Costa Allegra, the 28,430 gross ton cruise ship of Costa Crociere that lost power in the Indian Ocean after a fire in a generator room, has been taken in tow by deep sea trawlers and passengers will be evacuated on the Roche island, media reports say. The Roche island is located a few hundred miles away from Mahe, the Seychelles capital. Planes that can land at Roche can only take about 20 passengers, so it is expected to take a long time before the 636 passengers will all be flown to Mahe and then onwards to their home destinations, a report on BBC news website says.
