1911 = 1pOB copy of Curtiss with trailing-edge ailerons and monoplane front elevator.

Baby 1911 = 1pOB. Claude Grahame-White. POP: 3. Contract manufacture of 1911 Burgess.

Mono 192? = Unknown type with Genet motor. [944M].

Bee Gee Baby 1948 = 1p CmwM; 85hp Continental C-85. Midget racer Old Needle-Nose [N1303V]; destroyed in testing 1948.

BT-1 1928 = 4pOB; 150 Hisso I; span: 37'0" length: 18'6". POP: 1 [2850] c/n 1. Also seen as [2851] c/n 1, which was "a temporary ID issued erroneously," according to a NASM abstract, and which was cancelled in 1929 and replaced by the lower number.

  Gray Special [N724DG] (William T Larkins]

Special 2002 = Turboprop version of Legend. 2pClwM rg; 657hp Walter M601D (Czech); span: 28'6" length: 25'9" v: 356/334/120 range: 944.

This address appears in certain records, and is likely connected with the following Gray Goose, but no satisfying trail can be established, so we treat it as a separate entity until otherwise educated.

  Cyclogyro [4308] (magazine clip)

Cyclogyro c.1937 = 1pOM; 7hp Harley-Davidson. POP: 1 ultralight VTOL experiment using minimum power, it was hardly more than a set of wings and a tail mounted on a motorcycle [4308] c/n 1. Originally designed in 1923, articulated slats, connected to the motorcycle, set the heavily-braced wings into a flapping frenzy, but before it got any serious ideas about flying its tail broke off.

  Gray Goose

Windmill Plane c.1936 = Ornithopter type, with four tandem walking beams that opened and closed ten overhead slats, all of this mounted on a ponderous, four-wheeled gondola with an unknown, but seriously large, powerplant. No record of flight was found. This odd bird appears in the video, "Golden Years of Aviation," showing its set of rotating wings on either side of an horizontal axle. It was able to taxi only after being pushed by 10 men, but was never seen flying. Read the intriguing Gray Goose story. SEE ALSO Lewis-American for more knots yet to be untied.

XB-1 1928 = 7pCM; 420hp Lincoln-Liberty 12; span: 50'0" length: 32'0"; ff: 5/25/28(?). [5773]. Crashed at Pico Rivera (CA) on 7/7/28, killing pilot and company vice-pres Howard Blanchard and a passenger. There is a distinct possibility that Blanchard was screenwriter for the aviation film, "The Lone Eagle" (1927), then his writing career ended abruptly there.

AT-19 1979 = 2pClwM; 180hp Lycoming O-360-A1A;span: 24'4" length: 21'0" load: 715# v: 218/198/58 range: 600; ff: 5/24/79 [N23GA]. Side-by-side cockpit, V-tail, tailwheel.

1901 = 1pOB; span: 40'0". Little information on this craft either built by Green, then treasurer of US Aeronautic Society, other than it had three props—two tractors and one pusher. Obviously unsuccessful at flight or we would have heard about it.

Burco Sport 1934 = 2pOM; 65hp Velie. [13540] c/n 101.

Bicraft 1935 = 2pClwM rg; two 50hp Menasco M-50. All-wood geodetic basket-weave construction, evolved from Yates Oregon O; tandem seating. Originally had 40hp Continental A-40. POP: 1 [15546], with a few more reportedly built by other individuals. Greenwood is reported in some references as later (c.1940) appearing with Player (qv), another basket-weaver; however there could very well be a journalistic mixup of his name, and presence, with that of Player's president in 1940, John Greenleaf. To furrow more brows, Fall 1962 AAHS Journal tells of a W I Greenleaf, who "backed Mr Stroop [ed: inventor of an 'Arcuate Control System' in 1932] and was one of the first executives in the country to use an airplane in his business travels." An attendant photo shows Mr Greenleaf standing behind a lanky teenager, who might be little John.

GN-1 Aircamper 1965 = 2pOhwM; 65hp Continental A-65-8; span: 29'0" length: 18'1" v: 115/90/35 range: 400; ff: 11/x/65. Modernized version of Pietenpol Aircamper. Piper J-3 cut-down wings, struts, and landing gear. Engine options up to 85hp.

A-75 1936 = 2pClwM; 75hp Continental C-75; span: 35'11" length: 22'6" v: 116/x/x range: 440. Emigh Rocket repowered and renamed; aka Emigh-Gregg. POP: 1 [NX21963].

Gregor received US patent #1,747,001 in 1930 for a cockpit-controlled wing-tip aileron device to help overcome stalling, but there is no record of this ever showing up on any wing-tips.

Lionheart 199? = 4pCB rg; 450hp P&W R-985; span: 31"0" length: 27'0" load: 1900# v: 230/200/56 range: 1500 ceiling: 20,000'. Negative-staggered wings a la Beechcraft 17. Composite material construction. Flaps all wings. Kits marketed to home-builders for $86,900. POP: 2.

  Grinnell-Robinson Biplane (Bill Owen coll via Ralph Cooper)

Biplane 1916 = 2pOB; no specs found. Robinson, in whose honor the Grinnell airport is named, died on 3/11/16 when attempting to break the current altitude record in his creation. For the full story, see Dr Cooper's impressive Early Aviators site.

SEE ALSO Convair 111.

1936 = 1pOH, human-powered; rotor: 14'0". Dr W Frederick Gerhardt, head of the Aeronautical Engineering Dept. No more than a basic framework with part of a bicycle suspended beneath a two-bladed rotor, this was the first heavier-than-air machine to attain flight, albeit only in inches, with human pedal-power supplied by Olympic fencer Johanna de Tuscon.

  Gyrodyne GCA-2 [N74101]
