Billy Barker was an Ace pilot in The First World War for the allied forces. An ace pilot is a pilot in the war that shoots down a certain amount of Enemy Planes. He was 35 years of age at the time of the war. As an "Ace" in his career he shot down 20+ enemy planes (by + I mean more like 25-28 Kills and that is a lot if you think about it right? Just think of 26 planes sitting on the ground side-by-side that is how many 1 plane shot down.
