One good thing that has come out of this tragedy is the development of new systems for the prevention of a recurrence.
Here's an example of one such system:
It's an Early Warning System that would give cruisers enough advanced warning of impending trouble to enable them to be prepared.
It's new from Italy. It's called The Schettino Early Warning System.
It's very easy to operate. It just hangs out at different parts of the vessel (the salon is a particular favourite spot). When it perceives danger the Schettino automatically ejects itself from the boat.
Having left the boat the Schettino will 'fall' into any vessel that is in close proximity - ideally the pirate ship.
Once safely aboard the other vessel the Schettino will lie on the deckboards making incomprehensible and fantastical statements and whimpering inconsolably, thereby totally confusing anyone within earshot.
Here's what the unit looks like:
And here you can see that the Cruise industry has reacted very quickly and equipped some of their liners with this new piece of safety equipment:
The Schettino Early Warning System: Safety First! Everybody else is on their own.
