During the IRT in a Victor SR2 we were required to do Max Rate Turns at 50,000. Limiting Mach number was recognised by a light buffet, pre stall buffet similarly. The gap between those two at 50,000 ft was 18 kts. Max angle of bank achievable was 15
degrees. I understand that the gap between those speeds in a U2 at its max altitude was a mere 2 kts. Flying with finesse!
