The objection of inflammability of the lifting power has also been overcome. The power of the ordinary hydrogen gas in all its various forms has been multiplied threefold by a new dioxygen gas discovered at the Spandau government chemical laboratory. This gas has also the enormous advantages of being absolutely noninflammable. I have seen experiments made with it. It cannot be used for illuminating purposes. Dirigibles that are equipped with it are not liable to the awful explosions that have characterized flights under the ordinary system. The new gas has also the enormous advantage of having a liquid form. To produce the gas it is only necessary to let the ordinary atmosphere come in contact with the liquid. Carried in cylinders two feet long and with a diameter of six inches it is obvious that enough of this liquid can be carried aboard the big war dirigibles to permit their refilling in midair. So, you see, all the objections to the commonly known system of operation have been overcome by the War Office. The last dirigible tried by the War Office in 1912, the mysterious Zeppelin X, made a continuous trip from Stettin over the Baltic to Upsala in Sweden, thence across the Baltic again to Riga in the Gulf of Finland, where it doubled and sailed back to Stettin. This was a journey of 976 miles. The airship had a complement of twenty-five men and five tons of dead weight. It traveled under severe weather conditions, the month being March, and snow-storms, hail and rain occurring throughout the voyage. The significance of this flight can be easily understood if you consider the distance from Strassburg or Dusseldorf to Paris or other strategical points to France is approximately 298 miles. A ship like the Zeppelin X could sail over the French border, dynamite the fortifications around Paris and return, the journey being roughly 900 miles--76 miles less than the actual trip made by the Zeppelin X. Moreover, the German military trials have shown the possibility of an aerial fleet leaving their home ports and cruising to foreign lands and returning without the necessity of landing to replenish their gas tanks or fuel.
