Cadet STF 1998 = 2pClwM rg; 100hp Continental O-200. Scratch-built replication of Culver Cadet with steel-tube fuselage (that "STF" in the model name) and fiberglass cowling; similar specs. Plans offered to home-builders for $230. POP: 1 prototype [N48TY].
Special(Chicago) 1930 = 2pOB; 325hp Wright J-5, also J-6; span: 35'0" length: 22'4". Built by Laird, brother of Matty Laird, for John L Patten of Evanston IL. [NR10705] c/n 103. Charlie Laird established Aircraft Engineering (unrelated to the parent company for ACE biplane) in Chicago after he left Wichita in 1930, also had a hand in the Greer College Bryan-Laird B-1B [516K].
(C J) Lake Submarine Co, Bridgeport CT.
c.1909 = One of several classified in 1909 Jane's as an "Air Sucker," described only as having hollow curved surfaces, on which "heated elastic fluid" is discharged, and that "considerable progress has now been made." A flying submarine? Intriguing, to say the least.
This is a very odd one. Swallow C-165 [431N] was a monoplane with a Wright radial. This [431N] was a biplane with a Hisso engine. I looked deeply into the registers and found that C-165 was registered 1929-33, while C-1 was registered 1934-36. It sounds unbelievable, but Dan Lake must have taken over the [431N] registration when C-165 (which he designed) was scrapped and used it for some nostalgic Hisso biplane. Or is it really possible he used the remains of C-165 to build this biplane? What for? Talk about recession! ( Lennart Johnsson 2/23/99)
Designed by Dan Lake, and built Oct 1929 by Swallow with a 165hp Wright as C-165 [X431N] c/n 1, relicensed as [431N] Oct 1930. Sold to Dan Lake in Oct 1933 by the receivers of Swallow. The company name could not be used, so Lake used his own name and changed the model to C-1 after switching to the 150hp Hisso. Sold May 1935 to Stanley Ball of Wichita, reg cancelled 6/1/36, and no further info was found. ( John M Jarratt 2/15/06)

H-2, -3, -4 1944 = 1pCH rg; 85hp Pobjoy R; span: 27'0" rotor: 16'0" length: 15'0" load: 186# v: 100/x/0. Fred Landgraf; ff: 11/2/44. Twin overlapping rotors on wingform pylon, retractable landing gear. $2,300; POP: 1 [X21762], produced as military evaluation prototype, damaged in a test flight. Company, beset by financial problems, cancelled development of 3p H-3 and 5-8p H-4, and auctioned its design and tooling in 1949, with the remains of the prototype going for $50.
Helicopter 1908 = Described only as having a single 40'x20' plane in the center of a horizontal screw 16' in diameter. "The screw sucks air from above, compresses it, and discharges it underneath from special cups at 250 times per minute." Jane's reported that Lane flew this for 1.5 miles on 9/8/1908, using only hand- and foot-power, but specs show it having a 36hp motor.
Helicopter 1929 = 1pOH; 150hp Hisso A; rotor: 26'0". Helical vane arrangements with myriad wires replaced wings and stabilizers; heavily-modified Curtiss JN-4D fuselage. US patent #1,694,880 in 1928. Rotor was driven by a disc drive, with friction providing speed control. Plane was apparently built, but flight info, if any, was unrecorded.
1910 = A triangular wing, span: 20'0" length: 26'0", with trailing-edge ailerons. Powered by a 25hp motor driving two props in a tandem pusher-tractor arrangement; four-wheel undercarriage. Reportedly made a few successful flights.
Aerodrome 1903 = 1pOmwM; 53hp radial motor designed by Stephen Balzer; span: 48'5" length: 52'5". Two tandem wings; designed for catapult launch from a houseboat. Built at the Smithsonian Institution with a $50,000 government grant, attempts at flight on 10/7 and 12/8/1903 (p: Charles Manly), both failed. Notable for his early experiments with steam-driven model aircraft, achieving flight in 1896, it wasn't until nine years after Langley's death that his Aerodrome, replicated and modified considerably, and powered by an 80hp Curtiss, was successfully flown by Glenn Curtiss at Lake Keuka NY on 10/25/14. The Wrights contested this demonstration as irrelevant, that the ship was really an improved Curtiss redesign.

Twin (2-4-65/90), NL-1 1942 (ATC 755) = 2-4pClwM; two 65hp Franklin 4AC; span: 35'2" length: 20'8" (?>20'6") load: 985# (?>890#) v: 135/120/50 (?>142/125/46) range: 400 (?>600) ceiling: 13,300' (?>15,000') (disparities are likely between preliminary estimates and actual flight test results, but which are which is unresolved). Arthur Draper, Martin Jensen. The name honored aviation pioneer Samuel P Langley for his early attempts at flight. Take-off in 200'. Second version (aka 29-90) had 90hp Franklin (v: 150/135/55 range: 450). Vidal plastic-bonded mahogany plywood construction. WW2 interrupted production. $8,500; POP: 2 [NX29099, NC/N51706]. The latter went to USN as XNL-1 , then was sold as war surplus. After a crash-landing c.1965, its remains, along with parts of a Stinson Voyager, were rebuilt into an experimental aircraft and renamed Pierce Arrow [N6622A] (no relation to 1926 Pierce Arrow).
Edward H Lanier and son (Edward M), Miami and Jacksonville FL, Covington KY. 1943: (E M) Lanier Aircraft Corp, Marlton NJ.
1908-22 - Of interest is that the elder Lanier was also inventor of the ice cream cone, which he created while an exhibitor at the 1898 Columbian Exposition in Chicago. Although he had a profitable business selling patented cone-making machines, his real fascination was with flight.
NOTE: if interested in Lanier's theories and applications, an incredibly detailed and scholarly 32-page research project is presently (2007) online as a downloadable PDF file. A 23-page version is also available in HTML format via Google search but lacks all graphics pertaining to the text.
110 Paraplane Commuter PL-8 1958 = 1-2pClwM; 150hp Lycoming O-320; span: 20'7" length: 21'5" load: 500# v: 165/151/30 range: 625 ceiling: 23,000'. Controllable slow-flight at 20-25 mph; take-off and land in 60'. [N4157A]. (The name, Paraplane, fell out of copyright and was adopted for powered parachutes c.2000.)
120 Paraplane I, Paraplane II 1949 = 1pClwM; 90hp Continental A-90; span: 20'5" length: 22'0" load (prototype): 455# v: 120/30-120/28; ff: ?? (p: Leo Riley). POP: 1 test-bed used by Office of Naval Research in STOL evaluation [N9060H]. Inverted "Vacucell" gull-wing with an air scoop below and vacuum-slots on topoperated by a hand-crank in the cockpitenabled slow flight at 19mph, take-off in 100', a 30° climb angle and 40° descent angle, and was spin- and stall-proof. Modified Paraplane II showed up in 1949 with a 22'6" wing and was capable of nearly hovering.
443 Paraplane 1949 = Little data were found, but this was apparently a larger, possibly high-wing, reconstruction of the previous with 180hp Lycoming O-320; v: 171/x/30. POP: 1 [N9060H] (transferred from 120 Paraplane?). Project abandoned c.1955 after failing to attract a market.
Vacuplane 1928-33 - A series of experiments to explore Lanier's ideas on low-speed flight. Relative US patents from 1930-33: #1,750,529, #1,779,005, #1,803,805, #1,813,627, #1,866,214, and #1,913,809. The idea was to adopt the vacuum principle for inherent stability, especially at stalling conditions. Low speed was achieved by placing an upwardly-open concave cell ("vacuum cell") in the center section of the aircraft, most often blending into the fuselage. Slots were also involved. Hence reduced air pressure evolved in the cell which, of course, had a positive influence on the lift. Most Vacuplanes involved the University of Miami aeronautics department and its director, Prof F H Given, to some degreedetails are sketchy. Vacuplane documentation is chaotic, and likely no one will ever sort it out, so the following information on the XLs should be regarded as a mixture of facts with some added educated guesses. ( Lennart Johnsson)
XL-1 1928 = 1pOlwM; Anzani; span: 8'10"(?). The wings were spaced away from the fuselage to allow the air to flow against the vacuum cell.  c/n 1.
XL-2 1930 = 1pCmwM; 85hp LeBlond 5DF. Here the vacuum cell was mounted as a separate box on top of the fuselage. Full-cantilever wing with a span of at least 25', reportedly a modified Durand 13 airfoil. Twin fins and rudders. Pilot in an enclosed cabin under the wing. [X816Y] c/n XL-2.
XL-3 c.1931 = 1pChwM; span: 13'10" v: 90/x/25; take-off in about 50'.
XL-4 1931 = 1pChwM; LeBlond. XL-3 modified with stabilizing wingtip "winglets"; v: 110/x/25. The wing was mounted as a parasol on top of a central pillar which also housed the pilot.  c/n X-141.
LVF (XL-5) 1932 = 1p or 2pOmwM; 36hp Aeronca; span: 14'4" load: 225# v: 96/80/30 range: 250. Take-off run: 90'. A number of pilots found it stable enough not to slip or dive in a stall. In landing it had a tendency to favor a steep descent with control maintained at minimum forward speed. [X12865] c/n XL-5. Some data refer to it as XL-5> from its c/n. A mysterious, Roman-numbered XL-III referred to in some documents might be identical with this one.

Orville G Barnum and Lansing (Ed) Ratelle, Portland OR.
L II 1919 = 1pOB; 350hp Packard 1A. POP: 2 to Air Service for evaluation [AS40034, 40036]; contracts for 2 more were assigned but not built [AS40036, 40037].
Variable Speed Aeroplane 1918 = 1pOB. Little data uncovered about this rather modern-looking creation, but one photo shows a monocoque fuselage and a three-quarter-span beam-type bracing on the top wing. Likely an OX-5 or Hisso for power. Another photo in a magazine ad shows a similar plane with a less-rounded fuselage and with that truss arrangement duplicated on the underside of the lower wing.

Became known as a United Lark, and is one of the snarls that has yet to be sufficiently untangledAAHS E-suffix register has it as a cabin monoplane, which could be a typo.
Speed Bird C 1953 = 2pChwM; 65hp Continental C-65; span: 12'0" (chord: 3'). Modified Taylorcraft with almost no wing to speak of; flight data unknown. [X38C].
My father (Sheridan Hale) said he was at the airport when Larson flew the Speed Bird at Buchanan Field (Concord). He said it took a long time to get off, and Merle flew it around the pattern. One of the pistons was tight and, on downwind, the engine froze. Larson tried to stretch the glide, but didn't make it. The plane crashed, and they ran over to get him out. The landing gears were real strong on the old Taylorcrafts and the plane had buckled in the middle, trapping Larson in the cabin. He said they picked up the tail, unbent it a bit, and Merle climbed out. ( Ken Hale 7/17/00)

[N819N] is one of the original Roza creations of the early '30s, and it was acquired by Franklin Aircraft Co, who modified it a prototype for their Sport 90. It was purchased by Lasley c.1935. who built and installed Peyton Autry-designed wings, then sold it to Lloyd Gabriel. After a crash, it was rebuilt in 1953, reportedly with 125hp Continental, then crashed to destruction in 1957 while buzzing a house.

Twin-boom, twin-tail pusher with a two-wheel tandem gear (because Goodyear rules said planes had to have two wheels), which was replaced by a tricycle gear in 1950.
George R Lawrence, Chicago IL. 1915: Lawrence-(Harry S) Lewis Aeroplane Co, Chicago.
-Lewis A-1, -2, -4 1915 = 2pOBAm; 50hp Kirkham C-4; load: 700#+. Cockpit was enclosed deep in a covered fuselage that looked vaguely like an early Loening design. Made more than 150 successful flights. Advertised as a "speed type," flying "without ailerons, wing warp, or other means of manual control," leaving us to wonder how it was steered. POP: about 3. Basic differences in subsequent A-2 and -4 were changes in engines and radiators. SEE Lawrence-Lewis in detail.
-Lewis B-1 1916 = OBAm; Hall-Scott. Advertised as a "load-carrying type," an extension of A-1, it never went into production.

Triple-tail, quad landing gear; plywood-covered Pullman fuselage, 6'6" wide and 7'0" high, included panorama windows in front. Built in sections in a loft at the Cream Sash & Door Co, Milwaukee, assembled at Wisconsin State Fairgrounds (often seen in error as Air-Liner). POP: 1; the first US multi-engine commercial airliner.
L-4 Air-Line aka Midnight Air-Liner 1921 = 34p tri-motor version of the C-2 with 124'0" span; ff: 5/8/21. Would have been the first US airliner capable of operating at night as a sleeper, it had berths and a white-enameled lavatory, even a shower with hot and cold water! POP: 1, dismantled after being badly damaged on its test flight when it ran into a tree.
MT-2 1918 = 2pOB; 100hp Hall-Scott A4; span: 39'0" length: 25'0" v: 90/x/40; ff: 5/2/18 (p: George Puffles). POP: 1 prototype built for military tests . An Air Service order for 100 planes was received just before the war ended, but was cancelled. The prototype kept flying until an inexperienced 17-year-old pilot totaled it in a crash at New Sweden ME in 1931; he was unhurt.
Pursuit 1918 - 1pOB fighter design with 180hp Hisso; never produced. Lawson's projections for Army consideration was to accompany this plane with a series of floating landing fields across the Atlantic. The idea was rejected as too fanciful.
The genius of Alfred Lawson
Relatively unknown in the annals of aviation history, Lawson might be described as an eccentric genius, one well ahead of his time. Beside the mentions above, some of his accomplishments worthy of note were:
(1) Publisher of Fly magazine, 1908-09, and Aircraft, 1910-17; (2) National League baseball pitcher, 1890s; (3) invented the lighting system for night baseball, 1901; (4) author and editor of several aeronautics books; (5) first to devise sleeping berths, airborne bathrooms, heated cabins, and heated rudder pedals for open-cockpit planes; (6) first to offer passengers night flights; (7) US patent #1,568,855 in 1925 for his passenger compartment design; (8) proposed transatlantic flight in 1918 by placing a string of floating airports between USA and Europe; (9) proposed a transcontinental air route; (10) proposed an airborne post office; and last, but certainly not the least, (11) coined the word "Aircraft" and trademarked it in 1908, but it fell into generic use after appearing lower-case in Webster's Dictionary of 1912 ... where he worked as Aeronautics Editor.

Lee Inman School of Flying, Eugene OR. 11/10/30: Operations sold to Springfield School of Aviation.
L-1P-S 1930 = 1pOM; 37hp Szekely. POP: 1 [631W=N631] c/n 4 (the reg was amended when its engine was changed). Was the model designation for this home-built a deliberate visual play on words, or did L(ee)-1P(lace)-S(zekely) just work out that way on its own as "LIPS"?
I now own and am in the process of restoring the only existing Lee L-1P-S. It was built in 1930 by the Lee Inman School of aeronautics in Eugene OR, originally with a 37hp Szekely engine. In the early '50s it was refitted with a C-65 by Darrel DeLong and was flown to many early EAA events on the West Coast. Log books show that the airframe had over 2,200 hrs since 1930.

Performance Aircraft Inc (pres: Jeff Ackland), Olathe KS. 2002: Legend Aircraft Inc.
1996 = 2pClwM rg; 575hp V-8; span: 25'6" length: 25'0" load: 1000#. Tandem cockpits under a bubble canopy; tri-gear, Fowler flaps. Prototype [N620L].
In Feb 2002, the turbine Legend assets were purchased from Jeff Ackland of Performance Aircraft and incorporated under the new name, Legend Aircraft Inc, by Lanny Rundell, who is also owner/operator of Mid-South Custom Craft (dba Southern Air) for the past 10 years. He worked for Stoddard Hamilton, builder of the Glasair II-S-RG prototype. ( Friedrich Huggler 12/30/02)
1921 = 1pOH; two 100hp Gnôme; rotors: 18'0". Empty wt: 1500#. An early application of the tilt-rotor configuration. Each two lateral rotor units consisted of a set of coaxial counter-rotating screws located at either end of a mast. The mast pivoted to incline the rotor assemblies. The helicopter used some form of compressed air system for "automatic" control, along with a conventional rudder. It also failed to fly, according to a found report.
Information in a 1921 Austrian magazine translates as: "In the Speedway-Wharf1 in Chicago a new flying machine was shown these days to the public by the three brothers Leineweber, all of them engineers. This new flying machine was a realization of an invention by their father, Hermann Leineweber2, 16 years earlier. It is a flying machine with four propellers, which are mounted in pairs left and right of the fuselage. The machine is able to ascend and descend steeply, which makes it possible to land and start from quite small places. The flying machine is powered, without engines, with pressure air that drives the propellers4. There are no wings, and the machine should fly very evenly and undisturbed."
(1) "Speedway-Wharf" is the best I could do, but I am not sureperhaps it, or something close to that, exists or existed. I don't think Austrians in 1921 had any idea of Chicago and its geography. (2) Hermann Leineweber and his invention are traced to US Patent #1,064,232 "Airship," filed on 13 Nov 1909. He is described as residing in South Chicago, in the county of Cook and state of Illinois, and the patent is not about airships, but about a propeller-driven helicopter type. (3) There is no hint in the text that the machine can climb vertically. It leaves the matter with the word "steeply." (4) That business about the engine is not clear as it is empathically said the machine was not powered by a pneumatic
engine, while the impression is that it was driven by a pneumatic engine. Although I found some information about Hermann, I found nothing about the Leineweber machine pictured. ( Kees Kort 12/21/07)

Proud Bird c.1975 = 1pClwM. Formula 1 racer (p: Fred Wofford). [N9SL].
(First name unrecorded) Lemp, Augusta GA.
B 1916 = 2pOB; Wright 4 pusher. Modified Wright B with wheel-type control and wing-warping, Model B rudderscuriously antiquated for the date; later with revised wingtips, trailing-edge ailerons, and a Rausenberger V-8 motor. Used initially for training, later for exhibition; flown until 1925, when Lemp purchased and donated it to Chicago Museum of Science, who in turn handed it to USAF Museum.
1927 = 2pOB; LeRhône rotary with a Thomas-Morse-type flared cowling; span: 25'0" length: 24'0". All-metal construction with no external wire bracing. POP: 1 . A Rick Allen abstract shows that the "Lenert Metal Biplane" crashed Apr 1927.
C 1929 = 3pOB; 90hp Curtiss OX-5; span: 31'0" length: 25'0" load: 1000# v: 140/120/35 range: 500. $2,950; POP: 1 [X866N] c/n 1. All-metal ("All but the tires," ads claimed, later adding as an afterthought: "and control stick"), Dural corrugated skin. Repowered with 165hp Continental A-70 in 1930 to sell for $5,500. Why C has a lower c/n than B is as odd as why the 1927 plane (A?) has no recorded c/n.

Auto-Airplane 1933 = More inventiveness from Mr Lewis, this one a propellerless whirling dervish with flapping wings, as well as wheels to drive to the grocery store. Never built in finality, it rated this full page in a popular magazine at least.
Gray Goose (MD-1) 1930 = 2pOhwM; 165hp Wright J-6 pusher; span 30'0" length: 20'0". Fred Landgraf (seen misspelled as Langraff and Langgraff). Deep-chord, flexible parasol wing; triple tail. Horizontally-mounted motor in the fuselage drove two outboard, fabric-covered propellers (also referred to as "rotating wings") via reduction gears and shafts, turning them at 350rpm. POP: 2; the first one, as MD-1 with 40hp Ford A [355V] c/n A-1, vibrated itself to pieces when first cranked up. The second one [x], with a sizable increase in horsepower, flew in 1933 to a claimed altitude of 14 inches (as recorded on a barograph?), but overheating problems brought an abrupt end to test flights. A connection between this and the 1936 Gray Goose entry (qv) could not be not verified, despite some interweavings.
Gray Goose 1931 = In light of recent information, this seems to be the "other" Gray Goose (qv) despite its Lewis-American credit line. From an article in AAHS Journal (Winter 1979) about Bill McMahon, who worked with Lewis-American c.1933-35: "Bill considered it a shady operation because its primary purpose was the selling of stock ... although two different designs were actually built. The first of these, the Gray Goose, never did fly ... vibrated itself to death ... then they hired Fred Landgraf to produce a second Gray Goose." This might also have been model A, which flew one circuit of the airfield and landed when the buried engine overheated. However, if accurate, that places Landgraf in the picture much later than other documented references. The apparent relationship of this and the markedly similar Gray Goose has yet to be resolved.

1928: Midwest Aircraft Corp, St Cloud MN. 1928: North Star Aircraft Corp (fdr: Willard Hoseas Mohlar).
100-HM4a, H-400 1928 = 3pO/CB; 180hp Wright-Hisso E; span: 30'10" (?>31'0") length: 22'10" load: c.1240# v: 135/125/40-45. Front cockpit was enclosed into a side-by-side cabin. POP: 1 [X5470] c/n 186, or [5505(?)] or [X7537]; H-400 was for a planned 400hp Liberty 12.
This one gets more space than it really deserves, but it is noteworthy as its episodic drama plays out and mysteries surface. In March 1928, Mohlar showed up, a colorful con-artist representing himself as a Captain in the Lafayette Escadrille and a chief designer with American Eagle Colater investigation showed he had no flying experience, no war service, only a marginal knowledge of mechanics, and worked for a few weeks as a junior draftsman for American Eagle. He formed a company and produced one plane, either a direct copy of an American Eagle, or a modification of one with factory c/n 186it was licensed , but abstracts for that license show a path of ownership 1928-41 through Kansas, Nebraska, and Ohio. [X7537] appears on a 1929 record credited to North Star (and showing a Warner Scarab). The year 1929 is notable since the company was history by the end of 1928. North Star was on shaky footing since its formation, and it didn't help when Mohlar cleaned out the safe in September and headed for higher ground, appearing in October as manager of a nonexistent Chicago Aeronautical Service in that city. Liberty Bell, then in the hands of creditors and dubbed Spirit of St Cloud, finally got airborne on 10/15/28 (p: Lester Coyle), only to stall on take-off and crash tail-first, ostensibly slamming the lid on North Star. A CAA abstract has it as sold 10/12/28three days before its first-flight date!for $600. It must have been rebuilt, for it was resold 11/27/28 for $500, and again 1/23/29 (no price stated), with installation of a 90hp OX-5 on 7/21/29, finally reported to DoC as having been dismantled 10/4/30. A conflicting letter, from a crop-duster operation to DoC on 4/26/30, explained that the plane was destroyed "in a cyclone last June" (1929!). All of the foregoing took place in Minnesota, but the story is not ended. For those who haven't dropped out of the chase by now, SEE Mohlar. ( K O Eckland)

One was resurrected as 'DGA-5' by Benny Howard and used briefly in an air show comedy act, but unlikely flown by him. It crashed on the way to Indianapolis for a show c. 1933, killing Bob Moore, and Benny was charged with a number of violations. It was a subject he would not talk about and the true story of the original DGA-5 is virtually unknown since he covered his tracks by re-applying the DGA-5 designation to Howard Mike in later years.

A-7 Corsair II - 1pCmwM rg jet attack aircraft based on F8U with shorter fuselage and redesigned wing with reduced sweepback.
A-7C, TA-7C 1968 = As A-7B, but with a multi-barrel 20mm cannon. POP: 67 [156734/156800]. TA-7C was tandem 2p training conversions of A-7B and -7C; length: 48'8". POP: 90 [156801/156890].
The A-7C was not supposed to be. The "original plan" was for the Navy to develop a two-seat TA-7C by lengthening and upgrading the A-7B. About that same time the Navy was negotiating the development of A-7E (as the USAF was doing with A-7D) using the Rolls-Royce Spey engine (the Spey having more oomph than the P&W TF30). The A-7E was to have the new AN/APQ-126 radar, improved avionics (new HUD, improved Inertial Navigation System, great AN/ASU-99 Projected Map Display System), new weapons control system and the six-barrel 20mm M61-A1 "Vulcan" cannon in place of A-7B's two single-barrel guns. Through a series of high-level misadventures, TF41 engines were way behind the aircraft in the production cycle. The A-7E fleet introduction had been advanced some 18 months to get it into the Viet Nam conflict sooner. A-7E airframes (with all the electronic improvements mentioned) were rolling off the production line with no TF41s to install. Thus some 67 aircraft had the old TF30 installed, and things got confusing. There was period when there were two different kinds of A-7Es in the Fleet with different cockpit configurations, engine and hydraulic instruments, as well as different engine operating and emergency procedures. In late '71 and into '72, the brass seemed content to have that (dangerous) situation continue. Eventually, by late '72 or early '73, good sense prevailed, and the TF30-powered A-7Es were designated as A-7Cs. It was those Cs (and some Bs) that were then converted to TA-7Cs. Some TA-7Cs were then converted to EA-7L electronic warfare/jammer aircraft used by VAQ-33 and VAQ-34 for fleet EW training. In spite of everything the Navy brass and higher-ups did, the A-7E went on to become a fine and well-liked aircraft with a distinguished combat record. ( Jim Bohannan 1/19/00)

c.1950 = 1pOB; 90hp Warner Scarab; span: 16'0" length: 13'0" v: 150/130/55. The engine looked oversized on this diminutive biplane, claimed to be stressed for 12 Gs. [N1553M].
H N Double Eagle 195? = 2pChwM rg; two Continental O-200. [N4921]. Livingston built about 25 aircraft in the Experimental category since 1933.
"Who valued life more highly, the aviators who spent it on the art they loved, or the misers who doled it out like pennies through their antlike days? I decided if I could fly for ten years before I was killed in a crash, it would be a worthwhile trade for an ordinary lifetime." Charles Lindbergh
