As opposed to Douhet, who was not a pilot, Mecozzi served as a combat pilot in the war and was accomplished in both air to air fghting and in air to ground attacks. This experience left him not at all ahistorical about the efectiveness of anti-aircraft and the need for what are now termed tactical aircraft, not just bombers. Thus, Mecozzi dealt with tactics and specifc capa‐ bilities (and limitations) of aircraft, subjects that were of much less interest to Douhet. Because of his perspectives and ideas, Mecozzi deserves this separate chapter, and Hippler integrates well the areas in which he agreed and disagreed with Douhet. This chapter becomes probably the most important one of the book, as it investigates issues discussed at the time that remain unresolved or are still open to interpretation: division of target‐ ing authority between air and ground forces, val‐ ue of attacks on forces themselves or on their sup‐ porting industries, and the value of targeting civil‐ ian morale. The book concludes with an epilogue, in which the author examines the history of strate‐ gic bombing as defned by Douhet and similar the‐ orists in other countries. The chapter is a short
