Somebody said - "Because you'll probably exceed Mach Crit." - I hope that you DO exceed Mcrit at higher levels, that's where Normal operation for Jet aircraft occur (Especially Maximum Range Cruise).
Can you tell me one airline or commercial aircraft which flies above Mcrit as normal operation ?
As soon as you hit Mcrit shock wave will develop which will significantly increase drag. Are you telling me that max range will increase ?????
