HERE IS THE "Baltic Sea UFO". I was discovered by Sonar, sitting on the bottom of the Baltic Sea off Sweden, a few years ago. It is about 160 meters in diameter. It appears to symmetrical and has patterns in it to be a simple rock. Besides, when people are on the water above it or near to it, watches stop and Satellite phones no longer work. More dives and investigation will be conducted on this one in the near future this summer.
