EARLY in 1937 the Australian Government invited Mr. H. E. Wimperis to advise on the inauguration of aeronautical research in the Australian Commonwealth. It could have made no better choice. Mr. Wimperis has been closely connected with aeronautical research practically from its beginnings in Great Britain. For twelve years until he retired in 1937 he was responsible, as director of scientific research, for the organization and development of research in the Air Ministry. Owing to his retirement he was free to apply his unrivalled experience to the problems of Australia. He spent six months in visiting the Royal Australian Air Force Stations in New South Wales, Victoria, and Western Australia, and the civil aerodromes in New South Wales, Victoria, Western Australia and Brisbane. He also visited the Munitions Supply Establishment at Maribyrnong, Victoria, and many engineering and industrial plants.
