The Airco DH.9 (designed by Geoffrey de Havilland) was a basically good design, spoilt by a poor engine. When the American V-12 Liberty #engine was fitted towards the end of WW1, it transformed the #aircraft, and it served into the 1920s. #RAF #WW1 #biplane #RAFMuseum #museum #warplane #bomber #aviation #aeroengine
