Concrete Arrows and the U.S. Airmail Beacon System

airmail-beacon-concrete-arrow-cover

Scattered across the United States are a network of mysterious concrete arrows. They are often found in remote locations or areas difficult to access. Some will be accompanied by a small shack, a few have a metal tower affixed to their base. Many are in good condition while others have succumbed to nature. The shape and direction of the arrows vary, but it is clear they served the same purpose.

The purpose was important: helping early pilots navigate U.S. transcontinental flights at night.

In a era before radar, pilots used ground-based landmarks for guidance. This solution worked for flight during the day, but grounded pilots at night. Before long, a system of beacons was established across the United States to guide airmail pilots around-the-clock. When radar and radio communications made the beacons obsolete years later, most were torn down or abandoned.

History

In the mid-19th century the Wild West was largely unexplored. There was no infrastructure and very little law governing the land. 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. The trip across the country was arduous, dangerous, and could take anywhere from three to six weeks.

By 1860, the Pony Express revolutionized transcontinental mail by offering delivery in about ten days. Nearly unheard-of at the time, this was faster than the more volatile southern route favored by others.

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. Higher costs and poor economies of scale would see the Pony Express fail to win the mail contract beyond its first year of operation.

A year later, the threat of civil war descended upon the country and resources were diverted to the conflict. When the transcontinental telegraph line was completed in 1861, it immediately rendered the Pony Express obsolete.

In the late 19th century, reliability of mail delivery improved – but not its speed. It was not until the invention of the airplane that intercontinental mail delivery witnessed its next major breakthrough.

Early Aviation & Airmail

The Wright brothers made the first flight in 1903, and it wasn’t long before pilots adopted air transport for mail delivery.

By 1911, Fred Wiseman had conducted an unofficial airmail flight carrying three letters from Petaluma to Santa Rosa, California.

The next day, a large exhibition orchestrated by Sir Walter George Windham in British India made the first official airmail flight. Windham used the event to generate publicity and raise money for charity. His pilot, Henri Pequet, would fly just over 8 miles from Allahabad to Naini to deliver 6,500 letters.

It wasn’t until three years later the range capability of mail delivery aircraft was really tested. 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.

By 1918 the east coast of the United States had limited airmail service. Two years later, a North American transcontinental airmail route was finally established. On August 20th, 1920 – sixty years after the Pony Express – rapid delivery made a return to the U.S.

Beacon Tower System

Aircraft of the era lacked the advanced electronics for navigation during night flights or through inclement weather. Long before the advent of radio guidance or Instrument Flight Rules (IFR), pilots were limited to visual guidance, using landmarks to chart the route.

Flying at night was out of the question; bad weather and limited flight times meant delivery was limited and still spotty in frequency. The service was indeed faster, but it lacked flexibility and reliability of operations.

By 1924 the Postal Service developed a solution that was effective, if not elegant.

http://sometimes-interesting.com/2013/12/04/concrete-arrows-and-the-u-s-airmail-beacon-system/A system of ground-based navigation beacons extending from New York to San Francisco would help pilots fly across the country at night and ultimately be the world’s first such system.

The early iterations of the system used approximately 1,500 airmail beacons, each constructed roughly between 3 and 5 miles apart. The beacons featured a 50-foot tower with rotating lights placed on top of concrete foundations in the shape of giant arrows measuring between 50 and 70 feet long. To increase visibility of the concrete arrows, they were painted bright yellow.

The first towers contained acetylene-gas powered lights which were fed by fuel stored in a shed at the base. At the top of the towers, a rotating beacon with 5,000 candlepower and would flash every ten seconds.

http://sometimes-interesting.com/2013/12/04/concrete-arrows-and-the-u-s-airmail-beacon-system/In clear weather the beacon lights could be seen for 10 miles (16 km). Below the main white beacon, a secondary set of red and green lights would flash a Morse Code letter to identify the beacon to pilots.

To accommodate for emergencies, intermediate landing fields were established every 25 miles along the route. The fields were constructed with rotating incandescent electric lights mounted on 50-foot towers set to sweep six times per minute. These less-common emergency field beacons were visible up to 75 miles away.

The program was an immediate success and continued to expand throughout its operational life. By the end of the first year the airmail service had 18 terminal airfields, 89 emergency airfields, and more than 500 beacon lights in operation.

Rapid Growth Until Obsolete

http://sometimes-interesting.com/2013/12/04/concrete-arrows-and-the-u-s-airmail-beacon-system/In 1926 management of the beacon system was turned over to the Department of Commerce, which continued expansion or the airmail beacon system until 1929.

As technology improved, so did the towers. Later versions on spur routes were built 10 miles apart and equipped with stronger beacon lights – up to one million candlepower – making them reportedly visible up to 40 miles in clear weather.

But by the 1930s, navigation and radio technology had improved to allow flight without land-based visual guidance. The Low Frequency Radio Range (LFRR) system began to replace older visual-based systems. The airmail beacon program would continue to operate full-scale until 1933, when technology advancements and the higher cost of operation during the Great Depression – finally rendered it obsolete.

After the program was de-funded, various beacons would continue to operate in limited capacities into the 1940s. At that time, the Department of Commerce decommissioned and disassembled the towers for their steel, a resource in short supply and desperately needed to support the war effort.

The last airway beacon was officially shut down in 1973, although the Montana Department of Transportation Aeronautics Division reportedly continues to operate around 19 updated beacons in the mountains of Western Montana.

Today

Ninety years later, most of the towers have been dismantled. Many of the sites are long gone, victims of war, infrastructure growth, and aggressive private developers. During World War II, numerous concrete arrows were destroyed as well – so as to not help enemy pilots visually navigate the country.

Still, hundreds of the arrows remain. But today they lack the bright yellow paint, and the cracks in the concrete worsen with each winter freeze. Arrows on top of mountains are safe for now, but several along the highways have already been lost to redevelopment.

Thanks to S-I readers Denver Alt, Darwin milkman, Jesse Finney, and Aaron Stephenson, who made the trek out to the Underwood beacon in June of 2017 and sent us the photos below. Denver says “The tower is still climbable and the decking is intact… The pad for the generator station has been broken up, and there is no longer evidence of the arrow.  It looks like they broke up the pad with a sledge and let nature take its course…  Interestingly, we found the remains of several light bulbs.  It seems to reason that the guy why climbed up there to change them just chucked the old ones off the top… Tower measures 50′ and has 39 rungs of ladder to the top that each has 15” of spacing between them.

• In the wilderness outside of Cheyenne, Wyoming, the remote concrete arrow of Beacon 38 sits undisturbed (pictured below, courtesy S-I reader John Breeding).

John shared his encounter with Beacon 38: The concrete is still in amazing shape… the ‘concrete’ is basically quartz pebbles held together with cement…that arrow is going to be there for centuries if no one messes with it.  The tower supports were cut off at ground level and what appears to be the fuel oil shed foundation seems to have been broken up but is still visible. One other interesting point of note is the barren ground in the shape of the arrow just a foot or so off the edge of the concrete.  My guess is they ‘salted’ the ground there to enhance the arrow shape from the air.  Decades later there’s still nothing growing there.” Before you consider visiting, John notes this may be on private property.
