Henry Farman 1907

[8April2017]
Extracts, mainly from Le Matin, on Henry Farman’s flying, autumn 1907.

Though first a comment on Farman by François Peyrey, in ‘La conquête du Grand Prix de l’Aviation’, MAELB, dossier FARMAN, Henry, Perso F3 (probably originally in La Vie au Grand Air, date unknown)
‘Son of one of our most esteemed colleagues, the Paris correspondent of the Standard, Henry Farman is English. Cold, and thus not at all expansive, he hides, as if from modesty, his disappointments and his joys. He seems perfectly happy, however, with his great success. Shall I say what his preferred occupation is outside sport? It is simple and healthy: the cultivation of fruit trees.’
………………………………………...
And – from ‘Souvenir’, by Hélène Dutrieu, in MAELB, dossier FARMAN, Henry, Perso F3 [no publication data, though probably 1958]
‘I was fifteen when I first knew him. The Farman brothers were training on their tandem, and when I arrived at the track – a kid, with my plait down my back – Henry, who was always kind, shouted to me “Come on! Come on! Dutrieu, come along. Get behind us, we’ll lead!” And I followed, pedaling as hard as I could.
Life separated us. I reencountered Henry Farman in 1907. He lived close to Monmartre, in an attic that he had decorated delightfully as an artist’s studio. I introduced him to the director of “Gil Blas”, Pierre Mortier; they liked each other and quickly became friends. How many times we climbed that little stairway to pass the evening and talk of painting.’

From L’Aérophile, November 1907 (15:11) ‘Portraits d’aviateurs contemporains’
[Most of what is here about Farman is shown elsewhere in these notes. But the following description is attractive:]
‘Avaricious in words, but prodigal in acts, he charms his rare moments of leisure by completing the fine collection of works of art that he has gathered, in which is revealed his clear and certain taste as a former pupil in Fine Arts.’

1907:
1 June – Farman orders his first aircraft from the Voisin brothers.
30 September – he makes his first flight.
26 October – world records for speed, distance, and endurance at Issy, winning the Coupe Archdeacon for his 771 metre flight in 52 seconds (at 54.3 kph).
9 November – first turns.

And – Scientific American, 8 August 1908, p. 86
On 1 September 1907 Farman first flew [in his Voisin aircraft] – a ‘short flight of 20 yards’ [probably dropping to the ground again after this take off because he was holding the elevator control at full ‘up’, thus causing so much drag that the aircraft would not continue flying].

Column by Hervé Lauwick, Le Figaro, 22 July 1958, ‘Le petit carnet noir’ [apparently the name that Farman gave to the notebook recording his flights in 1907-1908; he said he made 225 attempts at flight, or flights, in his first 45 days].
[This piece is based on an interview of Farman by Lauwick, probably soon before he died, at his apartment at 55, Avenue Foch, Paris. It contains much direct quotation, presumably remembered by Lauwick or reconstructed – or possibly taped].
[Farman speaking]: [When he first became interested in flight] Archdeacon sent him to see Gabriel Voisin. Archdeacon was ‘a prodigious being’, the first to believe in aeroplanes, one of the first men to have a phone in France, and an early car driver (one trip from Paris to Lyon took 15 days, with the car weighing 150 kilos more at the end because of repairs). Archdeacon was ‘an unheard of being’ [‘un être inoui’].
‘With Voisin, we first made a glider, which disappointed us. Then aeroplanes.’ They had no excessive ambitions. ‘We wanted to slip over the trees, nothing more … Like bees.’
Farman talks of his fear of dying through flying in the early days; but only of dying before he achieved what he pursued [flight].
He speaks of early take off attempts with an excessive angle of incidence. When that was reduced, take off followed.
‘It was necessary to guess everything, learn everything, create everything. Having the steering control at one’s feet, obviously, is stupid, but I had the idea of connecting my left foot with the left cable [‘ficelle’] and the right foot with the right cable. And that worked.’
‘We concentrated the controls on a single vertical lever, and Voisin shouted out ‘A broomstick!’ The word has stayed with us. [When did the change to a control wheel happen? Probably 1 November 1907 – see the entry below.]
‘Nothing was easy for us, but everything was so simple. The first ailerons were drawn on the wings with chalk. One day, at Mourmelon, I controlled the elevator with my right hand, the fuel with the left, with my feet on the rudder, and the aileron cable between my teeth … Mais oui!’ Santos Dumont-Dumont at the time shut off fuel with his back, leaning onto a string.
[This article stresses at the start, like several other pieces, Farman’s shyness, simplicity, and goodness. Another comment is that he is always smoking. Certainly the photographs of him in 1907-1908 always show him with a cigarette in hand.]

‘Les Farman. Trois frères ont donné des ailes à la France.’
Henry Farman tried free ballooning with his brother Maurice. ‘After that we had the first gliders. We went to Berck, and there, on a sandhill, we tried to go aloft. A complete fiasco! The machine didn’t want to know anything about it. I lost interest at that point in gliding. I thought only of a motor. As soon as a motor began to turn we put it, naturally, on our bicycles; that is how the Werner motorcycle was born.’

Henry Farman was the youngest of three brothers. He was born at Boulogne-sur-Mer on 26 March 1874, and spent his childhood there. He spoke English with difficulty.
As an adolescent he showed a great ‘penchant’ for the arts, especially painting. By then the family was in Paris, where Farman studied painting with some success. Several of his paintings were shown at Salons. But he was then conquered by the ‘demon’ of sports, especially cycling, in which he ranked as ‘amongst the best practitioners on the track’. In 1892 he took part in a road race between Paris and Clermont-Ferrand. In that year he was also the French champion over 100 kilometres on a track. At the same time he formed a pair with his brother Maurice, ‘with vests in a good shade of gold’.
By around 1900 he was among the ‘virtuosi of the steering wheel’, and was chosen in 1903 to represent France in the Gordon Bennett cup, coming third. In 1902 he won the Paris-Vienna race in the category ‘voitures’.
[this article continues on p. 35 of the journal; but that is missing from the file].
…………………………………………
And --  from the Revue Aéronautique des Vieilles Racines, No. 9, January 1986
[From their understanding of how lift was produced by a wing – that the wing gave lift at a high angle of attack -- the early French pilots pulled back on their elevators on take off, holding down the tail of the aircraft. This increased drag, preventing the machines from gaining enough speed to generate the lift needed to fly. Farman was the first to realize this error and find the solution.]
On 21 October 1907 [according to Joseph Franz, who was at Issy that day] Farman was trying to take off for the fourth time. He became impatient after the aircraft, moving forward under full power, three times failed to lift. ‘We saw Farman violently move his elevator control backwards and forwards, shouting “Are you going to take off or not? Will you take off?”’ [With the elevator forward, and the aircraft horizontal on the ground] the two tailwheels rose, the machine gained speed, leaving the ground without the nose lifting, and did three seconds of horizontal flight. Farman, ‘who had recovered his phlegm, afterwards said calmly to Herbster [his mechanic], ‘I know how to fly … clean the lumières [sparking plugs?] of the engine … I’ll start again’. A few days later [26 October] Farman flew 771 metres.
[Comment by Michel Dulud, Président des Anciens d’Air France] Aerodynamically, the higher speed reached as the aircraft ran level on the ground brought the upper surface of the wing into action. [Most of a wing’s lift is generated by the top surface.] This was made even more effective later by the covering of the rear longeron [of the wing, presumably] suggested by Henri Fabre. [That is true; but it is also true that, with the tail up, the aircraft would generate less drag, and hence reach a greater speed – producing more lift.]
……………………………………………….
And -- [another account of the same event, by Farman himself]
From MAELB  Photo file FARMAN, HENRY, ‘Presses diverses. H. Farman. Perso F4 – page 15 from Inter Avia, May 1947:
(this has three photographs of the Farman 1, and a text obviously by Farman himself describing his discovery of the take off technique)
Pilots of the time [1907] were sure of only one thing – that an airplane was like a kite [needing inclination of its surfaces to the relative wind to fly]. Therefore, as soon as the airplane moved, the pilot put it into a nose up position, and held it there. The motor could not then accelerate the aircraft to flight speed.
One day Farman, having rolled on the ground for several hours without success, and exasperated by the movements of the landing gear shafts by his side, let go of the control handle [‘manche’] to press down as hard as possible on the two shafts. [The aircraft had a very substantial undercarriage; on each side of the pilot were the tops of the nearly vertical rods that had the wheels at their lower ends. Coil springs were around those rods below the pilot to absorb shocks from the ground]. It was a useless gesture but one that contributed to the development of flight, because the aircraft, free of control, rolled forward and took off to a few centimetres height. This was Farman’s first ‘aerial leap’.
There was skepticism among onlookers, however, and Farman continued to try to get off the ground with the nose-up technique.
Another chance event, however, took place several days later. ‘I was rolling along the ground, with the control lever in my belly, and the belly of aircraft, alas, close to the ground.’ A storm suddenly came up. Farman received a signal to return to the hangar as soon as possible, and from the far end of the field began to taxi as fast as possible, leaving the controls loose. Suddenly the aircraft lifted off for several metres through the cloud of dust that the storm stirred up – making in fact several leaps at a height of 80 centimetres.
Farman began to see what was happening. ‘The next day, on the board that limited the movement of the control stick, I made several marks – four in all if my memories are exact – spaced at distances that were quickly calculated.’
He started the aircraft moving with the stick at the first mark. No result. ‘Voisin, who was running alongside, started shouting impetuous imprecations to make me abandon this preposterous idea which could only, he said, cost us money and precious time without any result.’
Farman tried the stick at the second mark. Voisin, very upset, headed back to the hangar. Farman felt the aircraft was faster, lighter, and more docile. At the third mark, it took off – after a run of a few metres Farman ‘accentuated’ [pushed forward?] a very little the movement of the stick, and was airborne. ‘That day I truly felt myself born in space [naître de l’espace]… I knew how to fly.’ Voisin returned to see Farman fly at 1.5 metres height and 50 kph, and immediately understood.
………………………………………
Another account of the same story comes from Farman in 1956 (in an interview with Jean Grampaix quoted in Emile Perio, Introduction au pilotage, Editions Amphora 1966 – excerpted in Michel Garnier, ‘Henry Farman ou le décollage maîtrisé’, p. 22 in Pégase, No. 128, March 2008):
‘I succeeded after many attempts. I spent days rolling on the wheels, trying, trying, trying (in that, you know fundamentally, lies the secret of success), and I noted every day what I had tried, and I was sure that in this way, little by little, I would succeed … One morning, over a distance of one metre there were no wheels tracks: we were getting closer.
I continued my trials: nothing. Exasperated, I shook the controls. But the machine refused to take off!
But then it did! I took the controls, lifted the nose a bit – and the aircraft landed. But I had flown about thirty metres at one metre altitude. Another attempt: nothing. I had taken off, but neither Voisin, nor I, nor anyone else could say why.
My first take off happened on 7 October 1907. After that, the trials continued to be disappointing. But on the 15th of October, an interesting event took place. There was a lot of wind, and I decided to go back [to the start point]. I was rolling at speed towards the hangar, into the wind, with the controls slack … A miracle: the aircraft took off, and for 200 metres there were no wheel tracks.
I thought about it the whole night.
With those machines it was impossible to gain enough speed for take off, and even if they did leave the ground, they immediately dropped again because of increased drag – especially because it was universally thought by those who were trying to fly that once one had left the ground, the nose had to be further raised.
I resumed my trials, planning to try four positions for the elevator [‘l’équilibreur’] so as to find the best one. All these positions were for diving [i.e. nose down – in French ‘au piqué], which stupefied everyone. It was the fourth position [i.e. the most nose down] that was the good one.
That was it. After then I could take off at will.’
………………………………….
[This is truly a fascinating story. It is unclear whether, before he learned this tail-up method of take off, Farman had ever been able to get off the ground. Perhaps he had, but only for very brief hops. At all events, it made take off much easier and routine. The accidental sources of the discovery are also fascinating to read of. And it is typical of Farman that he related them, rather than simply presenting the tail up take off as a product of his thought alone. He was, in any case, the discoverer of the tail up take off for tail wheel aircraft.
Interesting, too, are his references here to a control stick or column. Photographs of the Farman 1 show a wheel as the primary control, operating the forward elevator with fore and aft movements, and the rudder by turning. The report in Le Matin for 1 November, below, states that the Voisins had just fitted a wheel to the airplane. Before then, perhaps, it had a control column?]

And --  from La Vie au Grand Air, 26 October 1907, No. 75
p. 291 François Peyrey, ‘La Semaine Aéronautique’
Henry Farman is close behind Santos-Dumont and Blériot. On 15 October he made a ‘superbe vol’ of over 200 metres (not officially observed), and should soon exceed Santos-Dumont’s 220 metre record.
Farman is now ‘absolute master’ of his elevator control. He says he flies at an average height of 6 metres. The aircraft tilts from one side to the other, but corrects itself – proof of good lateral stability. But on his last flight, Farman did not go directly into the wind. The Voisin brothers feared that he could easily be deflected by a lateral gust, and signaled him to stop.
The dimensions of Farman’s aircraft: spacing of wings, 1.5 metres; the streamlined body, 4.5 metres; tail span, 6 metres (x 2 metres chord) – the tail cell is ‘provided with a special stabilizing empennage’ [not explained]; propeller, 2.1 metres diameter and 1.1 metres pitch. The lifting area is 50 square metres, and total weight 500 kilos.
On 30 September Farman made flights of 30-80 metres. He is a ‘new and excellent recruit’ to aviation. [This date is suspect.]

France Aviation, No. 46, September 1958
pp. 1 & 3.  Henry [sic] Beaubois, ‘Souvenirs sur Henry Farman’
p. 1. In 1907 Farman’s devoted mechanics were Maurice Herbster and Charles Kieffer, known as ‘Charlot’.
Beaubois emphasizes the trickiness of the Levavasseur Antoinette motor, especially the ‘shakers’ [‘trembleurs’] providing ignition[‘allumage’] at the ‘mouches’  -- ‘small connectors [‘raccords’] pierced with a very small hole [‘trou infime’] by which the cylinders received fuel’.
p.3. Re problems of turning. Farman told the writer that he had to face the opposition of theoreticians, who held that an aeroplane, ‘with the danger of losing its point of support in the air and of slipping [in and down] on the wing without recourse, would never be able to attempt a change in direction’. Farman boosted the effect of the rudder by moving on his seat [leaning into turns?]. The rudder here is described as being of ‘happily vast dimensions’ [which it was not]. In this way he began making S turns.
[Farman’s practical experimentation and demonstrations of turning here proved the theoreticians wrong. But their view that turns were impossible is part of the prevailing French belief, until late 1908, that an aircraft had to be kept straight and level as far as possible. By turning with wings level, as far as they could, Farman and others certainly produced skidding, and the tendency of the inner wing on the turn to slide inwards and downwards.]

From here, excerpts mostly from Le Matin

5 May 1907
p. 5   MM. Farman [in the plural – the previous paragraph refers to Maurice and Dick Farman recently flying a balloon from the parc of the AéroClub de France, presumably at St. Cloud] are now having an aeroplane built, of 30 square metre surface and a total weight of 250 kilos. It will have a 20 hp motor. The contract states that they will not accept the aircraft until it can make of circuit of 1,500 metres without touching the ground. The builders are not specified. [This may be the first mention of any Farmans in Le Matin – although earlier references are possibly in paragraphs about ballooning. Maurice Farman did not in fact do any flying of aeroplanes at this point, and Dick Farman was even further from the aeroplane story. There is a possibility here of confusion of these two with their brother Henry.]
……………………………………………….
15 August 1907
p. 4   A new aéroplane will be tested soon – Farman’s. Construction began by the Voisin brothers last month, and it is now finished. [A description of the machine follows. It is odd that it is not compared to Delagrange’s aircraft.]
The aircraft has a wing [‘cellule centrale’] of two planes (10.2 span by 2 metres chord), set 1.5 metres apart. The wings are connected aft by a beam 4.5 metres long, at the rear of which is the rear cell. This has two surfaces of 6 x 2 metres, and special tail surfaces [‘empennage’] assuring perfect stability. Inside the rear cell is a vertical rudder [‘gouverneur’]. In the central cell [the biplane wing] is a reinforced beam carrying the motor [‘groupe moto-propulseur’]. At the front is an elevator [‘gouverneur de profondeur ou équilibreur’].
The frame is made of ash wood, and is covered with cloth, with a special varnish. The whole stands on a framework [‘châssis’] with orientable wheels, so that landing is possible in a cross wind.  The total wing surface is 52 square meters; the span, 10.2 metres; the total length, 10 metres; the motor, 50 hp; the propeller, 2.1 metres long and 1.1 metres in pitch; total weight, 500 kilograms; predicted speed, 50 kph.
The first trials will be made next week at Issy, where a very large hangar is being made to house the machine.
[The description of the tail given here is rather odd. What exactly the ‘empennage’ is, is rather puzzling. The word usually refers to all tail surfaces of an aircraft. Here, possibly, it applies only to the two fixed vertical surfaces at each end of the horizontal planes. This is the first description of Farman’s aircraft.

16 October 1907
p. 1  [front page article with photograph]  ‘Victoire de l’aviation. 280 mètres en aéroplane. M. Henry Farman bat le record que détenait Santos-Dumont depuis le 12 novembre.’
‘Aeronautical science has just made a new ‘flight’ on the road to progress.’  Farman’s 280 metres flight took place yesterday afternoon at Issy. The ground was wet from recent rain. It seemed more of a marsh than a testing ground. Farman did not hesitate, but between two showers took his machine near to the Porte d’Issy. After a take off roll of some 10 metres he rose from the ground gracefully and stably. Using the front plane [elevator] Farman went to some 10 metres of altitude, and then closer to the ground, and continued to fly until, responding to continued appeals from Gustave  Voisin, he landed in thick mud. A distance of 280 metres was measured. The aircraft is of the Chanute type – i.e. it has ‘cellules’ [biplane wing and tail]. It had been slightly modified after a first trial. The angle of incidence of the rear cell had been reduced, and the ‘equilibreur biplan’ [biplane elevator in the nose] replaced by a single plane. This structure was advanced [placed further forward, presumably} on the fuselage by 10 centimetres, and raised 30 centimetres, so that the whole of the bearing surface would act effectively.
This is a great success for Farman, and for the Voisin brothers and Colliex, to whom [all three, presumably] Farman had left all initiative about construction. [So the reduction of the biplane elevator to a single plane was the Voisins’ decision?].
[A photograph of the aircraft here shows the monoplane elevator in the nose, but still the wide biplane tail – which was not reduced in span until early December 1907. Over the engine is a water tank.]
[There is no reference here to other trials by Farman after 2 October.]

On the sixth flight the aircraft made a wide curve and Farman did not hesitate to fly over spectators. The flight were seen by Archdeacon, Santos-Dumont, Surcouf, Delagrange, Max Richard, Lhermit [sic].

p. 1   ‘770 mètres en aéroplane. M. Henry Farman bat officiellement tous les records’
Recently Farman had flown 280 metres before friends and spectators. Yesterday morning and afternoon he started with a flight of 363 metres, but without official witnesses. In the afternoon, with Archdeacon, Kapferer and Tatin present (all members of the Commission d’Aviation) he flew 403 metres; then, towards sunset, he flew the whole length of the field, stopped only by the fence. He covered 770 metres. It is clear that Farman will soon pursue the 50,000 francs prize for a 1 kilometre circuit. Now he has the two prizes of the AéroClub de France for 300 and 500 metres: a total of 1,500 francs. Farman was fêted last night at the AéroClub de France. The bet between Archdeacon/Santos-Dumont and de Dion/Charron that a 500 metres flight would occur before 1 January 1908 has therefore been lost by de Dion and Charron.
…………………………….
L’Aérophile, October 1907
p. 286-289   ‘Henri Farman vole près d’un kilomètre’
[This article confirms the above information from Le Matin, adding detail about the flights, but little of substance. It summarizes Farman’s flights since 15 October 1907, emphasizing how easily Farman controls the aircraft and how gently it lands. Spectators on the field prevented Farman from flying further on 26 October; but then they were excluded and conditions for flight improved. There is emphasis that the 771 metre flight on 26 October could have been much longer, but Farman ran out of space on the Issy field, stopping only 10 metres from the surrounding wall. The total distance flown by Farman on 26 October was 2,597 metres. Farman has won prizes for 300 and 500 metres from the Aviation-Club de France, worth 1,500 francs. ]
‘It is certainly difficult to render too much homage to the courage, sang-froid, and skill of Henry Farman, a man already legendary for all cyclists and drivers.. We must also bow before the untiring and intelligent stubbornness with which he has methodically pursued his apprenticeship as an aviator.’
But Farman would not like to dissociate his name from those of Gabriel and Charles Voisin, who studied and built his machine in accord with their aviators’ ideas – already experienced, practiced and  universally well reputed. Levavasseur, the producer of the Antoinette motor, must also be included in this record.
Farman will now attempt to turn. Already, on 28 October, he managed a quarter circle. It is now clear that he could make a large radius turn if he had enough space, and thus take the Deutsch-Archdeacon prize.
The Farman aircraft has been modified. The forward elevator has been changed from biplane to monoplane. The upper surface of the tail has been made into a lifting surface [by giving it forward-aft curve].
[Farman’s tail-up take off technique is also described here]. He does not touch the elevator until the machine has taken off, when he can easily judge the small movements needed to keep the aircraft at a good angle of attack, and to fly indefinitely (as long as fuel lasts). [Not so, in fact: the cooling system of the engine at this point involved the cooling water being boiled off as steam; after a few minutes, the engine had no more coolant fluid.]

29 October 1907, p. 5.  
Henry Farman ‘s’entrame/s’éntrâine en virage’. [Hard to read; ‘s’entrâine’ certainly makes more sense]. For some weeks past few people have come to Issy-les-Moulineaux; but yesterday it seemed to be a ‘garage d’automobiles’.
In the afternoon, Farman sketched out his first planned turn (‘a esquissé … son premier virage raisonné’). A strong cross wind carried the aircraft sideways. It was low. Farman could not straighten it, and one wheel ran on the ground, and was a little buckled (‘voilée’). This was the first damage to the aircraft.
…………………………………………………
L’Aérophile, November 1907, p. 302. ‘Premiers virages de l’Aéroplane Henri Farman’
[unusual spelling of Henri with final ‘I’ – usually ‘y’]
Farman, well known for his cycling and automobile past, has now shown himself to be a ‘marvellous practician of mechanical flight’.
With the Voisin aircraft that Farman has, the role of the technician is finished, and the role of the ‘sportsman-aviator’ begins. This latter role is of prime importance at the current stage of development of mechanical flight. Farman has tackled this need. He is dealing with the problems of flight as they arise: take off, sustained flight, stability in height, landing. Today he managed turning, the last task of his difficult apprenticeship.
Farman is now complete master of his machine. On 1 November he performed two trials at Issy. In the first he took off easily, but did not turn. In the second the  aircraft began a turn, but touched the ground, suffering slight damage. This repaired, on 2 November Farman carried out taxiing trials at Issy, using the rudder to change direction. On 5 November there were numerous successful flights of 300-400 metres, with the beginnings of turns.
On 9 November Farman started with an 800 metre flight, making a ¾ turn. After this came a flight with two turns in S form. In the third flight achieved a complete turn in the air, following a U course. The turn was sharper than expected, but was done without loss of height, at roughly 3 metres altitude. The aircraft was hardly banked into the turn. The wings were level once the turn was finished, and the return flight almost parallel to the outward leg. The flight lasted 1 minute 14 seconds (measured by Archdeacon, and a record flight for a powered machine). The speed was 14 metres/second, and the distance flown 1.036 km. Farman is now ready to take the Deutsch-Archdeacon prize (and would have won it with the flight described, except that he did not close the loop).

A false announcement was made that Farman’s trials would continue yesterday. The result [at Issy] was an elegant crowd on the swampy airfield (‘public élégant sur l’aérodrome marécageux’).
Farman will do trials today. The chassis of the airplane has been remounted (‘remonté’). The Voisin brothers have placed in front of the pilot’s seat a wheel operating all controls of the machine (‘un volant sur lequel aboutiront toutes les commandes de l’appareil’). [These would be the rudder in the tail, and the forward elevator.]

2 November 1907, p.6.
A substantial police presence was needed yesterday at Issy to allow Farman to continue his trials. The ‘public élégant’ included Léon Barbon [Barthou?], Besançon, Delagrange, Archdeacon, Blériot, the Voisin brothers, Tissandier, Henry Kapferer, Commandant Bouttieaux, Captain Voyer, Santos-Dumont, Captain Ferber, Garnier, de La Vaulx, Tatin, Gastambide, Chanvière, and others. There was a crowd of a thousand on the fortifications and the wall around the field (in contrast to the twenty or so [‘vingtaine’] spectators of early flights).
Farman’s first flight was of about 400 metres from a corner of the field. On the second flight, owing to a bad control movement, the machine tilted to the right. Two uprights of the interior layout of the wing cell and of the elevator were broken [‘deux montants du plan intérieur de la cellule et de l’équilibreur se brisèrent’].
The crowd burst through the cordon of police onto the field to see the ‘monstre’ up close. The densest pack came through the Porte d’Issy. Immediate action was taken. Some drivers directed [outwards] as best they could the five or six thousand people immobilized on the field. Farman made two more flights to display the aircraft. Then it was taken back to the hangar. [‘On répara immédiatement; quelque chauffeurs canalisèrent tant bien que mal les cinq à six mille personnes immobilisées dans l’aérodrome. Farman fit encore deux vols mécaniques pour la vulgarisation de l’aéroplane’]
[These flights were presumably made before the aircraft was damaged. The order of events is not clear from the account.]

A full picture of Farman’s machine in flight – supposedly the flight of 26 October 1907 at Issy with which he took the distance record of 771 metres, after making several flights of more than 300 metres. The flight was at 6 metres altitude, without undulations, straight, and with a very smooth landing. It lasted 52 seconds. [The aircraft has a monoplane forward elevator, but still the wide tail.]

Farman made a remarkable series of 450-650 metre flights yesterday, with a strong cross wind.

8 November 1907, p. 5.
Farman made a series of very fine flights yesterday. He was limited only by the size of the field at Issy (950-1,000 metres long, but 200 metres are needed for take off and landing; so 800 metres is the longest straight line flight possible). The ‘sympathique aviateur’ says he will soon be able to turn, but he will go to Beauce or the camps de Châlons, where there are ‘vastes distances’. [He did not.]
……………………………………………………..
9 November 1907, p.5.
Yesterday, late in the day, Farman turned at Issy – an event [‘évènement’] in aviation.  He said he could have completed a circle if the belt on the water pump had not come off. The aircraft did a half-circle at 2-3 metres height and of some 300 metres diameter.
 [This was indeed a major event in the development of flight in France. It was probably the first intentional 180 degree turn. Easing this machine round in a turn was difficult. With only rudder to make the turn, skidding would have ensued, with increased drag. The resulting loss of speed meant loss of lift, and a tendency for the machine to lose height. Keeping enough speed to maintain height must have been a very delicate matter of control.]

10 November 1907.[Heading] Un virage triomphant. Un kilomètre en aéroplane. Henry Farman a fixé le Record de l’Aviation.’ [A photograph shows the aircraft allegedly during this flight. It still has the wide tail, which was not replaced by a tail of lesser span until the beginning  of December 1907.]
Farman flew one kilometer, making two turns. Aviation now looks to become a new means of locomotion. Farman has now fulfilled the conditions of the Deutsch-Archdeacon prize (of 50,000 francs). He landed close his departure point. The flight lasted 74 seconds, at 13.5 metres per second, giving 999 metres flown. Farman was applauded by Archdeacon, the Voisin brothers,  Henry and Marcel Kapferer, Blériot, de Fayette, Humphrey, Buisson, Risse, and others.
Farman took off again and flew a long S turn. There is nothing finer than to see ‘the immense white bird which stood out against a framework shadowed by night and fog, and which, slipping through the air, sometimes to the right, sometimes to the left, levelled itself, rose, and fell according to the will of the pilot.’
Farman will try for the official prize [the Deutsch-Archdeacon prize] next week.

They were interrupted by malfunction of the water circulating system; but will restart in a few days.

Farman was to attempt today a 1 kilometer closed circuit for the Deutsch-Archdeacon prize. But the detachment [it was ‘déclavetée’ – unriveted?] of one blade of his propeller prevented this try. Repair will happen today.

15 November 1907, La Revue de l’Aviation, 15 November 1907 (No. 12, 2e année)
p. 3 ‘Un Interview de M. Archdeacon’
Archdeacon says that the only thing that has prevented Farman from taking the Deutsch-Archdeacon prize is the fact that, once in the air, he cannot estimate the angle at which he is flying his machine. His take off angle allows for maximum speed [apparently, then, this opinion is being give after Farman had learned to keep the machine’s tail up and level during take off]; but then he cannot judge the angle of the machine relative to the flight line – the angle increases and the aircraft drops. Its speed, which should be 5-55 kph, declines to 20 kph. Slowing of the motor does not seem to be the cause of this loss of speed. It seems that the reason is that Farman, occupied with much else in the air, ‘can scarcely survey his line of flight continuously’. What is needed is an instrument that would give a reading of the machine’s pitch attitude. It would have to be very quick. Such instruments exist for cars, but they are too slow to react. A good airborne instrument would enable pilots to fly at a pitch angle producing the least drag.
[Archdeacon continues:]  A new prize – perhaps of 10,000 francs – could stimulate the development of such an instrument.
Farman, when asked about the above, said:
He has thought along the same lines as Archdeacon. But he cannot say that such an instrument would remove all the difficulties of remaining for some time in the air – though it would help enormously. For the moment he thinks that once he can make his motor function regularly, he will be able to stay in the air as long as he wishes, relying on instinct and practice to keep to a good line of flight. Until now he has judged the pitching movements of the aircraft by looking at its forward end in relation to distant objects. That is a crude method, but will have to suffice until an instrument of the sort proposed by Archdeacon appears.
Personally, Farman thinks that all that is needed now to win the [Deutsch-Archdeacon] prize and achieve more remarkable flying is to have a steady [‘regulier’] motor and much practice. ‘Only practice, nothing else, allows mastery of an airplane.’
[Commentary of the magazine:] 
 Archdeacon’s point that high into-wind angles cause loss of speed is true. This view is supported by the fact that when Farman started flying some months ago he was never able to fly more than 200 metres, even with his motor in excellent condition. He took off at too high an angle, resulting in rapid loss of speed and descent to the ground. It was not until he took off at such a low angle that it was hard to say at what point the wheels left the ground, that long flights became possible.
[Farman was right. It is easy to maintain a correct pitch angle by looking ahead. No instrument is needed so long as there is visibility. His stress on practice is worth noting. Unlike most other French pilots in 1907-8 he flew often, and suffered only one accident. He is possibly realizing that controlling an aircraft in three dimensions is a new human experience, different from controlling machines on the ground or on water. Finally, his dissatisfaction with the Antoinette engine is beginning to emerge. It becomes greater in 1908.]
………………………………………………………….
18 November 1907, p.4.
Farman plans to attempt the Deutsch-Archdeacon prize tomorrow, between 9 a.m. and 4.30 p,m.
……………………………………………………..
19 November 1907, p.5.
Farman did not win the Deutsch-Archdeacon prize today because of a repair needed to the propeller shaft.
The public had scarcely left the field when the dirigible Ville de Paris arrived at Issy, at midday, and landed. Henry Kapferer and ??  Paulhan, dressed like eskimos, and M. Baudry emerged from the nacelle. ‘Le Tout-Issy et le Tout-les-Moulineaux vinrent examiner de près le vaisseau aérien.’
At 2.30 Farman was ready. ‘Policemen, agents [security men?], mounted soldiers, civilian devotees wearing armbands, dignified the chosen and elegant crowd. All the countries of the world were represented; the English Aeroclub had sent its president, the German Aeroclub had delegated one of its members. A hundred or so cars were parked hither and yon. Although he was modest and shy, Henry Farman did not lose his self-possession in front of this select audience. He had, moreover, much to do: checking balance, handling the steering,, regulating the motor, seeing to good carburation are not child’s play. Carburation alone did not favour the aviator. Having changed the pump which keeps the fuel tank under pressure, M. Farman realized that he must modify the control of fuel admission to the engine.
[ ‘Des gendarmes, des agents, des cavaliers, de devoués civils portant des brassards endignèrent la foule élégante et choisie. Tous les pays du monde étaient représentés: L’Aéroclub de l’Angleterre avait envoyé son président, l’Aéroclub d’Allemagne avait délegué un de ces membres. Une centaine d’autos étaient garées un peu partout. Bien que modeste et timide, Henry Farman ne perdit pas son sang-froid devant ce public select. Il avait d’ailleurs beaucoup à faire: surveiller l’équilibre, commander le gouvernail, régler le moteur, avoir la bonne carburation ne sont pas jeux d’enfant. La carburation seule ne favorisa pas l’aviateur. Ayant changé la pompe avec laquelle il tient le reservoir d’essence sous pression, M. Farman se rendit compte qu’il devait modifier le réglage d’admission d’essence dans le moteur.’]
Then, in six trials of 400-600 metres each, the aircraft touched down at the moment of turning . For the final trial, Farman reset carburation in a happy way, and the aircraft covered some 1,500 metres in a circle [‘en circuit’] – but grazing [‘effleurant’] the ground twice in a space of 6 to 8 metres.
Meanwhile the Ville de Paris left Issy, after flying over the field.
Farman’s efforts show he is the strongest contender for the prize.
Santo Dumont will do trials this morning at Bagatelle, and may come to Issy if he decides to try for the prize.
………………………………………………………….
20 November 1907, p.5.
Farman did not fly yesterday at Issy. He worked on mechanical parts of his aircraft. He changed the pitch of the propeller. He will try for the Deutsch-Archdeacon prize today between 10 a.m. and 4 p.m.
……………………………………………………….
21 November 1907, p.4.
Farman tried for the Deutsch-Archdeacon prize yesterday, without success. He had problems of carburation, and flew only in straight lines for 400 to 600 metres.
……………………………………………………….
22 November 1907, p.5.
Though intending to fly for the Deutsch-Archdeacon prize yesterday, Farman only practiced, though not until after sunset. The aircraft behaved well in straight line flight, despite a strong and variable wind.
To get constant fuel pressure, Farman has placed the fuel tank above the wing [gravity feed instead of use of a pump?], and proposes to raise it still further. This will, he hopes, prevent fall in fuel pressure during turns, which he hopes to manage without loss of height [‘abattée’].
[Generally Farman now is tweaking the engine and propeller to achieve more power, especially for turning.]
………………………………………………………
23 November 1907, p.5.
Farman (‘le brillant aviateur’) made flights yesterday in his No. 1 machine, with what purpose is not clear, though his recent efforts seem to have led to a decline in progress. Farman has been concentrating lately on mechanical matters, thinking that the motor shaft may have suffered with the breakage [‘rupture’] of the propeller. He will, nonetheless, try for the Deutsch-Archdeacon prize at Issy today, from 10 a.m. on.
……………………………………………………….
24 November 1907, p. 5.
Yesterday Farman made a circling flight of 600 metres. Flying in the afternoon was prevented by a storm [‘tempête’]. He has restored the end of the motor shaft, which he thinks was slightly bent [ ‘faussée’].
……………………………………………………….
29 November 1907, p.4.
Farman will try again today for the Deutsch-Archdeacon prize, despite the poor weather – from 9.30 a.m. until sunset.
………………………………………………………
30 November 1907, p.4.
Farman got his aircraft out yesterday, but the field was very wet. Mud and water on the ground prevented him from gaining enough speed to fly.
……………………………………………………..
3 December 1907, p.5.
Farman took his aircraft out yesterday at nightfall. The fuselage frame has been lightened by 7 kilos. But mud and water on the ground prevented flying. The weather may improve today.
…………………………………………………….
4 December 1907, p.5.
Farman has modified the tail surfaces [‘la cellule arrière’] of his aircraft, reducing the span. The new tail will provide the same lift but resist the air less. The aircraft has had reductions of 15 kilos in weight and 13 kilos in drag [‘résistance’]. Altogether Farman has gained 35 kilos [i.e. reduced weight by 35 kilos], and 5 hp in thrust (because of reduced drag). [The span of the tail was reduced from 5 to 2.7 metres. In addition the lower surface was now given curve, whereas it had been flat before. The intent was to increase lift from the tail. This from Michel Garnier, ‘Henry Farman ou le décollage maîtrisé’, in Pégase, No 128, March 2008, p. 29.]
……………………………………………………..
7 December 1907, p.4.
Yesterday Farman tried his machine for the first time with a smaller tail. The tail rose too quickly, causing a forward shift in weight, and a risk of pitching down onto its nose. Some tubes in the frame have been replaced by others that are stronger. But these fitted together badly [‘s’embottèrent mal’], and while the aircraft was being pushed towards the departure point, rods gave way [‘les tiges cédèrent’] and the front of the aircraft sagged. But the damaged was repaired in five hours.
……………………………………………………..
[there follow more than ten days here without reports of flying – possibly because of bad weather?]
……………………………………………………...
27 December 1907, p.5.
Farman began his flying activities again last week, but is not getting the ‘brilliant results’ of last month. The aircraft is flying and is stable, but progress seems blocked for mechanical reasons. Farman said yesterday that the engine was giving only 1,080 revolutions, rather than 1,200. According to the builders’ calculations, the aircraft can fly with 45-50 hp, but, according to Farman, only 38-40 hp are now available.
……………………………………………………….
1 January 1908, p.5.
Farman will continue trials tomorrow. Yesterday he practiced turns, and will spend 1 January covering the wooden longerons of his cellular apparatus [‘à entoiler les longerons de bois de son appareil cellulaire’]. He is not wasting time. He [‘le recordman du monde’] plans to modify the rear cell of the aircraft. [Whether he did modify the tail of the machine is unclear. But the covering with cloth of the upward projecting rear spars on the wing – the ‘longerons de bois’ mentioned here – was clearly done before his prize winning flight on 13 January. The reduction in drag was probably considerable.]
……………………………………………………….
6 January 1908, p.5.
Farman, having flown a cellular (i.e. biplane) aircraft with perfect stability, now intends to use a lower drag monoplane, which will be faster but more dangerous. The Voisin brothers will build this for him. He wants four pairs of wings: 1 [far] forward as an elevator [‘équilibreur’], 2 near the nose, and 1 in tail. It is reported that a new, light motor will power this aircraft, though this is still several months off.
[This aircraft was never finished. There are photographs of it in the Voisins’ factory, but apparently it was abandoned.]
………………………………………………………
7 January 1908, p.5.
Farman resumed flying today, making several flights, interrupted by a breakdown of ignition [‘allumage’].
……………………………………………………..
12 January 1908, p.6.
Farman flew yesterday at Issy, making eight trials despite the cold and frozen ground. He succeeded twice in completing a 180 degree turn, returning to his departure point, and staying airborne for 1 minute 45 secs (thus flying about 1,500 metres). Weather permitting, he will attempt the Deutsch-Archdeacon prize tomorrow.
……………………………………………………..
25 January 1908
La Vie au Grand Air, No. 488. François Peyrey, ‘La Conquête du Grand Prix d’Aviation’

pp.52-3.  During the turn on the prize winning flight, the aircraft dropped a little (though very slightly banked), and then regained height immediately. The radius of the turn was 200 metres.
Before the flight, the ‘projections [‘aspérités] presenting damaging resistance had been covered with cloth and masked’. With resistance [i.e. drag] thus reduced, the builders estimate that the equivalent of 12 hp had been gained. 

[This is very likely a reference to Farman’s covering with cloth the previously exposed rear spar on the upper and lower wings of the aircraft. It stuck up from the top surface perhaps two inches, and perhaps two feet forward of the trailing edge. The decrease in drag on the upper surface of the wing after the spar was covered would have been considerable. This change seems to have been made on 1 January -- see the entry for that date, above.]
………………………………………………………
See also for the covering of the spar Revue Aéronautique des Vieilles Racines, No. 9, January 1986.

p.9. Michel Dulud wrote to Henri Fabre (then 97 years old) asking him about Pierre Lissarague’s report that Fabre had recommended to Farman, before the 1 kilometre prize flight, that he should cover the upper surface of the wings of the aircraft. Fabre replied that he spoke to Farman about the rear spar [‘longeron arrière’] before the flight. Everyone knew that Blériot made wings on which the upper surface was covered with paper; and Fabre knew that the Wrights covered their wings top and bottom with cloth. It took all of Farman’s energy to do the ‘enormous work’ of sewing on both the upper and lower wings. The total length of spar [‘longeron’] was 20 metres. The strip of cloth being applied had to be sewn on both its forward and rear edges – a total of 40 metres of sewing. A female worker was required to pull and prick the cloth. The work on the upper wing required a scaffold. 

[Photographs of the aircraft in the fall of 1907 show no sign of this strip of cloth towards the rear of the wing. By contrast, photos taken after the 13 January flight clearly show a dark strip running the whole span of the wing; there is a double thickness of cloth there. And the photograph of the aircraft about to cross the finishing line on the prize winning flight appears to show that same strip, though it is not wholly clear. But the note above shows that Farman added the strips over the spar on 1 January.]

………………………………………………………
ON THE NEXT DAY, 13 JANUARY 1908, FARMAN DID INDEED MAKE THE 1 KILOMETRE FLIGHT, INCLUDING A 180 DEGREE TURN BACK TO HIS STARTING POINT.
(This was a repetition, in front the required official witnesses, of what Farman had done on 10 November 1907.)
………………………………
Gabriel Voisin left a description of this flight (quoted in Michel Garner, ‘Henry Farman ou le décollage maîtrisé’, in Pégase No. 128, March 2008, p. 27):
‘About 7 a.m. my brother set out the flags. The weather was calm, and the sky clear. The airplane was kept in a hangar besides the exercise field. On trial days we placed a bridge made of planks over the wall that closed off the field, and we crossed the wall to get to the field … We pushed the machine to the end of the field, near the Pont de Sèvres. Present were the commissioners [of the AéroClub]; among the people from the AéroClub was Blériot. The two departure posts were placed on the side of the field that looks towards Paris, because I had predicted that day a light westerly wind that would favour the departure. The flag at the other end of the field was barely visible because of the morning mist. Farman climbed into the fuselage, the commissioners took their places close to the departure posts, and I myself started the engine. The take off was extremely quick. About twenty metres after lifting off the machine was at the height of the posts. The tight turn seemed to me too steep, but the return was completely reassuring. The aircraft, guided by its pilot with consummate skill, crossed the finish line at about ten metres height, and then landed close to me.
The time of this flight was very short: 1 minute 28 seconds; but the cooling water had had time to evaporate, and I can still see the little cloud of steam which rose for a few seconds after the aircraft stopped.’
………………………………..
Farman wrote a description of the aircraft flown on 13 January for the Académie des Sciences in Paris. It was read to a meeting of the Academy by M Henri Deslandres on 20 January 1908:
The apparatus is composed of a principal cell [biplane wing] of 10 metres span by 2 metres chord, formed by two superimposed planes measuring 40 square metres [in area]. It has a smaller cell in the tail, of 3 metres span by 2 metres chord, with an area of 12 square metres. Placed forward is an elevator [‘équilibreur’], consisting of a single plane, hinged to allow variation of its angle, and by this movement make the machine rise or fall. The motor is at the centre of the main cell, in a sort of streamlined nacelle in which the pilot has his place. In the tail is the hinged rudder used to make the airplane turn right or left.
The aircraft is carried on a frame [‘châssis’] of steel tube, fitted with two steerable [‘orientables’] pneumatic wheels … I chose the cellular or biplane form for my aircraft because I consider this to be the most studied form, and the one that gives the best stability; I have chosen it also because of its simple construction and its solidity. I believe that my success is due, above all, not to the general form of the aircraft, but to the numerous methodical trials and successive modifications inspired by experience.
The Voisin brothers, who built my aircraft, have certainly played a large part in my success, for it is thanks to their competence in the matter [of flight], to their activity, and to their intelligence, that I have arrived at the result …’
[This is from p.27 of Michel Garnier, ‘Henry Farman ou le décollage maîtrisé’, in Pégase, No. 128, March 2008, pp. 22-31.]
[On p. 29 of the same issue of Pégase, Garnier adds to Farman’s description]:
Construction is of wood, except for the châssis [undercarriage frame], which is made of steel tube. The covering of the flying surfaces [wings and tail] is of rubberized cotton, and of single thickness because lightness is the aim; the aerodynamic advantage of thickness in the wing has not yet been realized. The wing ribs are in sewn gussets.
Total length is 10.50 metres.
Total weight is 530 kilos, giving a wing loading of 10 kilos per square metre – which today is ridiculously low, but at the time normal, or even high.
The motor is an Antoinette of 50 hp, at 1,400 rpm; though it was used at only 1,050 rpm, driving directly a two-bladed steel propeller of 2.30 metres diameter designed and made by Gabriel Voisin.
Flight controls: the pilot has in front of him a wheel that he can push or pull, controlling the forward elevator, and thus producing climb or dive. He can also turn it to right or left, moving the [vertical] rudder [in the tail]. There is no engine speed control. The engine runs at full throttle; the pilot cuts ignition just before landing.
…………………………………………
…………………………………………
What particularly draws attention in the flights leading up to success on 13 January 1908 are the modifications to, and lightening of, the aircraft.  The rear spar of the wing, which previously projected upwards into the airflow, was covered with a strip of cloth (as explained above). The span of the tail was reduced, with savings in weight and drag. Problems with irregular fuel feed, or pressure, were apparently solved by putting the fuel tank above the upper wing, and using gravity to provide a constant and even flow of fuel to the motor. The recurring problem of small amounts of damage – wheels bending, parts of the fuselage not fitting together well – is clear. The engine appears to lose power, for reasons not explained but perhaps having to do with fuel feed. The resolution of that problem is not explained in Le Matin; perhaps the placing of the fuel tank above the wing was enough. The problems of muddy ground are clear, making it hard for the aircraft to move easily. It is notable that the ground was frozen when Farman made his prize-winning flight on 13 January 1908.

Farman’s growing eminence as an aviator is also reflected in the changing descriptions applied to him by Le Matin, from ‘le sympathique aviateur’ on 8 November, to ‘le brillant aviateur’ towards the end of that month, to ‘le recordman du monde’ on 1 January 1908.  It was in early November that Farman learned how to turn the aircraft, a very remarkable accomplishment considering that it had only a quite small rudder to produce the turn. Le Matin’s reports do not emphasize enough the importance of this development, which Farman was the first to achieve. French aircraft had been designed to fly straight; he had a struggle, fighting his machine’s natural directional stability, to persuade it not to do so. It tended to lose height while turning; hence Farman’s efforts to lighten it. He succeeded finally in making turns, with difficulty and practice; although it was not until a year later, after Wilbur Wright had demonstrated in France the efficacy of wing warping for turning, that the French adopted either warping or ailerons as the means of producing bank, and resulting turn. Clearly the Voisin-Farman 1 aircraft flown by Farman had only just enough power, if the engine were working at full power, to achieve turning flight. It was a heavy and draggy machine. Early in 1909 Farman designed and built another aircraft on the same pattern, but much lighter. He did well in that machine in 1909.
