What's the purpose of the mammoth designs painted onto the floor of a Chinese desert?(40°27'4.87"N, 93°44'42.90"E) (see it in Google Maps). Perhaps only the Chinese military knows. That's who some people speculate is behind not several (40°27'23.66"N, 93°23'7.78"E) similar mile-wide paintings. A nearby Stonehenge-looking formation (40°27'31.04"N, 93°18'47.21"E) (see it in Google Maps) with three jets parked in the middle suggests a possible military purpose to the enterprise. But giant white lines etched into the Earth are not unique to just China. A mysterious pattern of white lines found in Norwich, UK (52.481725, 0.520627) (see it on Google Maps) has prompted some Fox Mulder fans to say "I want to believe."
