Circular object:  Sonar readings show that the mysterious object is
about 60 meters across, or, about the size of a jumbo jet. And it's
not alone. Nearby on the sea floor is another, smaller object with a
similar shape. Even more fascinating, both objects have "drag marks"
behind them on the sea floor, stretching back more than 400 feet.
