Experimental flight, he suggested, should be tried over water, in order to break any accidental fall; when a series of experiments had proved the stability of a glider, it would then be time to apply motive power.
They've done some high-altitude gliding already. The distance record took someone across the Atlantic in 2009, didn't it? But it seems that ten miles straight up is a bit too steep for a glider. There are no vertical air currents at that height." "I meant to say that his machine is not a true glider, but a semi-glider.
This morning a gosling from the old school a Sophomore came in and visited with me for a few minutes, on the strength of the fact that he knew my baby brother in high school. We hadn't talked a minute before he handed me "pragmatism" and "zing-slingers." While I was rolling my eyes and clawing for a foothold he confessed that he was the best glider in college.
Now that Lillenthal's experiments had proved conclusively the efficiency of wings, or planes, as carrying surfaces, other engineers followed in his footsteps, and tried to improve on his good work. The first "birdman" to use a glider in this country was Mr. Percy Pilcher who carried out his experiments at Cardross in Scotland.
This sky glider Tom would now use in going to the rescue of Mary Nestor was not, however, the same large craft that figured in the previous story. That airship had been given to the United States government for war purposes. But Tom had built himself a smaller one for his own use. It had the advantage of enabling him to carry on a conversation with his passenger when he took one aloft.
If he used a glider, the noise of the big plane so near would be more than enough to kill the slight sounds. The glider could hang above the ship, then dive down upon it as it passed beneath. He has a very simple system of anchoring the thing, as I discovered to my sorrow. It's a powerful electro-magnet which he turns on when he lands.
For the main supporting surfaces of the glider the biplane system of Chanute's gliders was adopted with certain modifications, while the curve of the wings was founded upon the calculations of Lilienthal as to wind pressure and consequent lift of the plane.
At last the great skyscrapers of San Francisco appeared on their horizon, and thousands of private planes started out to meet them. Frantically Arcot warned them away, lest the air blast from their props tear the glider from the magnet. At last, however, the Air Guard was able to force them to a safe distance and clear a lane through one of the lower levels of the city traffic.
All the time that the Wrights were experimenting with their glider and biplane in America, and the Voisin brothers were constructing biplanes in France, Bleriot had been giving earnest attention to the production of a real "bird" machine, provided with one pair of FLAPPING wings.
One flies by the seat of his pants, in a soaring glider, and Joe flew his as though born in it. The others, obviously, were as yet not thoroughly used to engineless craft. He banked away from them, flying as judiciously as possible, begrudging each foot dropped.
