BOSTON, June 22 (NNN-AGENCIES) – A massive search and rescue effort for a missing submersible near the wreck of the Titanic entered a critical stage late Wednesday, with just one night left before the oxygen supply for the five people on board runs out.
While coast guard officials insisted they remained “hopeful,” with a surge of assets and experts joining the operation and sonar picking up unidentified underwater noises, the challenge of locating and recovering the crew alive appeared increasingly formidable.
“Sometimes you’re in a position where you have to make a tough decision. We’re not there yet,” said US Coast Guard Captain Jamie Frederick, adding that it remained a search-and-rescue mission “100 percent.”
Organizers of the multinational response — which includes US and Canadian military planes, coast guard ships, and teleguided robots — are focusing their efforts in the North Atlantic close to multiple “underwater noises” detected by sonar late Tuesday and Wednesday.
The sounds raised hopes that the passengers on the small tourist craft are still alive though experts have not been able to confirm their source.
“We don’t know what they are, to be frank with you,” said Frederick, who added: “We have to remain optimistic and hopeful.”
Titan began its descent at 8 am on Sunday and had been due to resurface seven hours later, according to the US Coast Guard.
Rescuers, who have received help from around the world, estimate that passengers may run out of oxygen on Thursday morning, based on the sub’s capacity to hold up to 96 hours of emergency air.
The 6.5-meter tourist craft lost communication with its mothership less than two hours into its trip to see the remains of the Titanic, which sits more than four kilometers below the surface of the North Atlantic.
The submersible, named Titan, was carrying British billionaire Hamish Harding and Pakistani tycoon Shahzada Dawood and his son Suleman, who also have British citizenship.
OceanGate Expeditions charges $250,000 for a seat on the sub.
Also on board is the company’s CEO, Stockton Rush, and a French submarine operator Paul-Henri Nargeolet, nicknamed “Mr Titanic” for his frequent dives at the site.
Ships and planes have scoured around 20,000 square kilometers of surface water for the vessel, which was attempting to dive about 400 miles off the coast of Newfoundland, Canada.
After the noises were detected by a Canadian P-3 aircraft, rescuers relocated two remotely operated vehicles (ROV) that search under the water and one surface vessel with sonar capability.
The ROV searches have not yielded results but data from the Canadian aircraft has been shared with US Navy experts for acoustics analysis.
“There have been multiple reports of noises and every one of those noises is being analyzed,” said Carl Hartsfield, from the Woods Hole Oceanographic Institution.
He added that the sounds “have been described as banging noises.”
Frederick said the number of surface vessels in the search would double from five to 10 within 24 to 48 hours.
The Navy has sent a specialized winch system for lifting heavy objects from extreme depths, other equipment and personnel; and the Pentagon has deployed three C-130 aircraft and three C-17s.
A deep-sea underwater robot sent by France’s oceanographic institute was due to arrive early Wednesday afternoon.
Titan’s mission was expected to be the only manned trip to the Titanic this year due to bad weather, Harding wrote in on Instagram beforehand.
The Titanic hit an iceberg and sank in 1912 during its maiden voyage from England to New York with 2,224 passengers and crew on board. More than 1,500 people died.
It was found in 1985 and remains a lure for nautical experts and underwater tourists. — NNN-AGENCIES
