Written note on inside cover. This book describes over 170 types of gliders, drawn from 19 nations, embracing historic pre-war gliders as well as a number of experimental 'one-off' and home-built designs. It also includes a number of motor gliders, a breed of aircraft that has evolved through the need to dispense with the ground-crew and launching aids necessary for conventional glider operations. Each entry consists of short description, table of data and both a specifically-prepared three-view drawing and a photograph.
