Records for the precursors of the RAF, the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS), are held at The National Archives, as are RAF records for service during the First World War. These cover service records of RAF Officers that served prior to 1922 (AIR76) and Airmen that served prior to 1924 (AIR79). Records of RFC officers, 1914-March 1918, were forwarded to the RAF and are in AIR76. Records of RNAS officers, 1914-March 1918, are in ADM273. After March 1918, look in AIR76.
If the airman died or was discharged from the RFC before April 1918, look in WO363 or WO364. If the airman served in the RNAS before April 1918, his record of service up to 31 March 1918 will be found in ADM188. If he served after April 1918, his record was kept from then on by the RAF. Records of the first 329,000 men who served in the RFC before 1 April 1918, and in the RAF (formerly RFC and RNAS) from 1 April 1918 are in AIR79. Records of those men within the service number range 1-329000 who went on to see service in the Second World War and records of men whose service number was 329001 or higher, are still maintained by the RAF.
