I think it is because no one has has the interest of going down there. These days it would cost a lot of money to even get to the spot alone, let alone down down into the ocean seven miles.

They have to have special equiptment to be able to get down there. They cannot just dive and get down to the bottom.

Its made of steel so it can handle all of the water pressure.
