Here are the latest developments in the search for the missing Titanic submarine:
- The search for the missing submersible carrying five passengers to the wreckage site of the Titanic entered its fourth day.
- More deep-sea vehicles have been sent to the site as part of an international rescue operation.
- Recovering the missing submersible and bringing its crew to safety in time using the latest advanced deep-sea rescue equipment would be an extremely difficult task, according to an expert.
- The submersible, named Titan, went missing on Sunday during a mission to survey the wreckage of the Titanic, which is 900 nautical miles east of Cape Cod, Massachusetts.
- The sub had up to 96 hours of oxygen supply and by 1 p.m. ET Tuesday was down to 41 hours, according to the U.S. Coast Guard.
- Canadian aircraft detected “underwater noises” in the search area, prompting redirected searches by remotely operated vehicles.
- An OceanGate employee had warned the company that passengers may be in danger.
- The sub is located 3,800 meters (12,500ft) below the surface on the seabed, which is too deep for most remote-controlled vehicles (ROVs) to reach.
- The sub’s oxygen supply is the most pressing factor in the search, but it’s hardly the only challenge, according to an expert.
