More than 150 never before published illustrations, complimented by an exhaustively researched text, document the little-known air war between Bolivia and Paraguay during the late 1920s and early 1930s. Full details of such aircraft as Fiat C.R. 20s, Curtiss Hawk IIs, Curtiss Ospreys, Potez 25s and all other types employed by both combatants, including acquisition, operations, and markings make this a must for historians, modelers, and anyone interested in golden-age aviation.

The North American O-47 is an American observation fixed-wing aircraft monoplane used by the United States Army Air Corps. Book describes in the great detail the development history and service history of this overlooked aircraft. Many unpublished photos, color profiles and scale plans complete the story.

This book examines the genesis of the AT-9 design, its competitors and, eventually, comrades-in-arms, with whom AT-9s were always literally the best and the brightest, and looks at the fielding of the aircraft to the 24 initial stations as well as an astonishing number of unusual and special assignments – including assignment to line, tactical units. After producing 791 aircraft between September 1941 and January 31, 1943, and assigning every single one of them, and having served actively and continuously through to VJ-Day, exactly one complete AT-9 survives, and this solitary example is actually a composite of several aircraft.

Heralded by Brazilians as the 'Father of Flight', Alberto Santos-Dumont made the first of several spectacular flights in his lighter-than-air dirigible in France in 1901, two years before the Wright brothers' first fixed-wing flight in North Carolina. Though they are often overlooked, Santos-Dumont and others in Latin America played a key role in the development of aviation. This generously illustrated book tells their story. Written to complement the Smithsonian Institution's National Air and Space Museum's new permanent exhibit, America by Air, ""Conquistadors of the Sky"" celebrates the aviation achievements of twenty-one Latin American nations over the last 100 years - making this chronicle of heroic ventures and epic flights the best reference available on the subject.
