Pilcher鈥檚 first glides, which he carried out on a grass hill on the banks of the Clyde near Cardross, gave little result, owing to the exaggerated dihedral angle of the wings, and the absence of a horizontal tail. The 鈥楤at鈥?was consequently reconstructed with a horizontal tail-plane added to the vertical one, and with the wings lowered so that the tips were only six inches above the level of the body. The machine now gave far better results; on the first glide into a head wind Pilcher rose to a height of twelve feet and remained in the air for a third of a minute; in the second attempt a rope was used to tow the glider, which rose to twenty feet and did not come to earth again until103 nearly a minute had passed. With experience Pilcher was able to lengthen his glide and improve his balance, but the dropped wing tips made landing difficult, and there were many breakages. [208] She answered so faintly that he had to strain his ear to hear her, and her colourless lips trembled as the lips tremble of a person trying to keep back tears. But her eyes were quite dry. pk10最稳买法 [208] America had its Army Aviation School, and employed Burgess-Wright and Curtiss machines for the most part. In the pre-war years, once the Wright Brothers had accomplished their task, America鈥檚 chief accomplishment consisted in the development of the 鈥楩lying242 Boat,鈥?alternatively named with characteristic American clumsiness, 鈥楾he Hydro-Aeroplane.鈥?In February of 1911, Glenn Curtiss attached a float to a machine similar to that with which he won the first Gordon-Bennett Air Contest and made his first flying boat experiment. From this beginning he developed the boat form of body which obviated the use and troubles of floats鈥攈is hydroplane became its own float. I had not much to say. I told him that I thought Diamond stood a good chance of getting Dorrington School. 鈥淚 feel, Mr. Chairman, that this is the most solemn moment of my life. I feel, I trust, in some measure the responsibilities which at this hour I sustain to these my fellow-citizens, to the church of which I am a minister, to my country, and to God. And let me beg of you, before I proceed further, to construe nothing I shall say as being disrespectful to this assembly. I have no such feeling; far from it. And if I do not act or speak according to their wishes at all times, it is because I cannot conscientiously do it. Oddly enough, she said, "I have been disappointed of a visitor this evening, and so should have been quite alone if you and Algy had not come in. I had asked Rhoda to spend the evening with me." [208] 鈥楾here stood our aerial prot茅g茅e in all her purity鈥攖oo delicate, too fragile, too beautiful for this rough world; at least those were my ideas at the time, but little did I think how soon it was to be realised. I soon found, before I had time to introduce the spark, a drooping in the wings, a flagging in all the parts. In less than ten minutes the machine was saturated with wet from a deposit of dew, so that anything like a trial was impossible by night. I did not consider we could get the silk tight and rigid enough. Indeed, the framework altogether was too weak. The steam-engine was the best part. Our want of success was not for want of power or sustaining surface, but for want of proper adaptation of the means to the end of the various parts.鈥?
