During the first 10 months of the war in the Pacific, Japan achieved air supremacy with its carrier and land-based forces. But after major setbacks at Midway and Guadalcanal, the empire's expansion stalled, in part due to flaws in aircraft design, strategy and command. This book offers a fresh analysis of the air war in the Pacific during the early phases of World War II. Details are included from two expeditions conducted by the author that reveal the location of an American pilot missing in the Philippines since 1942 and clear up a controversial account involving famed Japanese ace Saburo Sakai and U.S. Navy pilot James and "Pug and " Southerland.
