"Free!" exclaimed Uncle Prudent.
"Yes--within the limits of the "Albatross!"
Uncle Prudent and Phil Evans rushed out of their prison. And what did
they see?
Four thousand feet below them the face of a country they sought in
vain to recognize.
Chapter VII
ON BOARD THE ALBATROSS
"When will man cease to crawl in the depths to live in the azure and
quiet of the sky?"
To this question of Camille Flammarion's the answer is easy. It will
be when the progress of mechanics has enabled us to solve the problem
of aviation. And in a few years--as we can foresee--a more
practical utilization of electricity will do much towards that
solution.
In 1783, before the Montgolfier brothers had built their
fire-balloon, and Charles, the physician, had devised his first
aerostat, a few adventurous spirits had dreamt of the conquest of
space by mechanical means. The first inventors did not think of
apparatus lighter than air, for that the science of their time did
not allow them to imagine. It was to contrivances heavier than air,
to flying machines in imitation of the birds, that they trusted to
realize aerial locomotion.
This was exactly what had been done by that madman Icarus, the son of
Daedalus, whose wings, fixed together with wax, had melted as they
approached the sun.
But without going back to mythological times, without dwelling on
Archytas of Tarentum, we find, in the works of Dante of Perugia, of
Leonardo da Vinci and Guidotti, the idea of machines made to move
through the air. Two centuries and a half afterwards inventors began
to multiply. In 1742 the Marquis de Bacqueville designed a system of
wings, tried it over the Seine, and fell and broke his arm. In 1768
Paucton conceived the idea of an apparatus with two screws,
suspensive and propulsive. In 1781 Meerwein, the architect of the
Prince of Baden, built an orthopteric machine, and protested against
the tendency of the aerostats which had just been invented. In 1784
Launoy and Bienvenu had maneuvered a helicopter worked by springs. In
1808 there were the attempts at flight by the Austrian Jacques Degen.
In 1810 came the pamphlet by Denian of Nantes, in which the
principles of "heavier than air" are laid down. From 1811 to 1840
came the inventions and researches of Derblinger, Vigual, Sarti,
Dubochet, and Cagniard de Latour. In 1842 we have the Englishman
Henson, with his system of inclined planes and screws worked by
steam. In 1845 came Cossus and his ascensional screws. In 1847 came
Camille Vert and his helicopter made of birds' wings. in 1852 came
Letur with his system of guidable parachutes, whose trial cost him
his life; and in the same year came Michel Loup with his plan of
gliding through the air on four revolving wings. In 1853 came
B�l�guic and his aeroplane with the traction screws,
Vaussin-Chardannes with his guidable kite, and George Cauley with his
flying machines driven by gas. From 1854 to 1863 appeared Joseph
Pline with several patents for aerial systems. Br�ant, Carlingford,
Le Bris, Du Temple, Bright, whose ascensional screws were
left-handed; Smythies, Panafieu, Crosnier, &c. At length, in 1863,
thanks to the efforts of Nadar, a society of "heavier than air" was
founded in Paris. There the inventors could experiment with the
machines, of which many were patented. Ponton d'Am�court and his
steam helicopter, La Landelle and his system of combining screws with
inclined planes and parachutes, Louvri� and his aeroscape, Esterno
and his mechanical bird, Groof and his apparatus with wings worked by
levers. The impetus was given, inventors invented, calculators
calculated all that could render aerial locomotion practicable.
Bourcart, Le Bris, Kaufmann, Smyth, Stringfellow, Prigent, Danjard,
Pom�s and De la Pauze, Moy, P�naud, Jobert, Haureau de Villeneuve,
Achenbach, Garapon, Duchesne, Danduran, Pariesel, Dieuaide,
Melkiseff, Forlanini, Bearey, Tatin, Dandrieux, Edison, some with
wings or screws, others with inclined planes, imagined, created,
constructed, perfected, their flying machines, ready to do their
work, once there came to be applied to thereby some inventor a motor
of adequate power and excessive lightness.
