19 October 1908: From the grounds of the Château de Bagatelle, Paris, France, Eugène Welferinger (1872–1936) made the first flight of the Société d’aviation Antoinette monoplane, the Antoinette IV.

A single-place, single-engine airplane, the Antoinette IV was one the first successful monoplanes. American Machinist described it as a “purely racing machine.”

The airplane and its V-8 engine were designed by Léon Levavasseur. It was modified a number of times, as was its sister ship, the Antoinette V.

“Left front view of Société Antoinette ‘Antoinette IV’ on the ground. This version is of ‘Antoinette IV’ is fitted with two large in-line wheels, substantial mid-wing skids, and a paddle-type propeller. Designer Léon Levavasseur stands at left (bearded man wearing dark vest and cap). Issy-les-Moulineaux, Paris, France, November 1908.” (M. Rol & Cie, 4 Rue Richer, Paris/Library of Congress)

Augustus Post, Secretary of the Aero Club of America, wrote in the weekly technical publication, American Machinist:

     M. Lavavasseur considered that the monoplane offered the advantages of simplicity of form, natural stability, and was easier to construct; that is to say, that the thrust of the motor required for flight was less under the same conditions of speed and weight.

     The “Antoinette” is particularly interesting on account of the manner in which the problems have been studied and the great amount of thought that has been given to them. The machine is perhaps without question the most finely finished of those in its class, shows the most careful workmanship in its most minute detail, and presents more new and original features than any of the other machines which may be compared with it. It also provides a comfortable cockpit for the aviator, a distinct advantage in long and trying flights.

—American Machinist, Hill Publishing Company, New York, 7 October 1909, Page 608 at Column 2

The Antoinette IV was approximately 11,50 mètres (37.72966 feet) long with a wingspan of 14,80 mètres (48.55643 feet). The leading edge was swept aft 3°. They had a chord of 3 meters (9.8 feet) at the root, tapering to 2 meters (6.6 feet) at the tip. The wing had an angle of incidence of 4° with 6° dihedral. The total surface area was 34 square meters (366 square feet). The weight of the Antoinette IV was 460 kilograms (1,014 pounds) with one hour of fuel. It was capable of reaching 120 kilometers per hour (75 miles per hour).

The airplane was described in contemporary reports as “beautiful” and often mentioned was the very narrow triangular cross section of its fuselage. Different configurations of landing gear were tried, with combinations of skids and wheels, wheels in tandem, and side-by-side. Directional control was created through “wing-warping” as had been used by the Wright Brothers. This was later modified to an aileron system. The tail surfaces were cruciform, with two triangular rudders located above and below the triangular elevator. Flight controls were four hand wheels and two pedals which connected to the control surfaces by cables.

As originally built, the Antoinette IV was powered by a steam-cooled, normally-aspirated, 7.274 liter (443.861 cubic inch displacement) Antoinette 8V 90° overhead valve V-8 engine which produced approximately 45–50 chaval-vapeur (44.4–49.3 horsepower) at 1,400 r.p.m. This engine was considerably smaller and lighter than Levavasseur’s previous V-8s. Because the compression ratio was increased, the aluminum cylinder heads were replaced with forged steel heads. Carburetors were used instead of direct injection, which was prone to clogging. The 8V was a direct-drive engine which turned a propeller with two aluminum blades which were riveted to a steel tube that attached to the engine’s output shaft. The propeller had a diameter of 2.20 meters (7 feet, 2.6 inches). The V-8 engine was 0.750 meters (2 feet, 5.5 inches inches) long, 0.600 meters (1 foot, 11.6 inches) wide and (0.600 meters (1 foot, 11.6  inches) high. It weighed 60 kilograms (132 pounds), dry, and 85 kilograms (187 pounds) in running order.

The engine sold for ₣12,500 (approximately $2,451 U.S. dollars) with delivery expected in 10 months. Antoinette airplanes could be purchased for ₣25,000, or about $4,902 U.S. dollars.

On 19 July 1909, Arthur Louis Hubert Latham, who had been taught to fly by Welféringer, attempted to fly the Antoinette IV across the English Channel, but an engine failure forced it down about 8 miles (13 kilometers) off the French coast.

The airplane remained afloat and Latham was rescued by the French torpedo boat destroyer FS Harpon, but the airplane was severely damaged during the recovery.

Léon Levavasseur was a French engineer, born 8 January 1863 near Cherbourg, France. He invented the 90° V-8 engine, which he patented in 1902. He specialized in lightweight engines, using components designed to be only as strong as was required by their specific use. He developed direct fuel injection and evaporative cooling for internal combustion engines.

His company, Société d’aviation Antoinette, and its products, were named for the daughter of his business partner, Jules Gastambide. The company initially produced lightweight engines for other airplane builders, but began to construct complete airplanes in 1906. Both Levavasseur and Gastambide left Antoinette in 1909 following a disagreement with the board of directors, but they returned five months later. The company failed in 1911.

Levavasseur was appointed Chevalier de la légion d’honneur in 1909.

Léon Levavasseur died in Paris, France, 26 February 1922, at the age of 59 years.

Captain Alfred Gilmer Lamplugh, CBE, FRAeS, MIAeS, MCAI, FRGS (19 October 1895–15 December 1955)

“Aviation in itself is not inherently dangerous. But to an even greater degree than the sea, it is terribly unforgiving of any carelessness, incapacity or neglect.”

Probably every pilot, or aspiring pilot, has read these words in some form. The statement was made by Captain Alfred G. Lamplaugh, Principle Surveyor for The British Aviation Insurance Co., Ltd.

Captain Alfred Gilmer Lamplugh, C.B.E., F.R.Ae.S, M.I.Ae.S., M.C.A.I., F.R.G.S.—nicknamed “Lamps”— was well known and respected in aviation circles in the United Kingdom. He was one of the great (though largely unkown) personalities of the aviation world.

The Journal of the Royal Aeronautical Society reported:

THE DEATH OF CAPTAIN A. G. LAMPLUGH on 15th December 1955, at only sixty years of age is a grievous blow to aviation and one that I personally feel most deeply, for our activities in the aeronautical world brought us together on frequent occasions over a period of many years.

     Captain Alfred Gilmer Lamplugh, C.B.E., F.R.Ae.S., M.C.A.I., F.R.G.S., had been Underwriter and Principal Surveyor of the British Insurance Co. Ltd. since its formation until his retirement and election to its board of directors in September last.

     He was educated at King Edward’s School and Queen’s College, Birmingham. His interests were technical rather than scholastic, however, and he served an apprenticeship with a firm of motor engineers. In 1913 he learned to fly and obtained one of the very early “B” licenses.

     The Great War came and he went into the army, to be seconded later to the R.F.C. He served in that corps and the R.A.F. until 1919.

     It was abroad, in China, that he gained his first experience in insurance. Then home once more, he became Underwriter to the British Aviation Insurance Group, later British Aviation Insurance Co. Ltd., and was introduced to aviation insurance, this group in those days being the only body to undertake such work.

     His interest in almost every aspect of things aeronautical was enormous and far beyond a merely professional one. This interest—and his great abilities—were reflected in the number of positions, mainly honorary in nature, which he filled with success and in many cases for long periods.

     He was a member of the Committee of the Royal Aero Club for nearly thirty years; a memmer of the Council of the Air Registration Board since its inception; an honorary member of the British Airline Pilots’ Association; a member of the International Union of Aviation Insurers; Chairman of the Aviation Insurance Offices Association; and President of the London Gliding Club. In 1943 he was Chairman of the Independent Committee on the Future of Civil Aviation.

     He did much for flying, both in these capacities and in other ways, not least by his services in the field of insurance. It was in recognition of this that he was appointed a Companion of the order of the British Empire.

     “Lamps” made it his business and his pleasure to be at the heart of aeronautical activities, not only getting to know people, but getting to know them well. He was a familiar figure at aviation gatherings of every sort since the early ‘twenties and will be missed by very many of us indeed.

SIR FREDERICK HANDLEY PAGE

J. Laurence Pritchard writes:

     I have a great affection for “Lamps,” and I am glad to be able to express it in the JOURNAL of the Society, of which he was a good friend.

     On September 14, last year, he wrote to me, in reply to a letter of mine about a project of his, “It would be nice to have some stabilizing influence like yours in the show and it was kind of you to write. Your interest has bucked me up a lot.”

     “Lamps” must have known that his chance of carrying out his idea was very small indeed, but his magnificent courage would never allow him not to try, whatever the odds were. I shall always be glad that I was the first to reply to his suggestion, for he was the first to listen to any suggestion of mine when he was on the Council of the Society, and its Honorary Treasurer.

     “Lamps” joined the Society in 1924, and became an Associate Fellow two years later. In 1929 he was made a Fellow.

     On the Council, to which he was first elected in 1933, he was a tower of strength with his direct comments, which were always listened to, and generally agreed upon. It was a tribute to his practical and sane outlook that the year he was elected to the Council, he was asked to serve on the Finance Committee, upon which he served until 1947.

     He was Honorary Treasurer in those difficult years 1941–46 when Councils and Committees were not able to give close consideration to the affairs of the Society, and I wanted what help I could get.

     “Lamps” often dropped in casually in those days, talked about any difficulties I may have had, and just as casually went out saying, All right, chaps, it’ll be done.” It was. Few appreciated how quietly he kept up others’ morale, how shrewdly he summed up all those with whom he came in contact.

     During the War he once gave me a lift in his car into the West Country. Those were the days when all sign posts had been obliterated, post office and village signs blotted out; and driving was difficult. Yet he drove with great assurance, often on minor roads, while we talked of everybody and everything. In his car he had a small portable wireless set, given him in New York, so that he could hear the news wherever he happened to be. Fixed below the dashboard was an aeroplane compass.

     “That’s how I find my way,” he replied cheerily, when I complimented him on his knowledge of all the by-roads.

     When the offices of the Guild of Air Pilots were destroyed I agreed to find room for their staff at 4 Hamilton Place. “Lamps” was one of the Wardens of the Guild and often came in to see how things were going. One day a bomb dropped in Hyde Park and blew in some of the office windows. I had given very definite orders that the moment the sirens sounded their warning all curtains were to be drawn and staff were to keep away from the windows.

     I went round the building, and as I walked up the stairs to the Guild of Air Pilots’ room Lamplugh followed me. He had dashed round to see how things were. One of the girls was sitting in front of her typewriter by a window, the blind not drawn. For disobeying the orders upon which her life might have depended she got no praise but was told sharply where to sit in the future. I expected “Lamps” to say something to me about the way I spoke to someone not on the Society’s staff. All he said was, as we walked away, “Good show, chaps.”

     I believe that when someone tries to assess the personalities of those early years of aviation, that of Alfred Gilmer Lamplugh will rank very highly indeed, for he had the courage and vision when both were required in full measure.

***************

Alfred Gilmer Lamplugh was born at Garton on the Wolds, East Riding of Yorkshire, England, 19 October 1895.  He was the first of three children of Sydney Augustus Lamplugh and Ellen Cecile Gilmer Lamplugh. His younger brother, Air Mechanic 1st Class Sidney Clifford Lamplugh, was killed 6 March 1917, when the airplane on which he was an observer entered a spin and crashed shortly after takeoff. His sister, Joan Frances Mary Elinor Lamplugh, M.B., Ch.B., was a physician and surgeon who ran two medical missions in Rhodesia.

Alfred Lamplugh had apprenticed with the Austin Motor Company. He learned to fly in 1913, and he received Air Ministry B License No. 155.

He enlisted in the 4th Hussars, British Army, on 1 September 1914 and on 22 January 1915 received a commission as a Temporary Second Lieutenant, 8th Battalion, North Staffordshire Regiment. Infantry. He was transferred (“seconded”) to the Royal Flying Corps 12 August 1916. He was trained to fly at the Military School, Birmingham, in a Maurice Farman biplane. Lieutenant Lamplugh received an aviator’s certificate from the Royal Aero Club, 8 December 1916.

He was assigned to the 5th Reserve Squadron. (The R.F.C. became the Royal Air Force on 1 April 1918.) Lieutenant Lamplaugh was deployed to Mesoptamia and according to one source, served as a pilot for T. E. Lawrence (“Lawrence of Arabia”).He was promoted to captain 2 August 1919. On 24 October 1919, Captain Lamplugh was appointed Flying Officer, Royal Air Force.

Flying Officer Alfred Lamplugh married Miss Marie Emily Hugo at King’s Norton, Worcestershire, in December 1919. They would have two sons, Alfred Brian Hugo Lamplugh and Beric Clifford Gordon Lamplugh.

On 29 January, Lamplugh, then employed as an insurance manager, saild aboard S.S. Adriatic from Southampton to New York, arriving there 8 February 1920. He crossed the North American continent by railroad, then sailed across the Pacific to Hong Kong. Mrs. Lamplugh joined him later. They returned to England with their son Brian aboard S.S. Carnarvonshire, arriving 6 March 1923.

In 1922, Flying Officer Lamplugh was transferred to the Reserve of Air Force Officers, in which he remained until relinquishing his commission 30 December 1938. He was permitted to retain his rank.

In the King’s Birthday Honours, 13 June 1946, Lamplugh was appointed a Commander of the Most Excellent Order of the British Empire.

Alfred Lamplugh died at Marylebone, London, England, 15 December 1955. The following day, he was posthumously appointed Officier de l’Ordre de Leopold II by Belgium.

The Rockwell International B-1B Lancer is a supersonic intercontinental bomber capable of performing strategic or tactical missions. It is operated by a flight crew of four.

The B-1B is 147 feet, 2.61 inches (44.8719 meters) long, with the wing span varying from 86 feet, 8.00 inches (26.4160 meters) at 67.5° sweep to 136 feet, 8.17 inches (41.6603 meters) at when fully extended to 15° sweep. It is 33 feet, 7.26 inches (10.2428 meters) high to the top of the vertical fin. The bomber’s empty weight is approximately 180,500 pounds (81,873 kilograms). Its maximum weight in flight is 477,000 pounds (216,634 kilograms). The internal payload is up to 75,000 pounds (34,019 kilograms).

The bomber is powered by four General Electric F101-GE-102 turbofan engines, mounted in two-engine nacelles under the wing roots. These are rated at 17,390 pounds of thrust (17.355 kilonewtons) and produce 30,780 pounds (136.916 kilonewtons) with “augmentation.” The engine has two fan stages, a 9-stage axial-flow compressor and a 3-stage turbine. The F101-GE-102 is 15 feet, 0.7 inches (4.590 meters) long, 4 feet, 7.2 inches (1.402 meters) in diameter and weighs 4,460 pounds (2,023 kilograms).

100 B-1B Lancers were built between 1983 and 1988. As of May 2018, 62 B-1B bombers are in the active Air Force inventory. The Air Force plans upgrades to the aircraft and plans to keep it in service until 2036.

To comply with the START weapons treaty, B-1B 82-0001 was scrapped at Ellsworth Air Force Base, South Dakota, in the mid-1990s.

Brigadier General William Mitchell, Air Service, United States Army, 1879–1936. (United States Air Force)

18 October 1922: At Selfridge Field, near Mount Clemens, Michigan, Assistant Chief of the Air Service Brigadier General William Mitchell set a Fédération Aéronautique Internationale (FAI) World Absolute Speed Record flying a Curtiss R-6 biplane, Air Service serial number A.S. 68564, over a 1 kilometer course at a speed of 358.84 kilometers per hour (222.973 miles per hour).¹

This was the same airplane with which Lieutenant Russell L. Maughan had won the Pulitzer Trophy just three days earlier.

Brigadier General William Mitchell stands in the cockpit of a Thomas Morse pursuit.

Sources vary as to the speed General Mitchell attained, e.g., 222.96 m.p.h., 222.97 m.p.h., 224.28 m.p.h., and 224.4 m.p.h. A contemporary news magazine listed the officially recognized speed as 224.58 miles per hour (361.43 kilometers per hour):

American World’s Speed Record Homologated

The speed record made by General Mitchell, of the American Air Service, on October 18 last year, when he attained a speed of 224.58 m.p.h., has now been homologated by the International Aeronautical Federation.

“Billy” Mitchell had been the senior American air officer in France during World War I. He was a determined advocate for the advancement of military air power and encouraged his officers to compete in air races and attempt to set aviation records to raise the Air Service’ public profile. He gained great notoriety when he bombed and sank several captured German warships to demonstrate the effectiveness of airplanes against ships.

His outspoken advocacy resulted in the famous Court Martial of Billy Mitchell, in which a military court consisting of twelve senior Army officers found Mitchell guilty of insubordination. He was reduced in rank and suspended for five years without pay. Major General Douglas MacArthur (later, General of the Army, a five-star rank) said that the order to serve on the court was “one of the most distasteful orders I ever received.” Mitchell resigned from the Army and continued to advocate for air power. He died in 1936.

After his death, President Franklin D. Roosevelt elevated Billy Mitchell to the rank of Major General on the retired officers list. The North American Aviation B-25 twin-engine medium bomber was named “Mitchell” in recognition of General Mitchell’s efforts to build up the military air capabilities of the United States.

The Curtiss R-6 Racers were single-engine, single seat, fully-braced biplanes with fixed landing gear, developed from the U.S. Navy Curtiss CR. The airplane and its D-12 Conqueror engine were both built by the Curtiss Aeroplane and Motor Co., Garden City, New York. The fuselage was a stressed-skin monocoque, built with two layers of wood veneer covered by a layer of doped fabric. The wings were also built of wood, with plywood skins and fabric-covered ailerons. Surface radiators were used for engine cooling.

Two R-6 Racers were built of the U.S. Army at a cost of $71,000, plus $5,000 for spare parts.

The Curtiss R-6 was 19 feet, 0 inches (5.791 meters) long with a wing span of 19 feet, 0 inches (5.791 meters). It had an empty weight of 2,121 pounds (962 kilograms).

The R-6 was powered by a water-cooled, normally-aspirated 1,145.11-cubic-inch-displacement (18.765 liter) Curtiss D-12 dual overhead cam (DOHC) 60° V-12 engine, which was developed by  Arthur Nutt, based on the earlier Curtiss K-12 which had been designed by Charles B. Kirkham. The D-12 had four valves per cylinder and a compression ratio of 5.7:1, and was rated at 415 horsepower at 2,000 r.p.m., and 460 horsepower at 2,300 r.p.m. During testing, it produced a 475 horsepower at 2,320 r.p.m. using a 50/50 mixture of 95-octane gasoline and benzol. The D-12 was a direct-drive engine and it turned a two-bladed, fixed-pitch, forged aluminum propeller designed by Dr. Sylvanus A. Reed. The Curtiss D-12 was 56¾ inches (1.441 meters) long, 28¼ inches (0.718 meters) wide and 34¾ inches (0.882 meters) high. It weighed 678.25 pounds (307.65 kilograms).

The R-6 racer had a maximum speed of 240 miles per hour (386 kilometers per hour). The service ceiling was 22,000 feet (6,706 meters), and it had a maximum range of 281 miles (452 kilometers).

A.S. 68564 disintegrated in flight at the Pulitzer Trophy Race, 4 October 1924, killing its pilot, Captain Burt E. Skeel.

Charles, Comte de Lambert (1865–1944)

18 October 1909: Charles Alexandre Maurice Joseph Marie Jules Stanislas Jacques Count de Lambert, the first student to successfully complete Wilbur Wright’s aviation school at Pau, Pyrénées-Atlantiques, flew his Wright Model A Flyer from Port Aviation (Juvisy-sur-Orge), Viry-Châtillon (in the outskirts of Paris), the World’s first airport, to the Eiffel Tower.

The Comte de Lambert departed Port Aviation at 4:36 p.m. He circled the Tower at an altitude of 400 meters (about 1,300 feet) and then returned to Pau, located on the northern edge of the Pyrenees.

The flight covered approximately 48 kilometers (30 miles) with an elapsed time of 49 minutes, 39 seconds.

Comte de Lambert’s flight coincided with an evening banquet celebrating a two-week “Grande Quinzaine de l’Aviation de Paris“. L’Aéroclub de France awarded him a Gold Medal for his achievement, and France appointed him Chevalier de la Légion d’Honneur.

The Wright Model A, produced from 1907 to 1909, was the world’s first series production airplane. It was slightly larger and heavier than the Wright Flyer III which had preceded it. It was a two-place, single-engine canard biplane built of a wooden framework braced with wires and covered with muslin fabric. A new system of flight controls allowed the pilot to sit upright rather than lying prone on the lower wing.

The dual horizontal elevators were placed forward and the dual vertical rudders aft. The biplane was 31 feet (9.449 meters) long with a wingspan of 41 feet (12.497 meters). The wings had a chord of 6.6 feet, and vertical separation of 6 feet. The airplane had an empty weight of approximately 800 pounds (363 kilograms).

A water-cooled 240.5 cubic-inch-displacement (3.940 liter) Wright inline four-cylinder gasoline engine produced 32 horsepower at 1,310 r.p.m. Two 8½ foot (2.591 meters) diameter, two-bladed, counter-rotating propellers, driven by a chain drive, are mounted behind the wings in pusher configuration. They turned 445 r.p.m.

The Wright Model A  could fly 37 miles per hour (kilometers per hour).
