In his book My Airships the distinguished aviator A. Santos-Dumont tells this story of the ambition of his youth and its realization in later days: I cannot say at what age I made my first kites, but I remember how my comrades used to tease me at our game of "pigeon flies." All the children gather round a table and the leader calls out "Pigeon Flies! Hen flies! Crow flies! Bee flies!" and so on; and at each call we were supposed to raise our fingers. Sometimes, however, he would call out "Dog flies! Fox flies!" or some other like impossibility to catch us. If any one raised a finger then he was made to pay a forfeit. Now my playmates never failed to wink and smile mockingly at me when one of them called "Man flies!" for at the word I would always raise my finger very high, as a sign of absolute conviction, and I refused with energy to pay the forfeit. The more they laughed at me the happier I was, hoping that some day the laugh would be on my side. Among the thousands of letters which I received after winning the Deutsch prize (a prize offered in 1901 for sailing around the Eiffel Tower) there was one that gave me peculiar pleasure. I quote from it as a matter of curiosity: "Do you remember, my dear Alberto, when we played together 'Pigeon Flies!'? It came back to me suddenly when the news of your success reached Rio. 'Man flies!' "They play the old game now more than ever at home; but the name has been changed, and the rules modified since October 19, 1901. They call it now 'Man flies!' and he who does not raise his finger at the word pays the forfeit." The story of Santos-Dumont affords a curious instance of a boy being obsessed by an idea which as a man he carried to its successful fruition. It offers also evidence of the service that may accrue to society from the devotion of a dilettante to what people may call a "fad," but what is in fact the germ of a great idea needing only an enthusiast with enthusiasm, brains, and money for its development. Because the efforts of Santos-Dumont always smacked of the amateur he has been denied his real place in the history of aeronautics, which is that of a fearless innovator, and a devoted worker in the cause. Born on one of those great coffee plantations of Brazil, where all is done by machinery that possibly can be, Santos-Dumont early developed a passion for mechanics. In childhood he made toy airplanes. He confesses that his favourite author was Jules Verne, that literary idol of boyhood, who while writing books as wildly imaginative as any dime tale of redskins, or nickel novel of the doings of "Nick Carter" had none the less the spirit of prophecy that led him to forecast the submarine, the automobile, and the navigation of the air. At fifteen Santos-Dumont saw his first balloon and marked the day with red. © U. & U. A British Kite Balloon. I too desired to go ballooning [he writes].

From dreaming, the boy's ambitions rapidly developed into actions. Good South Americans, whatever the practice of their northern neighbours, do not wait to die before going to Paris. At the age of eighteen the youth found himself in the capital of the world. To his amazement he found that the science of aeronautics, such as it was, had stopped with Giffard's work in 1852. No dirigible was to be heard of in all Paris. The antiquated gas ball was the only way to approach the upper air. When the boy tried to arrange for an ascension the balloonist he consulted put so unconscionable a price on one ascent that he bought an automobile instead—one of the first made, for this was in 1891—and with it returned to Brazil. It was not until six years later that, his ambition newly fired by reading of AndrÉe's plans for reaching the Pole in a balloon, Santos-Dumont took up anew his ambition to become an aviator. His own account of his first ascent does not bear precisely the hall-mark of the enthusiast too rapt in ecstasy to think of common things. "I had brought up," he notes gravely, "a substantial lunch of hard-boiled eggs, cold roast beef and chicken, cheese, ice cream, fruits and cakes, champagne, coffee, and chartreuse!" The balloon with its intrepid voyagers nevertheless returned to earth in safety. Amateur he may have been, was indeed throughout the greater part of his career as an airman. Nevertheless Santos-Dumont has to his credit two very notable achievements. He was the first constructor and pilot of a dirigible balloon that made a round trip, that is to say returned to its starting place after rounding a stake at some distance—in this instance the Eiffel Tower, 3-½ miles from St. Cloud whence Santos-Dumont started and whither he returned within half an hour, the time prescribed. This was not, indeed, the first occasion on which a round trip, necessitating operation against the wind on at least one course, had been made. In 1884 Captain Renard had accomplished this feat for the first time with the fish-shaped balloon La France, driven by an electric motor of nine horse-power. But though thus antedated in his exploit, Santos-Dumont did in fact accomplish more for the advancement and development Moreover by his personal qualities, no less than by his successful demonstration of the possibilities inherent in the dirigible, Santos-Dumont persuaded the French Government to take up aeronautics again, after abandoning the subject as the mere fad of a number of visionaries. Turning from balloons to airplanes the Brazilian was the first aviator to make a flight with a heavier-than-air machine before a body of judges. This triumph was mainly technical. The Wrights had made an equally notable flight almost a year before but not under conditions that made it a matter of scientific record. But setting aside for the time the work done by Santos-Dumont with machines heavier than air, let us consider his triumphs with balloons at the opening of his career. He had come to France about forty years after Henry Giffard had demonstrated the practicability of navigating a balloon 144 feet long and 34 feet in diameter with a three-horse-power steam-engine. But no material success attended this demonstration, important as it was, and the inventor turned his attention to captive balloons, operating one at the Paris Exposition of 1878 that took up forty passengers at a time. There followed Captain Renard to whose achievement we have already referred. He had laid
Santos-Dumont adopted all of these specifications, but added to them certain improvements which gave his airships—he built five of them before taking his first prize—notable superiority over that of Renard. To begin with he had the inestimable advantage of having the gasoline motor. He further lightened his craft by having the envelope made of Japanese silk, in flat defiance of all the builders of balloons who assured him that the substance was too light and its use would be suicidal. "All right," said the innovator to his favourite constructor, who refused to build him a balloon of that material, "I'll build it myself." In the face of this threat the builder capitulated. The balloon was built, and the silk proved to be the best fabric available at that time for the purpose. A keel made of strips of pine banded together with aluminum wire formed the backbone of the Santos-Dumont craft, and from it depended the car about one quarter of the One novel and exceedingly simple device bore witness to the ingenuity of the inventor. He had noticed in his days of free ballooning that to rise the aeronaut had to throw out sand-ballast; to descend he had to open the valves and let out gas. As his supply of both gas and sand was limited it was clear that the time of his flight was necessarily curtailed every time he ascended or descended. Santos-Dumont thought to husband his supplies of lifting force and of ballast, and make the motor raise and lower the ship. It was obvious that the craft would go whichever way the bow might be pointed, whether up or down. But how to shift the bow? The solution seems so simple that one wonders it ever perplexed aviators. From the peak of the bow and stern of his craft Santos-Dumont hung long ropes caught in the centre by lighter ropes by which they could be dragged into the car. In the car was carried a heavy bag of sand, which so long as it was there held the ship in a horizontal plane. Was it needful to depress the bow? Then the bow rope was hauled in, the bag attached, and swung out to a position where it would pull the forward tip of the delicately adjusted gas bag toward the earth. If only a gentle inclination was desired the bag was not allowed to hang directly under the bow, but was held at a point somewhere between the car and the bow so that the pull would be diagonal and the great cylinder would be diverted but little from the horizontal. If it were desired to ascend, a like manipulation of the ballast on the stern rope would depress the stern and point the bow upwards. For slight changes in direction The Deutsch prize which stimulated Santos-Dumont to his greatest achievements with dirigibles was a purse of twenty thousand dollars, offered by Mr. Henry Deutsch, a wealthy patron of the art of aviation. Not himself an aviator, M. Deutsch greatly aided the progress of the air's conquest. Convinced that the true solution of the problem lay in development of the gasoline engine, he expended large sums in developing and perfecting it. When he believed it was sufficiently developed to solve the problem of directing the flight of balloons he offered his prize for the circuit of the Eiffel Tower. The conditions of the contest were not easy. The competitor had to sail from the Aero Club at St. Cloud, pass twice over the Seine which at that point makes an abrupt bend, sail over the Bois de Boulogne, circle the Tower, and return to the stopping place within a half an hour. The distance was about seven miles, and it is noteworthy that in his own comment on the test Santos-Dumont complains that that required an average speed of fifteen miles an hour of which he could not be sure with his balloon. To-day dirigibles make sixty miles an hour, and airplanes not infrequently reach 130 miles. Moreover there could be no picking of a day on which atmospheric conditions were especially good. Mr. Deutsch had stipulated that the test must be made in the presence of a Scientific Commission whose members must be notified twenty-four hours in advance. None could tell twenty-four hours ahead what the air might be like, and as for utilizing the aviator's most favourable hour, the calm of the dawn, M. Santos-Dumont remarked: The craft with which the Brazilian first strove to win the Deutsch prize he called Santos-Dumont No. V. It was a cylinder, sharp at both ends, 109 feet long and driven by a 12-horse-power motor. A new feature was the use of piano wire for the support of the car, thus greatly reducing the resistance of the air which in the case of the old cord suspensions was almost as great as that of the balloon itself. Another novel feature was water ballast tanks forward and aft on the balloon itself and holding together twelve gallons. By pulling steel wires in the car the aviator could open the stop-cocks. The layman scarcely appreciates the very slight shift in ballast which will affect the stability of a dirigible. The shifting of a rope a few feet from its normal position, the dropping of two handfuls of sand, or release of a cup of water will do it. A humorous writer describing a lunch with Santos-Dumont in the air says: "Nothing must be thrown overboard, be it a bottle, an empty box or a chicken bone without the pilot's permission." After unofficial tests of his "No. 5" in one of which he circled the Tower without difficulty, Santos-Dumont summoned the Scientific Commission for a test. In ten minutes he had turned the Tower, and started back against a fierce head-wind, which made him ten minutes late in reaching the time-keepers. Just as he did so his engine failed, and after drifting for a time his ship perched in the top of a chestnut tree on the estate of M. Edmond Rothschild. Philosophical as ever the aeronaut clung to his craft, dispatched an excellent lunch which the Princess Isabel, Comtesse d'Eu, daughter of Dom Pedro, the deposed Emperor of The second trial for the Deutsch prize like the first ended in failure, but that failure was so much more dramatic even than the success which attended the third effort that it is worth telling and can best be told in M. Santos-Dumont's own words. The quotation is from his memoir, My Airships: And now I come to a terrible day—8th of August, 1901. At 6:30 A.M. in presence of the Scientific Commission of the Aero Club, I started again for the Eiffel Tower. I turned the tower at the end of nine minutes and took my way back to St. Cloud; but my balloon was losing hydrogen through one of its two automatic gas valves whose spring had been accidentally weakened. I had perceived the beginning of this loss of gas even before reaching the Eiffel Tower, and ordinarily, in such an event, I should have come at once to earth to examine the lesion. But here I was competing for a prize of great honour and my speed had been good. Therefore I risked going on. The balloon now shrunk visibly. By the time I had got back to the fortifications of Paris, near La Muette, it caused the suspension wires to sag so much that those nearest to the screw-propeller caught in it as it revolved. I saw the propeller cutting and tearing at the wires. I stopped the motor instantly. Then, as a consequence, the airship was at once driven back toward the tower by the wind which was strong. Photo by International Film Service Co. A Kite Balloon Rising from the Hold of a Ship. At the same time I was falling. The balloon had lost much gas. I might have thrown out ballast and greatly diminished the fall, but then the wind would have time to blow me back on the Eiffel Tower. I therefore preferred Why was the balloon fluttering an empty end causing all this extra danger? How was it that the rotary ventilator was not fulfilling its purpose in feeding the interior air balloon and in this manner swelling out the gas balloon around it? The answer must be looked for in the nature of the accident. The rotary ventilator stopped working when the motor itself stopped, and I had been obliged to stop the motor to prevent the propeller from tearing the suspension wires near it when the balloon first began to sag from loss of gas. It is true that the ventilator which was working at that moment had not proved sufficient to prevent the first sagging. It may have been that the interior balloon refused to fill out properly. The day after the accident when my balloon constructor's man came to me for the plans of a "No. 6" balloon envelope I gathered from something he said that the interior balloon of "No. 5," not having been given time for its varnish to dry before being adjusted, might have stuck together or stuck to the sides or bottom of the outer balloon. Such are the rewards of haste. I was falling. At the same time the wind was carrying me toward the Eiffel Tower. It had already carried me so far that I was expecting to land on the Seine embankment beyond the Trocadero. My basket and the whole of the keel had already passed the Trocadero hotels, and had my balloon been a spherical one it would have cleared the building. But now at the last critical moment, the end of the long balloon that was still full of gas came slapping I had made a mistake in my estimate of the wind's force, by a few yards. Instead of being carried on to fall on the Seine embankment, I now found myself hanging in my wicker basket high up in the courtyard of the Trocadero hotels, supported by my airship's keel, that stood braced at an angle of about forty-five degrees between the courtyard wall above and the roof of a lower construction farther down. The keel, in spite of my weight, that of the motor and machinery, and the shock it had received in falling, resisted wonderfully. The thin pine scantlings and piano wires of Nice (the town where the idea of a keel first suggested itself) had saved my life! After what seemed tedious waiting, I saw a rope being lowered to me from the roof above. I held to it and was hauled up, when I perceived my rescuers to be the brave firemen of Paris. From their station at Passy they had been watching the flight of the airship. They had seen my fall and immediately hastened to the spot. Then, having rescued me, they proceeded to rescue the airship. The operation was painful. The remains of the balloon envelope and the suspension wires hung lamentably; and it was impossible to disengage them except in strips and fragments! The later balloon "No. VI." with which Santos-Dumont won the Deutsch prize may fairly be taken as his conception of the finished type of dirigible for one man. In fact his aspirations never soared as high as those of Count Zeppelin, and the largest airship he ever planned—called "the Omnibus"—carried only four men. It is probable that the diversion of his interest from dirigibles to airplanes had most to do with his failure to carry his development further than he did. In a sense the reference to the heavens is a trifle over-rhetorical. Santos-Dumont differed from all aviators (or pilots of airplanes) and most navigators of dirigibles in always advocating the strategy of staying near the ground. In his flights he barely topped the roofs of the houses, and in his writings he repeatedly refers to the sense of safety that came to him when he knew he was close to the tree tops of a forest. This may have been due to the fact that in his very first flight in a dirigible he narrowly escaped a fatal accident due to flying too high. As he descended, the gas which had expanded now contracted. The balloon began to collapse in the middle. Cords subjected to unusual stress began to snap. The air pump, which should have pumped the ballonet full of air to keep the balloon rigid failed to work. Seeing that he was about to fall into a field in which his drag rope was already trailing the imperilled airman had a happy thought. Some boys were there flying kites. He shouted to them to seize his rope and run against the wind. The balloon responded to the new force like a kite. The rapidity of its fall was checked, and its pilot landed with only a serious shaking. But thereafter Santos-Dumont preached the maxim—rare among airmen—"Keep near the ground. That way lies safety!" Most aviators however, prefer the heights of the atmosphere, as the sailor prefers the wide and open sea to a course near land. After winning the Deutsch prize, Santos-Dumont continued Though before losing his interest in dirigibles Santos-Dumont carried the number of his construction up to ten, he cannot be said to have devised any new and useful improvements after his "No. VI." The largest of his ships was "No. X.," which had a capacity of eighty thousand cubic feet—about ten times the size of the little runabout with which he played pranks in Paris streets. In this balloon he placed partitions to prevent the gas shifting to one part of the envelope, and to guard against losing it all in the event of a tear. The Despite his great personal popularity the airship built by Santos-Dumont never appealed to the French military authorities. Probably this was largely due to the fact that he never built one of a sufficient size to meet military tests. The amateur in him was unconquerable. While von Zeppelin's first ship was big enough to take the air in actual war the Frenchman went on building craft for one or two men—good models for others to seize and build upon, but nothing which a war office could actually adopt. But he served his country well by stimulating the creation of great companies who built largely upon the foundations he had laid. First and greatest of these was the company formed by the Lebaudy Brothers, wealthy sugar manufacturers. Their model was semi-rigid, that is, provided with an inflexible keel or floor to the gas bag, which was cigar shaped. The most successful of the earlier ships was 190 feet long, with a car suspended by cables ten feet Her partner ship La RÉpublique had a like tragic end. She too made many successful trips, and proved her stability and worth. But one day while manoeuvring near Paris one of her propellers broke and tore a great rent in her envelope. As the Titanic, her hull ripped open by an iceberg, sunk with more than a Two airships were built in France for England in 1909. One, the Clement-Bayard II., was of the rigid type and built for the government; the other, a Lebaudy, was non-rigid and paid for by popular subscriptions raised in England by the Morning Post. Both were safely delivered near London having made their voyages of approximately 242 miles each at a speed exceeding forty miles an hour. These were the first airships acquired for British use. In the United States the only serious effort to develop the dirigible prior to the war, and to apply it to some definite purpose, was made not by the government but by an individual. Mr. Walter Wellman, a distinguished journalist, fired by the effort of AndrÉe to reach the North Pole in a drifting balloon, undertook a similar expedition with a dirigible in 1907. A balloon was built 184 feet in length and 52 feet in diameter, and was driven by a seventy-to eighty-horse-power motor. A curious feature of this craft was the guide rope or, as Wellman called it, the equilibrator, which was made of steel, jointed and hollow. At the lower end were four steel cylinders carrying wheels and so arranged that they would float on water or trundle along over the roughest ice. The idea was that the equilibrator would serve like a guide rope, trailing on the water or ice when the balloon hung low, and increasing the power of its drag if the balloon, rising higher, lifted a greater part of its length into the air. Wellman had every possible appliance to contribute to the safety of the airship, and many believe that had fortune favoured him the glory of the discovery of the Pole would have Neither Great Britain nor the United States has reason to be proud of the attitude of its government towards the inventors who were struggling to subdue the air to the uses of man. Nor has either reason to boast much of its action in utterly ignoring up to the very day war broke that aid to military service of which So far as the development of dirigible balloons is concerned there is no more need to devote space to what was done in England and the United States than there was for the famous chapter on Snakes in Iceland. |
