The experiments were conducted on San Diego Bay, and it was only after long and patient labour that the work of Mr. Curtiss and his military associates was rewarded with success. In the course of the experiments he tried a triplane, which had great lifting power, but this later was abandoned in favour of the regular biplane fitted with a float. After the machine had been perfected, Curtiss flew his hydro-aeroplane out into the bay to the cruiser Pennsylvania, upon which Ely had landed a month before, and after landing on the water at the cruiser's side was pulled up to her deck and later was put back into the water from where he sailed to camp. The machine was named the Triad because it had conquered air, land, and water.
Of the machine Curtiss says: "I believe the hydro-aeroplane represents one of the longest and most important strides in aviation. It robs the aeroplane of many of its dangers, and as an engine of warfare widens its scope of utility beyond the bounds of the most vivid imagination. The hydro-aeroplane can fly 60 miles an hour, skim the water at 50 miles and run over the earth at 35 miles."
It was not long after the Curtiss hydro-aeroplane had been successfully demonstrated, before all the other leading makers brought out air craft that could sail from and alight on water as well as on land. The Wright hydro-aeroplane, which is equipped with two long air-tight metal floats instead of one, has achieved great success in the United States. In Europe all the leading biplane types are now made with hydro-aeroplane equipment, and flying over water became as popular last year as flying over land did in 1910.
The first American monoplane to be equipped with the floats of a hydro-plane was shown by the "Queen" company at the New York Aero show in May, 1912. It was called an aero boat as the front part of the fuselage was enclosed like a boat and the operator sat in it, under the wings. The propeller was at the rear and there was a small pontoon at each end of the wings to keep it on an even keel when stationary in the water. A short time after this the Curtiss company turned out the flying boat which was described on page [90].
THE WORLD'S LONGEST GLIDE
