I heard about this book from a friend and requested a copy from the library. It wasn't yet in my local library system, but they found one for me (librarians are wonderful people) and I read it straight through.
I was a USAF fighter pilot from 1973 to 1997. Samuel Hynes flew fighters for the Marine Corps from 1943 to 1953. The Unsubstantial Air is about the first American fighter pilots, the young men who flew with the British and French ... and later on, the USA ... during the Great War. You can safely assume I was enthralled by Hynes' book.
Using wartime diaries, letters, telegrams, newspaper articles, and personal recollections of surviving early aviators, Hynes traces the fascination of young American men with the idea of flying; the establishment of college flying clubs in the USA; the early days of Americans heading off to England and France to play a role in the momentous war in Europe. He follows the paths of the first volunteers, who generally started off as French Foreign Legionnaires or ambulance drivers and then gravitated to aviation. He recounts the beginnings of wartime flying training in the USA, the way young men with minimal flight training were transported to England and France, the building of training airfields overseas and the different ways men were taught to fly by the French and British. He follows key figures (Quentin Roosevelt, son of Teddy, for one; Billy Mitchell for another), who organized and oversaw American flight training in France in preparation for the USA's eventual entry into the war.
All of this, and particularly the chapters describing actual combat over the front lines, is riveting reading, but what most fascinated me was discovering how little the essentials have changed. What attracted the first young men to flying in combat ... the romantic idea of one-on-one combat, of being a knight of the air ... is what attracts young men and women today. The desire to be above all things a chasse pilot (a pursuit pilot, or as we call them today, a fighter pilot, sent aloft to shoot down enemy aircraft), as opposed to a "mere" observation or bomber pilot ... that too appears to be eternal.
No one knew how to conduct aerial combat in the beginning. They learned quickly: how to conduct aerial gunnery, how to strafe and bomb, how to provide mutual support to other pilots; the fundamentals every fighter pilot today must master. The life fighter pilots lived, the independence and spirited parties and drinking and whoring, the eagerness to take off at dawn to confront the Boche, the shock of a comrade's sudden death ... well, it's the life Samuel Hynes lived in WWII and Korea; it's the life I lived in F-15 squadrons during the Cold War and Desert Storm.
This really is a fabulous history of the beginnings of aviation and air power in wartime (as an aside, it's taken us almost a hundred years, but the vision of air power pioneers like Billy Mitchell, which is powerfully spelled out in Hynes' history, have finally become reality with improved aircraft, better command and control, and smart weapons). If you're at all interested in military aviation, The Unsubstantial Air is essential reading.
