This is the second version of my SST 28. As i said in the SST 28 post this is a medium range 450 seater airliner capable of reaching speed highter then mach 3 (3750 km/h). The aircraft is close to his brother only by the fuselage that got just some adjustments. The main change is the wing that become a variable sweep wing (similar to the one on the Boeing 2707) and to control the sweep you can use the trim lever (P.S. at max speed take the sweep to a maximum of +50% because the wing risk to sweep back too much). For the rest the plane has very similar sistems to the first model (AG1= landing lights, throttle= subsonic mode, throttle0+AG2=supersonic mode)
