this aircraft is designed as an experimential hypersonic aircraft. it's swept wings and powerfull engines allow for it to reach a top speed of mach ?4.282163?. however due to it's extreme amount of sweep angle on the wings the unpowered glide slope of this aircraft is very steep. be cause of this landing can be a challenge. the recommended landing speed is anywhere from 500mph to 600mph any lower speed approaches than 500 mph will not have enough lift to safely bring the plane down and will result in a crash. due to the high landing speed this aircraft has been equipped with parachutes to stop on the runway quickly on action group 4. just don't deploy them in mid air becuse the g forces from the sudden decelleration will rip the plane apart.
