A dense, but fact-filled book that talks about the critical years between World War I and World War II, as the US military sought to evolve airpower from fringe element in the arsenal into a significant part of American warfighting. It is a tale about the lives and actions of the key leaders, from Billy Mitchell and Hap Arnold to emerging officers like Curtis LeMay. As the leaders of the fledgling service, they not only had to prepare to fight the next war, developing tactics and technology, but they also had to fight the political battles for relevance, countering the Navy and those who did not feel the way about Air Power like they did. Of note, the Air Corps was being driving not as much by Generals, although Mitchell, Andrews and Arnold did achieve that rank during the timeframe, but by Majors, Lt Colonels, Captains, and Lieutenants, the lower-level, but no less important, leaders that any military requires for success. Some of the accounts can get bogged down in minutia and technical terminology, but for any military officer, especially in the Air Force, this work is worth the time, probably in the earlier officer ranks.
