Ron Allum,whose submersible carried Titanic director James Cameron to the bottom of the ocean in 2012,agrees time is running out for the missing Titan.
As the search for the missing Titan and its five passengers enters its third day,documents have placed OceanGate under fresh scrutiny.
Almost two days after the Titan disappeared off the coast of Canada,a mass search and rescue operation has so far failed to locate the vessel;however,banging noises have been detected in the search area.
The Titan submersible had been in the area to explore the wreckage of the Titanic,which sank on its maiden voyage in 1912.
Many have fallen under the spell of the sunken ship but,as the missing sub reminds us,few have ventured to the depths below to see it.
The five passengers on board the vessel have just 96 hours of oxygen,starting from about the time it began its descent to view the wreck of the Titanic.
The Cambridge-educated jet pilot,missing on the Titan submersible,holds 16 air speed records,including the world record for the fastest circumnavigation of the Earth.
A submersible that vanished in waters off Canada during a tourism expedition to explore the Titanic could have as little as 70 hours of oxygen left,with a British billionaire among those on board.
