Published in 2016, 'Sopwith Camel 1916-20 (F.1/2F.1)' is a novelty Haynes Owners' Workshop Manual devoted to the famous WW1 fighter aircraft, the Sopwith Camel. The historical detail segment is surprisingly brief, and even then devotes itself more to the formation of the early RFC than to the Camel. The technical detail that follows is amazing, and makes use of some of the best airworthy Sopwith Camel replicas for the walkaround detail. I did expect great things of the section dealing with the rotary engine, but found that I didn't understand a word of it and will have to go elsewhere for that detail because I was interested in knowing just how that technological cul-de-sac worked. This was made up for by the wealth of useful information that was imparted, and I recommend it to all aviation buffs.
