The Junkers G.38 was a large German four-engined transport aircraft which first flew in 1929. Two examples were constructed in Germany. Both aircraft flew as a commercial transport within Europe in the years leading up to World War II.
The Focke-Wulf A 38 Möwe was an airliner, produced in Germany in the early 1930s. It was a final development of the family of designs that commenced with the A 17 in 1927. The A 38 used the same high-mounted, cantilever wing as the A 29, but mated this to an all-new fuselage design with enclosed seating for ten passengers and three crew. Unlike earlier members of the family, the flight deck was not joined to the cabin, separated now by a lavatory and baggage compartment. The main undercarriage was strengthened and the mainwheels fitted with brakes, while the tailskid was replaced with a tailwheel. All four A 38s were originally fitted with Siemens- or Gnome et Rhône-built Bristol Jupiter engines, but in April 1933, all aircraft were refitted with Siemens Sh 20 powerplants. By mid-1934, they had been relegated to training duties.
The Klemm Kl 36 was a 1930s German four-seat cabin touring and competition monoplane designed and built by Klemm.
The Lublin R-XI was the Polish passenger plane for 4 passengers, designed in 1930 in the Plage i Laśkiewicz factory in Lublin, that remained a prototype.
The Bayerische Flugzeugwerke M 18, was an airliner, produced in Germany in the late 1920s.
The Ago Ao 192 Kurier was a small German twin-engined aircraft designed and built by AGO Flugzeugwerke in the 1930s. A small production run of six aircraft followed three prototypes, these being used as transports.
The Avia 51 was a 1930s Czechoslovakian six-passenger commercial transport, designed by Robert Nebesář and built by Avia. The type was uneconomical in use and only three were built.
The Dornier Do K was a German commercial passenger and freight monoplane, designed by Claude Dornier and built by Dornier Flugzeugwerke. Only three prototypes of different designs were built and the type was not a commercial success.
The Junkers J 29 was a two-seat, single-engined experimental training monoplane, built in Germany in 1925. Its significance is that it was the first aircraft to fly and test the Junkers Doppelflügel control surfaces used very successfully on the later Junkers Ju 52.
The Johansen CAJO 59 was a Danish twin-engined amphibious flying boat. Built in the late 1960s, it achieved certification but did not go into production.
The Stearman LT-1 was a late 1920s American biplane, carrying four passengers plus mail.
The Dewoitine D.30 was a ten-seat cantilever monoplane built in France in 1930. The D.30 was a single-engine aircraft but the second was completed as a trimotor and redesignated D.31.
The LFG V 60 was a small, single engine, tandem seat floatplane training aircraft, designed and built in Germany in the mid-1920s. About five were constructed.
The Potez-CAMS 161 was a large, French six-engined flying boat airliner, designed to operate on the North Atlantic routes that were opening up in the late 1930s. Its development was almost halted by World War II. Just one was built and partially tested before its destruction by Allied forces near the war's end.
The Historical Ryan STA was an American homebuilt aircraft that was designed and produced by the Historical Aircraft Corporation of Nucla, Colorado. The aircraft was an 85% scale replica of the original Ryan STA and when it was available was supplied as a kit for amateur construction.
The Let-Mont Tulak is a Czech microlight aircraft that was designed and produced by Let-Mont sro of Vikýřovice. When it was available the aircraft was supplied as a complete ready-to-fly-aircraft or a kit for amateur construction.
The Curtiss-Reid Courier was designed in Canada in 1931 as a specialist, non-passenger carrying, mailplane capable of maintaining services in Canada's hard winters. The 1930s depression led to the end of government subsidised airmail contracts and only one prototype flew. It was lost in 1933 during preparations for a private, long distance flight.
The Nieuport-Delage NiD 740 was a French trimotor monoplane designed to carry night mail. Two were built in 1930.
The Skraba S.T.3 was a two-seat Polish biplane built in 1928. It was the first all-metal aircraft designed in Poland; only one was completed.
The WT-1 was a 1931 high performance sports aircraft designed in Poland. It only made two flights.
