British tech tycoon Mike Lynch and his 18-year-old daughter Hannah Lynch are among the six people still missing after a British-flagged superyacht, named the Bayesian, sank in a storm off Sicily on Monday. Fifteen people, including a woman and her one-year-old baby, were rescued; one body has been recovered. Divers have been struggling to enter the wreck which is lying on its side, nearly 50 metres under the water. We assess the challenges facing rescue teams with a marine salvage expert.
