Sagitarius Rising by Cecil Lewis stand out for me.

He lied about his age in order to join the Royal Flying Corps in 1915 and served as a successful fighter pilot during the First World War. He is credited with victories over eight German planes, and he survived an encounter with the infamous "Red Baron" von Richtofen. He was awarded the Military Cross for his numerous actions performed at the Battle of the Somme in 1916. His memoirs of the air war, Sagitarius Rising (1936) are considered to be one of the finest of that era. Sequels documenting his later life included Sagittarius Surviving, All My Yesterdays, Farewell to Wings and Gemini to Joburg.
