Oxygen supplies running out after vessel lost contact during ‘daredevil’ trip
Search teams and rescuers are racing against time to find a tourist submersible that went missing during a dive to the wreck of the Titanic.
Five people were on board the Titan when contact with the small sub was lost about an hour and 45 minutes into the dive on Sunday. The vessel has a 96-hour oxygen supply in “case of emergencies”, Sky News reported - leaving around two days of “life support” for the passengers.
What did the papers say?
The submersible went missing in the Atlantic, 435 miles south of Newfoundland in Canada, during a descent to the “iconic wreck”, which sits at a depth of 3,800 metres, said Toronto Star. The passengers “were aiming to be among the very small clique of those to have ever laid eyes on the Titanic” since the ship sank in 1912, the paper added.

What went wrong remains unclear, but experts have offered some “likely scenarios”, said The Guardian, ranging from “becoming tangled in wreckage of the Titanic” to a power failure or a problem with the sub’s communications system.
The missing passengers are widely reported to be British billionaire businessman and explorer Hamish Harding; Pakistani businessman Shahzada Dawood and his son, Suleman; French explorer Paul-Henry Nargeolet; and Stockton Rush, chief executive of OceanGate, the company that owns the missing sub.
The “pricey” and “daredevil” expedition is an eight-day experience arranged by OceanGate Expeditions that costs $250,000 a ticket, said the New York Post.
A New York-based writer who took a trip on the Titan sub last year said that “you all know what you are getting into” when you sign up.
Passengers “sign a massive waiver that lists one way after another that you could die on the trip”, Mike Reiss told BBC Breakfast. “They mention death three times on page one so it’s never far from your mind,” he added.
What next?
Officials have sent two C-130 Hercules aircraft to search for the submersible on the surface of the water, and an underwater sonar search is also under way.
The hunt is “complex” because crews do not know if the vessel has surfaced, said Rear Admiral John Mauger, first district commander of the US Coast Guard, who is overseeing the operation.
The Titan has drop weights, which can be released in an emergency, creating enough buoyancy to take it to the surface, where “an array of signals, lighting, reflectors and other equipment” can be used to attract attention, said The Guardian. However, experts told the paper that if there has been a leak in the pressure hull, “the prognosis not good”.
According to CNN meteorologists, the area is seeing “choppy seas” and foggy conditions, causing problems for search parties. And “depending where and at what depth” the sub might be found, there could be “limited options” for rescue vessels, said the site. US Navy submarines usually operate at 800ft or less, and might “implode” at lower depths due to water pressure.
But the Navy does have specialised rescue submersibles that can go to depths up to 2,000 feet.
The “daring rescue” would be “the deepest recovery mission in history” if crews are able to “pull it off” before the vessel runs out of oxygen, said the New York Post.
The disappearance is fuelling an “ongoing debate in scientific circles” about the “relative merit of manned submersibles”, because “each deployment incurs a safety risk”, wrote Stefan B. Williams, an expert on marine robotic systems, on The Conversation.
Joe MacInnis, a member of the first expedition to locate the wreck of the Titanic, in 1985, told The Guardian that “this is the day that we have been fearing for a long, long time – when you lose a sub in really deep water”.
CBS journalist David Pogue, who did the dive last year, told the BBC that it is not possible for those aboard the sub to escape without help, because they are sealed inside by several bolts applied from the outside. “There’s no backup, there’s no escape pod,” he said. “It’s get to the surface or die.”
