The Antoinette monoplane was evolved from the early experiments of MM. Gastambide and Mangin, and designed by the famous M. Levavasseur, the engine as well as the aeroplane. This is the plane in which Herbert Latham failed to cross the English Channel by only a few hundred yards. At the Rheims meeting in August, 1909, it was in full working order, and during the last few days of the meet there was a continual fight for the distance and duration records between Latham of the Antoinette, Henry Farman of the Farman, and Paulhan of the Voisin. The Antoinette was much the fastest, but its engine always failed to hold out long enough to beat the others. However, the Antoinette proved in other respects to be the fastest flying-machine of the year. It was the first machine in which real care was taken to gain a correct stream-line form. The wings were king-post girders. The body was largely a box-girder composed of three-ply wood. The tail was separated from the rest of the plane by uncovered longerons. Unfortunately, the internal structure of later machines of this type was weak, so that there were many fatal results from breaking in the air. The control was also very hard to learn. One wheel worked the warping of the wings, another worked the elevator, and there was a rudder-bar for the feet. In spite of this the plane was very beautiful to look at. THE 1910 BREGUET The first successful machine of this type was designed by M. Breguet, a French engineer, who had begun experimenting in 1908, and it appeared the latter part of 1910. The first of the year he produced a machine which was nicknamed the “coffee-pot,” because it was enclosed entirely in aluminum. This was developed later into a bombing-machine which had many interesting features. It was almost entirely constructed of steel tubes covered with aluminum plates, which led some to call it an armored aeroplane, which it was not. The tail, which was one piece with the rudder, was carried on a huge universal joint at the tip of the body, so that it swivelled up or down or sideways in response to the controls. The wings had one huge steel tubular spar, and as a result only one row of interplane struts. The under-carriage had a shock-absorber of a pneumatic-spring construction, which was highly satisfactory, and was the prototype of the elastic-rubber devices. The machine was heavy, but it was fast and a great weight-carrier. Because of minor defects in detail the machine never was generally used, but it was the first step toward the big tractor biplane of to-day. The Breguet 1913 seaplane, equipped with a Salmson engine, 200 horse-power, was one of the first to utilize large horse-power and was thus the forerunner of the huge flying-boat of to-day.
