Bristol Boxkite by Ivan Berryman. (AP)

Based on a design by Henry Farman, the Bristol Boxkite first appeared in 1910 and was put into service with the RFC from its formation in 1912. It was used extensively by RNAS training schools at Eastbourne, Eastchurch and Hendon, but the type was withdrawn from service in 1915 due to obsolescence. Military versions were distinguishable from production aircraft by having extended upper wings to increase lift under load, as depicted here.
