In the matter of international regulation of aircraft it is a great deal more important because of the ease with which commodities could be smuggled in from one country to another, even though mountains or rivers intervene at the borders. Flying at one hundred miles per hour, carrying two or three tons, smuggling could be carried on very extensively between different countries of the world. The aerial police and aerial navigation laws could restrain and stop such unlawful flying, but an international code is necessary to determine their rights. It is more important, however, to determine and prescribe the places at which foreign aircraft could cross the border or land for customs inspection. In these regulations should also be incorporated a code of international law. The conditions under which the fleet should pass from one country to another should be prescribed. Unless this was done it would be possible for any country in Europe, operating a fleet of 10,000 or more commercial aircraft, to convert them into bombers, each carrying tons of inextinguishable incendiary bombs, which could destroy a city like Paris, Brussels, or London within a few hours. A menace of this last possibility is so great that the leading aeronautical authorities in Paris and London have asked for a specified written code of aerial navigation laws, to be adopted by the League of Nations. In conformity to that object of controlling all kinds of aircraft, the British Aerial Transport Committee have drawn up a draft of a bill for the regulation of aerial navigation. The principles laid down in this bill are so universal in their application that they could be very well adopted by the United States and other nations of the earth. Prior to the war, as early as 1905, and forever afterward, the International Aeronautical Federation was organizing laws regulating aerial navigation, and making it the chief topic of discussion. In 1910 the International Convention held in Paris drew up aerial acts restricting navigation over forbidden zones. There was not at that time sufficient aircraft navigating to make these regulations as important as they are at the present time. Some of our own States passed some absurd laws to restrict aerial navigation to their own States. These were absurd because of the fact that no limits should be placed on the interstate flying to aircraft because most States in the Union could be flown over in a matter of hours. Federal laws only are sufficient to deal with this situation. The Department of Commerce, which has charge of both registration and inspection, is the logical department to have charge of the regulation of aircraft.
