Associated Press: Search for the missing Titanic submersible passes the critical 96-hour mark for oxygen supply
By Associated Press / June 22, 2023The search for the missing submersible on an expedition to view the wreckage of the Titanic passed the critical 96-hour mark Thursday when breathable air could have run out, a grim moment in the intense effort to save the five people aboard. The Titan submersible was estimated to have about a four-day supply of breathable air when it launched Sunday morning in the North Atlantic — but experts have emphasized that was an imprecise approximation to begin with and could be extended if passengers have taken measures to conserve breathable air. And it’s not known if they survived since the sub’s disappearance.
