Please read link below, it is the laws re; salvaging of ships that is why a US court was able to make a decision, international waters plays a big part.. These are international laws. By the way, the USA does not own the Titanic a private US company claimed salvage rights called Titanic Inc. That is why the claim was filed in a US court. Harland & Wolff - Belfast, Ireland....They were paid to built it they did not own it and I visited those old shipyards, that entire shipyard is long since gone before the Titanic was discovered.
White Star Line - Owned the Titanic-But White Star went out of business when Titanics sister the Britanic sunk as a hospital ship in less time then the Titanic with modification that caused the sinking of the Titanic, so White Star was no longer in existence when the Titanic was found.
International Mercantile Marine - owned White Star Line, JP Morgan was the President. Well also know as the IMM. They never actually owned a piece of the liner. IMM was a holding company that controlled subsidiary corporations that had their own subsidiaries. Morgan hoped to dominate transatlantic shipping through interlocking directorates and contractual arrangements with the railroads, but that proved impossible because of the nature of sea transport, American antitrust legislation, and an agreement with the British government. One of IMM's subsidiaries was the White Star Line, which owned the "Titanic." That ship's famous sinking in 1912, the year before Morgan's death, was a financial disaster for IMM, which was forced to apply for bankruptcy protection in 1915. Analysis of financial records shows that IMM was overleveraged and suffered from inadequate cash flow that caused it to default on bond interest payments.
No one seems to know the only company who is still hear today that could of but did not take possecion of the Titanic becuase under salvage laws they could and that is Lloyds of London the Insurance Company who insured the entire ship and all things aboard. But long before the ship was found and before the Technology was their to find it, Lloyds gave up there right and wrote off the entire ship think it would never be found and too deep to salvage. When wrote off the ship as a total loss there were no more owners left. So When Robert Ballard found it. He made the big mistake of sharing the coordinates with idiots because as he put it personally, he made a mistake of having faith in people. Which is why all the ships he fond since he makes everyone sign confidentiality agreements. So like he found the Bismark, if anyone gave out those coordinates they could go to jail. Yes, I the reason why I know this is I met Robert Ballard at a speaking engagement at University of Hawaii at Manoa's Distinguished Lecture Series. Dr. Ballard presented a free public lecture on Friday, February 9, 2001 our the our main conversation is why Lloyds of London never claimed the wreck. You can see the engagement where we spoke below. Ronald Reagan tried to put a stop at Ballards request to declare it a historical grave site, but congress never passed the law. So now the grave of over 1500 soles is being stripped for profit. Commander Ballard (he still holds the rank of a navel commander)
could of claimed the wreck and to this day is sorry he did not. But has claimed every wreck he has found since.
I am also a wreck diver, deap sea, nitrox, helium, and re-breather certified. There are over 1500 wrecks around shallow waters in US seas off Florida, the Keys, southern east coast, Texas, and the gulf states.
But the companies who owned the Titanic were long gone by the time she was found and the insruance compnay who owned her who is still around. Wrote her off a long time ago, not foreseeing in the future the technology to find her. So when Ballard did not claim her, it left the door open for the next guy, it is that simple. Under international salvage laws it was perfectly legal.
