1942 Aerosphere makes no mention of Pasped and, as for Skylark, "Skylark Aircraft Corp of Venice, California, has become inactive." (This is understandable with the advent of WW2.) Also, "The two-place Skylark airplane formerly built by this company was described ... in Aerosphere 1941." There is no mention of either company or the airplane in Jane's from 1941-45 or Aircraft Year Books of that same era. When Perkins took over is unknown, as Pasped co-founder Pederson was shown in 1941, but not his partner, Fred Pastorius.

    (Historian Lennart Johnsson suggests a special page for only "Skylarks" to feature all those made by Bücker, Columbus, Driggs, Galvin, Larkin, Pasped, Phillips, Watkins, et al.)

1910 = 2pOB; Emerson marine engine pusher. Rex Smith, Frederick Fox; ff: 11/6/10 (p: R Smith). Used in Signal Corps experiments with wireless radio-telegraphy in April 1911 (p: Antony Jannus). Operations continued until 1916 in building several other Curtiss-type biplanes.


1910: Arthur L Smith, Ft Wayne IN. 19??: San Francisco CA.

1910 = 1pOB; 60hp Eldridge chain-driving two pusher props; span: 40'0". This was the end result of two prototypes that crashed, mainly because Smith was teaching himself to fly as he went along. A replica of this ship, built by Billy Parker and Bob McComb, is now hung on display at Ft Wayne Intl Airport terminal. Smith also previously built a "gasless air-ship," according to 1909 Jane's—no specifics given.

From books and magazine articles Art learned about aircraft construction, designs, and patents. He believed he could build a plane that would fly better than the Wright airplane, and as he worked on his design, he was careful to avoid infringing on their patents. It took him and a friend six months to build the plane, which they moved through the streets of Fort Wayne at night to a field in what is now Memorial Park. The next morning, in its first test the plane reached almost 50 mph before leaving the ground. Suddenly it rose alarmingly, dipped, rose again, and crashed. Art was thrown onto the frozen ground and seriously injured; the plane was ruined except for the engine. (— excerpt; article by Rachel Sherwood Roberts, Indiana Historical Society)

c.1915 = Three aircraft are said to have been constructed for Smith's exhibition performances at the 1915 Panama-Pacific Exposition by Al Mensaco. The use of "Smith-Curtiss Pusher" in a contemporary journal leads to an assumption of their being Curtiss machines assembled by Smith, or copies using Curtiss motors. Smith was pictured in several different types of aircraft during this period, most of them looking much like the tried-and-true Curtiss designs—or at least faithful replicas.

Monoplane 1911 = No specs or data found.


Floyd Smith, San Diego CA.

1912 = 2pOB; 60hp Hall-Scott. Claimed to be the first tractor biplane built in the US. With his wife, Smith flew from Santa Ana to Griffith Aviation Park (Glendale) on 7/19/12, an ambitious cross-country flight at the time—the 45-mile journey took 01h:07m!

Smith, West Virginia

Kyle Smith Aircraft Co, Wheeling WV. 1919: West Virginia Aircraft Co.

  Kyle Smith ad (Aviation 5/1/17 via Dennis Parks, MOF 4/6/07)

1917 = 2pOB; no specs or data. $3000, $3100 for "water model"; POP: probably just the prototype.

c.1918 = 1pOB; pusher motor. Twin-tail, headless Wright-type design, with trailing-edge ailerons on upper wing.

C-3 (West Virginia) 1919 = 3pOT; 150hp Wright-Hispano A (pusher?). POP: reportedly at least 3.


H J Smith, Minneapolis MN.

June-Bug Aerial Flivver 1922 = 1pOmwM; 30hp 2-cyl engine. Described as "a bathtub with a pole stiking out behind it" and wearing a child's tricycle wheel on its tail. Did it ever fly? Planned maiden flight in mid-May at the State Fairgrounds (some say Curtiss Northwest Airport) was delayed by a balky engine and the tailwheel breaking off, and no further account was found.


Edward F Smith, 354 W Anderson St, Hackensack NJ.

ES-5 c.1929 = 2pOhwM; Anzani. Rounded sides, parasol wing. Sold to J E Brown of Camden, who apprently repowered with a Hisso.

S-1 1928 = 2pOhwM; Anzani. Slab sides, parasol wing. [987H] c/n 22, used by Ivan Gates in exhibition work.


J W Smith, Cicero IL.

c.1929 = 1pOhwM. Monocoque fuselage made from red fiber paper rolled into shape and riveted. Wing were steel-tubing framed—the first-ever wing to have metal ribs. The fuselage hung below the wing with a pivoting arrangement somewhat like that which George Spratt would champion much later. According to William B Stout, "Its one bad habit was changing shape from day to day as the humidity increased or decreased."

Elmer L Smith, Eugene OR.

1933 = 1pOB; 45hp Salmson; span: 22'5" length: 15'6" v: 95. Began life in 1929 as White 25 with a 25hp Henderson De Luxe engine, built by L J White, Pasadena CA. Not even the "De Luxe" addition helped very much. The aircraft would hardly fly. Smith bought it, increased the span of the upper wing, mounted the more powerful engine and flew it successfully. [10684]. After WW2 it was acquired by Hobart Sorrell in Rochester WA, who refitted a 65hp Continental, reregistered it as [N4940V], and renamed it Peer Gynt. It was active at least into the 1970s.

Advertised as "automatically stable," it might have been a copy, rather than a rebuild as thought, of the Morane-Borel since that import retained its original look throughout its life. That Borel had a very involved and hand-me-down career before ending up as a display relic, acquired from Earl Daugherty, at the Tallmantz Movieland of the Air (aka Intl Museum of Flight at Orange Co CA Airport) in the 1960s. Modified to some unknown extent—perhaps just renamed—as the Mathis-Mestach Exhibition Monoplane c.1911.

1914 = On 4/12/11, at age 17 in a rebuilt Curtiss-type modified as flying boat—he had convinced his father to invest in the wreckage—Spencer not only took his creation on its first flight but on his own solo flight, as well. Unskilled in turning the plane, he flew for five miles, landed on a river, and pushed it around for the return flight. Of pertinence is that Spencer was still actively flying in 1987 at age 90.

S-10 Monoplane 1922 = 1pOlwM; 25hp Lawrance La-3; wings from a Curtiss Oriole. Described by its inventor in Jan 1984, then 87, as "... a little puddle-jumper I made just for fun at Brainerd Field, Hartford CT, in 1922... The fuselage was laid out on the floor with spruce longerons and corner gussets and was fabric covered. The cockpit opening was formed by the wood rim of a bicycle wheel... (The) engine quit and parts began falling (but made a) normal landing. There was a teenager in the assembled crowd and I gave the plane to him. I don't know if he re-engined it or what became of the plane." Appeared in 1926 as Spenser [sic] with 35hp Lawrance—possibly the re-rated La-3; span: 32'0" length: 20'0" load: 220# v: 55/50/28.

Designed at McCook Field by Alfred Verville; aka Engineering Division M-1. Ailerons on all wings. POP: 22 as military M-1 and 20 as M-1A [AS64223/64227, AS68472/68477, AS68528/68533], plus 1 civil sport version that failed to spark any public interest, and the idea was never pursued. Of the first dozen, 8 were modified as remote-control flying bombs with the designation MAT ("Messenger Aerial Torpedo"). With a hook mounted above the upper wing, a Messenger [AS68533] piloted by Lt Rex K Stoner "landed" on a trapeze suspended from the D-3 Army Air Service airship in the first successful contact between an airplane and an airship while in flight, 9/18/23, over Langley Field VA (SEE ALSO Consolidated N2Y-1, Curtiss F9C, Vought UO-1, Waco XJW-1 in similar roles). Sperry lost his life on 12/13/23, crashing in the English Channel while demonstrating this plane, which was later rebuilt and modified by Clarence Chamberlin in 1928 for use in demonstrations to publicize lightplane aviation. Several ex-military aircraft appeared later in civil roles, as well.

Colt 190 1958 = Revival of Luscombe Gullwing (qv) with similar data. Don Luscombe (1941). Projected base price $7,995; POP: production planned, but none was built.

    Spibec's original intent was to experiment with fiberglass in lightplane construction, but poor sales of a fiberglass model introduced by Taylorcraft compelled the company to cancel its plans. Colt 190 design rights and fuselage, wing alignment, and gear jigs were purchased for $30,000, according to Carroll S Bechtel, one of Spibec's three owners. By 1958 the prototype had been flown more than 350 hours. Engineering data necessary for FAA approval, with the exception of static wing-loading tests, had been completed. Although with no firm orders, Bechtel production schedule called for 50 Colts the first year (1960) and another 50 the second year at one of several airports in the Philadelphia area, with subsequent output depending on demand for the plane. Spibec's goal was to incorporate as Colt Aviation & Engr Corp. (— Ron Dupas 3/21/01)

"We soon saw that the helicopter had no future and dropped it. The helicopter does with great labor only what the balloon does without labor, and is no more fitted than the balloon for rapid horizontal flight. If its engine stops, it must fall with deathly violence, for it can neither glide like the aeroplane or float like the balloon. The helicopter is much easier to design than the aeroplane, but is worthless when done." — Wilbur Wright, 1909
