The Search for the Missing Titanic Submersible Continues.

A submersible carrying five people to explore the Titanic wreckage is still missing despite a massive search operation by US and Canadian authorities. The submersible lost contact with its support ship, leaving the people on board with only enough oxygen for 3 to 4 days. The depth of the area where they went missing could pose a challenge, and the search is complicated by its remote location, local weather conditions, and unknowns like the state of the submersible and whether it has working equipment like acoustic pingers that can be detected by search teams.
