Light on a Titanic mystery -- but where's the hull?

Explorers said they solved the mystery of why the Titanic went down in the Atlantic Ocean's icy waters 69 years ago, but they declined to say if they had located the ship's remains.

"We searched the Titanic area and believe we know what did happen. We feel we've solved the mystery," leader Mike Harris said.

Oilman Jack Grimm, who financed the mission, said the team had not found the main body of the Titanic, but had "very interesting" photographs. Some photos helped determine why the ship sank, Mr. Harris said. Further inform ation will be given when the research ship returns to port.
