This is China. Coordinates 40.458779.93.313129 Interesting airplane.
Assuming that the rays diverging from the center are runways, which is not certain - their length is small - only 124 meters - it is obvious that the site for light-engine aircraft is still short ... And do not find that .. some strange platform.
Also an interesting drawing in China-Coordinate 40.458181.93.388681 A snapshot from a height of 7 kilometers. I wonder what technologies it was possible to do.
Look at the dimensions.
It is interesting that there are two "runways" nearby. And when did they act, before the tectonic activity?
This is clearly abandoned and the impression is that 500 years ago.
On the second - there is no airport building and the planes themselves.
Maybe this is something military "wise", because next to it there is something like a runway with some sort of shelter or hangar.
But curiously, at a distance of 18 kilometers, there is another intricate pattern.
Picture from a height of 5 kilometers Coordinates 40.451323,93.743248
he length of this drawing is 1.8 kilometers
And what is this done on the surface of the earth?
The world does not cease to amaze.
To be continued.
