This is kind of mind blowing. A large disk on the ocean floor has been moving and creating a trail behind it. This is directly from the Google Earth map. The UFO measures 2.6 miles across according to Google ruler. Understand the trail you see is only part of it. There is still hundreds of miles of trail around it that it also created. Awesome discovery by Securityteam10 of Youtube.
