A new major feature has been added today to all game worlds to make the operation of early era Soviet aircraft more desirable and to better model the effects of state-controlled economy: Government subsidies and incentives. This new feature allows the governments to issue financial benefits for airlines using aircraft produced in their country. In other words if you are based in the Soviet Union and also fly aircraft made in the Soviet Union, the government will pay a large part of your fuel bill and give big discounts for new aircraft purchases (up to 20-30%). If you are based in other friendly country, such as Cuba, you will get similar benefits for flying Soviet aircraft (up to 10-20%). All these communist subsidies end when the Soviet Union collapses (end of 1991). Check the details from the software Changelog.
