What Are the Giant Barcode-like Symbols Seen in the Skies of the USA?

America you know whose name is most associated with aliens country. That’s why any extraordinary event that happens there can immediately bring aliens to our minds.

Actually, we are not wrong to think so, after all. restricted areas such as Area 51 America, which is America, can naturally scare many people. But don’t worry, these giant symbols are not about that.

The origin of these strange symbols, until the Cold War going. “So what do these symbols have to do with the Cold War?” Don’t say that because America has prepared itself for all kinds of situations.

Although they look like ruins of an ancient civilization when viewed from above, the main purpose of these symbols was to strengthen the United States’ aerial reconnaissance technology.

In the 1950s and 60s when there was Cold War tension for lens calibration These symbols were generally created using thick black or white paint on smooth concrete or asphalt.

Smaller than a basketball court, these symbols are visible on the imaging equipment of aircraft and satellites. optical resolution It was used for testing.

This situation, which seems incredibly logical when we look at the past, is especially true of the most difficult aircraft developed. (like SR-71 Blackbird and U-2) It worked pretty well during testing.

Moving at different speeds and altitudes for aerial photography testing aerial cameras, These symbols for calibrating and focusing were an essential part of the technology of those days.

These giant symbols are no longer functional in today’s technology, but they still exist.

Especially at the air bases of the states The existing symbols became dysfunctional with the transition to satellite-based surveillance. It is not known why America does not eliminate these structures, but in case a possible war breaks out in the past, how much you prepared yourself One of the most important indicators.

These mysterious events in America are not the first, we have previously made a content explaining what the giant arrows are used for:

Both these structures and giant concrete arrows Imagine the area it covers in America. What an unnecessary waste of space, right? Anyway, the research also turned into a topic for the content of social media theorists who like to scare people. 🙂
