[F22-Raptor-2006]

its possible to hit mach 1, but not effectively, because you'd black-out instantly (almost atleast) when y pull up, and planes like the F22 fly a bit faster, so you'd be almst all the time blackout

so i'd say if y want a modern fighter, go find a diff game

Yeah good point, G suits aren't really modelled into this game. Also modern aircraft do not go past Mach 1.2 at low altitude, the only way they reach their top speed which for the F22 is Mach 2.25 is to fly at high altitude so that could be anything up to 65,000 ft....
