When the R.F.C. was founded鈥攁nd in fact up to two years after its founding鈥攊n no country were the full military potentialities of the aeroplane realised; it was regarded as an accessory to cavalry for scouting more than as an independent arm; the possibilities of bombing were very vaguely considered, and the fact that it might be possible to shoot from an aeroplane was hardly considered at all. The conditions of the British Military Trials of 1912 gave to the War Office the option of purchasing for 锟?,000 any machine that might be awarded a prize. Machines were required, among other things, to carry a useful load of 350 lbs. in addition to equipment, with fuel and oil for 4? hours; thus loaded, they were required to fly for 3 hours, attaining an altitude of 4,500 feet, maintaining a height of 1,500 feet for 1 hour, and climbing 1,000 feet from the ground at a rate of 200 feet per minute, 鈥榓lthough 300 feet per minute is desirable.鈥?They had to attain a speed of not less than 55 miles per hour in a calm, and be able to plane down to the ground in a calm from not more than 1,000 feet with engine stopped, traversing 6,000 feet horizontal distance. For those days, the landing demands were rather exacting; the machine should be able to rise without damage from long grass, clover, or harrowed land, in 100 yards in a calm, and should be able to land without damage on any cultivated ground, including rough ploughed land, and, when landing on smooth turf in a calm, be able to pull up236 within 75 yards of the point of first touching the ground. It was required that pilot and observer should have as open a view as possible to front and flanks, and they should be so shielded from the wind as to be able to communicate with each other. These are the main provisions out of the set of conditions laid down for competitors, but a considerable amount of leniency was shown by the authorities in the competition, who obviously wished to try out every machine entered and see what were its capabilities. What o'clock shall we say, Castalia? asked her husband, as they alighted at Mrs. Thimbleby's door. I am glad to hear it. But鈥攚ill you forgive the liberty I am taking for the sake of my motive, and give me carte blanche to be as impertinent as I please. Good gracious, no! He doesn't think of minding you at all. I wonder whether you will care to hear of some good news I had to-day? Mr. Diamond is a gentleman, father. Everybody allows that. 黄网址在线播放_国产一本到在线 Lord Seely made no immediate reply to his wife's suggestion. He was ill and grieved, and he felt as if his final exit from this world of troubles might not be altogether undesirable. His interview with Algernon had agitated him terribly. His interview with his wife鈥攁lthough she had opened the door for a ray of hope that things might be not quite so terribly bad as he had feared鈥攈ad certainly not soothed him. But before the departure of the evening mail that night, he had completed and despatched a letter to Castalia. He had insisted on writing it with his own hand, sitting up in bed to do so, although his fingers were scarcely able to guide the pen. From London Lord Seely鈥攚ho had heard that Miss Bodkin had visited Duckwell Farm while his niece lay dead there, and had placed flowers on her unconscious breast鈥攕ent a mourning-ring and a letter, the contents of which Minnie communicated to no one but her parents. Nevertheless, its contents were discussed pretty widely, and were said to be of a nature very damnatory to Algernon Errington's character. However, the painful things that were said in Whitford could not hurt him, for he had gone鈥攄isappeared in the night like a thief, as his creditors said鈥攁nd no one could say whither. Stagnation followed until early in 1909, when a small airship fitted with two 12 horse-power motors and named the 鈥楤aby鈥?was turned out from the balloon factory. This was almost egg-shaped, the blunt end being forward, and three inflated fins being placed at the tail as control members. A long car with rudder and elevator at its rear-end carried the engines and crew; the 鈥楤aby鈥?made some fairly successful flights and gave a good deal of useful data for the construction of later vessels. Weasel. Sir, my Mistress begs you to walk up. The 鈥楻epublique鈥?had an 80 horse-power motor, which, however, only gave her the same speed as the 鈥楶atrie.鈥?She was launched in July, 1908, and within three months came to an end which constituted a tragedy for France. A propeller burst while the vessel was in the air, and one blade, flying toward the envelope, tore in it a great gash; the airship crashed to earth, and the two officers and two non-commissioned officers who were in the car were instantaneously killed.
