KOREAN FLYING SAUCER!!! What Are They Building In There?

IF you go to Dutch Google Maps ( www.maps.nl ) and type Pyonyang North Korea you can zoom with the satellite map just north of the city and see the DEATH STAR flying saucer they have.
 Just follow the major highways north and zoom just north of the big X. X marks the spot... kind of.
crazy looking building

U.S.A. Google Maps won't let you ZOOM close enough to see this!
