The development of aviation inevitable included not only breakthrough moments of genius but also blind alleys, some of them deadly. Manned flight was bound to attract the attentions of the photographer, the exponent of a science which was itself in its infancy, and this collection of photographs explores the failures as well as the triumphs. X-Planes offers insights into aviation research development unavailable anywhere else -- there will be something new even for the expert.
