This is not an UFO flight but this is an airplane without vertical flight if it can fly like our primitive airplane on wings (with attack angle on wings to fly in our air). This 30-meter aircraft can fly at a speed that is not faster than one Mach and it can fly from a glide long speeding-up path for wheels (about 50 meters in length only if wings fly it up always). Usually it flies rarely if NASA does not like it to start because it has no vertical flight only. Two main nuclear reactive motors work in flight usually to back (and rarely to front to slow down all airplane at a fast speed before landing).
