A British engineer who survived after his submarine sank 457 meters off the coast of Ireland 50 years ago has a "terrible feeling" about the lost tourist liner Titanic.
Roger Mallinson, who along with colleague Roger Chapman were repairing a telephone cable on the seabed in the Celtic Sea, described the case of the missing Titan submarine as "terrifying" as he recalled his nightmare in 1973.
The missing OceanGate submarine has been compared to the sunken submarine he was on, whose crew members were rescued after an extraordinary 84-hour rescue operation that brought them back to life with just 12 minutes of oxygen left.
To date, it is the deepest successful underwater rescue in history. Speaking about the ongoing search for a deep-sea diver who disappeared with five people on board while descending towards the wreckage of the Titanic, Mallinson said: "It's terrible."
Mallinson told Sky News: "I can't understand why they haven't transmitted a signal of any kind. I have a terrible feeling that something could be seriously wrong because they are unable to transmit a signal.”
Time is now running out for the five adventurers as their oxygen runs out on Thursday - and the group is thought to have at most a one per cent chance of survival. The Coast Guard said today that it may not be able to salvage the submarine even if it finds it.
Many people have a positive view of the submarine disappearance, precisely because of the creditable rescue in 1973 of Mallinson and Chapman, whose mini-submersible fell 1,575 meters below the surface with 80 hours of air after an accident 150 miles southwest of Cork, Ireland.
Their fall sparked a massive international rescue operation as they escaped with just 12 minutes of oxygen.
Asked if he ever thought he wouldn't make it out of the stranded submarine alive, Mallinson said: “We certainly did, even though we thought we wouldn't. Anyway, 84 hours was a very long time. We had enough food, but we didn't have enough oxygen, we didn't have enough batteries to power the scrubber.
We just had to do everything together and take care of each other. We took care of each other and that was the main salvation."
Friends and relatives of the five missing submariners will now be hoping for a similar outcome.
Mallinson revealed that his last-minute decision to steal an oxygen tank was the reason he survived.
"Fortunately before we started diving, I stole an oxygen cylinder," he said, reports the Daily Mail.
