The book, Shorts Aircraft Since 1900, traces the history of aircraft designers Eustace and Oswald Short from their first spherical balloons, to the Aero Club, to their rigid airships built in World War I, to the development of metal hulled flying boats, to World War II bombers up through post World War II aircraft.  The Short brothers early on became suppliers to the Royal Navy and made notable contributions in the technical areas of deck launching, aircraft folding-wings, buoyancy bags and sprung floats.  Oswald Short's pioneering work on metal hulled flying boats is described in detail along with their operational histories.  In this latest edition of the book Shorts Aircraft Since 1900, the section on unbuilt projects has been expanded and the post World War II story of Rochester's last days and Northern Ireland's new industry has been updated through to the late 1980s.  Chapters on the Skyvan, Belfast, 330, Sherpa and 360 have all been updated and notes have been added for the new Tucano training aircraft.  The book, Shorts Aircraft Since 1900 includes the following major sections: 1) Forward; 2) The First Torpedo Drop; 3) Origin and History of the Company; 4) Short-Wright Biplanes; 5) Short No. 1; 6) Short No. 2; 7) Short No. 3; 8) Pusher Biplanes (1910-14); 9) Twin-engined Biplanes (1911-13); 10) Early Short Monoplanes; 11) Tractor Biplanes; 12) Tractor Seaplanes; 13) Types 166, 827 and 930; 14) Type 184; 15) Bomber (1915-16); 16) 310 hp Seaplanes (1916-19); 17) Experimental Scouts N.2A and N.2B; 18) Shirl; 19) Cromarty; 20) Sporting Type Seaplane; 21) Silver Streak; 22) Springbok; 23) Gnosspelius Gull; 24) Cockle and Satellite; 25) Mussel; 26) Singapore I; 27) Chamois, Sturgeon and Gurnard; 28) Crusader; 29) Calcutta; 30) Rangoon; 31) Valetta; 32) Singapore II and III; 33)   Sarafand; 34) Kawanishi K.
