Dunne D.III Biplane

The D.1 proved the soundness of Dunne's ideas and was followed by further machines on the same principle; the D.3 was constructed at Farnborough and later ones built privately at Eastchurch. In addition, both seaplane and flying-boat versions of the Dunne biplane were built in America by the Burgess Company. But it gradually became apparent that inherent stability was not so essential for a military aircraft as good manoeuvrability.
