Supercruise
[edit]Every wiki and publication I see defines supercruise as the ability to exceed and sustain speeds greater than MACH 1 without the use of afterburners, this is false , The ATF program which led to the F-22 clearly defined supercruise as the ability to fly at and sustain speeds greater than MACH 1.5 without the use of afterburner.
