This second volume in German Great War flyer Haupt Heydemarck's trilogy of aerial memoirs gives us all the hazards and hopes of his job as an aerial observer written with humour and panache. The book is illustrated with many photographs - several taken by the author himself as part of his observation duties. Heydemarck's jaunty style is written against a background of bleakness: the mortality rate among his comrades was phenomenally high.
