Naturally no manufacturing industry can exist without a potential market. Aircraft manufacturers are sure the majority of the twenty thousand flyers and hundred thousand aero mechanics who have learned their trade in the Great War will want to fly either machines of their own or of somebody else or of some transaerial company. The aeronautical engineers have, therefore, designed the sports type for the young fellows who wish to race in the air, travel from country town to country town, from lake to river, or to commute from country to city. Since these machines fly faster than the fastest bird or the fleetest animal, they will afford great sport for gunners. Indeed, the machines have already been used with such disastrous effects upon the bird that many hunters say it is not good sportsmanship to hunt from them. In that case, perhaps, the farmers will hire the daring young aviators to hunt down the crows and hawks with these dragons of the air. Be that as it may, this sports type is a great convenience for a person who works in a city located on a large lake or on a river and who wishes to live far in the country. Indeed, he may live a hundred miles up or down that body of water and in less than an hour he can fly to or from his work. If it is cold he can put on his electrically heated clothing and keep as warm as in a limousine. If he has engine trouble he can land anywhere and fix his machine and then fly on. Since air resistance is much less than road resistance he can traverse the distance much cheaper than in an inexpensive automobile. If there is no body of water near his place of business he can land his cross-country flier in the park or flying-field just as easily as on the water. This same machine will lend itself to all kinds of pleasure flying, and no other sport gives so much exhilaration, scenic view, and adventuresome excitement as the aeroplane; and the price will be within the means of many young men.
