Up in the Clouds: Balloon Voyages

by R. M. Ballantyne

The chief differences between a parachute and an umbrella lie in the great size of the former, and in the cords which stretch from the outer points of its ribs to the lower end of the handle. These cords give it strength, and prevent it from turning inside out. There is also a hole in the top of the parachute to allow some of the air to escape.

The first parachute was constructed by Blanchard in 1785, and a dog was the first living creature that descended in it, and reached the earth unhurt. Blanchard afterwards made a descent in person at Basle, and broke his leg in the fall.

The bold aeronaut Monsieur Garnerin next ventured to make the perilous descent. He visited London in 1802, and made several ascents in a balloon. During one of these, on the evening of the 2nd November, he cut himself adrift in his parachute when at a vast height. The parachute was made of white canvas, having thirty-two gores, which, when not in use, hung with its cords from a hoop near the top of the machine. When expanded, it formed a vast umbrella of twenty-three feet in diameter, with a small basket about four feet high, and two and a quarter wide, suspended below it. Monsieur Garnerin stood in this basket when his balloon mounted into the air from an enclosure near North Audley Street. The parachute hung like a curtain over his head, above it towered the balloon, beneath stood the anxious multitude.

Well might they gaze in breathless expectation! After floating for some time in the upper regions of the air, as if he dreaded to make the bold attempt, he cut the cord that fastened him to the balloon when at the height, probably, of about half a mile. At first the parachute remained closed and descended with frightful violence; then it burst open, and for some seconds tossed about to such an extent that the basket was sometimes thrown almost into a horizontal position. The wind carried it over Marylebone and Somerstown; it almost grazed some of the houses of Saint Pancras in passing, and finally came to the ground in a field with such violence that poor Garnerin was thrown on his face and severely cut and bruised. No wonder that we are told he received a terrible shock. He trembled violently, and blood flowed from his nose and ears. Nevertheless, the accident did not deter his daughter from afterwards making the descent several times—and in safety.

The cause of the irregularity and violence of Garnerin’s descent was the giving way of one of the stays, which had the effect of deranging the balance of the apparatus.

In 1837 Mr Cocking invented a new parachute, which he hoped would be free from the faults of the other. It may be described as being the reverse of that of Garnerin, being made in the form of an umbrella blown inside out. The resistance to the air, it was thought, would be sufficient to check the rapid descent, while its form would prevent the tendency to oscillate.

This parachute was 34 feet in diameter, and was distended by a strong hoop to prevent its closing. There was also a hole in the middle of it, about 6 feet in diameter. Mr Cocking started from Vauxhall Gardens on the 24th of July, and after ascending to a considerable height, cut himself loose from his balloon when over Blackheath. The parachute descended rapidly and vibrated with great violence; the large hoop broke, the machine collapsed, and the unfortunate aeronaut was killed, and his body dreadfully mutilated.

Fatal accidents of this kind were to be expected; nevertheless it is a fact that the disasters which have befallen aeronauts have been comparatively few, considering the extreme danger to which they are necessarily exposed, not only from the delicacy of the materials with which they operate and the uncertainty of the medium through which they move, but, particularly, because of the impossibility of giving direction to their air-ships, or to arrest their progress through space. Parachutes, however, are not so absolutely incapable of being directed as are balloons. Monsieur Nadar writes on this point as follows:—

“Let us consider the action of the parachute.

“A parachute is a sort of umbrella, in which the handle is replaced at its point of insertion by an opening intended to ease the excess of air, in order to avoid the strong oscillations, chiefly at the moment at which it is first expanded. Cords, departing symmetrically from divers points of the circumference, meet concentrically at the basket in which is the aeronaut. Above this basket, and at the entrance of the folded parachute, that is to say closed during the rise, a hoop of sufficient diameter is intended to facilitate, at the moment of the fall, the entrance of the air which, rushing in under the pressure, expands the folds more easily and rapidly.
