“”If you look that video was taken in 2011.””
Where did you find the 2011 date? On the website it shows 14 Gen 2012 as the date it probably aired on an Italian TV station.
The title of the video is: “Il ‘saluto’ della Costa Concordia all’Isola del Giglio nel 2011”
There’s another video that appears the same simply titled: “Costa Concordia Agosto 2011”. I know when they were posted but it appears the video was taken last summer.
