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: (Melvin E) Dare Aircraft Corp, 6003 14 St, Detroit MI. 1929: Mona-Farr Plane Corp, 2010 Washington Blvd, Detroit.
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 turnslateral instability is the word. About a year later the machine crashed and was damaged beyond repair.
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).
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.
Ralph A Daugherty, Saginaw MI.
1931 = Unknown type(s) with Salmson engine, very likely kit-built Pietenpols or similars. [75Y] and , both with c/n 6, are either the same plane re-registered, or a mix-up in the records.
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.

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.

Helicopter 1922 = The first helicopter to actually fly untethered. 1pOH; 170hp LeRhôme rotary, later replaced by 200hp Bentley BR-2; span: 26'6" length: 26'6" load: 1000#; ff: 10/19/22 (p: Thurman H Bane) in a flight of 01m:42s at a height of about six feet. 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].

Cromwell Dixon, Columbus OH.
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.

Etienne Dormoy, Detroit MI and Dayton OH.
1919 = 1pOB; 18hp Henderson. Etienne Dormoy. An early experiment in ultralightsa 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.
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.

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)
Charles M Ford, Al M Williams, and members of the Douglas Flying Club, Douglas AZ.
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.
