Just asking if it would be possible for a SR-71 to be flyable in IL-2, specifically if the games engine could fly a plane past mach 3.
But, with the new edition of radar inside the game, the SR-71 could be used as radar by flying high over enemy terrority, letting the friendly aircraft get a fix on the enemy aircraft, and the enemy planes wont even know were the friendly fighters are (unless there getting info from ground radar, but still after they escape the range of ground radar, they have lost them)
