According to the US Air Force: At approximately 11:19 a.m. on Aug. 28, 2020, two Russian Su-27 Flanker pilots intercepted a U.S. Air Force B-52 bomber that was conducting routine operations in the black sea over international waters. The Russian pilots flew in an unsafe and unprofessional manner while crossing within 100 feet of the nose of the B-52 multiple times at co-altitude and while in afterburner causing turbulence and restricting the B-52’s ability to maneuver. The B-52 Stratofortress aircraft was conducting routine operations in international airspace exercising our freedom of navigation and overflight. The U.S. Air Force routinely operates aircraft in the region in accordance with recognized international safety standards as prescribed in International Civil Aviation Organization (ICAO) rules of flight.
