The Handley Page Type O was a biplane bomber used by Britain during the First World War. When built, the Type O was one of the largest aircraft in the world. There were two main variants, the Handley Page O/100 (H.P.11) and the Handley Page O/400 (H.P.12).

The aircraft were used in France for tactical night attacks on targets in German-occupied France and Belgium and for strategic bombing of industrial and transport targets in the Rhineland. Some aircraft were temporarily diverted to anti-submarine reconnaissance and bombing in the Tees estuary in 1917 and two aircraft operated in the eastern Mediterranean. The Type O made such an impression that for many years after the war any large aircraft in Britain was referred to as a "Handley Page", even getting a dictionary entry.^[1]
