During the opening period of the 1909 aëroplane season, Glenn H. Curtiss brought forth a new biplane, designed for the Aëronautic Society of New York, with the coöperation of his new partner, Mr. A. M. Herring, and began active practice for various prizes at home and abroad. After some brief trials at Hammondsport, N. Y., he shipped his aëroplane to Morris Park, in order to participate in the Aëronautic Society’s first flight exhibition of the year. On June 26th he flew, but without official witness, far enough to win one of the $250 prizes offered to the Aëro Club of America by its president, Mr. Cortlandt Field Bishop, for the first four persons who should fly one kilometer. He now wished to make an official flight for this prize and also for the Scientific American trophy, a beautiful engraved silver cup—which he had won a year previously for the first public flight of one kilometer, made in America, but which now should go to the person making the longest official flight of the year 1909, not under 25 kilometers. But the Morris Park race track proved unsuitable for such contest, being too restricted. He therefore took his biplane to Mineola, Long Island, where he could practice on a wide plain, and possibly make some new records. Here a triangular course 1.3 miles long was staked off, and some short trial flights were made. Then Mr. C. M. Manly, who was official timekeeper for the Aëro Club of America, was notified that a trial for the prize would be made. The demonstrations near Mineola were most successful, and proved the beginning of a brilliant summer for Mr. Curtiss. On July 17th he won in quick succession both of the prizes mentioned above. The trial for the smaller prize began at 5.15 in the morning and lasted but 2½ minutes, followed 6 minutes later by the start for the coveted cup. In both cases the machine took the air with ease and grace, after a 200-foot run over the rough marsh land. In the cup trial the first twelve turns, aggregating 25 kilometers, were accomplished in 33½ minutes, but the machine continued for seven more rounds, and finally landed in excellent form, just 52½ minutes after it had crossed the starting line. The actual measured distance flown was 24.7 miles, but the true distance traversed by the machine was probably 30 miles, making the time speed between 30 and 40 miles per hour. This was slow, indeed, but the control was satisfactory. Those who wished for high speed would find it in the new aëroplane which Mr. Curtiss would presently take to Rheims for the speed contest, in which he was to fly as sole champion of the United States.
