A desperate search mission involving a remotely operated vehicle is underway to rescue a Titanic tourist submersbile which has vanished 12,500ft below the Atlantic Ocean with around 70 hours of air left.
The Joint Rescue Coordination Centre in Halifax, Nova Scotia, said the OceanGate Expeditions vessel carrying five passengers, including British billionaire Hamish Harding, went missing at around 9.13pm Sunday, about 435 miles (700 kilometres) south of St. John's, Newfoundland.
The sub was taking a crew of five people - including OceanGate CEO Stockton Rush, French explorer PH Nargeolet and Harding - to the famous Titanic wreckage as part of its $250,000-a-head tour.
If the crew can be found, this operation would be 11,000ft deeper than the deepest successful undersea rescue in history - when British engineers Roger Mallinson and Roger Chapman survived their submersible Pisces III getting trapped on the seabed at a depth of 1,575ft off Ireland in 1973.
In a press conference on Monday, the US Coast Guard refused to comment on whether any manned vessel was capable of reaching 12,500ft but it did confirm that sub-surface assistance was on its way.
David Concannon, an adviser to OceanGate who had actually planned to be on the expedition, said that officials are working to get a remotely operated vehicle (ROV) that can reach a depth of 20,000ft to the site as soon as possible.
ROVs are robots which function underwater on behalf of a crew on the surface. They are fitted with at least aquatic thrusters, cameras and lights and may also have mechanical manipulators, sonar and magnetometers.

10 People Who Did Not Board the Titanic
An incredible stroke of bad luck that turned out to be good luck befell three prominent industrial leaders(Henry Clay Frick, JP Morgan, and J. Horace Harding)who were all set to board the Titanic, in April 1912. The three are linked so I listed them as a single entry. Henry Clay Frick, one of the wealthiest Americans of the early 20th Century with vast holding in steel manufacturing, originally booked passage for himself and his wife aboard the Titanic, in February 1912. But while they were in Europe, Mrs. Frick suffered an accident in Madeira and sprained her ankle. Upon arriving in Italy she was admitted to a hospital. This caused a delay in the travel plans for the Frickโs and they were forced to give up their suite aboard the Titanic. Instead, the suite (B-52, 54, and 56) went to JP Morgan. Morgan was, of course, one of the wealthiest and most powerful men in the world in 1912, with his vast banking fortune. But Morgan himself was forced to alter his travel plans when he decided to prolong his visit in Europe. The reservations were once more turned over, this time to J. Horace Harding and his wife. Harding was another prominent banker. But the couple was able to get an earlier sailing date aboard Mauretania. The unlucky suite would eventually be taken by White Star Line Chairman J. Bruce Ismay.
