I have had the Xtreme Prototypes X-15's well over 250,000 feet and to nearly Mach 4. Aerodynamic controls stop working at that altitude and FSX does not model for control thrusters. One must plan a gradual pitch over to maintain angle of attack going over the top of the climb. But it works. Great view too.
