Development
The RWD 5 was constructed by the RWD team of Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki (their designs were named RWD after their initial letters). It was a further development of earlier RWD aircraft series (RWD 1, RWD 2, RWD 3 and RWD 7), especially of its direct predecessor, the RWD 4. It shared the same wing shape and construction, while the fuselage was totally new, constructed of steel frame, unlike its wooden predecessors. The fuselage had a modern shape and a closed canopy with panoramic windows (earlier models had atypical fish-shaped fuselages with no direct forward view from the pilot's seat).
The first prototype (registration SP-AGJ) was flown on 7 August 1931 by its designer Jerzy Drzewiecki. It was built in new workshops of Warsaw University of Technology near Okęcie airport, from 1933 converted to Doświadczalne Warsztaty Lotnicze (DWL) company.
After successes of the prototype in air competitions, a small-scale series production was set up, mostly for the Polish Aero Club. Series aircraft had improved landing gear. Two were built in 1932 (registration SP-AJA and AJB), five in 1933 (including the single-seater RWD 5bis), eleven in 1934 (including one in Aero Club workshops in Lublin) and one more in 1937 (SP-BGX), for a total of 20 aircraft. In 1932, the RWD 5 was shown at the International Air Show in Paris.

Famous quotes containing the word development:
“The American has dwindled into an Odd Fellow—one who may be known by the development of his organ of gregariousness.”
—Henry David Thoreau (1817–1862)
“I’ve always been impressed by the different paths babies take in their physical development on the way to walking. It’s rare to see a behavior that starts out with such wide natural variation, yet becomes so uniform after only a few months.”
—Lawrence Kutner (20th century)
“Such condition of suspended judgment indeed, in its more genial development and under felicitous culture, is but the expectation, the receptivity, of the faithful scholar, determined not to foreclose what is still a question—the “philosophic temper,” in short, for which a survival of query will be still the salt of truth, even in the most absolutely ascertained knowledge.”
—Walter Pater (1839–1894)
