There is hundreds of millions to be made by finding underwater treasures – gold buried at the bottom of the sea for centuries onboard sunken ships. Recently an American company made what archeologists believe is the world’s biggest treasure find, but huge controversy surrounds the find and ownership of the treasure. The Spanish authorities suspect the treasure has been fished out of its waters. The American company refuses to reveal the location, despite its ship being docked in Gibraltar for many months. The haul was half a million silver and gold coins valued at €400 million. The booty was flown from Gibraltar to Tampa, Florida on a plane charted by Odyssey – the American company. It promises to start a legal tug-of-war between the company and Spain over who really owns the treasure. But the airlift is just Odyssey’s latest foray along the Spanish coast. The company has operated two vessels and a high-tech robot submarine over the last nine years, often without marine archeology permits.
