Hunt for missing Titanic sub continues

The US Coast Guard Wednesday diverted its robotic undersea search operations to the area where sounds, likely from the missing OceanGate Expeditions submersible, originated from. Search teams, as reported by the Coast Guard, detected underwater sounds as they scanned the North Atlantic to search for the tourist's vessel. The US Coast Guard tweeted that there was still no tangible sign of the missing Titan submersible.
