Laird, Laird-Swallow, Laird-Turner


Laird

Charles L Laird, Chicago IL.

Special 1930 = 2pOB; 325hp Wright J-5, also J-6; span: 35'0" length: 22'4". Built for John L Patten of Evanston IL. [NR10705] c/n 103.
    It seems he set up Aircraft Engineering in Chicago 1930 after he left Wichita and built the B-2. He also had a hand in the Greer College Bryan-Laird B-1B [516K]. (— John M Jarratt 9/23/02)


Lake

(C J) Lake Submarine Co, Bridgeport CT.

INFORMATION NEEDED
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.

Lake (aka Dan Lake)

Dan Lake, Lake City KS.

C-1 1929 = 4pCB; 150hp Hisso A. Modified 165 Swallow. [X431N].

    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)

Lane

Lane Automatous Air-Ship Co, San Francisco CA.

INFORMATION NEEDED
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.

Lang

Frank Lang, Lockport IL.

Sport c. 1968 = 1pOlwM; Menasco.


Langdon

Jesse E Langdon, Bell CA.

  Langdon Side-view

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.


Lange-Billard

Location unknown.

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.


Langhurst

Stuka 1978 = 2pClwM; 220hp Avco Lycoming GO-435; span: 32'6" length: 24'0" load: 575; ff: 7/19/78. 7/10-scale replica German Stuka dive bomber. [N87LL].


Langley

Dr Samuel P Langley, Washington DC.

  Langley Aerodrome Glenn Curtiss replica under construction and in flight, 1914
  Langley Aerodrome Curtiss replica from old postcards

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 (as contested by the Wright brothers), and powered by an 80hp Curtiss, was successfully flown by Glenn Curtiss at Lake Keuka NY on 10/25/14.

Langley

1940: Langley Aircraft Corp (pres: Caleb S Bragg), Port Washington NY. 1942: Acquired by Andover-Kent Aviation Co (pres: J J Brooks), New Brunswick NJ, but WW2 curtailed activity. 1947: Langley Aviation Co, New York NY.

  Langley XNL-1 [39056] (Paul McLaughlin coll)
  Langley Twin Color pic shows why it was called "an exquisite piece of furniture" (Paul McLaughlin coll)

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 [39056], 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).


Lanier

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 cone-making machines, his real fascination was with flight, and he is said to have built several aircraft during this period, details of which are unknown.

  Lanier Paraplane PL-8 [N4157A] (Lanier via Ron Dupas coll)

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'. Take-off and land in 60'. [N4157A].

  Lanier Paraplane II [N9060H] (Frank Rezich coll)

120 Paraplane I, Paraplane II 1949 = 1pClwM; 90hp Continental A-90; v: 120/x/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 top, enabled slow flight at 19mph, take-off in 100', a 30-degree climb 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 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 degree — details are sketchy. The Vacuplane documentation is chaos, 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 educated guesses. (— Lennart Johnsson)

XL-1 1928 = 1pOlM; Anzani; span: 8'10"(?). The wings were spaced away from the fuselage to allow the air to flow against the vacuum cell. [3505] 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. [11512] 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.


Lansing

C R Lansing, Warren OH.

1931 = 2pOM; 40hp Ford. [12830].


Lansing

Orville G Barnum and Lansing (Ed) Ratelle, Portland OR.

1T 1931 = 2pOB; 45hp Szekely SR-3; span: 20'0"; ff: 9/x/31. Tail design "prevented flat spins." [10677] c/n 1000.


Lanzius

  Lanzius L II [AS40036]

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.


La Porte

La Porte Aircraft Co, La Porte IN.

1938 = 2pChwM; 45hp Continental A-45. Vernon Payne.


Lardin

Arthur Lardin, W A McCurdy, E Smith, New Castle DE.

Lark

1927: Lark Aircraft Co (pres: Romer G Weyant), 217 E Lincoln, Wichita KS. 1928: United Aircraft Corp (qv).

1927 = 6pO/CB; 225hp Wright J-5. Fred R McConigal. 4p cabin, 2p open cockpit; very likely a redesignation of Commercial Sunbeam. POP: 1 [X137E] c/n 1, maybe more, but not found. Became known as a United Lark, and is one of the snarls that has yet to be sufficiently untangled — AAHS E-suffix register has it as a cabin monoplane, which could be a typo.

  Larson D-1 [NX4840V] (William T Larkins)

D-1 Agricultural Biplane 1955 = 1pOB; 225hp Lycoming R-680; span: (upper) 30'0" (lower) 33'0" length: 27'0" load: 1700# v: x/90/40; ff: 5/30/55. Take-off run: 200'. Half-fuselage of welded steel tubing; twin tails on framework boom. Sheet-metal wings, all four panels of equal size. Standard Ford automobile wheels and brakes. [X4840V].

F-12 Baby 1961 = Sportplane. 1pOB; 85hp Continental C-85; span: 17'0" length: 17'0" load: 300# v: 130/110/x..

  Larson Helicopter [N7352C] (William T Larkins)

Helicopter 1958 = 1pOH; 85hp Continental C-85; no data. [N7352C].

  Larson Speed Bird [X38C]

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 CA). 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)

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 quickly fell into generic use after generically appearing in Webster's Dictionary of 1912, where he worked as Aeronautics Editor.

Lee

Lee Aircraft Co, Napoleon OH.

L-1P-S 1930 = 1pOM; 40hp Szekely. [631W=631] c/n 4. 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? A 2p design L-2 followed (Continental A-40), but was never constructed, and there was no found info on possible c/ns 1 through 3. The reg was amended to [631] when its engine was changed.

    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 has over 2,200 hrs since 1930.

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 (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 have been model A, which flew one circuit of the airfield and landed when the buried engine overheated. However, if accurate, this 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.

  Liberty Bell [X5470] (V J Berinati coll)

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 Co — later 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 186 — it was licensed [5505], 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. An abstract shows it as sold 10/12/28 — three days before its first-flight date! — for $600. It must have been rebuilt, for it was resold Nov 27 for $500, and again 1/23/29 (no price stated), with installation of a 90hp OX-5 on July 21, finally reported to DoC as having been dismantled 10/4/30. A conflicting letter of 4/26/30, from a crop-duster operation to DoC, 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)

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)

"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
