After watching/reading/looking at information that has been done on the discovery of the so called Titanic at the bottom of the Atlantic Ocean, how do we know for certain that it was the Titanic? Speculation in 1912 and even today that the ship that may be at the bottom is her sister ship Olympic. The reason for this being the colliding of the olympic with the British warship the Sea Hawk in 1912, which did great damage to Olympics Hull and was seen too much to mend. On these submarine dives down to the Titanic, why hasnt a submarine looked for the name print on the sides of the ship above the anchors, or at the very stern of the ship where it should say "Titanic, Liverpool." Many dives have been taken place, yet besides the artifacts that have been recovered, why cant they find hard evidence by looking for the name on the hull? Is this the true secret to Titanic??
