Russian MiG-31BM upgraded fighter jets practiced combat maneuvers in the lower stratosphere.
One of the aircraft imitated an intruder trying to enter into the Russian airspace to collect data, flying nearly 15,000 meters above the mean sea level.
Pilots flying the aircraft at supersonic speeds at an altitude of about 18,000 metres above the mean sea level found and captured the “enemy” aircraft, the Russian MoD said in a statement Friday.
