The Aero A.38 was a Czechoslovakian biplane airliner of the 1920s and 1930s. Following the relatively modern A.35, this aircraft was something of a throwback, marrying a fuselage derived from the A.35 to wings copied from the A.23. A few served with CSA, and others with French airline Compagnie Internationale de Navigation Aérienne. These latter aircraft were powered by a French Gnome-Rhône engine instead.
The Embraer EMB 121 Xingu is a twin-turboprop fixed-wing aircraft built by the Brazilian aircraft manufacturer, Embraer. The design is based on the EMB 110 Bandeirante, using its wing and engine design merged with an all-new fuselage. The EMB 121 first flew on 10 October 1976.
The Beechcraft Model 99 is a civilian aircraft produced by Beechcraft. It is also known as the Beech 99 Airliner and the Commuter 99. The 99 is a twin-engine, unpressurized, 15 to 17 passenger seat turboprop aircraft, derived from the earlier Beechcraft King Air and Queen Air. It uses the wings of the Queen Air, the engines and nacelles of the King Air, and sub-systems from both, with a specifically designed nose structure.
The Boeing B-1 is a small biplane flying boat designed by William Boeing shortly after World War I.
The Blériot Bl-115 was a French biplane airliner of the 1920s, best remembered for the part it played in the French exploration of Africa. For its day, it was a large aircraft, mounting one pair of engines on the upper wing and one pair on the lower. First flying on 9 May 1923, the prototype crashed on 23 June, killing its pilot, Jean Casale.
The Blériot 125 was a highly unusual French airliner of the early 1930s. Displayed at the 1930 Salon de l'Aéronautique in Paris, it featured accommodation for twelve passengers in separate twin fuselages. Between them, these pods shared a tailplane and a high wing. The centre section of wing joined the fuselage pods and also carried a nacelle that contained an engine at either end and the crew compartment in the middle. When flown the following year, it displayed very poor flight characteristics and although attempts to improve it continued on into 1933, certification could not be achieved and the sole prototype was scrapped the following year.
The Blériot 155 was a French airliner of the 1920s. It was a four-engined biplane developed from the Blériot 115 and 135, but larger than these aircraft. Two were built for use by Air Union on their Paris-London route. Both were lost in accidents in 1926.
The Blériot 165 was a French airliner of the 1920s. It was a twin-engined biplane, a final development in the family of designs that began with the Blériot 115. Two were built for Air Union to replace the Farman Goliath on their Paris–London route and were christened Leonardo da Vinci and Octave Chanute. The airline found that it preferred the Lioré et Olivier LeO 21s that it had ordered alongside this aircraft, meaning that no further examples were produced.
The Blériot-SPAD S.20 was a French fighter aircraft developed near the end of World War I. Too late to serve in the war, almost 100 of these aircraft equipped the French Air Force in the years immediately following. These agile aircraft were also used successfully for air racing and record-setting.
The Blériot-SPAD S.27 was a small French airliner developed soon after World War I. It was produced as a way for the Blériot company to find new markets for its wartime products in the postwar market, in this instance by adapting the design of the S.20 fighter into a small airliner. Accommodation for two passengers was provided in a small cabin within the fuselage, but in other respects the S.27 strongly resembled its predecessor.
The Bleriot-SPAD S.33 was a small French airliner developed soon after World War I. The aircraft was a biplane of conventional configuration whose design owed much to the Blériot company's contemporary fighter designs such as the S.20. Four passengers could be accommodated in an enclosed cabin within the monocoque fuselage, and a fifth passenger could ride in the open cockpit beside the pilot. A great success, the S.33 dominated its field throughout the 1920s, initially on CMA's Paris-London route, and later on continental routes serviced by Franco-Roumaine.
The Blériot-SPAD S.46 was a small French airliner of the 1920s, developed from the Blériot-SPAD S.33. Like its predecessor, it was a conventional biplane that seated four passengers in an enclosed cabin while the pilot and occasionally a fifth passenger rode in an open cockpit. The S.46 had a redesigned wing of longer span and a far more powerful engine. The type was employed by Franco-Roumaine, which purchased 38 out of the 40 examples produced for use on their continental European routes.
The Blériot-SPAD S.56 was a family of French airliners developed in the 1920s as various refinements of the S.33 design. All S.56 versions shared two new features: the first was a newly designed, all-metal wing, replacing the wooden wing of earlier related designs and the second was a redesigned passenger cabin, replacing the S.33's four single seats in a row with two rows of double seats. A second access door was also added.
The Lioré et Olivier LéO 21 was a 1920s French biplane airliner and later military transport based on the earlier LéO 20 night bomber.
The Kalinin K-4 was an airliner built in the Soviet Union in the late 1920s which was also adapted for use as a photographic survey aircraft and as an air ambulance. A further development of the K-1, it was a conventional high-wing, strut-braced monoplane with separate enclosed cabin and cockpit. Kalinin undertook the design to offer a locally produced alternative to pioneering Ukrainian airline Ukrvozdukhput, which was at that time flying Dornier designs. The structure was of mixed wood and metal construction, but with major assemblies designed in both wood and metal versions, allowing them to be interchanged. The design also featured a variable-incidence horizontal stabiliser, and the engine mounting was intended to facilitate the ready interchange of different powerplants.
The Lioré et Olivier LeO H-47 was a flying boat airliner built in France in 1936. It was designed to operate passenger services over the South Atlantic, but the outbreak of the Second World War caused the type to be used by the French Navy as a maritime patrol aircraft.
The SNCASE SE-1010 was a late 1940s French photo-survey aircraft designed and built by SNCASE for the Institut Géographique National. One prototype was built, but it crashed and the project was cancelled.
The Handasyde H.2 was a six seat airliner built in the UK in the early 1920s. Only one was completed.
The Blériot-Spad S.45 was a large, four engine French airliner which appeared at the 1921 Paris Salon. It could carry fifteen passengers or be adapted as a bomber.
The Blériot Bl.73, Bl.74, Bl.75 and Bl.76 were large First World War French biplanes designed and built by Blériot. The Bl.73 was built to the BN.3 three-seat night bomber specification, the Bl.74 was to be a bomber-transport, the Bl.75 Aerobus was to be an airliner, while the unbuilt Bl.76 was intended for the BN.4 four-seat night bomber specification. Aside from the Bl.76, just one prototype was built of each type, with both Bl.73 and Bl.74 prototypes being lost in accidents while on test flights.
