The model aeroplane has one great advantage over the man-carrying machines. It makes possible indoor aviation, and may be enjoyed the year round, and is especially effective for evening entertainment. The fortnightly meets in one of the great New York armories, some time since, attracted the attention of the officers, and the boys were invited to give exhibition flights in connection with athletic games. The first of these meets was held under the auspices of the New York Model Aero Club, in connection with the Greek athletic games, in the interval between the games and the ball which followed. An audience of fully 3,000 people, crowding the armory, witnessed the flights. Some twenty members of the club entered the contest. In a public contest of this kind, much depends upon the system of flying. The floor must be kept clear and the flights follow one another so quickly that the interest will not lag for a moment, and the audience have no opportunity to tire. The flights on this occasion went with a rush and proved in every way so successful that the rules which made this program are given in full on another page. Few in the audience had ever seen a model flight, and the contest held the great crowd’s attention more closely than had any of the evening’s athletic events, which had come before. There was a breathless moment of suspense when the whistle had sounded for the first flight. A beautiful white monoplane led off, but in the excitement of the moment, it had not been properly adjusted, and failing to get its altitude, spun daintily across the floor. The second model yawed sharply and flew into the crowd at the side. The third model found itself, however, rose perhaps twenty feet and, settling down to a steady horizontal, darted across the arena. Every eye followed it. A burst of handclapping greeted its graceful rise, which increased in volume, and as it reached the farthest corner of the great armory, more than 200 feet distant, there was a perfectly spontaneous cheer. The program was so well organized and carried on that the flights followed rapidly without a break. There was scarcely a moment when an aeroplane was not aloft, and the interest never faltered. There were Scores of excellent straight-away flights of 200 feet or more, at various altitudes. Occasionally a model would fly wild, even refuse to rise, but the flights followed one another so continuously that a failure was quickly forgotten in the delight of watching the next flight.
