My Airships Part 12

"I am astonished that the capital importance of this matter has not yet been grasped by all the professionals of aerostation. To mount in a balloon that one has not constructed, and which one is not in a state to guide, const.i.tutes the easiest of performances. A little cat has done it at the Folies-Bergere."

Now in war service overland the air-s.h.i.+p will, doubtless, have often to mount to considerable heights to avoid the rifle fire of the enemy, but, as the maritime auxiliary described by the expert of the French Navy, its scouting _role_ will for the most part be performed at the end of its guide rope, comparatively close to the waves, and yet high enough to take in a wide view. Only when for easily-imagined reasons it is desired to mount high for a short time will it quit the convenient contact of its guide rope with the surface of the sea.

For these considerations--and particularly the last--I was anxious to do a great deal of guide-roping over the Mediterranean. If the maritime experiment promises so much to spherical ballooning it is doubly promising to the air-s.h.i.+p, which, from the nature of its construction, carries comparatively little ballast. This ballast ought not to be currently sacrificed, as it is by the spherical balloonist, for the remedying of every little vertical aberration. Its purpose is for use in great emergencies. Nor ought the aerial navigator, particularly if he be alone, be forced to rectify his alt.i.tude continually by means of his propeller and s.h.i.+fting weights. He ought to be free to navigate his air-s.h.i.+p; if on pleasure bent, with ease and leisure to enjoy his flight; if on war service, with facility for his observations and hostile manoeuvres. Therefore any _automatic_ guarantee of vertical stability is peculiarly welcome to him.

You know already what the guide rope is. I have described it in my first experience of spherical ballooning. Overland, where there are level plains or roads or even streets, where there are not too many troublesome trees, buildings, fences, telegraph and trolley poles and wires and like irregularities, the guide rope is as great an aid to the air-s.h.i.+p as to the spherical balloon. Indeed, I have made it more so, for with me it is the central feature of my s.h.i.+fting weights (Figs. 8 and 9, page 148).

Over the uninterrupted stretches of the sea my first Monaco flight proved it to be a true _stabilisateur_. Its very slight dragging resistance through the water is out of all proportion to the considerable weight of its floating extremity. According to its greater or less immersion, therefore, it ballasts or unballasts the air-s.h.i.+p (Fig. 11). The balloon is held by the weight of the guide rope down to a fixed level over the waves without danger of being drawn into contact with them. For the moment that the air-s.h.i.+p descends the slightest distance nearer to them that very moment it becomes relieved of just so much weight, and must naturally rise again by that amount of momentary unballasting. In this way an incessant little tugging toward and away from the waves is produced, infinitely gentle, an automatic ballasting and unballasting of the air-s.h.i.+p without loss of ballast.

[Ill.u.s.tration: Fig. 11]

My first flight over the Mediterranean, which was made on the morning of 29th January 1902, proved more than this, unfortunately. It was seen that a miscalculation had been made with respect to the site of the aerodrome itself. In the navigation of the air, where all is new, such surprises meet the experimenter at every turn. This ought to be remembered when one takes account of progress. In the Paris-Madrid automobile race of 1903 what minute precautions were not taken to secure the compet.i.tors against the perils of quick turnings and grade crossings? And yet how notably insufficient did they not turn out to be.

As the air-s.h.i.+p was being taken out from its house for its first flight on the morning of 29th January 1902 the spectators could see that nothing equivalent to the landing-stages which the air-s.h.i.+ps of the future must have built for them existed in front of the building. The air-s.h.i.+p, loaded with ballast until it was a trifle heavier than the surrounding atmosphere, had to be towed, or helped, out of the aerodrome and across the Boulevard de la Condamine before it could be launched into the air over the sea wall.

Now that sea wall proved to be a dangerous obstruction. From the side walk it was only waist high, but on the other side of it the surf rolled over pebbles from four to five metres below.

The air-s.h.i.+p had to be lifted over the sea wall more than waist high; also, not to risk damaging the arms of its propeller, and when half over, there was no one to sustain it from the other side. Its stem pointed obliquely downward, while its stern threatened to grind on the wall. Scuffling among the pebbles below, on the sea side, half-a-dozen workmen held their arms high toward the descending keel as it was let down and pushed on toward them by the workmen in charge of it on the boulevard in front of the wall, and they were at last able to catch and right it only in time to prevent me from being precipitated from the basket.

For this reason my return to the aerodrome after this first flight became the occasion of a real triumph, for the crowd promptly took cognisance of the perils of the situation and foresaw difficulties for me when I should attempt to re-enter the balloon house. As there was no wind, however, and as I steered boldly, I was able to make a sensational entry without damage--and without aid. Straight as a dart the air-s.h.i.+p sped to the balloon house. The police of the prince had with difficulty cleared the boulevard between the sea wall and the wide-open doors. a.s.sistants and supernumeraries leaned over the wall with outstretched arms waiting for me; below on the beach were others, but this time I did not need them. I slowed the speed of the propeller as I came to them. Just as I was half way over the sea wall, well above them all, I stopped the motor. Carried onward by the dying momentum, the air-s.h.i.+p glided over their heads on toward the open door. They had grasped my guide rope to draw me down, but as I had been coming diagonally there was no need of it. Now they walked beside the air-s.h.i.+p into the balloon house, as its trainer or the stable-boys grasp the bridle of their racehorse after the course and lead him back in honour to the stable with his jockey in the saddle.

It was admitted, nevertheless, that I ought not to be obliged to steer so closely on returning from my flights--to enter the aerodrome as a needle is threaded by a steady hand--because a side gust of wind might catch me at the critical moment and dash me against a tree or lamp-post, or telegraph or telephone pole, not to speak of the sharp-cornered buildings on either side of the aerodrome. When I went out again for a short spin that same afternoon of 29th January 1902 the obstruction of the sea wall made itself only too evident. The prince offered to tear down the wall.

"I will not ask you to do so much," I said. "It will be enough to build a landing-stage on the sea side of the wall at the level of the boulevard."

This was done after twelve days of work, interrupted by persistent rain, and the air-s.h.i.+p, when it issued for its third flight, 10th February 1902, had simply to be lifted a few feet by men on each side of the wall. They drew it gently on until its whole length floated in equilibrium over the new platform that extended so far out into the surf that its farthermost piles were always in six feet of water.

Standing on this platform they steadied the air-s.h.i.+p while its motor was beings started, while I let out the overplus of water ballast and s.h.i.+fted my guide rope so as to point for an oblique drive upward. The motor began spitting and rumbling. The propeller began turning.

"Let go all!" I cried, for the third time at Monaco.

Lightly the air-s.h.i.+p slid along its oblique course, onward and upward.

Then as the propeller gathered force a mighty push sent me flying over the bay. I s.h.i.+fted forward the guide rope again to make a level course.

And out to sea the air-s.h.i.+p darted, its scarlet pennant fluttering symbolic letters as upon a streak of flame. They were the initial letters of the first line of Camoens' "Lusiad," the epic poet of my race:

Por mares nunca d'antes navegados!

(O'er seas hereto unsailed.)

CHAPTER XVIII

FLIGHTS IN MEDITERRANEAN WINDS

In my two previous experiments I had kept fairly within the wind-protected limits of the bay of Monaco, whose broad expanse afforded ample room both for guide-roping and practice in steering. Furthermore, a hundred friends and thousands of friendly spectators stood around it from the terraces of Monte Carlo to the sh.o.r.e of La Condamine and up the other side to the heights of Old Monaco. As I circled round and round the bay, mounted obliquely and swooped down, fetched a straight course, and then stopped abruptly to turn and begin again, their applause came up to me agreeably. Now, on my third flight, I steered for the open sea.

Out into the open Mediterranean I sped. The guide rope held me at a steady alt.i.tude of about 50 metres above the waves, as if in some mysterious way its lower end were attached to them.

In this way, automatically secure of my alt.i.tude, I found the work of aerial navigation become wonderfully easy. There was no ballast to throw out, no gas to let out, no s.h.i.+fting of the weights except when I expressly desired to mount or descend. So with my hand upon the rudder and my eye fixed on the far-off point of Cap Martin I gave myself up to the pleasure of this voyaging above the waves.

Here in these azure solitudes there were no chimney-pots of Paris, no cruel, threatening roof-corners, no tree-tops of the Bois de Boulogne.

My propeller was showing its power, and I was free to let it go. I had only to hold my course straight in the teeth of the breeze and watch the far-off Mediterranean sh.o.r.e flit past me.

I had plenty of leisure to look about. Presently I met two sailing yachts scudding towards me down the coast. I noticed that their sails were full-bellied. As I flew on over them, and they beneath me, I heard a faint cheer, and a graceful female figure on the foremost yacht waved a red foulard. As I turned to answer the politeness I perceived with some astonishment that we were far apart already.

I was now well up the coast, about half-way to Cap Martin. Above was the limitless blue void. Below was the solitude of white-capped waves.

From the appearance of sailing boats here and there I could tell that the wind was increasing to a squall, and I would have to turn in it before I could fly back upon it in my homeward trip.

Porting my helm I held the rudder tight. The air-s.h.i.+p swung round like a boat; then as the wind sent me flying down the coast my only work was to maintain the steady course. In scarcely more time than it takes to write it I was opposite the bay of Monaco again.

With a sharp turn of the rudder I entered the protected harbour, and amid a thousand cheers stopped the propeller, pulled in the forward s.h.i.+fting weight, and let the dying impetus of the air-s.h.i.+p carry it diagonally down to the landing-stage. This time there was no trouble. On the broad landing-stage stood my own men, a.s.sisted by those put at my disposition by the prince. The air-s.h.i.+p was grasped as it came gliding slowly to them, and, without actually coming to a stop, it was "led"

over the sea wall across the Boulevard de la Condamine and into the aerodrome. The trip had lasted less than an hour, and I had been within a few hundred metres (yards) of Cap Martin.

Here was an obvious trip, first against and then with a stiff wind, and the curious may render themselves an account of the fact by glancing at the two photographs marked "Wind A" and "Wind B." As they happened to be taken by a Monte Carlo professional intent simply on getting good photographs they are impartial.

"Wind A" shows me leaving the bay of Monaco against a wind that is blowing back the smoke of the two steamers seen on the horizon.

"Wind B" was taken up the coast just before I met the two little sailing yachts which are obviously scudding toward me.

The loneliness in which I found myself in the middle of this first extended flight up the Mediterranean sh.o.r.e was not part of the programme. During the manufacture of the hydrogen gas and the filling of the balloon I had received the visits of a great many prominent people, several of whom signified their ability and readiness to lend valuable aid to these experiments. From Beaulieu, where his steam-yacht, _Lysistrata_, was at anchor, came Mr James Gordon Bennett, and Mr Eugene Higgins had already brought the _Varuna_ up from Nice on more than one occasion. The beautiful little steam-yacht of M. Eiffel also held itself in readiness.

It had been the intention of these owners, as it had been that of the prince with his _Princesse Alice_, to follow the air-s.h.i.+p in its flights over the Mediterranean, so as to be on the spot in case of accident.

This first flight, however, had been taken on impulse before any programme for the yachts had been arranged, and my next long flight, as will be seen, demonstrated that this kind of protection must not be counted on overmuch by air-s.h.i.+p captains.

It was on the 12th of February 1902. One steam chaloupe and two petroleum launches, all three of them swift goers, together with three well-manned row-boats, had been stationed at intervals down the coast to pick me up in case of accident. The steam _chaloupe_ of the Prince of Monaco, carrying His Highness, the Governor-General, and the captain of the _Princesse Alice_, had already started on the course ahead of time.

The 40 horse-power Mors automobile of Mr Clarence Grey Dinsmore and the 30 horse-power Panhard of M. Isidore Kahenstein were prepared to follow along the lower coast road.

[Ill.u.s.tration: "WIND A"]

[Ill.u.s.tration: "WIND B"]

Immediately on leaving the bay of Monaco I met the wind head on as I steered my course straight down the coast in the direction of the Italian frontier. Putting on all speed I held the rudder firm and let myself go. I could see the ragged outlines of the coast flit past me on the left. Along the winding road the two racing automobiles kept abreast with me, being driven at high speed.

"It was all we could do to follow the air-s.h.i.+p along the curves of the coast road," said one of Mr Dinsmore's pa.s.sengers to the reporter of a Paris journal, "so rapid was its flight. In less than five minutes it had arrived opposite the Villa Camille Blanc, which is about a kilometre (3/4 of a mile) distant from Cap Martin as the crow flies.

"At this moment the air-s.h.i.+p was absolutely alone. Between it and Cap Martin I saw a single row-boat, while far behind was visible the smoke from the prince's _chaloupe_. It was really no commonplace sight to see the air-s.h.i.+p thus hovering isolated over the immense sea."

The wind instead of subsiding had been increasing. Here and there around the horizon I could see the bent white sails of yachts driven before it. The situation was new to me, so I made an abrupt turn and started back on the home stretch.

Now again the wind was with me, stronger than it had been on the preceding flight down the coast. Yet it was easy steering, and I remarked with pleasure that going thus with the wind the pitching or _tangage_ of the air-s.h.i.+p was much less. Though going fast with my propeller, and aided by the wind behind me, I felt no more motion, indeed even less, than before.

For the rest, how different were my sensations from those of the spherical balloonist! It is true that he sees the earth flying backward beneath him at tremendous speed. But he knows that he is powerless.

The great sphere of gas above him is the plaything of the air current, and he cannot change his direction by a hair's-breadth. In my air-s.h.i.+p I could see myself flying over the sea, but I had my hands on a helm that made me master of my direction in this splendid course. Once or twice, merely to give myself an account of it, I shoved the helm around a short arc. Obedient, the air-s.h.i.+p's stem swung to the other side, and I found myself speeding in a new diagonal course. But these manoeuvres only occupied a few instants each, and each time I swung myself back on a straight line to the entrance to the bay of Monaco, for I was flying homeward like an eagle, and must keep my course.
