Vladivostok Air
Passenger flights from Vladivostok to Moscow began using Ilyushin Il-12 airliners in 1948. Five years later, in 1953, the Antonov An-2 commenced service, becoming a significant educational tool for Vladivostok Air, allowing pilots to amass experience in a number of different flight-related activities, while carrying several thousand passengers. Taking over the workload of the Po-2, the An-2 "Annushka" became a nearly irreplaceable aircraft for Vladivostok Air's agricultural charters. Vladivostok Air also began basic use of the Lisunov Li-2 aircraft, which would continue to operate regular passenger flights from Ozernye Klyuchi Airport to Khabarovsk for the next 15 years.
