Titanic Wreck Dive Ends in Disaster as Submersible Craft Goes Missing with Seven Crew Members Aboard

Two men who have made the same trip in a tourist submersible that has now gone missing during a Titanic wreck dive have shared their fears over whether those stuck inside can escape.

The craft went missing in the Atlantic Ocean on Sunday, prompting a major search and rescue operation.

A journalist who traveled aboard the submersible said it would be impossible to escape without help and it would be challenging for rescuers to find it in time.

The vessel, believed to be OceanGate's Titan submersible, had seven different functions to allow it to resurface, but none of these have worked so far.

There is no backup or escape pod in the vessel, making it a cause for concern.

Rescuers are racing against time to locate the missing sub, which normally carries around four days' worth of oxygen for a crew of five.

However, communication is lost during all three of the dives, including that to the Titanic, and there is currently "no way" to communicate with the vessel.

The inventor and CEO of OceanGate have claimed that the carbon-fibre main capsule is "rock solid," but problems can arise due to the nature of the expedition.

The submersible craft Titan, owned by OceanGate, has gone missing with seven crew members aboard while exploring the wreckage of the Titanic.

The company has expressed its focus on the missing crew and gratitude for assistance from government agencies and deep-sea operations companies.

The Titanic sank in 1912 after hitting an iceberg on its maiden voyage from Southampton to New York, resulting in the death of over 1,500 of its 2,200 passengers and crew.

The wreckage has been extensively explored since its discovery in 1985.
