For military aircraft, historical overviews are offered by John W.R. Taylor (ed.), The Lore of Flight (1970, reissued 1986), a technically informed and well-illustrated work with separate sections on history, structures, engines, equipment, and flying, and containing an encyclopaedic index; and David Brown, Christopher Shores, and Kenneth Macksey, The Guinness History of Air Warfare (1976), a concise compilation of salient events and developments. Aircraft design is covered in John D. Anderson, Jr., Introduction to Flight, 3rd ed. (1989), an engineering overview of aircraft design and performance at a basic level, incorporating a technically accurate history of manned flight; and Edward H. Heinemann, Rosario Rausa, and K.E. Van Every, Aircraft Design (1985), a study of contemporary theory and practice. Aircraft propulsion is covered in Herschel Smith, Aircraft Piston Engines (1981), a technically informed history of power plants from the Wright era to the years immediately after World War II; and Edward W. Constant II, The Origins of the Turbojet Revolution (1980), a scholarly history of the development of turbojet engines. For early military aircraft, see Richard P. Hallion, Rise of the Fighter Aircraft, 1914–18 (1984), a technologically and tactically informed account; and John H. Morrow, Jr., German Air Power in World War I (1982), an account stressing interactions between strategy and tactics on the one hand and social and economic factors on the other. Eric M. Brown, Duels in the Sky: World War II Naval Aircraft in Combat (1988), is an analysis of combat capabilities, based on personal experience, by a military test pilot. Robert L. Shaw, Fighter Combat, 2nd ed. (1988), focuses on modern jet aircraft but incorporates a solid historical base. R.A. Mason and John W.R. Taylor, Aircraft, Strategy, and Operations of the Soviet Air Force (1986), covers the development of military aeronautics in the former Soviet Union. Marshall L. Michel III, Clashes: Air Combat over North Vietnam, 1965–1972 (1997), covers the technical and tactical aspects of the most hotly contested air war of the second half of the 20th century. For treatments of radar-evading aircraft, see Doug Richardson, Stealth Warplanes (1989; also published as Stealth), a review of the origins of stealth technology with informed speculation on contemporary and future developments. Two books that cover unmanned aerial vehicles are Bill Yenne, Birds of Prey: Predators, Reapers, and America’s Newest UAVs in Combat (2010), a technical and historical overview; and P.W. Singer, Wired for War: The Robotics Revolution and Conflict in the Twenty-first Century (2009), a more critical look at the policy of remote-control warfare.
