Video shows wrecked cruise ship interior (1:01) - The Washington Post
This one has a video of passengers in a blackout, and you hear (as I have been saying) announcements in Russian, (Spiceba) and Portuguese(Abrigado), Korean - and who knows what else.
The point is that these are in addition to the Italian, French, German, Spanish and English Costa always uses. How many languages were they using on this cruise?
No wonder there was bedlam - this is ship designd to be used by people who do not share a common language.
