The Hopfner HS-10/32 was a utility aircraft manufactured in Austria in the early 1930s.It was a conventional, high-wing, strut-braced cabin monoplane derived from Hopfner's series of parasol-wing light aircraft that began with the HS-5/28. Three examples flew in late 1932 under the designation HS-10/32, followed by a single example of the improved HS-10/33 the following year, a generally similar aircraft with revised ailerons. The HS-10/33 was eventually purchased by the Austrian Air Force to use as a liaison machine.
The Manshū MT-1 Hayabusa was an airliner produced by the Japanese Manchuria Airplane Manufacturing Company in Manchukuo in the late 1930s. It was a conventional, low-wing cantilever monoplane with fixed tailwheel undercarriage. The flight deck was fully enclosed and separate from the passenger cabin, which could seat six people. The type equipped Manchukuo National Airways.
The Messerschmitt M 24, otherwise known as the BFW M.24, was an airliner developed in Germany in the late 1920s as a further development in the series of designs produced by Messerschmitt, based on the M 18. Like the M 18 and its follow-on, the M 20, it was a high-wing cantilever monoplane with a fully enclosed cabin and fixed tailwheel undercarriage. It was slightly smaller than the M 20, seating only eight passengers instead of the ten that could be carried by the previous aircraft.
The Morane-Saulnier H was an early aircraft first flown in France in the months immediately preceding the First World War; it was a single-seat derivative of the successful Morane-Saulnier G with a slightly reduced wingspan Like the Type G, it was a successful sporting and racing aircraft: examples serving with the French army were used in the opening phases of the war.
The Morane-Saulnier MS.570 was a civil utility aircraft produced in small numbers in France in the late 1940s.
The Nieuport-Delage NiD 30 was a French airliner which entered service in 1920. It was a reverse-stagger biplane design with an enclosed cabin that seated four passengers and an open cockpit for the pilot. Provision was also made for a wireless transmitter, receiver, and operator. Seven examples were operated by Compagnie générale transaérienne on its Paris–London route on twice-daily return services.
The Nieuport-Delage NiD 38 was a touring aircraft built in small numbers in France in the early 1920s. It was a single-bay biplane of conventional design with an enclosed cabin for two passengers and an open cockpit for the pilot.
The Bánhidi Gerle was a two-seat, single-engine sport biplane built in Hungary in the early 1930s, designed by Antal Bánhidi.
The MSrE M-19, also known as the Rubik R-02 after its designer Ernő Rubik, was a sport aircraft built in Hungary in 1937. Sándor Geönczy initially worked with Rubik on the project, but died before it was completed. The M-19 was a conventional, low-wing cantilever monoplane with a wing of elliptical planform and fixed, tailskid undercarriage. The pilot and passenger sat in tandem under a streamlined canopy that fully enclosed the cockpit, and the main wheels were covered with spats. When the design was finalised, Rubik's calculations were verified by the Aviation Institute in Warsaw and a single prototype contrstucted.
The MSrE M-21 Harag was an aerobatics aircraft built in Hungary in 1936, sometimes known as the Szegedy M-21 after one of its designers, József Szegedy. It was a conventional biplane design with single-bay staggered wings of equal span braced by N-struts. The pilot sat in an open cockpit, and the tailwheel undercarriage featured divided main units. Only a single example was built.
The SECAN SUC-10 Courlis was a French high-wing touring monoplane designed and built by Société d'Etudes et de Construction Aéronavales (SECAN), a branch of the automobile company Société des Usines Chaussons. The aircraft had problems with the engine installation and only 144 were built, some without engines and were scrapped.
The Potez IX was an early airliner produced in France in the 1920s, a further development of the SEA IV that Henry Potez had co-designed during the First World War.
The Ryan M-1 was a mail plane produced in the United States in the 1920s, the first original design built by Ryan. It was a conventional gear parasol-wing monoplane with two open cockpits in tandem and fixed, tailskid undercarriage.
The Ryan C-1 Foursome, also known as the "Baby Brougham" was a single-engine, four-seat light aircraft built by Ryan Aeronautical in the United States in 1930 as an executive transport. It was a high-wing, braced monoplane based on Ryan's highly successful Brougham design, but substantially smaller. The interior was luxuriously furnished, with deeply upholstered seats, and an oversize cabin door was fitted to ease boarding and disembarking for the three passengers.
The Ryan Brougham was a small single-engine airliner produced in the United States in the late 1920s and early 1930s. Its design was reminiscent of the M-1 mailplane first produced by Ryan in 1926, and like it, was a high-wing, strut-braced monoplane of conventional design.
The Spartan C5 was a passenger and utility aircraft produced in small numbers in the United States in the early 1930s. It was a further, ultimately unsuccessful, attempt to market the Spartan C4, from which it was developed. Like its predecessor, the C5 was a high-wing, strut-braced monoplane with a fully enclosed cabin. Seating was increased to five places in place of the four seats of the C4. The C5 also incorporated a number of aerodynamic refinements, including a closely cowled engine and spatted mainwheels. The fuselage was constructed of welded steel tube and the wings from wood, and the whole aircraft covered in fabric. The empennage was also mostly constructed from wood, with metal ribs used in the fin and the whole assembly also covered in fabric.
