ALL FIVE people believed to be on board the stranded Titan submarine have been named - including a father & son and a British billionaire.
Hamish Harding, Stockton Rush, Paul-Henry Nargeolet, Shahzada Dawood and his son Suleman are understood to be trapped beneath the surface.
Rescue crews are frantically searching the Atlantic Ocean after the £200,000-a-head voyage disappeared while heading to the wreckage of the Titanic.
US Coast Guard officials believe the submarine only has enough oxygen to last until midday Thursday.
Four families are now facing a heartbreaking wait for news as planes and boats scour the North Atlantic.
Sonar buoys are being dropped by aircraft as they try to find the tiny sub - which is just 22ft long and can only carry five crew.

After that, no contact was had with the vessel at all - and the five men on board's fate is currently unknown.

OceanGate, one of few companies offering trips to see the ruins, confirmed a major search mission has been launched to "bring the crew back safely".
Tickets for tourists to see the wreckage - which is around 600km off the coast of Newfoundland, Canada - cost up to £195,000.
The company previously revealed it uses Elon Musk's Starlink to communicate with the vessel, however, it's not clear what has gone wrong with the network.
OceanGate's sub - Titan - has the capacity for one pilot and four others and an air supply able to last 96 hours.
US Coast Guard believe they have until Thursday to rescue the stranded sub before they run out of oxygen.
A spokesman for OceanGate said: "We are exploring and mobilising all options to bring the crew back safely.
"Our entire focus is on the crewmembers in the submersible and their families.
"We are deeply thankful for the extensive assistance we have received from several government agencies and deep sea companies in our efforts to reestablish contact with the submersible.
"We are working toward the safe return of the crewmembers."
US Coast Guard Rear Admiral John Mauger said US and Canadian ships and planes have swarmed the area, some dropping sonar buoys that can monitor to a depth of 13,000ft.
Former US nuclear submarine commander David Marquet warned it is "too deep" for military submarines to save them and a highly specialised vessel similar to Titan needs to be rushed over from another part of the world.
He believes there is less than a one per cent chance of the crew surviving "if they are on the bottom".
Captain Marquet told Good Morning Britain: "Time is running out in terms of their supply of oxygen, which they're going to want to try and extend.
"If they're still alive, they're going to want to try to relax, minimise their oxygen use, minimise all physical activity, they're not going to want to panic and get excited and they're going to want to take naps because that's a good way to minimise your oxygen use."
The Titanic sank on its maiden voyage to New York on April 14, 1912, after hitting an iceberg.
More than 1,500 of the 2,200 passengers and crew onboard were killed, and many died within minutes of being thrown into the -2C waters.
The decaying wreck of the 822ft liner was first discovered in 1985 but due to its depth and strong currents even the best underwater cameras have only offered a small snapshot into its colossal remains.
Its bow and the stern that broke apart during the sinking lie more than 2,600ft apart and are surrounded by an unending field of exposed debris.
But last month, the ship's haunting wreck was revealed as never before in stunningly detailed 3D scans on the ocean floor.
Scientists hope the high-resolution digital images - the clearest view ever of the world's most famous shipwreck - could shed new light on the disaster.
The British luxury passenger liner took under three years to construct, costing around £1.5million - equating to about £170million today.
Thousands of workers were involved in the project, with some 14,000 men employed during the peak of construction.
The frame was fully formed in just over a year, with the shell plating finished shortly afterwards.

The steamship was released from its dry dock in 1911 and work on the interior began.
Just eight days before its maiden voyage, it was declared seaworthy.
