Book excerpt: Starting in 1909 with the beginnings of military aviation and the aviation industry and ending with their catastrophic postwar contraction, the book examines the totality of the air war: its heroism, romantic myths, politics, strategies, and cost in men and materiel. John H. Morrow, Jr., also elaborates on the advancements in aircraft and engine technology and production during airpower's development into a viable and threatening military weapon within a decade of its origins.
