A Polish border guard plane was disrupted by a Russian plane. It was carrying out a routine patrol over the Black Sea, as part of a mission coordinated by the European Agency.
Three times, the Russian fighter, a Sukhoi Su-35, approached the Polish plane. Aggressive and dangerous maneuvers caused Polish pilots to lose control of the aircraft, a Turbolet L-410. With the turbulence created, the aircraft lost altitude, but it was able to land in Romania, without incident.
