Cruise ship "tilt" due to human error

Remember the sudden change in course of the cruise ship that caused it to heel over so much that passengers were injured? It's now reported here as due to "human error":

Human error caused a cruise ship to abruptly tilt at sea last week, sending furniture and debris flying about the vessel and injuring 240 passengers, a cruise-line official said.

Though federal investigations continue, Princess Cruises president Alan Buckelow wrote in a letter to passengers that "the incident was due to human error and the appropriate personnel changes have been made."

UPDATE: After thinking it over, if I were the cruise ship company, I probably would prefer the "human error" causation to any sort of random computer glitch or mechanical malfunction. In some cases, the human factor is easier to fix.
