On June 19, 2011, at approximately 285 feet below the surface of the Botnia Gulf, a team of treasure hunters, known as Ocean Explorer, discovered what appears to be a 60-foot disc. In addition, there looks to be a 985-foot impact trail leading to the location of the disc. Peter Lindberg, the leader of Ocean Explorer, said, “You see a lot of weird stuff in this job, but during my 18 years as a professional I have never seen anything like this. The shape is completely round…a circle.â€

The sonar image of the disc and the trail leading towards it.
Ocean Explorer is not a group of individuals who search for UFO remnants – they are treasure hunters. In 1997, they found the sunken ship Jönköping, which was loaded with roughly 2,500 bottles of champagne. Each bottle was sold for $13,000. Obviously, Ocean Explorer is in the treasure hunting business to make money, not find potential crashed alien sites.
But the question remains: what is this thing?
If this was a manmade object, one can easily guess that the creator would have tried to retrieve it, especially if it was a government creation. If it was an individual project, without government funding, it also seems strange that one would blow enough money to create the 60-foot disc object, but not enough to retrieve the object. This easily leads one to believe that the object does not come from this world, like it is something from a Predator movie.
Peter Lindberg is not spending the money to retrieve the object, because he believes it would be nothing more than a “new Stonehenge†– not worth the money to retrieve it. As an alien buff, I can only hope that some other entrepreneur comes forward to surface this strange 60-foot disc.

Clearly it’s the Millennium Falcon. Looks like Han Solo zigged when he should have zagged.
Its could be this russian ship called Novgorod built in 1847
