AIRCRAFT of the UNITED STATES, VOLUME ONE
R.A. Saville - Sneath ( 1895 - 1989 ) was born in Sheffield ( South Yorkshire, England ).
He served in the First World War as R.E. " Signals " motor - cyclist dispatch rider. When he later became chairman of companies concerned with aircraft equipment and international patent development, his professional interests kept him in close touch with the trend of aircraft design after the First World War.
In July 1938, R.A. Saville - Sneath was appointed Head Observer at a local post of the Observer Corps, at that time a branch of the Special Constabulary. Although familiar as an amateur pilot with many types of aircraft, he found aircraft recognition to be a growing problem, requiring serious study and methodical instruction.
He gave many lectures on aircraft recognition and was an honorary instructor and librarian for the Hearkers' Clubs. He contributed articles on the subject to the Daily Mail, the Daily Mirror, the Aeroplane Spotter, Practical Mechanics and other journals. R.A. Saville - Sneath was also the author of Britain's Airpower.
