Koolhoven F.K.52
Koolhoven F.K.52 was a Dutch-designed, two-seat reconnaissance-fighter biplane, which was developed in the 1930s by Koolhoven. The aircraft was equipped with an enclosed cockpit and single-strut landing gear. Only six aircraft were produced. The aircraft saw some service in the Finnish Air Force. Design and development The FK.52 was proposed as a replacement for the Fokker C.Vs of the ''Luchtvaartafdeling'' (LVA), the Dutch Army Air Force. The prototype aircraft made its maiden flight on February 9, 1937. The aircraft was however lost in an accident on August 11 of the same year, while displaying in front of Boy Scouts during the 5th World Scout Jamboree. Although the Koolhoven was an obsolete design by 1938, they began building a few FK.52s. The Dutch Air Force ordered 36 aircraft in 1939, but only five had been manufactured, when the Germans invaded the Netherlands. Operational history During the Winter War, two Koolhovens were purchased by the Swedish count Carl Gustav von R ...

Koolhoven
N.V. Koolhoven was an aircraft manufacturer based in Rotterdam, Netherlands. From its conception in 1926 to its destruction in the Blitzkrieg in May 1940, the company remained the second major Dutch aircraft manufacturer (after Fokker). Although many of its aircraft were as unsuccessful economically as they were brilliant from a design standpoint, the company managed to score several 'hits', amongst them the FK-58 single-seat monoplane fighter, the FK-50 twin-engine passenger transport, and the FK-41, built in England under licence by Desoutter. History In 1920, aircraft designer Frederick 'Frits' Koolhoven returned from England to his native Netherlands. The postwar years had not been good to him; the British Aerial Transport Company for which he was chief designer went bankrupt and all other manufacturers were struggling for survival too hard to think of hiring. The Netherlands, Koolhoven hoped, would be better. But there he found that while the Netherlands' new airline K ...

Continuation War
The Continuation War, also known as the Second Soviet-Finnish War, was a conflict fought by Finland and Nazi Germany against the Soviet Union from 1941 to 1944, as part of World War II.; sv, fortsättningskriget; german: Fortsetzungskrieg. According to Finnish historian Olli Vehviläinen, the term 'Continuation War' was created at the start of the conflict by the Finnish government, to justify the invasion to the population as a continuation of the defensive Winter War and separate from the German war effort. He titled the chapter addressing the issue in his book as "Finland's War of Retaliation". Vehviläinen asserted that the reality of that claim changed when the Finnish forces crossed the 1939 frontier and started annexation operations. The US Library of Congress catalogue also lists the variants War of Retribution and War of Continuation (see authority control)., group="Note" In Soviet historiography, the war was called the Finnish Front of the Great Patriotic War..

Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also o ...

1930s Dutch Military Reconnaissance Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Bristol Mercury VIII
The Bristol Mercury is a British nine-cylinder, air-cooled, single-row, piston radial engine. Designed by Roy Fedden of the Bristol Aeroplane Company it was used to power both civil and military aircraft of the 1930s and 1940s. Developed from the earlier Jupiter engine, later variants could produce 800 horsepower (600 kW) from its capacity of 1,500 cubic inches (25 L) by use of a geared supercharger. Almost 21,000 engines were produced, with a number also being built under license elsewhere in Europe. Several examples remain airworthy, with other preserved examples on public display in aviation museums. Design and development The Mercury was developed by the Bristol Aeroplane Company in 1925 as their Bristol Jupiter was reaching the end of its lifespan. Although the Mercury initially failed to attract much interest, the Air Ministry eventually funded three prototypes and it became another winner for the designer Roy Fedden. With the widespread introduction of superchar ...

Forest Brothers
The Guerrilla war in the Baltic states was an armed struggle which was waged by the Latvian, Lithuanian, and Estonian partisans, called the Forest Brothers (also: the "Brothers of the Wood" and the "Forest Friars"; et, metsavennad, lv, mežabrāļi, lt, žaliukai), against the Soviet Union during the Soviet invasion and occupation of the three Baltic states both during and after World War II. Similar anti-Soviet Central and Eastern European resistance groups fought against Soviet and communist rule in Bulgaria, Poland, Romania, and western Ukraine. The Red Army occupied the independent Baltic states in 1940–1941 and, after a period of German occupation, it re-occupied them in 1944–1945. As Stalinist repression intensified over the following years, some 50,000 residents of these countries used the heavily forested countryside as a natural refuge and base for armed anti-Soviet insurgency. According to some estimates, 10,000 partisans in Estonia, 10,000 partisans in ...
