The families of loved ones missing from the sunken Bayesian superyacht are holding out hope for air pockets - though the reality of living in one is terrifying. In the early hours of Monday morning, the 56-metre luxury yacht, carrying 22 passengers, sank off the coast of Italy after it was suddenly hit by a tornado . Fifteen people have been rescued and one person - chef Recaldo Thomas - has tragically died, while six people - including British technology tycoon Mike Lynch and his teenage daughter - remain missing.
Divers from Italian emergency services continue to look for those who have not been accounted for - but time is running out. The sunken vessel currently sits fully intact on its starboard side around 165ft underwater on the seabed. Due to its location, experienced divers can only explore the wreckage for around 12 minutes at a time.
With a maximum of two to three days before the situation becomes fatal , relatives are fearful. However, it is possible that survivors are trapped inside, thanks to air pockets that may have stopped them from drowning. Vincenzo Zagarola, a spokesperson for the Italian Coastguard, said: "We think they are still inside the boat, that is our very hard idea.
" Harrison Okene, then 29, astounded the world when he survived three days in a capsized boat in May 2013. He was working as a ship's cook off the coast of Nigeria when a wave hit the boat and sent it 100ft under the water. Harrison struggled to escape and instead settled in an air pocke.
