From earliest times, man has longed to navigate the air. He has watched with envy the free flight of birds, and has tried to imitate it, usually with disastrous results. The balloon, of course, enabled him to rise in the air, but once there, he was at the mercy of every wind. More recently, balloons fitted with motors and steering gear have been devised, which are to some extent dirigible; but the real problem has been to fly as birds do without any such artificial aid as balloons provide.

Experiments to solve this problem were begun several years ago by Professor S. P. Langley, of the Smithsonian Institution, under government supervision, and pointed the way to other investigators. He proved, theoretically, that air-flight was possible, provided sufficient velocity could be obtained. He showed that a heavier-than-air machine would sustain itself in the air if it could only be driven fast enough. You have all skipped flat stones across the water. Well, that is exactly the principle of the flying machine. As long as the stone went fast enough, it skipped along the top of the water, which sustained it and even threw it up into the air again. When its speed slackened, it sank. So the boy on skates can skim safely across thin ice which would not bear his weight for an instant if he tried to stand upon it.

So, theoretically, it was possible to fly, but to reduce theory to practice was a very different thing. Professor Langley tried for years and failed. He built a great machine, which plunged beneath the waters of the Potomac a minute after it was launched. All over the world, inventors were struggling with the problem, but nowhere with any great degree of success. It remained for two brothers, in a little workshop at Dayton, Ohio, to produce the first machine which would really fly.

Orville and Wilbur Wright were poor boys, the sons of a clergyman, and apparently in no way distinguished from ordinary boys, except by a taste for mechanics. They had a little workshop, and one day in 1905, they brought out a strange looking machine from it, and announced that it was a flying-machine. The people of Dayton smiled skeptically, and assembled to witness the demonstration with the thought that there would probably soon be need for an ambulance. The gasoline motor with which the machine was equipped, was started, one of the brothers climbed aboard and grasped the levers, the other dropped a weight which started the machine down a long incline. For a moment, it slid along, then its great forward planes caught the air current and it soared gracefully up into the air.

That was a great moment in human history, so great that the crowd looking on scarcely realized its import. They watched the machine with bated breath, and saw it steered around in a circle, showing that it could go against the wind as well as with it. For thirty-eight minutes it remained in the air, making a circular flight of over twenty-four miles. Then it was gently landed and the exhibition was over. Great crowds flocked to Dayton, after that, expecting to see further exhibitions, but they were disappointed. The machine had been taken back to the shop, and the young inventors announced that they were making some changes in it. No one was admitted to the shop, nor were any other flights made.

One day the inventors also disappeared, and months later it was discovered that they had built themselves a little shop on a deserted stretch of the sandy North Carolina coast, and that they were carrying on their experiments there, secure from observation. Enterprising reporters tried to interview them and failed; but, ambushed afar off, they one day saw the great machine soaring proudly in a wide circle above the sands. A photographer even got a distant photograph of it. There could be no doubt that the Wright brothers had solved the problem of flight.

But not for two years more were they ready for public exhibitions. Then, in 1908, they appeared at Fort Myer, Virginia, ready to take part in the contest set by the United States government. No one who was present on that first day will ever forget his sensations as the great winged creature rose gracefully from the ground and circled about in the air overhead. Again and again flights were made, sometimes with an extra passenger; great speed was attained and the machine was under perfect control. But an unfortunate accident put a stop to the trials, for one day a propellor-blade broke while the machine was in mid-air, and it struck the ground before it could be righted. The passenger, a member of the United States Signal Corps, was instantly killed and Orville Wright was seriously injured.

Meanwhile, the other brother, Wilbur, had gone to Europe, where, first in France, and afterwards in Italy and England, he created a tremendous sensation by his spectacular flights. They were uniformly successful. Not an accident marred them. The governments of Europe were quick to secure the right to manufacture the aeroplane; kings and princes vied with each other in honoring the young inventor, and when he returned to the United States, city, state, and nation combined in a great reception to him and to his brother.

As these lines are being written, in August, 1909, another series of flights has been concluded at Fort Myer. They were successful in every way in fulfilling the government tests, and the Wrights' machine was purchased by the government for $30,000. Everywhere air-ship flights are being made successfully, and it is only a question of time until the aeroplane becomes a common means of conveyance. Wilbur Wright declares that it is already safer than the automobile, and it would seem that there is in store for man a new and exquisite sensation, that of flight.

Surely, America has cause to be proud of her inventors!
