The Bristol Aeroplane Company, originally the British and Colonial Aeroplane Company, was both one of the first and one of the most important British aviation companies, designing and manufacturing both airframes and aircraft engines. Notable aircraft produced by the company include the 'Boxkite', the Bristol Fighter, the Bulldog, the Blenheim, the Beaufighter, and the Britannia, and much of the preliminary work which led to Concorde was carried out by the company. In 1956 its major operations were split into Bristol Aircraft and Bristol Aero Engines. In 1959, Bristol Aircraft merged with several major British aircraft companies to form the British Aircraft Corporation (BAC) and Bristol Aero Engines merged with Armstrong Siddeley to form Bristol Siddeley.

The RyanNavion is a single-engine, unpressurized, retractable gear, four-seat aircraft originally designed and built by North American Aviation in the 1940s. It was later built by Ryan Aeronautical Company and the Tubular Steel Corporation (TUSCO). The Navion was envisioned as an aircraft that would perfectly match the expected postwar boom in civilian aviation, since it was designed along the general lines of, and by the same company which produced the North American P-51 Mustang.
The Gregor FDB-1 was a Canadian biplane fighter, designed in 1938 by Michael Gregor and manufactured by Canadian Car and Foundry. Despite having some advanced design features such as flush rivetted all-metal construction and a retractable undercarriage, the final generation of biplane fighters was being supplanted by monoplanes and the Gregor FDB-1 was obsolete before it flew. Despite the Royal Canadian Air Force's desperation for modern fighters, the sole example remained unsold and was eventually lost in a fire in 1945. The Gregor FDB-1's model designation stood for Fighter Dive Bomber indicating its intended roles.

In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of struts, which act in compression or tension as the need arises, and/or wires, which act only in tension.
