28 PRO AIR 22/100, ‘Fighter Command Daily Casualties’. According to the daily statistics reported to the Air Ministry, from 1 July until 1 November 1940 Fighter Command lost 284 pilots killed on operations and 159 killed in non-operational situations. The discrepancy between the two figures is difficult to explain. Post-war calculations of total pilot casualties give a slightly higher figure of 458, most of whom died in combat. The number of genuinely accidental deaths has been calculated at somewhere between 30 and 50. The Air Ministry figures suggest that combat was defined more narrowly at the time, which may explain the difference between wartime and post-war statistics. In addition to the pilot deaths, more than 200 suffered serious injury.
