Aero Dancing 4: New Generation Cheats :
To get your speed to Mach 2.0
To get your maximum speed record to Mach 2.0, enter Free Flight and use the F-104 (Drone) on the ''Bay'' stage. Once airborne, land your plane on the long freeway that is along the coast line. Then, light your afterburners and keep your left analog stick fully pushed up. If done correctly, your plane should overspeed exactly at Mach 2.0!
