Every year lighter and lighter gas-engines are being made, and this means that the surplus carrying power of the aeroplane can be increased. Fuel can be carried for flights of greater and greater distances, and rapid increases of speed can be attained. With improvements in safety there seems no limit to the possibilities of flight. So far a long train of casualties has marked the airship’s progress. This was inevitable when men came to imitate the birds, and trust themselves to the fickle currents of the air. But many aviators have been drawn from a reckless class, and many accidents have been due to a desire to thrill an audience rather than to learn more about the laws of flight. The Wrights have held to the wise course. They care nothing for spectacular performances or establishing new records for their own glory. Their work is in the shops, devising improvements that will make the airship safer and better fitted for commercial uses. They are men of remarkable balance, and it was their quality of unremitting care that made them the wonder of Europe, used above all things else to the dramatic in men’s flights through air.
