Ukraine closed its airspace in February 2022, when the Russian invasion began. President Volodymyr Zelensky's team has launched a plan to resume passenger flights at kyiv airport during the war.
Only four planes have left the country since then: two Turkish military planes that were in Ukraine when the war broke out; a plane from the Hungarian airline Wizz Air; and the last, last December, a Boeing 777 from the Ukrainian company Skyline Express. Deactivating the transponder is one of those maneuvers that the International Civil Aviation Organization (ICAO) strictly rules out in its manual for civil flights.
