* Beacon Tower System Airmail beacon tower designĪircraft of the era lacked the advanced electronics for navigation during night flights or through inclement weather. On August 20th, 1920 – sixty years after the Pony Express – rapid delivery made a return to the U.S. Two years later, a North American transcontinental airmail route was finally established. In July of 1914, French pilot Maurice Guillaux carried Australian mail 584 miles from Melbourne to Sydney – at the time the longest such flight in the world.īy 1918 the east coast of the United States had limited airmail service. It wasn’t until three years later the range capability of mail delivery aircraft was really tested. His pilot, Henri Pequet, would fly just over 8 miles from Allahabad to Naini to deliver 6,500 letters. Windham used the event to generate publicity and raise money for charity. The next day, a large exhibition orchestrated by Sir Walter George Windham in British India made the first official airmail flight. The Wright brothers made the first flight in 1903, and it wasn’t long before pilots adopted air transport for mail delivery.īy 1911, Fred Wiseman had conducted an unofficial airmail flight carrying three letters from Petaluma to Santa Rosa, California. * Early Aviation & Airmail vintage airmail advertisement Intermediate Field with tower in Nebraska It was not until the invention of the airplane that intercontinental mail delivery witnessed its next major breakthrough. In the late 19th century, reliability of mail delivery improved – but not its speed. When the transcontinental telegraph line was completed in 1861, it immediately rendered the Pony Express obsolete. Higher costs and poor economies of scale would see the Pony Express fail to win the mail contract beyond its first year of operation.Ī year later, the threat of civil war descended upon the country and resources were diverted to the conflict. Knowledgeable frontiersmen would race across the country on horseback, covering vast distances in shorter times. While the Pony Express was significant in that it proved the northern/central mail route was possible, it was inefficient compared to stagecoach lines. Nearly unheard-of at the time, this was faster than the more volatile southern route favored by others. Airmail beacon in Omaha, Nebraska (circa 1920s)īy 1860, the Pony Express revolutionized transcontinental mail by offering delivery in about ten days. The trip across the country was arduous, dangerous, and could take anywhere from three to six weeks. Understandably, coast-to-coast message delivery was nonexistent. It was not until a gold discovery in 1848 that California became the destination for tens of thousands from the east. There was no infrastructure and very little law governing the land. In the mid-19th century the Wild West was largely unexplored. * Early Airmail Beacon Route Map circa 1924. When radar and radio communications made the beacons obsolete years later, most were torn down or abandoned. Before long, a system of beacons was established across the United States to guide airmail pilots around-the-clock. This solution worked for flight during the day, but grounded pilots at night. In a era before radar, pilots used ground-based landmarks for guidance. The purpose was important: helping early pilots navigate U.S. The shape and direction of the arrows vary, but it is clear they served the same purpose. Many are in good condition while others have succumbed to nature. Some will be accompanied by a small shack, a few have a metal tower affixed to their base. They are often found in remote locations or areas difficult to access. Our services for ANSPs are backed by 24-hour, seven day-per-week, year-round support for mission-critical operations, with robust networking technologies and monitoring services to deliver reliable and available IT systems and global business continuity.Scattered across the United States are a network of mysterious concrete arrows. They ensure ANSPs can manage their airspace safely, efficiently and reliably, enabling clear data and voice exchanges with aircraft and airports. Our ANSP solutions offer a range of options to automate and ease the processes involved, integrating into existing environments and catering for multiple demands, whatever the platform. With a wide range of digital communications technologies, we enable seamless air-ground data and voice exchanges for ANSPs, for mission-critical weather information and operational messages at airports and to aircraft inflight. For decades, SITA has provided the air-ground communications network and systems that support the aviation industry, in every corner of the globe. Wherever they may be in the world, Air Navigation Service Providers (ANSPs) must ensure the safe and efficient passage of aircraft in their airspaces.
