The chief interest in his design, though it never materialized, lies in the fact that it provided for a double envelope and was the precursor of the ballonet. The first man-carrying airship was built by Henri Giffard in 1852. It had a capacity of 87,000 cu. feet, a length of 144 feet, a 3 horse-power engine, and a speed of 6 miles an hour.
Like these others, however, he decided in 1896 that he would not undertake the construction of a large man-carrying machine. In addition to a multitude of actual duties, which left him practically no time available for original research, he had as an adverse factor fully ten years of disheartening difficulties in connection with his model machines.
Ellis relates how, when one was landed for the use of Pomare, the natives assisted to get it ashore, but when once landed they ran away and hid in fear of the "man-carrying pig." About this time Cook suffered from a bad attack of rheumatism in the legs, and was successfully treated by Otoo's mother, three sisters, and eight other women.
The truck was a trifle closer to the four man-carrying vehicles. They swept along, every man alert. They would pass forty feet below Lockley. He did nothing. His device was already turned on. He watched in detached calm. The lead car stopped as if it had run into a brick wall, while rifles inside it blew holes in its top. The second car crashed into it, rifles detonating. The third car.
With a series of over thirty rubber-driven models Langley demonstrated the practicability of opposing curved surfaces to the resistance of the air in such a way as to achieve flight, in the early nineties of last century; he then set about finding the motive power which should permit of the construction of larger machines, up to man-carrying size.
The first successful flight of a few seconds by one of their machines weighing 750 pounds was made in 1903. Two years afterward a flight of 24 miles was made at the rate of 38 miles an hour. Other successful experiments followed, and the claim of the Wrights to be considered the inventors of the first successful man-carrying flying machine was established.
As soon, however, as it reached the shore, the whole population took to flight, and tried to hide themselves from the man-carrying pig, as they christened the horse. A little higher up, the river divided itself into three little streams.

They collected all the theory available in the books published up to that time, and then built man-carrying gliders with which to test the data of Lilienthal and such other authorities as they had consulted.
This form of kite, consisting of two superposed surfaces connected at each end by a vertical panel or curtain of fabric, had proved extremely successful for man-carrying purposes, and, therefore, it was little wonder that several minds conceived the idea of attempting to fly by fitting a series of box-kites with an engine.
