The 95th Aero Squadron was the first American pursuit squadron to fly over the front in March 1918 and 1st Lt. Waldo Heinrichs was one of its original members. The history of the Squadron is told through the words of those who served, Heinrichs' richly written diary forms the nucleus of the story supported by contemporary letters, anecdotes, and combat reports from many of the other flyers. Entries from the official Squadron history as contained in the History of the American Air Services A.E.F. (the Gorrell History) round out the narrative. Over 280 photos, most unpublished from the personal albums of the participants, show planes, places and personnel which surrounded this happy band of warriors.
