Hauksbee 103 Posted August 22, 2013 Just received the following from my sister: a neverending source of fascinating internet snippets. It seems, that in the early days of Air Mail and passenger service, a series of visual directional cues were built across the country. I'd never heard of these, Great stuff! . JUST A LITTLE BIT OF HISTORY... Every so often, usually in the vast deserts of the American Southwest, a hiker or a backpacker will run across something puzzling: a large concrete arrow, as much as seventy feet in length, sitting in the middle of scrub-covered nowhere. What are these giant arrows? Some kind of surveying mark? Landing beacons for flying saucers? Earth’s turn signals? No, it's the Transcontinental Air Mail Route . On August 20, 1920, the United States opened its first coast-to-coast airmail delivery route, just 60 years after the Pony Express closed up shop. There were no good aviation charts in those days, so pilots had to eyeball their way across the country using landmarks. This meant that flying in bad weather was difficult, and night flying was just about impossible. The Postal Service solved the problem with the world’s first ground-based civilian navigation system: a series of lit beacons that would extend from New York to San Francisco . Every ten miles, pilots would pass a bright yellow concrete arrow. Each arrow would be surmounted by a 51-foot steel tower and lit by a million-candlepower rotating beacon. (A generator shed at the tail of each arrow powered the beacon.) Now mail could get from the Atlantic to the Pacific not in a matter of weeks, but in just 30 hours or so. Even the dumbest of air mail pilots, it seems, could follow a series of bright yellow arrows straight out of a Tex Avery cartoon. By 1924, just a year after Congress funded it, the line of giant concrete markers stretched from Rock Springs , Wyoming to Cleveland , Ohio . The next summer, it reached all the way to New York , and by 1929 it spanned the continent uninterrupted, the envy of postal systems worldwide. Radio and radar are, of course, infinitely less cool than a concrete Yellow Brick Road from sea to shining sea, but I think we all know how this story ends. New advances in communication and navigation technology made the big arrows obsolete, and the Commerce Department decommissioned the beacons in the 1940s. The steel towers were torn down and went to the war effort. But the hundreds of arrows remain. Their yellow paint is gone, their concrete cracks a little more with every winter frost, and no one crosses their path much, except for coyotes and tumbleweeds. But they’re still out there. .

+Erik 1,805 Posted August 22, 2013 Yes and if you have good coordinates of the arrows you can look them up in google maps. It's good stuff. Share this post Link to post Share on other sites
Stratos 3,188 Posted August 22, 2013 Thanks for sharing. Can you imagine doing that route once flying your own plane? I will love it for sure, one of my dreams!! Share this post Link to post Share on other sites
HumanDrone 4 Posted August 22, 2013 Thanks for sharing. Can you imagine doing that route once flying your own plane? I will love it for sure, one of my dreams!! I would too! I just took my son on his first airplane ride at a local airport. We flew over our house, etc - good stuff. And the "bug" bit me again. So I looked up about what it would cost to get a simple private pilot's license. And, at something on the order of $13 - $15K, I thought, "Stick to your Saitek X52, chum..." Yow! But thanks for sharing, that's pretty cool. Now if I ever come across one, I'll know what it is! Share this post Link to post Share on other sites
Wayfarer 5 Posted August 22, 2013 I have never heard of these before, but I love that such a system existed. If today had been April 1st I'm not sure I would have believed it. Share this post Link to post Share on other sites
