The Titanic rescue mission is 'relying on pure luck' as the oxygen supply is said to have already ran out, an expert has gravely claimed.
A fleet of rescue vessels are desperately searching the water close to the Titanic wreck, around 435 miles south of Newfoundland, Canada.
The sense of urgency comes as expert state oxygen will run out by 12.08pm today, with rescue teams no closer to finding the five passengers.
