Very strange, and if you looked at all 10 pictures, one grid is 18 miles long, perfect lines and grid on rough terrain. In the round picture 3 aircraft are in the center, assuming these black blocks or buildings the planes appear landlocked in the center, with no convienient path to move them outward. What is the purpose of that? Tagrets, maintinance, who knows. Could be all targets for them to test from space. How to map others moons or planets? Military homing test grids, to prefect pinpoint accuracy of cruise missiles in complex cities? The Chinese are very aggressive in their Space programs right now, plus continue to build the threat of global warfare. The Olympics were a message to the world the level of things they can achieve and build, using their people as tools. All this high tech technology, plus the size of the army they can make, watch out!
