Major David N. Spires, USAF (ret.) is the author of: Beyond Horizons: A Half Century of Air Force Space Leadership; Air Power for Patton's Army: The XIX Tactical Air Command in the Second World War; and, Image and Reality: The Making of the German Officer, 1921-1933.

According to the book description of Air Power for Patton's Army: The XIX Tactical Air Command in the Second World War, “A case study of one air-ground team's experience with the theory and practice of tactical air power employed during the climactic World War II campaigns against the forces of Nazi Germany.”

According to a review of Beyond Horizons: A Half Century of Air Force Space Leadership, it “is a study of the United States Air Force in space. Of all the military services, the Air Force has been preeminently involved for the past fifty years in initiating, developing, and applying the technology of space-based systems in support of the nation's national security. Yet there has been no single-volume overview of the Air Force space story to serve as an introduction and guide for interested readers. This book tells the story of the origins and development of the United States Air Force's space program from its earliest beginnings in the post Second World War period to its emergence as a critical operational presence in the Persian Gulf War.”

According to a review of Image and Reality: The Making of the German Officer, 1921-1933, “This intelligent monograph fills a gap in our knowledge of the 100,000-man army alllowed the Germans by the Versailles settlement. Spires gives meticulous attention to the 4,000 officers of the Reichswehr, specifically their selection, training, posting, promotion, and dismissal. He shows that these internal concerns of the army often had direct bearing on the politics pursued by its leaders and helped define their counterproductive relationship to the German Republic. A military man himself, Spires is both critical and sympathetic.”
