Finnish scenery designers made a great representation of Malmi airport for FS9 (

Malmi was opened to traffic already in 1936, but officially it was opened only two years later. The still existing hangar was one of the biggest of its kind in Europe, providing shelter enough to six Ju52s.
The terminal itself is a art of work, proctected by museal laws. Unfortunately the airport itself is not, and the greedy politicians and real estate dealers have already laid their eyes on it. As Finland´s busiest GA airport its existence is at stake at the moment. It is also a home to numerous flying schools and to a Finnish Border Guard unit flying helos (Koala and Bell´s 412).
In sim, this is a very exciting place to fly. There are some modern buildings around the airport, but not too much. If you have for example Flight1´s DC-2, Malmi is perfect for you. Finnair´s predecessor Aero had it and flew it to Stockholm via Artukainen and Åland, to Berlin and to Tallinn. Polish LOT flew there too connecting Helsinki and Warsaw. ABA of Sweden was also a regular visitor. During the war Malmi saw plenty of military operations. In defence of Helsinki a various fighter groups were located there and a Finnish sub-hunting unit with war booty SB-2s. Then the Russians kept it to themselves for a while. After the war it was a beehive until the Seutula, or Helsinki-Vantaa was opened to cope with the Olympic games traffic. American AoA and Pan Am gave finns a possibility to reach States by connecting Helsinki with DC-3s to larger hubs in Stockholm or in Copenhagen.
So, if you are looking for a vintage airport, grab this.
