This tour will lead you along with the Moscow to Vladivostok route of the Trans-Siberian Railway, you will land at 18 different airports in different cities where the main stops of the train are.
The longest leg on this Tour is between Tyumen and Novosibirsk, it is 591 nautical miles long so you should choose an aircraft that has a range that is higher than this but i personally would recommend you to fly it with the Grumman Goose G21A. The whole route is 4019 nm long.
