Many books have been written about pilots of the Royal Flying Corps but the men on the ground, who kept the planes in the air and the guns firing, have been sadly neglected - and yet their role was a vital one. This truly remarkable book, the production of which must have seemed an impossible task, has more than remedied the situation. The authors have managed to locate all the non-commissioned airmen who enlisted in the RFC prior to the outbreak of war in August 1914, and for each one they have provided a mini-biography. The length of each entry varies, available records being what they are, but detail is provided for over 1,400 men. For those who became pilots, details of their certificates are given. Statistics include the establishment of the Corps at various times and there is a list of non-commissioned ranks as well as notes on uniforms, badges etc. There is a full record of works consulted at the Public Record Office and an excellent bibliography.
