This second machine, however, was not a success, and it was not until 1897 that the second 'Avion, which was the third power-driven aeroplane of Ader's construction, was ready for trial.
There is one story of 1914 that must be included, however briefly, in any record of aeronautical achievement, since it demonstrates past question that to Professor Langley really belongs the honour of having achieved a design which would ensure actual flight, although the series of accidents which attended his experiments gave to the Wright Brothers the honour of first leaving the earth and descending without accident in a power-driven heavier-than-air machine.
A moderately firm surface is necessary for the machine to run along the ground; if the ground be soft or marly the wheels would sink in the soil, and serious accidents have resulted from the sudden stoppage of the forward motion due to this cause. With their first power-driven machine the Wrights made a series of very fine flights, at first in a straight line.
It has been proved conclusively in these later years of accomplished flight that the machine which Langley launched on the Potomac River in October of 1903 was fully capable of sustained flight, and only the accidents incurred in launching prevented its pilot from being the first man to navigate the air successfully in a power-driven machine.
Science has done part of it. By the invention of power-driven machines and by the distribution of the compact industries of the home through the scattered, innumerable business enterprises of the community, Science has given us, in place of a simple and near world, a complicated and distant one. It takes us longer to learn it. And till we have done that, to some degree, we are not mature.
"If any one had told me six months ago that we would have a farm within two miles of our county seat, fenced with wire and permanent concrete posts, with modern permanent fireproof buildings, all equipped with modern power-driven machines and owned by one of the happiest farmers I have ever had the pleasure of meeting, I should have been afraid that someone would have awakened me, for I would have been sure it was a dream.
Since the Egyptians had a few draft animals, and little if any power-driven machinery, energy needed to build massive stone temples, tombs and other public structures must have been supplied by the forced labor of Egyptians, their serfs and slaves. Egypt's history dawns on a well-organized society: The Old Kingdom, based on the productivity of the narrow, lush Nile Valley.
And there was not a power-driven ground vehicle anywhere in sight, nor anything man made in the air. Great carts trailed out to the unloading belt. They dumped bales of skins and ingots of metal, and more bales and more ingots. Those objects rode up to the air lock and vanished. Hoddan was ignored.
It is past question that the 'Avion' was capable of power-driven flight; whether it achieved it or no remains an unsettled problem.
"I play with those," she said. "Dress them in all sorts of things tissue-paper mostly. It seems easier to catch an idea small in the tips of my fingers, and then let it grow up. You have to find out for yourself how you can do things, don't you?" Then she took him out into the workroom, where there were more cutting-tables and power-driven sewing-machines.
