Open the door at once, father, said the voice outside sternly. 鈥業 beg your pardon, Miss Edith. I did, several seasons while you were still at school.鈥? Platz, a German soldier, attempting an ascent on the Tempelhofer Field in the Schwartz airship in 1897, merely proved the dirigible a failure. The vessel was of aluminium, 0.008 inch in thickness, strengthened by an aluminium lattice work; the motor was two-cylindered petrol-driven; at the first trial the metal developed such leaks that the vessel came to the ground within four miles of its starting point. Platz, who was aboard341 alone as crew, succeeded in escaping by jumping clear before the car touched earth, but the shock of alighting broke up the balloon, and a following high wind completed the work of full destruction. A second account says that Platz, finding the propellers insufficient to drive the vessel against the wind, opened the valve and descended too rapidly. Prior to the war period, between the years 1910 and 1914, a German undertaking called the Deutsche Luftfahrt Actien Gesellschaft conducted a commercial Zeppelin service in which four airships known as the Sachsan, Hansa, Victoria Louise, and Schwaben were used. During the four years of its work, the company carried over 17,000 passengers, and over 100,000 miles were flown without incurring one fatality and with only minor and unavoidable accidents to the vessels composing the service. Although a number of English notabilities made voyages in these airships, the success of this only experiment in commercial aerostation seems to have been forgotten since the war. There was beyond doubt a military aim in this apparently peaceful use of Zeppelin airships; it is past question now that all Germany鈥檚 mechanical development in respect of land, sea, and air transport in the years immediately preceding the war, was accomplished with the ulterior aim of military conquest, but, at the same time, the running of this service afforded proof of the possibility of establishing a dirigible service for peaceful ends, and afforded proof too, of the value of the dirigible as a vessel of purely commercial utility. In England Lilienthal鈥檚 work was carried on by Percy Sinclair Pilcher, who, born in 1866, completed six years鈥?service in the British Navy by the time that he was nineteen, and then went through a course of engineering, subsequently joining Maxim in his experimental work. It was not until 1895 that he began to build the first of the series of gliders with which he earned his plane among the pioneers of flight. Probably the best account of Pilcher鈥檚 work is that given in the Aeronautical Classics issued by the Royal Aeronautical Society, from which the following account of Pilcher鈥檚 work is mainly abstracted.2 鈥極r who would make the most of it if they had,鈥?Edith retorted sharply, adding in a low voice, 鈥楪aston, I quite hate you to-night: how disagreeable you can be.鈥? 成年片黄色大片网站视频 - 视频 - 在线观看 - 影视资讯 - 品善网 Zampa once started meant a noisy evening. Captain[Pg 176] Pentreath would sing "The Maid of Llangollen," and "Drink, puppy, drink." Mary Baynham would murder "It was a dream," and scream the higher notes in "Ruby." Duet would follow solo, and fantasia succeed ballad, Mrs. Baynham's idea of a social gathering being the nearest attainable approach to a penny reading. She would have had recitations, and imitations of popular actors, had there been any one capable of providing that form of amusement. 鈥榃ill the airship be able to rise out of rifle range? I have always been the first to insist that the normal place of the airship is in low altitudes, and I shall have written this book to little purpose if I have not shown the reader the real dangers attending any brusque vertical mounting to considerable heights. For this we have the terrible347 Severo accident before our eyes. In particular, I have expressed astonishment at hearing of experimenters rising to these altitudes without adequate purpose in their early stages of experience with dirigible balloons. All this is very different, however, from a reasoned, cautious mounting, whose necessity has been foreseen and prepared for.鈥? Madam! I see that you are speaking satirically, Ancram, but I don't know why. CHAPTER I
