No information is available for Tone for about 19 months – from the last record of him flying at London Aerodrome in September 1913 to him joining the Royal Flying Corps in April 1915. His Service record card (AIR/76/29) doesn’t refer to any occupational activity during this period. At his pre-enlistment medical his occupation is recorded as aviator and aero-engineer and so possibly he found some work at Hendon Aerodrome or he may simply have been doing casual work, while living at home with his parents in Eastcote, of a type that he didn’t consider had any relevance to a flying career and so wasn’t worth mentioning in his application to the RFC?
