'The plan was relatively simple: a sister sub would go down with a two-man crew and attach a specially designed grapple hook to the sub then lift it to the surface,' McGinty explained.

'It was very cold - we were wet through.' The rescue operations suffered a series of setbacks 'We hardly spoke, just grabbing each other's hand and giving it a squeeze to show we were alright,' Mallinson told the BBC. They lay in the pitch-black submersible as high up as possible, where the air quality was better, thinking about their families. Once they telephoned for help and made sure the nearly upside-down vessel was in order, they didn't talk or move. The two decided to conserve oxygen by doing as little as possible. Mallinson and Chapman didn't have a water supply, just one can of lemonade and a cheese sandwich, which they wanted to save for later.īy a stroke of luck, Mallinson had replaced the oxygen tank just before the dive - but they only had 66 hours left.

On the morning of August 29, as the two were getting ready to be towed back to their mother ship, a hatch was accidentally pulled open. They were clocking eight-hour shifts, crammed into a small vessel with very poor visibility, according to the BBC. Former Royal Navy submariner Roger Chapman, who died in 2020, was 28.

It was August 1973, and two British sailors were heading out on a routine dive to lay transatlantic telephone cable on the seabed about 150 miles southwest of Cork.

'You just rely,' he said, 'on the thing being well-made.' The submersible after a routine dive One of them, Roger Mallinson, told NBC News on Tuesday that the search for the Titan has evoked tough memories of his own experience. In that dramatic incident, two crewmen - both named Roger - spent three days trapped in a vessel measuring 6 feet in diameter, subsisting off a single sandwich and condensation licked from the walls, until they were rescued with just 12 minutes of oxygen to spare.
