My Airships Part 4

THE REAL AND THE IMAGINARY DANGERS OF BALLOONING

One of the most astonishing adventures I had during this period of spherical ballooning took place directly over Paris.

I had started from Vaugirard with four invited guests in a large balloon constructed for me after I had tired of making solitary trips in the little "Brazil."

From the start there seemed to be very little wind. I rose slowly, seeking an air current. At 1000 metres (3/5 of a mile high) I found nothing. At 1500 metres (one mile) we still remained almost stationary.

Throwing out more ballast we rose to 2000 metres (1-1/4 mile), when a vagrant breeze started to take us over the centre of Paris.

When we had arrived at a point over the Louvre ... it left us! We descended ... and found nothing!

Then happened the ludicrous thing. In a blue sky without a cloud, bathed in sunlight, and with the faint yelps of all the dogs of Paris mounting to our ears, we lay becalmed! Up we went again, hunting an air current.

Down we went again, hunting an air current. Up and down, up and down!

Hour after hour pa.s.sed, and we remained always hanging, always over Paris!

At first we laughed. Then we grew tired. Then almost alarmed. At one time I had even the idea of landing in Paris itself, near the Gare de Lyon, where I perceived an open s.p.a.ce. Yet the attempt would have been dangerous, because my four companions could not be depended on for coolness in an emergency. They had not the ballooning habit.

Worst of all, we were now losing gas. Drifting slowly eastward hour after hour one by one the sacks of ballast had been emptied. By the time that we had reached the Vincennes wood we had begun to throw out miscellaneous objects--ballast-sacks, the luncheon-baskets, two light camp-stools, two kodaks, and a case of photographic plates!

All during this latter period we were quite low--not over 300 yards above the tree-tops. Now, as we sank lower, we had a real fright. Would not the guide rope at least curl itself around some tree and hold us there for hours? So we struggled to maintain our alt.i.tude above the tree-tops, until all at once a queer little wind gust took us over the Vincennes racecourse.

"Now is our time!" I exclaimed to my companions. "Hold fast!"

With this I pulled on the valve rope, and we came down with celerity but scarcely any shock.

Personally, I have felt not only fear but also pain and real despair in a spherical balloon. It has not been often, because no sport is more regularly safe and mild and pleasurable. Such real dangers as it has are confined usually to the landing, and the balloonist of experience knows how to meet them; while from its imaginary dangers in the air one is regularly very safe. Therefore the particular adventure, full of pain and fear, that I recall to mind was all the more remarkable in that it occurred in high alt.i.tude.

It happened at Nice in 1900, when I went up from the Place Ma.s.sena in a good-sized spherical balloon, alone, and intending to drift a few hours only amid the enchanting scenery of the mountains and the sea.

The weather was fine, but the barometer soon fell, indicating storm. For a time the wind took me in the direction of Cimiez, but as I rose it threatened to carry me out to sea. I threw out ballast, abandoned the current, and mounted to the height of about a mile.

Shortly after this I let the balloon go down again, hoping to find a safe air current, but when within 300 yards of the ground, near the Var, I noticed that I had ceased descending. As I had determined to land soon in any case I pulled on the valve rope and let out more gas. And here the terrible experience began.

I could not go down. I glanced at the barometer, and found, indeed, that I was going up. Yet I ought to be descending, and I felt--by the wind and everything--that I must be descending. Had I not let out gas?

To my great uneasiness I discovered only too soon what was wrong. In spite of my continuous apparent descent I was, nevertheless, being lifted by an enormous column of air rushing upward. While I fell in it I rose rapidly higher with it.

I opened the valve again; it was useless. The barometer showed that I had reached a still greater alt.i.tude, and I could now take account of the fact by the way in which the land was disappearing under me. I now closed the valve to save my gas. There was nothing but to wait and see what would happen.

The upward-rushing column of air continued to take me to a height of 3000 metres (almost 2 miles). I could do nothing but watch the barometer. Then, after what seemed a long time, it showed that I had begun descending.

When I began to see land I threw out ballast, not to strike the earth too quickly. Now I could perceive the storm beating the trees and shrubbery. Up in the storm itself I had felt nothing.

Now, too, as I continued falling lower, I could see how swiftly I was being carried laterally. By the time I perceived the coming danger I was in it. Carried along at a terrific rate, knocking against the tops of trees, and continually threatened with a painful death, I threw out my anchor. It caught in trees and shrubs and broke away. Had it been heavy timber all would have been over with me. As it chanced, I was dragged through the small trees and yielding shrubbery, my face a ma.s.s of cuts and bruises, my clothes torn from my back, in pain and strain, fearing the worst, and able to do nothing to save myself. Just as I had given myself up for lost the guide rope wound itself around a tree and held. I was precipitated from the basket, and fell unconscious. When I came to I had to walk some distance until I met some peasants. They helped me back to Nice, where I went to bed, and had the doctors sew me up.

During the early period when I was glad to make public ascents for my balloon constructor I had undergone a somewhat similar experience, and that by night. The ascent took place at Peronne, in the north of France, one stormy afternoon, quite late. Indeed, I started in spite of thunder threatening in the distance, a gloomy semi-twilight all around me, and the remonstrances of the public, among whom it was known that I was not an aeronaut by trade. They feared my inexperience, and wished me either to renounce the ascent or else to oblige me to take up the balloon constructor with me, he being the responsible organiser of the _fete_.

I would listen to nothing, and started off as I had planned. Soon I had cause to regret my rashness. I was alone, lost in the clouds, amid flashes of lightning and claps of thunder, in the rapidly-approaching darkness of the night!

On, on I went tearing in the blackness. I knew that I must be going with great speed, yet felt no motion. I heard and felt the storm. I formed a part of the storm. I felt myself in great danger, yet the danger was not tangible. With it there was a fierce kind of joy. What shall I say? How shall I describe it? Up there in the black solitude, amid the lightning flashes and the thunderclaps, I was a part of the storm.

When I landed the next morning--long after I had sought a higher alt.i.tude and let the storm pa.s.s on beneath me--I found that I was well into Belgium. The dawn was peaceful, so that my landing took place without difficulty. I mention this adventure because it was made account of in the papers of the time, and to show that night ballooning, even in a storm, may be more dangerous in appearance than reality. Indeed, night ballooning has a charm that is all its own.

One is alone in the black void--true, in a murky limbo, where one seems to float without weight, without a surrounding world--a soul freed from the weight of matter. Yet now and again there are the lights of earth to cheer one. We see a point of light far on ahead. Slowly it expands. Then where there was one blaze there are countless bright spots. They run in lines, with here and there a brighter cl.u.s.ter. We know that it is a city.

Then, again, it is out into the lone land, with only a faint glow here and there. When the moon rises we see, perhaps, a faint curling line of grey. It is a river, with the moonlight falling on its waters.

There is a flash upward and a faint roar. It is a railway train, the locomotive's fires, maybe, illuminating for a moment its smoke as it rises.

Then for safety we throw out more ballast, and rise through the black solitudes of the clouds into a soul-lifting burst of splendid starlight.

There, alone with the constellations, we await the dawn.

And when the dawn comes, red and gold and purple in its glory, one is almost loth to seek the earth again, although the novelty of landing in who knows what part of Europe affords still another unique pleasure.

For many the great charm of all ballooning lies here. The balloonist becomes an explorer. Say that you are a young man who would roam, who would enjoy adventures, who would penetrate the unknown and deal with the unexpected--but say that you are tied down at home by family and business. I advise you to take to spherical ballooning. At noon you lunch peaceably amid your family. At 2 P.M. you mount. Ten minutes later you are no longer a commonplace citizen--you are an explorer, an adventurer of the unknown as truly as they who freeze on Greenland's icy mountains or melt on India's coral strand.

You know but vaguely where you are and cannot know where you are going. Yet much may depend upon your choice as well as your skill and experience. The choice of alt.i.tude is yours--whether to accept this current or mount higher and go with another. You may mount above the clouds, where one breathes oxygen from tubes, while the earth, in the last glimpse you had of it, seems to spin beneath you, and you lose all bearings; or you may descend and scud along the surface, aided by your guide rope and a dipperful of ballast to leap over trees and houses--giant leaps made without effort.

Then when the time comes to land there is the true explorer's zest of coming on unknown peoples like a G.o.d from a machine. "What country is this?" Will the answer come in German, Russian, or Norwegian? Paris Aero Club members have been shot at when crossing European frontiers.

Others, landing, have been taken prisoners to the burgomeister or the military governor, to languish as spies while the telegraph clicked to the far-off capital, and then to end the evening over champagne at an officers' enthusiastic mess. Still others have had to strive with the dangerous ignorance and superst.i.tion even of some remote little peasant population. These are the chances of the winds.

CHAPTER VI

I YIELD TO THE STEERABLE BALLOON IDEA

During my ascent with M. Machuron, while our guide rope was wrapped around the tree and the wind was shaking us so outrageously, he improved the occasion to discourage me against all steerable ballooning.

"Observe the treachery and vindictiveness of the wind," he cried between shocks. "We are tied to the tree, yet see with what force it tries to jerk us loose." (Here I was thrown again to the bottom of the basket.) "What screw propeller could hold a course against it? What elongated balloon would not double up and take you flying to destruction?"

It was discouraging. Returning to Paris by rail I gave up the ambition to continue Giffard's trials, and this state of mind lasted with me for weeks. I would have argued fluently against the dirigibility of balloons. Then came a new period of temptation, for a long-cherished idea dies hard. When I took account of its practical difficulties I found my mind working automatically to convince itself that they were not. I caught myself saying: "If I make a cylindrical balloon long enough and thin enough it will cut the air ..." and, with respect to the wind, "shall I not be as a sailing yachtsman who is not criticised for refusing to go out in a squall?"

At last an accident decided me. I have always been charmed by simplicity, while complications, be they never so ingenious, repel me.

Automobile tricycle motors happened to be very much perfected at the moment. I delighted in their simplicity, and, illogically enough, their merits had the effect of deciding my mind against all other objections to steerable ballooning.

"I will use this light and powerful motor," I said. "Giffard had no such opportunity."

Giffard's primitive steam-engine, weak in proportion to its weight, spitting red-hot sparks from its coal fuel, had afforded that courageous innovator no fair chance, I argued. I did not dally a single moment with the idea of an electric motor, which promises little danger, it is true, but which has the capital ballooning defect of being the heaviest known engine, counting the weight of its battery. Indeed, I have so little patience with the idea that I shall say no more about it except to repeat what Mr Edison said to me on this head in April 1902: "You have done well," he said, "to choose the petroleum motor. It is the only one of which an aeronaut can dream in the present state of the industry; and steerable balloons with electric motors, especially as they were fifteen or twenty years ago, could have led to no result. That is why the Tissandier brothers gave them up."

In spite of the recent immense improvements made in the steam-engine it would not have been able to decide me in favour of steerable ballooning.

Motor for motor it is, perhaps, better than the petroleum motor, but when you compare the boiler with the carburator the latter weighs grammes per horse-power while the boiler weighs kilogrammes. In certain light steam-motors, that are lighter even than petroleum motors, the boiler always ruins the proportion. With one pound of petroleum you can exert one horse-power during one hour. To get this same energy from the most improved steam-engine you will want many kilogrammes of water and of fuel, be it petroleum or other. Even condensing the water, you cannot have less than several kilogrammes per horse-power.

Then if one uses coal fuel with the steam-motor there are the burning sparks; while if one uses petroleum with burners you have a great amount of fire. We must do the petroleum motor the justice to admit that it makes neither flame nor burning sparks.
