It was Jack's eye that had made out the only means of effective attack against the dirigible. Even as he had ordered the attack, the lad knew that it meant almost certain death, but he had not hesitated. He realized that the French aircraft must be shown some means of destroying these huge air fighters, and knowing that there was time to convey his ideas to the other, had acted at once.
For all working parts-Advisable. Commercial Minerals Co. 107 Minories If you have not Clothed YOURSELF in a HYMANS & GRAHAM 1198 Lower Broadway, New York * It is now nearly, a generation since the Plane was to supersede the Dirigible for all purposes. * TO-DAY none of the Planet's freight is carried en plane. * Less than two per rent of the Planet's passengers are carried en plane.
"I will also retain the aeroplane feature, so that the Black Hawk will be a combined biplane and dirigible balloon. But it will have many new features. I have the plans all drawn for a new style of gas generating apparatus, and I think it can be made in time." There were busy days about the Swift home. Mrs. Baggert, the housekeeper, was in despair.
It was higher than the boy had ever been before. For several minutes he was too busy easing the dirigible through a blast that seemed as if it would rip her apart to notice the gauge again. When he had an opportunity to do so, he gave a whistle of surprise. The dirigible had now climbed on the wings of the storm to an altitude of fourteen thousand feet.
They held steadily on their course that day and the next. Early in the morning of the second they encountered a surprising incident. Frank, who was on lookout, hailed "Air-ship ahead." And there, sure enough, heading northward, was a big red dirigible coming toward them like the wind. As they drew near, a man with a megaphone appeared on her bridge and signaled that he wanted to hail them.
After this accident minute calculations were made and it was ascertained that a potential difference of no less than 100,00 volts existed between the framework of the dirigible and the trees. This tension sufficed to produce a spark 4 inches in length.
While his men were getting ready for this test Tom bent over the broken propeller, looking from that to the recoil checks, which had not come up to expectations. Then he shook his head in a worried and puzzled manner. Dropping bombs from an aeroplane, or a dirigible balloon, is a comparatively simple matter.
It was operated by a motor driven by a bichromate of soda battery. The motor weighed 121 lbs. The cells held liquid enough to work for 2-1/2 hours, generating 1-1/3 horse power. The screw had two arms and was over nine feet in circumference. Tissandier made some successful flights. The first dirigible balloon to return whence it started was that known as La France.
He referred to a new device of his with which the Wondership was equipped for protecting balloon bags from lightning. In a thunderstorm a balloon, or gas-filled dirigible, is subject to sudden variations of electric charge which, under certain conditions, might produce sparks leading to its annihilation.
All this, however, assumes that the Schwartz type the first rigid dirigible, by the way would prove successful. As it proved a failure on the first trial, the problem of filling it did not arise again.
