Divers are racing against time to locate six missing passengers from Mike Lynch's superyacht, the Bayesian, which sank off the coast of Porticello, Italy, after being struck by a fierce whirlwind. Despite the rescue of 15 individuals and the tragic death of the yacht's chef, hopes are dimming for the missing, including Lynch and his daughter, as search efforts continue. An engineer indicated that the missing might still be alive in air pockets 164 feet underwater, but divers can only stay submerged for ten minutes due to the depth. Italian authorities have opened an investigation into the sinking, focusing on whether crew negligence, such as leaving hatches open, contributed to the disaster. The urgency of the situation is underscored by experts who state that the next 24 hours are critical for any potential rescues. Rescuers are using a mix of divers, helicopters, and remotely operated vehicles in their ongoing search efforts.
