Percy F. Westerman 
Billy Barcroft, R.N.A.S. [EPUB ebook] 
A Story of the Great War

One key factor that differentiated World War I from all of the military conflicts that had gone before it was the widespread use of aircraft in battle. Acclaimed action-adventure novelist Percy F. Westerman takes advantage of this fact in Billy Barcroft, R.N.A.S., which recounts the thrilling wartime exploits of one intrepid WWI airman and his crew.
