Fong Yue (also seen as Fung Joe Guey and Feng Ru), Oakland CA.
1909 = Little was documented about the intriguing adventures of this young Chinese immigrant. Yue (or the now more accepted spelling of his name, Feng Ru) founded an aircraft factory and constructed two aircraft. On its test flight the first one crashed into his own workshop, starting a fire that burned it to the ground. Assumably the airplane went with it, but Yue was undaunted, and built a second ship that he flew from the Piedmont Hills on 9/21/09, as reported by Associated Press. After 20 minutes a bolt on its propeller shaft broke and it, too, crashed, and its creator was thrown out, but escaped injury. He returned to China in 1911 with his mechanic and two Curtiss planes, and built China's first aircraft. Yue was killed in a crash there in 1912, but his legend is perpetuated by a play, "Dragonwings," last presented, as known, in San Francisco 1992.

J S Zerbe, Fayetteville AR.
Zerbe Air Sedan (1914 Aeronautics)
Air Sedan 1909 = 4pC quadruplane; 100hp Gnôme or 90hp LeRhône rotary. Four short-span, double-cambered, forward-staggered wings, apparently with a ganged variable angle of attack; plywood-clad cabin. Flown by Tom Flannery from a field on the Washington County fairgrounds for a distance of about 1,000' before being damaged on landing. No other flights were recorded.
Zerbe Quintaplane (clip: Dave Hatfield coll)
Zerbe Sextuplane (Library of Congress archives)
Quintaplane 1910 = Another of Zerbe's oddities, with five wings attached to what appears to be a flying motorcycle. Whether or not it ever flew is unknown, but at the 1910 Dominguez Hills Air Meet in Los Angeles it was reported as being "a casualty before becoming airborne." Zerbe then produced a sextuplane with six 15' wings forward-staggered over a framework bearing two tractor props, but again there are no records of its success, if any.
Pete Jordon and I have established his identity as James Slough Zerbe (1849-1921). Pete recently found a newspaper photo from around 1908 that supposedly shows the 5-6 wing "multiplane" (not the Air Sedan) in the air, although the photo is so bad it may have been faked. ( Steve Koons 12/26/07)

Zimmerman Wind tunnel testing (NACA)
1935 = A 1pO low-aspect-ratio "flying pancake" developed in off-times by C H Zimmerman, John McKellar, and Richard Noyes, then with NACA, for design competition with Ercoupe and Stearman- Hammond; two 25hp Cleone; span: 7'0". Although rejected by NACA at too radical, despite its potential as a stall-proof airplane, elements of the design surfaced later in Vought V-173 and Vought-Sikorsky XF5U-1. US patent #2,108,093 issued to Zimmerman in 1938. POP: 1, never flew. Unable to synchronize the motors, rather than risk an accident the project was abandoned. SEE ALSO Hiller VZ-1, McCormick-Romme.

1909 = 1pOB; 25-35hp chain-driving two pusher props; span: 37'0" length: 41'0". Described in Jane's as having Voisin-type bowed wings with ailerons; horizontal tail forward, and a vertical one aft. This intricately-detailed drawing from 1909 Jane's shows why researchers get gray hairs early in life.

Plane-Mobile Concept art by Ted Grohs (Tim Kalina coll)
Plane-Mobile [NX30031] (Tim Kalina coll)
Plane-Mobile 1947 = 2pChwM roadable airplane; 40hp Continental A-40; span: 31'6" length: 15'6" load: 375# v: 90/80/40 range: 285. [NX30031]. Floating, or pivotal, wing, free to change its angle of attack according to the vagaries of the air currents. There were no rudders or elevators in the tail, instead the wings had "ailerators," a combination of ailerons and elevators. Looking somewhat like an Aeronca C-3 gone haywire, it reportedly suffered a severe ground loop during a test flight. Attached graphics are from Daniel Zuck's book, An Airplane In Every Garage (1958 Vantage Press).
