RIA Novosti reported that Vnukovo and Domodedovo airports imposed temporary restrictions on the arrival and departure of aircraft at night.
The Russian Telegram channel Baza reported that Vnukovo airport introduced a so-called "Carpet" plan at night, which delayed at least 11 flights [a "Carpet" plan is an airport operational safety procedure for airport services and personnel when an unidentified object appears in the sky].
As this channel reported, the plan was announced at around 02:30 due to the detection of unknown flying targets in the sky.
