The Endless Fascination with the Titanic Wreck: Search, Rescue, and Recovery.

The rescue mission to save five people in a submersible lost in the Atlantic is facing a tough choice as the window of opportunity closes. The pilot and four-person crew are believed to have less than 24 hours of oxygen remaining, and no one knows if the vessel is on the water’s surface, on the seafloor or somewhere in between. Experts say it is highly unlikely a vessel could be pulled to the surface from such a great depth without significant resources having been staged in advance. The company that owns the submersible, OceanGate, must make a call on what kind of salvage and recovery operation it wants to pursue at its own expense.
