Query: NOT JUST THE HINDENBURG

This is one of a relatively few books covering the aviation history of the dirigible, or rigid airship. In the last century it was pioneered by the Germans, then experimented with by other nations. It ended with the Germans as well when the Hindenburg exploded in front of newsreel cameras. Most books look only at the Hindenburg disaster, ignoring the crashes of the R101, Akron, Shenandoah and others. Toland tells the story of them all, including accounts of ten disasters. It will soon become clear to any reader that the airship had more 'tragedy' than 'triumph' of course. It is a wonder they lasted as long as they did.The only fault I found with this book is that Toland devotes all his efforts to telling individual stories. These are necessary and interesting, but more attention could have been given to other aspects of the matter, such as parallel aviation developments or political events.
