CBS News aired a short special this morning on its show "CBS This Morning: Saturday."

CBS says that safety experts are concerned over the safety of large cruise ships that have grown to unprecedented sizes. Jay Herring, a former Carnival Line senior officer and the author of "The Truth About Cruise Ships," joined the show and talked about how cruise ships are getting larger and larger.

He also talked about one of my favorite topics, namely the emergency evacuation chute on Royal Caribbean’s Allure and Oasis cruise ships.  There are not enough life boats on these giant ships.  So crew members have to jump down a chute 60 feet down to a rubber life raft in cases of fire or sinking of the ship.  It’s a waiting disaster if an emergency occurs in rough seas far from land.
