Model balloons and flying machines

Scientific men now consider that mechanical flight is possible, and the person who experiments with flying machines is no longer looked on as a crack-brained enthusiast trying to discover the impossible. The successful flights, which are being carried out everywhere with heavier than air machines, are causing great attention to be devoted to the study of Aviation and Aeronautics. While inventors are busy, makers are vying with each other as to who shall construct the most successful flying machine. It is expensive to build a full-sized machine and carry out experiments with it, therefore unless the would-be aviator is wealthy, and at the same time is not unwilling to risk his life, he must content himself by experimenting with models.
