First and greatest of these was the company formed by the Lebaudy Brothers, wealthy sugar manufacturers. Their model was semi-rigid, that is, provided with an inflexible keel or floor to the gas bag, which was cigar shaped. The most successful of the earlier ships was 190 feet long, with a car suspended by cables ten feet below the balloon and carrying the twin motors, together with passengers and supplies. Although it made many voyages without accident, it finally encountered what seems to be the chief peril of dirigible balloons, being torn from its moorings at Châlons and dashed against trees to the complete demolition of its envelope. Repaired in eleven weeks she was taken over by the French Department of War, and was in active service at the beginning of the war. Her two successors on the company's building ways were less fortunate. La Patrie, after many successful trips, and manoeuvres with the troops, was insecurely moored at Verdun, the famous fortress where she was to have been permanently stationed. Came up a heavy gale. Her anchors began to drag. The bugles sounded and the soldiers by hundreds rushed from the fort to aid. Hurled along by the wind she dragged the soldiers after her. Fearing disaster to the men the commandant reluctantly ordered them to let go. The ship leaped into the black upper air and disappeared. All across France, across that very country where in 1916 the trenches cut their ugly zigzags from the Channel to the Vosges, she drifted unseen. By morning she was flying over England and Wales. Ireland caught a glimpse of her and days thereafter sailors coming into port told of a curious yellow mass, seemingly flabby and disintegrating like the carcass of a whale, floating far out at sea.
Her partner ship La République had a like tragic end. She too made many successful trips, and proved her stability and worth. But one day while manoeuvring near Paris one of her propellers broke and tore a great rent in her envelope. As the Titanic, her hull ripped open by an iceberg, sunk with more than a thousand of her people, so this airship, wounded in a more unstable element, fell to the ground killing all on board.
Two airships were built in France for England in 1909. One, the Clement-Bayard II., was of the rigid type and built for the government; the other, a Lebaudy, was non-rigid and paid for by popular subscriptions raised in England by the Morning Post. Both were safely delivered near London having made their voyages of approximately 242 miles each at a speed exceeding forty miles an hour. These were the first airships acquired for British use.
