with the RAF. The prototype was first flown on 10 May 1925. The production Atlas had a steel tube fuselage with fabric covering with single-bay swept metal wings. It could be fitted with a hook under the fuselage to pick up messages and could carry a 460 lb (210 kg) bombload under the wings. The Atlas continued in service in the army co-operations role until replaced with the Hawker Audax in 1935. Harold Skaarup web pages
