December 17, 1915 – The First flight of The Handley Page Type O which was an early biplane bomber used by Britain during the First World War. At the time, it was the largest aircraft that had been built in the UK and one of the largest in the world. It was built in two major versions, the Handley Page O/100 (H.P.11) and Handley Page O/400 (H.P.12). The impression made by the Type O was such that for many years after the war, any large aircraft came to be called a “Handley Page” in Britain and entered the dictionary as such. The design of the series of aircraft began shortly after the outbreak of the First World War as a result of meetings between the Royal Navy’s Director of the Air Department, Captain Murray Sueter and Frederick Handley Page. Sueter requested “a bloody paralyser of an aircraft” for long-range bombing.
