This is a small book but it is jam packed with photographs... It is divided into 3 sections; non-rigid, semi-ridged, and rigid airships. It includes the envelope capacity, overall length, engines, disposable lift, and top speed. This book even has a bibliography so that the curious, like me, can go and get more detailed information on them... I highly recommend this book.

The book is full of superb period photos and the superb artwork of illustrators Tony Bryan and Giuseppe Raval really help bring to light the fragility and the look of these airships. In all, it makes for another fascinating read and one that I know will draw you into it as it did I.

Ian Castle provides a highly lucid explanation of the various types of dirigibles, covering not only the development and operational use of the nonrigid blimps during World War I, but also Britain's far less successful program for the construction of giant rigid airships... Castle's book is a must for World War I enthusiasts, focusing on an aspect of that conflict rarely covered anywhere else. It should prove equally indispensable to anyone interested in lighter-than-air technology.
