Suprised never had this plane here. Please .. no politics on this one .. just the hardware
My aerospace buddies say this is pretty good performance for a 747 .. those who really know say its UNDERSTATED. Nobody says its a Mach 1 airframe tho (need to nosedive to do it, then stuff starts coming off the plane).
