Germany, throughout what was for her a terrible year, made further progress with her Zeppelin dirigibles. A number of return voyages were made over the route Berlin-Munich-Vienna-Constantinople. The latest type of Zeppelin is so efficient that no weather conditions, except a strong cross-hangar wind, prevents the airship _Bodensee_ from making its daily flight of three hundred and ninety miles between Friedrichshafen and Staalsen, thirteen miles from Berlin. The passenger carrying Zeppelins, which prior to the war provided the only important example of commercial aircraft, claim a remarkable record. They have carried more than one hundred and forty thousand people, and yet not one of the passengers has been killed or injured in an accident; although some members of the crews lost their lives in the early days of the pioneer Zeppelins. The vast distances of the United States offer better opportunities for aëroplane traffic than the comparatively small and closely-railwayed countries of Western Europe. There is no doubt that, had the United States government supported its aircraft companies to the same extent as did the British government, commercial aviation in America would have traveled along a smooth road. Even without this support it has made excellent progress. Successful regular services are established between Los Angeles and San Diego, and elsewhere in the West, and in the East many passengers have been carried between New York and Atlantic City, and around the coast of Florida. Plans are being laid for various other airways, including one between Key West and Havana. While no continuous service for aërial goods traffic exist in the United States, aëroplanes are often chartered for special deliveries. This is particularly the case in the oil countries of Texas and Oklahoma, where newly-grown and important centers are off the beaten railroad track. One company in Oklahoma regularly sends its employees' pay by aëroplane from town to oilfield camp, thus assuring a quick and safe delivery, free from the necessity of armed guards and the danger of hold-ups. Other items worth noting in the United States' aërial history of the past twelve months are that aëroplanes have performed survey work and located forest fires, that thirty-two cities have applied for commercial aërodromes for postal, passenger and express purposes, and that an advertising agency is soliciting aërial business that will include display work on dirigibles, balloons and aëroplanes, the dropping of pamphlets from the air, and aërial photography.
