5th Edition 1954. A newly revised edition. Includes an original photograph of Neville Duke. Flat signed and a presentation inscription from Neville Duke. This book, by a famous test pilot and WW2 fighter pilot and by an ex-bomber navigator, was written primarily for the aviation enthusiast with little technical knowledge of flight. The information it provides, however, was drawn from all the leading aircraft and aircraft-engine manufacturers in Britain in 1953 and covered the very latest developments in high-speed aircraft design and construction. Book is very good++ and bright. Contents good. The wrapper is very good and bright. Edges rubbed, creased and nicked. A few closed tears to edges. Small loss to spine tips.
