Though we are still within the first century of powered flight, air power has already become the dominant form of military power projection in the modern world. The doctrinal underpinnings of air power thought are, of course, traditionally ascribed to the three great theorists of air power application, Douhet, Trenchard, and Mitchell. Since the Second World War, the air power community has not often explored the doctrinal implications of air power development. Lord Tedder's Lee Knowles lectures at Cambridge, and the writings of Air Vice Marshal R. A. Mason, and Colonel John A. Warden constitute notable-and noteworthy-exceptions. Now comes Colonel Phillip Meilinger, who has posited a group of provocative propositions that will instill an appreciation for air power for those who seek to understand it and challenge the assumptions of those who do not yet appreciate what it offers. This book has been deliberately designed in a small format so that it can be readily carried in the pocket of a flight suit or a BDU. Readers are encouraged to discuss these propositions and, if so moved, to communicate directly with Colonel Meilinger via the School of Advanced Airpower Studies, Maxwell AFB, Alabama, or through the Office of the Air Force Historian, Bolling AFB, Washington, D.C.
