Flight data showed that two US military aircraft were operating near the Black Sea and the Russian border on the same day.

According to Russian news on the 8th, flight data showed that a US military patrol aircraft was active over the Black Sea that day, and another US reconnaissance aircraft flew along the Russian border for more than 4 hours.

According to the news, a Boeing P-8A "Poseidon" aircraft took off from Varna, Bulgaria at 19:32 Moscow time, heading towards the Black Sea. As of 20:00, the aircraft was still flying over the waters of the Black Sea. The aircraft is mainly used for maritime patrol, electronic reconnaissance and detection and tracking of surface ships and submarines. Bulgarian National Television reported in late October that a similar aircraft arrived in Varna to perform patrols in the western Black Sea.

It is reported that another Bombardier "Artemis 2" reconnaissance aircraft took off from Mikhail Kogelniceanu Air Base in southeastern Romania at around 9:41 and headed north. After flying around the Kaliningrad Oblast of Russia, it flew north along the border between the Baltic countries and Russia towards Estonia. As of 17:50, the plane flew around the Russian border for more than 4 hours, then circled around Kaliningrad Oblast again and returned. The aircraft, converted from a business jet, is often used to fly and conduct radar reconnaissance around the Kaliningrad region and over the Black Sea along the Crimean Peninsula and southern Russia.

It is reported that in recent years, NATO has been unprecedentedly active near Russia's western border. Russia has repeatedly expressed concern about NATO's troop buildup in Europe. The Russian Foreign Ministry has stated that Russia is still willing to dialogue with NATO on the basis of equality, but the West should give up the policy of militarizing the European continent.
