Cruise Ship Greed Puts Passengers At Risk

From the New York Times:

...nearly all ships lack backup systems to help them return to port should power fail because to install them would have cost operators more money.

We love cruises but the recent disasters are a concern. Brand new ships must have back up systems by law but that doesn't help passengers on existing ships. Too bad that operators are not forced by law to make some provisions for loss of power at sea.
