X-Plane 9 And 10 Miles M.52. The Miles M. 52 was a turbojet powered supersonic research aircraft project designed in the United Kingdom in the mid-1940s. Design work was undertaken in secrecy between 1942 and 1945. This file includes X-Plane 9.70 (main) and X-Plane 10.36 (additional) .acf files. You will need to overwrite the X-Plane 9 .acf file with the XP-10 version of the .acf file for that file to work (not a stand alone version). Four liveries are available: default silver (metal), yellow, blue and camouflage. Documentation includes the history of the aircraft, flying tips and credits. By Graham Algeo.
