Search for Missing Titanic Sub Continues with Coast Guard Update and Starlink's Help.

A search and rescue operation is underway in the North Atlantic after a submersible exploring the wreck of the Titanic went missing on Sunday. The Titan submersible, carrying five people, lost contact with the surface one hour and 45 minutes into its descent. The US Coast Guard estimated the sub had 40 hours of emergency oxygen left, as of about 13:00 EST (18:00 BST) on Tuesday. The search has involved US and Canadian forces, private vessels, and remote-controlled submersibles, with a commercial pipe-laying ship and specialised US Navy remote submersibles expected to join.
