Search for Missing Titanic Submarine Intensifies with Undersea Noises Detected

The search for the missing submersible that was exploring the wreckage site of the Titanic continues, with crews detecting underwater noises in the search area. More information has emerged about experts' attempts to warn OceanGate, the company that owns the submersible, about the perils of its operations. Documents show an OceanGate employee warned there might be safety problems posed by the way the experimental vessel was developed, and leaders in the submersible craft industry told the company its approach to the enterprise could have a "catastrophic'' outcome. The submersible may have only a day's supply of oxygen left.
