X-Plane 9 And 10 M-53 - Soviet SST. This plane was a Vladimir Mayasischev design (1950s) and only existed on pen and paper. Unfortunatley, it never made it further along the line, due to resources not being strong enough. Some of the M-53's features include: high res textures, LIT textures, almost fully customised cockpit, hi res outer cockpit window, custom sounds and five liveries (modern and old Aeroflot, white, silver, and experimental). Please read the included documentation on how to get the most enjoyment from this amazing aircraft. By Hamish Hall-Smith.
