Parent subjectBritish aircraft (WW1 period)
Description Built by the firm A. V. Roe, the 504 was a two-seater multi-purpose biplane, first produced in 1913. Stable and easy to fly, the 504 was used by the Royal Flying Corps during the period 1914-15 in reconnaissance and light bombing roles. Its average performance meant that by 1915 it was obsolete as a front-line combat aircraft, but it was used subsequently as a very successful training aircraft.
