The sinking of the MS Estonia on Wednesday, 28 September 1994 is the deadliest peacetime sinking of a European ship, after the Titanic, in 1912. The aging ferry was crossing the Baltic Sea in rough weather on the route from Tallinn, Estonia to Stockholm, Sweden when it was lost, killing 852 people, out of the 989 who were aboard. The victims were mostly Swedish and Estonian, though the total number of victims included individuals from 17 different counties – their bodies remain with the wreck, a sea grave that now has protected status, and has been partially entombed by the Swedish government. This episode delves deep into the engineering failures behind Europe’s most deadly modern-day maritime disaster and details the improvements in ferry safety regulations and life-raft design that came about as a result of the disaster.
