  Dale Weejet 800 [N8209H] (Johan Visschedijk coll)

Weejet 800 1956 = Primary jet trainer. 2pCmwM rg; 920# Continental J69-T-9; span: 28'0" length: 24'0" load: 1970# v: 334/283/65; ff: 3/30/56 (p: Dale). Harold Dale. Side-by-side cockpit, V-tail. POP: 1 [N8209H]; crashed 4/28/56.

Harold worked on the F-100 and later was a chief engineer on the Saturn rocket program. He served as senior consultant to Global Navigation for many years and at my urging among others, developed the "Century Design Series" of aerodynamic design programs that were the standard for amateur airplane designers for a decade. (— Chuck Patten 6/1/05)

George White, with eight other Curtiss and Bell employees. $3,250 projected; POP: 1. Failing to obtain financial backing, the prototype was sold and scrapped in 1948. Reportedly there was also a "sedan" version in the works that was never completed.

Sport Plane 1924 = 1pOB; 45hp Anzani; span: 24'0" length: 19'6". [3934] c/n BTE-SCDC-21. Letter of 8/13/30 (by a T B Jaynes) to CAA about its status: "Plane was dismantled over two years ago and it is not contemplated to ever fly again." Reg cancelled 7/10/30.

de Knight Special SEE de Knight listing below.

Special 1951 = 1pOmwM; 85hp Continental C-85; span: 16'9" length: 20'5" (?>19'0") v: 168 (in racing). Midget racer [N88M]. Orginally built as R&B Special, designed by Edward Walker in Dayton. Crashed on its first flight in 1950, rebuilt and flown successfully in 1951. Later acquired and rebuilt by DARA, flown in races 1958-59 as Miss Dara. Crashed 9/4/66 at Frederick MD from wing failure, killing pilot Oliver Arquilla.

1921 = 2pOmwM; 400hp Liberty. All-metal experimental. A variable-camber wing mechanism was intended to replace the conventional elevators and ailerons. As a precaution, however, conventional controls were also installed. Initially a German 140hp Benz engine was used, which made the airplane terribly underpowered. After changing to a Liberty, a new test flight was made by Eddie Stinson, who was seen to struggle around the field in wide, flat turns—lateral instability is the word. About a year later the machine crashed and was damaged beyond repair.

  Dare Safety Airplane [X3844] (Aviation)

Safety Airplane 1928 = 2pClwM; 120hp Anzani; span: 31'4" length: 23'0" v: 135/115/30-60* range: 600. Variable-camber, hinged-wing design for the Guggenheim Safe Aircraft Competition; *landed at 30mph with deep camber, 60mph without, take-off at 25mph. POP: 1 [X3844].

  There apparently was a fatal 1929 version, the nose of which is seen in this news photo of the inventor and his pilot at Chicago on 7/20/29. Caption: "S W Brown, pilot, left, and Melvin E Dare, inventor are the latest martyrs to aviation. Dare was inventor of a monoplane with flexible wings which he hoped would be able to land at slow speeds. Brown and Dare flew the plane, which plunged 75 feet to earth when the left wing collapsed, causing the deaths of both."

POP: 1 as X-16 [N91793]. Once registered, the model name became D-16, which was purchased by Jack Riley as the foundation for his production of Twin Navions (qv).

  Daugherty (1915 Aviation Age via Joe )

1915 = 1pOB; 50hp Gnôme rotary. No specs or data found, but this could very well be the second of the Max Stupar planes built for Daugherty's exhibition work. In the attendant article, Daugherty was identified as its designer. He also founded Long Beach's civil airport.

Air-Car 1908 = 20pChwM; two 50hp Stanley steam engines; span: 100'0" length: 60'0". Davidson, a British citizen, moved to USA in 1907 where he began construction of his monster flying machine. Half-enclosed in the wings were two 110-blade lifters, each with a diameter of 27'8". Forward and backward flight was to be accomplished by tilting the lifters a few degrees in the appropriate direction. Tailplanes were used differentially for lateral control and in unison for horizontal control, and a rudder was attached to the nose. A preliminary test was made on 5/6/08, when the uncovered central section and the two lifters were completed, but the only power source available was a 10hp Stanley steam engine. By forcing the boiler pressure up to 800psi, Davidson reportedly made the machine lift itself from the ground before the top of the boiler blew off, destroying the whole contraption.

D-1 1929 (ATC 256) = 2pOhwM; 60hp LeBlond 5D; span: 30'2" length: 19'10" load: 495# v: 101/85/38 range: 350. Evolved from V-3. $3,285, $2,995 in 1930; POP: 23.

Based on de Havilland Moth, and was even advertised as "Davis—The American Moth" into mid-1929 before the D-1 designation was adopted. $2,695 early 1929, then $3,285; POP: 22, of which one was refitted with 90hp Cirrus [NC208M].

Racer 1934 = 1pOlwM; 50hp Franklin 4AC; span: 19'0" length: 16'0". [NX/NR84Y]. Appears to be the Hansen Baby Bullet, piloted by Davis and renamed. 1936 and 1938 registers show the motor as a 37hp Continental

Challis B 1956 = 1pClwM; 65hp Continental C-65; span: 22'0" load: 280 v: x/100/50. Relationship, if any, to mid-1930s Challis (qv) is unknown. Built for $1,200. [N3158C].

  Davis Special [N5343N] (clip EAA Experimenter)

Special 1955 = 1pOlwM; 75hp Continental A-75; span: 17'0" length: 15'6" v: 110/x/50. [N5343N]; possibly also [N5339N].

DA-11 c.1996 = 1pClwM; 18hp Briggs & Stratton Vanguard; span: 12'9" load: 200# v: 155/125/x. All-metal low-power version, similar to DA-9, with tricycle gear, V-tail, and a poignant inscription on its fuselage: "Mower power to the people."

Starship Alpha 1986 = 1pC flying wing; ducted fanjet pusher powered by a Lycoming O-320; span: 40'0" length: 12'0" load: 2020# v: 185/172/52 range: 1800 ceiling: 24,000'; ff: 6/10/86. Goal was to further the Northrop Flying Wing concept as a general aviation aircraft constructed of composite material; however, vandalism of the hangar, including destruction of the partially-built larger 3p Gemini prototype, brought about financial straits. POP: 1 [N5531N]. Reportedly new funding was obtained (2001), and the project was resumed.

After reassembly there, they flew to Shanghai by way of central Europe and southern Asia, shipped the plane to San Francisco, and continued the flight across the US to end a seven-month adventure that covered 24,000 miles, of which 16,000 were flown over 27 nations. Total expenses then? About $6,000, including shipping by boat.

Comet Sport 1935 = 1pOB; 110hp Siemens-Halske. [14516] c/n 2.

Delt-Air 250 1961 = 2pClwM rg; 180hp Lycoming O-360A pusher; span: 16'3" length: 23'5" load: 608# v (est): 240/218/70. Tailpost prop. POP: 1 [N6379T]. Crashed on its first flight 11/8/61, killing Dean. However, the attractive, jetlike delta-wing design appealed to F D Pittman of Sapulpa OK, who obtained the wreck to rebuild. Whether he did or not is unknown to AeroFiles.

Parasol c.1971 = 1pOhwM. [N2900].

1911 = 1pOB; 30hp Rutenber pusher; span: 30'0". Voisin-type landing gear. Fabric, on the top side of the wings only, was treated with a "secret preparation invented by de Berry's brother" as an elasticizer and preservative.

Codesigner: Ivan Jerome. Rotary-wing aircraft was financed by US Army as Engineering Division H-1. Four six-blade rotors on an open-girder framework, with the motor mounted horizontally next to the pilot's seat. Although tipping the scales at 3400#, the incredibly busy machine lifted its own weight, plus that of pilot Bane and three men hanging from its structure, during tests at McCook Field OH on 4/17/23. By that time it had logged more than 50 flights, but further development was finally halted when stability problems could not be overcome. This claim for a first contests that of Henry Berliner's earlier free-flight at College Park (6/16/22), which is equally credited with the feat.

Helicopter 1940 = 1pCH. 85hp radial with two coaxial rotors. POP: 1, completed by de Bothezat's colleagues after he passed away in 1939 [NX15699].

Although there is claim of the plane never flew and was used exclusively as a ground trainer, there are reports from eyewitnesses that it was used in demonstrations flown by self-taught pharmacist, Logan D McKee. Whichever, it went into storage 1912 and eventually disappeared.

  Dixon (?) Undated postcard identified as "Dixon's Curtiss Hummingbird, South Dakota State Fair." Unknown for sure if he is this Dixon and if this is the plane described below.

c.1909 = No data, but its "boy inventor," according to 1910 Jane's, "is building it for the NY World New York-Albany $10,000 prize race," curiously reported in present tense.

This was not the plane Dixon was building in 1910. That project was never finished. Dixon joined the Curtiss exhibition team and flew a stock Curtiss pusher. He named it "Hummingbird." He flew this from the summer of 1911 until the fall, when he crashed and died in Spokane WA. (— Jim Newman 1/6/01)

Inspired by the aviation exhibits at the 1904 St Louis World's Fair, Dixon began building his first airship at age 11 and completed it at age 13. Named the "Sky Cycle," the cylinderical balloon utilized a bicycle frame and pedals linked to a three-blade propeller for propulsion, and had a large rudder which carried the American flag. He operated it at the 1907 Intl Balloon Races at St Louis. He later built a more conventional powered airship with a gas bag 60' long by 17' diameter and a bamboo frame slung below to accommodate the pilot and its four-cylinder Curtiss motor. He flew that at expositions, as did Ruth Neely, perhaps the first woman to solo in a dirigible, in 1909, so it is probably the one referred to in Jane's.
    Dixon experimented with a flapping-wing aircraft but I assume he saw the futility of that design and ditched it. I found no record of him ever designing a successful heavier-than-air craft, although he probably could have done so had his life not been cut short. In 1911 Cromwell graduated the Curtiss Flying School and became a member of the Curtiss "13 Team"—probably the most skilled group of exibition flyers in the world at that time. He was the first to cross the Rocky Mountains by air, in the fall of 1911, but the following October died at Spokane WA when he stalled his Curtiss and crashed into a railway embankment.
    I visited his grave, alongside those of his sister and mother at Greenlawn Cemetary in Columbus in 1978, where he was buried in his flying clothes. His headstone reads: "Cromwell Dixon, Young Aviator, Loved By All." While there is a monument to his memory at the Helena MT airport referencing his crossing of the Rockies, and the US Parks Service named a park in his honor, there is no monument to Cromwell Dixon in his home town of Columbus. (— Nick Wantiez 6/31/98)

1936 = Roadable helicopter. 1pOH; 40hp air-cooled engine. Coaxial rotor system with cyclic and collective pitch control. "Foot pedals actuated a hinged vane on the tail, counting on rotor downwash for yaw control." In a photo the helicopter is seen hovering, but no test results were found.

Special 1947 = 1pCmwM; 85hp Continental C-85; span: 17'5" length: 16'0". Midget racer [NX1N] (p: Charles Bing); crashed on a cross-country flight in 1953.

1919 = 1pOB; 18hp Henderson. Etienne Dormoy. An early experiment in ultralights—a basic framework with wings and a pilot's seat behind the motor. POP: 1. The idea was carried over into Dormoy Bathtub. This, flown successfully at Selfridge Field, Detroit, and the following plane were sometimes listed as Packard Motor Co products, but were actually spare-time projects by Dormoy and his co-workers while employed there.

  Dormoy 1920

1920 = 1pOmwM shoulder-wing; 15hp converted V-twin motorcycle engine. Etienne Dormoy. Monocoque fuselage; design was based on Deperdussin, and it eventually led to Buhl Flying Bull Pup. POP: 1. For Dormoy's eary efforts, SEE ALSO Schmidt.

  Dormoy Bathtub (Jerry Turner coll)

Bathtub 1924 = 1pOhwM; 25hp 4-cyl Henderson; span: 24'0" length: 13'5" load: 190# v: 70/60/25. Won Rickenbacker Trophy for its class at the 1924 Nationals. Modified in 1925 with a full-length, covered fuselage. POP: 1, with many subsequently replicated by home-builders even into the 1990s.

The 1925 Bathtub was not the remodeled 1924 Bathtub, it was built from scratch. After the 1924 races Dormoy sold it to a farmer, who taxied it around his cow pasture, but was afraid to fly it. It eventually ended up parked in the field, and his cows chewed the wings away. (-- Jerry Turner 6/9/01)

1909 = 1pOB; Buick auto engine pusher. John C Wright, Ben Goodsell; based on the Wright Flyer, and, reportedly, mail-order plans. Converted in 1911 from a glider that was towed into the sky by two horses, and used for student training, it was modified in 1912 to a tractor configuration. Its claim to fame was as the western hemisphere's first warplane when Ford dropped several bombs, fabricated by a Douglas hardware store, on a railroad trestle near Agua Prieta, Mexico, during the border conflict in early May 1913. Little damage done, but this act foretold the darker side of flying machines.

A-1 1931 = No data, but Morehouse engine [12843] c/n A-1. Possibly a kit lightplane. Reportedly crashed in 1932, then Dow, a foreman at Chevrolet Co, repaired and sold it in 1932. It was active as late as 1937.
