And a trailer is impracticable when navigating great heights. For these reasons the development of the balloon lagged, until Count Zeppelin and M. Santos-Dumont consecrated their fortunes, their inventive minds, and their amazing courage to the task of perfecting a dirigible.
At such an angle it was impossible for those on board to use their rapid-fire gun, and Frank, setting the Golden Eagle's rising planes, soared rapidly along at an elevation of about two hundred feet. By the time the men on the dirigible had got her round, the Golden Eagle was two miles ahead of the gas-suspended craft. "We've escaped them," cried Harry.
The building of a modern rigid is an exceedingly costly undertaking, and the provision of an efficient supply of hydrogen gas to keep its compartments filled is a very large item in upkeep of which the heavier-than-air machine goes free. Yet the future of commercial aeronautics so far would seem to lie with the dirigible where very long voyages are in question.
But an actual trial of a dirigible craft, the design of Admiral Labrousse, was made from the Orleans railway station on January 9th. This machine consisted of a balloon of about the standard capacity of the siege balloons, namely some 70,000 cubic feet, fitted with two screws of about 12 feet diameter, but capable of being readily worked at moderate speed. It was not a success.
Without a stop the Golden Eagle winged steadily toward the northeast, and as the wonderful polar sunset was beginning to paint the western sky they made out the black form of the disabled dirigible on the snow barrens not far from the Viking ship's gully.
Their investigations were responsible for the inauguration of the elaborate German aerial patrol of harbours, the base for such aerial operations being established upon the island of Heligoland. So far the stern test of war as applied to the science of aeronautics has emphasised the fact that as a naval unit the dirigible is a complete failure.
It established the relative value of the dirigible and the airplane, so relegating the former to the rear that it is said that the death of Count Zeppelin, March 8, 1917, was in a measure due to his chagrin and disappointment. It stimulated at once the inventiveness of the constructors and the skill and daring of the pilots.
My dear fellow, the science of the aerostation of dirigible balloons is not yet developed enough for me to consider it and suppose that a murderer would drop from the clouds! So don't say a thing is possible, when it could not be otherwise. We know now how the man entered by the window, and we also know the moment at which he entered, during the five o'clock walk of the professor and his daughter.
Napier died, a year before Ned's meeting with the Major, it was discovered that he was making in his little shop a small dirigible balloon to be used at an amusement park. Mr. Napier's death was sudden. Manufacturer's bills for the balloon bag and engine came due and Ned, young as he was, knew that he must pay them.
Even as the onlookers gazed horror-stricken at the sudden blotting out of the dirigible before their eyes the loud roar of the explosion of its superheated gas reached their ears. "Every pound of steam you've got, chief," sharply commanded Captain Barrington, almost before the dirigible vanished, "we must save them yet."
