Kay:
The Galloway "Adriatic" 230 hp 6 cylinder-in line engine and the 200 hp Siddeley-Deasy "Puma" were production versions of the 300hp B.H.P. engine that the Air Board put into mass production. The problem arose when Siddeley-Deasy and Galloway made changes in the B.H.P. engine to meet the needs of mass production. This turned out to be a disaster to the D.H.9 program which was to replace the D.H.4 as a 1918 day bomber. To quote Jack Bruce, "The D.H.9 was, in short, a good aeroplane spoiled by a bad engine......"
