Captain William Otway Boger was a World War I flying ace credited with five victories. Boger served in Strathcona's Horse from August 1914 through September 1916. After transfer to the Royal Flying Corps, he served as an observer/gunner for No. 11 Squadron RAF in FE.2bs. He was wounded in combat two days before Christmas, 1917. He trained as a pilot and joined No. 56 Squadron, which was equipped with Royal Aircraft Factory SE.5as, on 24 May 1918. He scored his first victory on 13 June 1918, and rounded off his string with his fifth, on 8 August 1918. He failed to return from patrol on 10 August 1918. German ace Josef Veltjens claimed a kill on a SE.5a at 1245 that same day, and is usually considered the victor over Boger.
