I just posted a blog called "the exception that proves the rule
." It says that what has been lost on the news media is that this is a big story solely because such events happen so rarely.
Now, I do agree we need to rethink evacuation procedures - to account for situations where the ship is listing badly. The whole premise of evacuation now is that it must be done from an upright position.
As to whether cruise lines know where all of their ships are at any given moment - I think they have the ability to see that - but to assume there is someone on land watching every captain and reviewing charts fulltime to see if he is about to hit rocks is a bit over-reaching.
