Temporary restrictions on aircraft arrivals and departures were imposed at 27 Russian airports, Deutsche Welle reported on 16 October, citing its own calculations based on reports from Russia’s Federal Air Transport Agency.

Ukrainian President Volodymyr Zelenskyy warned airlines on 1 September that “Russian airspace is becoming completely unsafe.” Overnight, most of the airspace over European Russia was closed.

By morning, more than 200 flights had been canceled or delayed at Moscow airports, Deutsche Welle reported, citing figures compiled by a Russian Telegram channel.

The list included airports in the capital. All four Moscow airports temporarily suspended arrivals and departures, the Russian outlet Astra reported on 16 October. Russian authorities said they had shot down dozens of drones, while flights were delayed and diverted to alternate airfields, according to the report.

Massive drone attack on Russia: 644 UAVs in one night, 94 shot down near Moscow

The temporary airport shutdowns were likely a consequence of a massive drone attack on Russia. From 8:00 p.m. on 15 October to 8:00 a.m. on 16 October, Russian air defenses allegedly intercepted and destroyed 644 Ukrainian unmanned aerial vehicles across 26 Russian regions, occupied Crimea, and the Black Sea, according to Russia’s Defense Ministry.

According to the list of regions published by the Russian Defense Ministry, the drone attacks covered a vast area of Russia, from regions bordering Ukraine to the Moscow region, the Volga region, the country’s northwest and southern regions, as well as occupied Crimea and the Black Sea.

Russian air defenses shot down a total of 94 drones approaching Moscow over the evening of 15 October and overnight, according to calculations by the Russian outlet RBC Radio, citing statements by Moscow Mayor Sergey Sobyanin.

In the Kaluga region, air defenses destroyed 27 drones over the evening and night, the regional governor reported. At 9:27 a.m., he updated the figures, saying another 48 UAVs had been shot down overnight, bringing the total to 75. According to preliminary information, there were no casualties or infrastructure damage.

In the Tula region, air defenses allegedly destroyed a total of 32 Ukrainian drones. There were no casualties, according to regional Governor Dmitry Milyaev in his Telegram channel.

In the Vladimir region in western Russia, authorities repelled drone attacks overnight. In the city of Vladimir, a drone attempted to attack a heating infrastructure facility, but the attack was stopped, Vladimir Region Governor Alexander Avdeyev reported. Minor damage was reported, but there was no information about casualties.

Ukraine has not yet commented on its involvement in the attacks.

The practical consequences of canceled Russian flights

Passengers on flight SU6312 from Kaliningrad to Moscow were unable to land in Moscow because of airspace closure, so the aircraft was diverted to Nizhny Novgorod, Terravia reported. After landing, passengers remained on board for about two hours before being allowed to disembark at 3:30 a.m. Instead of continuing their journey to Moscow by air, they were supposed to be transported by bus, with the trip expected to take about seven hours, the outlet reported.

Passengers were not provided with food or drinks, and one woman could not find a seat on the bus, so she purchased a ticket for an early-morning train herself.

Since the beginning of the year, all four Moscow airports have been completely shut down simultaneously at least 19 times, the Russian outlet Agentstvo reported. During the first 14 days of October, the restrictions lasted 101 hours and 38 minutes, compared with 46 hours and 33 minutes in September, according to the report.
