Manufacturer
Bushmaster Aircraft Corp
Formed in August 1970 to produce a modern version of the 1920s Ford Tri-Motor under the designation Bushmaster 2000. This updated design of the aircraft first built by the Stout Metal Airplane Company was evolved by Aircraft Hydro-Forming Inc. This latter company was acquired by the Whittaker Corporation in February 1969, which wished to dispose of the Tri-Motor program. Improvements, by comparison with the original design, included more powerful lighter-weight engines with constant-speed fully feathering propellers, and new systems.
Bushby

Buscaylet et Cie
France
Built aircraft under subcontract during the First World War. In 1923 secured services of Louis de Monge as a designer, producing in 1924 a single-seat monoplane fighter with 300 hp Hispano-Suiza engine. It was notable for being of all-metal construction, except for fabric covering of wing and tail surfaces.
Burnelli Aircraft Corp
USA
Founded 1920, the Remington-Burnelli Airliner was produced in that year. Vincent Burnelli concentrated on the development of fuselage structures which would contribute some degree of lift, augmenting that of the wing.
Uppercu-Burnelli Aircraft Corp formed 1930 to develop the theories of Vincent Bumelli on aerofoil-shaped fuselage structures; occupied the former Aeromarine Plane & Motor Company plant at New Jersey. First project was Model 101 high-speed twin-engined transport developed from earlier Remington-Burnelli Airliner projects, the 1920 RB-2,1927 CU-16 and 1929 UB-20. Subsequently became the Bumelli Aircraft Corporation.
The Burnelli VB-14B transport of 1936 could accommodate a crew of two and 14 passengers in a fuselage which was virtually an integral part of the wing.
In 1935 the assets of Aeromarine Plane & Motor Co were sold to Burnelli Aircraft Corp.
Burgfalke Flugzeubau
Germany
Building originally examples of the Scheibe and Vogt sailplanes, Burgfalke developed a two-seat lightweight semi-aerobatic training aircraft designated M-150 Schulmeister. It was based on the WN-16, which had been designed by the Wiener-Neustadt company.
Burgess Company
Established at Marblehead, Massachusetts, originally built Wright types under license. By arrangement built three single-float seaplane variants of the British Dunne tailless biplane, two of which were sold to the U.S. Navy which carried out its first experiments in aerial gunnery using these aircraft. Produced also in the period 1916-1918 a number of training and experimental seaplanes of original design.
Burgess Co was acquired by Curtiss in 1916
Burgess-Wiseman
E.H. Wiseman and R.C. Burgess of Cleveland, Ohio, USA, circa 1911.
Bunyard Aircraft Co
In 1931 K. Bunyard designed and built a small biplane flying-boat, following this with a design for an unusual amphibian which failed to materialize in prototype form. At the end of the Second World War he began production of a three-seat lightweight amphibian flying-boat know as the Bunyard BAX-3 Sportsman. A four-seat version was designated BAX-4.
The company was founded in 1931 in Westchester, N.Y. and around 1946 had a slight name change and moved to Flushing, N.Y.
Bulté, René / Avions Bulté & Cie
Until June 1928 Renée Bulté had been head of design with Ateliers de Construction Aéronautique de Zeebruges, usually known as ZACCO and one of the pioneers of all-metal aircraft manufacture. He left them to found his own company, Avions Bulté & Cie. Its first product, the RB.1 tandem seat training aircraft, flew towards the end of the year.
