World War I was the first war in which aviators played a part. What was it really like to manoeuvre the first aircraft in battle? How did aerial strategy and tactics evolve throughout the war? And what about the amazing development of aeronautical technology within a few short years? Using rarely-seen archival footage, Aces chronicles the wartime career of a Canadian airman, providing a first-hand glimpse of the war, which broke out just 11 years after the Wright brothers pioneered the flying machine.
