80-year-old concrete arrows extending from NY to SF helped deliver mail in 1920s


quote:





Travel in a straight line between New York and San Francisco and you might find a strange set of concrete arrows on the ground. The arrows — set into anonymous hillsides and nondescript scrubland — were laid down by the US Postal Service in the 1920s. Prior to the invention of radar and other modern flight planning implements, pilots would have difficulty navigating the coast-to-coast route over the American midwest: the arrows, when combined with a fifty foot tower and a powerful gas light, would help them find their way.

America's first transcontinental air postal route was opened on August 20th, 1920. The first pilots to fly the route had to rely on landmarks to guide their way across the land, making the journey near-impossible in poor visibility. To make the route navigable in the rain or the dark, Congress approved funding for a network of beacons in 1923. The first beacons were built in 1924, and covered a portion of the flight from Ohio to Wyoming. By 1929, the network stretched from New York to San Francisco. Rotating beacons lit arrows painted in bright yellow to guide travelers, and any pilots who did run into trouble with their flimsy biplanes knew that emergency airfields were located close to the markers.

Yep. That is why I have so much free time now to post obscure crop circle threads in the middle of the night.

Btw, this is me walking off the field after my last game on Saturday.

That's GPS for aliens.

(ETA: Galactic Positioning System, for clarification)

Not 80 is also an acceptable answer

What if you were flying from SF to NY?

The arrows are facing the wrong way!

That is possibly an even more obscure reference.
