As usual, an immense amount of information and photographs has been crammed into a pocket sized volume. I am left with the impression that the RNAS (for whom the Pup was conceived) were much ahead of the RFC when it came to ordering aircraft, the latter’s choices being usually dictated by political considerations. Indeed, Sopwiths was considered by many to be a Naval Contractor! Although fairly quickly outclassed, the Pup was a much loved aircraft in its time, flown by nearly all the Aces, and this book does it justice.
