This volume is the fifth of the Aviolibri Series. With the precious collaboration of his collector friends and the support provided by the Aeronautica Militare, the author has been able to bring some light on this little known field of flight helmets of the Regia Aeronauticain Second World War. The text, including captions, is offered both in Italian and English, and deals with all aspects of the massive number of different helmets illustrated. Photographs are 45 in colour and 19 black and white.
