The Canadian Vickers Vanessa was a Canadian biplane transport floatplane of the 1920s evaluated by the Royal Canadian Air Force (RCAF) and used briefly for delivering air-mail.
The Vanessa was developed as a private venture commercial seaplane.
It was a single-engine, twin-float cabin biplane of mixed construction. The enclosed cabin fuselage was constructed of steel tubing as were various support structures along with the tail surfaces. The wings were of wood construction and the entire aircraft was fabric covered. Its interplane struts were unusual in forming a pair of "X"s on each side, when viewed from the front which eliminated the need for wire bracing and improved access to the cabin. Ailerons were fitted to each of the equal span wings which were linked with connecting rods. As first built, these ran the full span of the wings, but were reduced to about half the span shortly afterwards.
One prototype, registered G-CYZJ, was built, after which the Royal Canadian Air Force indicated an interest in the type as a communications aircraft. Testing indicated that the aircraft was under-powered and the 200 hp (150 kW) Armstrong Siddeley Lynx was replaced with a 220 hp (160 kW) Wright Whirlwind.
In September 1927, the Vanessa was used for several airmail flights.[ citation needed ] On 9 September 1927 at Rimouski, Quebec on the Saint Laurence River about 280 km (170 mi) east of Quebec City, its RCAF pilot received 502 lb (228 kg) of mail from the west-bound RMS Empress of France. While taxiing for takeoff, a wake from a passing vessel hit it, breaking a strut, which then allowed the aircraft's starboard float to be hit by the propeller, which sliced the float in half. The aircraft capsized, broke up, and sank but the pilot escaped and the mail was recovered, which continued on by rail.
The wreck was salvaged but was found to be uneconomical to repair and development was abandoned.
Despite a very brief career, the Vanessa has the distinction of being one of the first enclosed cabin aircraft designed in Canada.

General characteristics
Performance
The Avro Type 621 Tutor is a two-seat British radial-engined biplane from the interwar period. It was a simple but rugged basic trainer that was used by the Royal Air Force as well as many other air arms worldwide.
The Canadian Vickers Vedette was the first aircraft designed and built in Canada to meet a specification for Canadian conditions. It was a single-engine biplane flying boat purchased to meet a Royal Canadian Air Force (RCAF) demand for a smaller aircraft than the Vickers Viking with a much greater rate of climb, to be suitable for forestry survey and fire protection work. The type went on to have a long and distinguished career in civil operations in Canada. Most of the topographical maps in use in Canada today are based on photos taken from these aircraft.
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.
The Canadian Vickers Vancouver was a Canadian transport/patrol flying boat of the 1930s built by Canadian Vickers.
The Canadian Vickers Varuna was a Canadian flying boat of the 1920s built by Canadian Vickers as a twin-engined, unequal-span biplane, with a wooden hull and steel tube structure.
The Avro Type 584 Avocet was a British single-engined naval fighter prototype, designed and built by Avro. While the Avocet was not built in numbers, one of the prototypes was used as a seaplane trainer for the Royal Air Force's (RAF) High Speed Flight.
The Avro 641 Commodore was a British single-engine five-seat cabin biplane built by Avro in the mid-1930s for private use. A total of only six were built, including the prototype.
The Blackburn F.2 Lincock was a British single-seat lightweight fighter produced by Blackburn Aircraft Limited.
The de Havilland DH.75 Hawk Moth was a 1920s British four-seat cabin monoplane built by de Havilland at Stag Lane Aerodrome, Edgware.
The Fairchild FC-1 and its derivatives were a family of light, single-engine, high-wing utility monoplanes produced in the United States in the 1920s and 1930s. The aircraft was originally designed to provide a camera platform for Sherman Fairchild's aerial photography and survey business, Fairchild Aerial Surveys.
The Kawasaki KDC-2 was a 1920s Japanese light civil transport which Kawasaki developed from its Kawasaki Army Type 88 Reconnaissance Aircraft. Two were built and flown in 1928 and flew both regular and irregular services; the last retired in 1935.
The Fokker S.IV was a military trainer aircraft produced in the Netherlands in the mid-1920s. It was a conventional, single-bay biplane with staggered wings of unequal span braced with N-struts, essentially a radial-engined development of the S.III. The pilot and instructor sat in tandem, open cockpits and the undercarriage was of fixed, tailskid type with a cross-axle between the main units. The Royal Netherlands Army Aviation Group purchased 30 examples and used them right up to the German invasion of the Netherlands in 1940. On 14 May that year, a few surviving S.IVs escaped to France alongside some S.IX trainers, but never flew again.
The Canadian Vickers Vista was a Canadian-designed single-seat flying boat.
The Vickers Vellore was a large biplane designed as a freight and mail carrier, in single-engined and twin-engined versions, which saw limited use as freighters and long-range experimental aircraft. A final variant with a broader fuselage, the Vellox, was completed as an airliner.
The Fairey G.4/31 was a British single-engined, two-seat biplane contender for an Air Ministry specification for a multi-role or general purpose aircraft. Unsuccessful, only one was built.
The Canadian Vickers Vigil was a single-seat patrol aircraft designed to meet a Royal Canadian Air Force requirement for a forest fire patrol aircraft.
The CAMS 31 was a 1920s French single-seat fighter biplane flying-boat designed and built by Chantiers Aéro-Maritimes de la Seine (CAMS).
The Stampe et Vertongen RSV.22 was a training biplane produced in Belgium in the 1920s.
The Caspar CJ 14 was a German fighter aircraft prototype built in the 1920s.
The IMAM Ro.26, sometimes called the Romeo Ro.26, was a single-engine biplane trainer aircraft produced by the Italian aeronautical company IMAM in the early 1930s. Only one example was built.
