After the Costa Concordia made the headlines by running onto a rock off the island of Giglio in Italy, we've received many questions whether this could have been prevented. Now we can't tell what happened exactly on the bridge of the Costa Concordia the night of the grounding, but we have made a small reconstruction based on theAISAutomatic Identification System (AIS) is a system, where ships transmit their navigation data to other ships for enhanced safetydata.
We used our Qastor Pilotage software to replay the final minutes of the Costa Concordia and show the sort of warnings that are available to the mariner in today's software.

We have created a more detailed version of the reconstruction. Please note that we have used interpolation to fill in some of the position gaps of the original movie.

On the 14th of August 2011, the Costa Concordia made a passage close the Island of Giglio. This is a reconstruction of this passage.
