The Atlantic Ocean Arc, that has been stationed on the Ocean floor for thousands of years, has risen up into the atmosphere above the center of the Atlantic Ocean, and is hovering there.
All the governments and all the militaries know it is there.
Signals have been transmitted between that arc and one of the arcs in Antarctica.
Signals have also been transmitted to and from a spacecraft that is described as 13 miles long, that is moving towards Earth.
