London in 1938, and was in the
British Army as a territorial volunteer from 1939 to 1946. He spent a year in
Iceland, training for mountain and
Arctic warfare, and drove his machine-gun carrier on to the beach in

Ministry of Civil Aviation,
British European Airways, the Bristol Aeroplane Company and

United States in 1968 to lead market research for
Douglas Aircraft. A lifelong
aviation enthusiast, Davies dedicated his work to different aspects of the airline industry, including traffic forecasting, and specializing in its history. He researched airlines at the
National Air and Space Museum as the
Charles A. Lindbergh Chair in Aerospace History in 1981–1982. Davies was responsible, alongside artist

An Airline and its Aircraft, about selected airlines' histories, including the types flown. His writing led him to found
Paladwr Press, which published 38 books of classic airline histories and biographies. Well travelled to more than a hundred countries, Davies was a member of three
British Royal Societies, the
Explorers Club, and others in France and Brazil. He enjoyed a 30-year career as the Curator of Air Transport at the
