MOSCOW, November 13. /TASS/. A US-registered NATO reconnaissance aircraft spent five hours circling around Russia’s westernmost Kaliningrad Region on Friday, a source in air traffic control services told TASS.

"A Bombardier Artemis II reconnaissance aircraft was detected in the vicinity of the Kaliningrad Region for the third time this week. It spent five hours flying there," the source said.

According to the source, the aircraft arrived from its permanent base in Constanta, Romania, and was flying in the airspace of Poland and Lithuania and the Baltic Sea’s neutral waters at an altitude of about 10 km, away from corridors designated for civilian aircraft.

The source also recalled that the Bombardier Artemis II had been sighted near the Kaliningrad Region more than 70 times since the beginning of this year. It was last seen in the area on Thursday and on Monday, when it was in the air for more than five hours.
