The Finnish Defence Ministry bought 12 Gnats in October 1956 and allocated serials GN-101 to 110 for the fighters, and GN-112 and 113 for the photoreconnaissance versions. The planes were allocated to Hävittäjälentolaivue 11 based at Jyväskylä (EFJY). Despite the Gnat's positive features, it was a new and untried aircraft with deficiencies and design flaws. Unfortunately, it was troublesome in service, demanding repairs, modifications and technical issues that required constant attention. Four of the twelve were lost in service but this example is now a nice gate guardian at this super museum.

This C-47A was built at Oklahoma City and Taken on Charge with the USAAF as 43-48254. In October 1947 the plane started flying with Aero O/Y (the forerunner to Finnair) as OH-LCF 'Kyytipoika'. Its military career resumed in February 1960 when it went to the Finnish AF as DO-4. The plane was earmaked for preservation and by May 1982 became part of the (predecessor museum to the) Suomen Ilmavoimamuseo.

In June, 1942 this plane along with 7 other B-239s engaged 10 Soviet Hurricanes. The pilot, Lt. Pekuri, shot down two Hurricanes but his damaged plane crashed on Lake Big Kolejärvi, near Segezha, Russia and sank. Lt. Pekuri survived and in 1950 became the first Finnish pilot to exceed the speed of sound. After an undertaking by the National Museum of Naval Aviation in Pensacola, Florida the wreck was rediscovered in 1998 and recovered. Since 2009, the aircraft, as the world's only surviving Brewster, has been on loan to the Suomen Ilmavoimamuseo where it is preserved in its battle damaged state.

Built in 1934 by the Vaasa Aviation Enthusiasts' Club based on German design plans published by Hans Jacobs in 1932. It was one of the first gliders in Finland and the only one of its kind in service there. It first flew on February 28, 1935, and remained in service until 1939. The glider was severely damaged by bombing during the Winter War and ultimately destroyed in the 1960s during the demolition of a small hangar on the outskirts of Vaasa Airport. Only the fuselage boom with the rudder survived, now on display at the Museum.

The PIK-12 is, to date, the only two-seat glider designed and built in Finland. The prototype made its first flight in May 1956. Besides the prototype, only three gliders of this type were built between 1957 and 1965. The airframe on display at the Museum was built in 1965 and deregistered in 1980.

The PIK-5 is a Finnish single-seat wooden glider, developed from the Polish WWS.1 Salamandra. The prototype first flew in September 1946. A total of 34 PIK-5s were built, and this type of glider was the most popular glider in Finland during the 1950s. The OH-PAR airframe on display at the Museum was used by the FK Cumulus aeroclub in Helsinki from 1950 to 1977.
