Crashing Submarines

The BBC informs us that an American nuclear submarine crashes due to "complacency". The USS Hartford collided with the USS New Orleans in the Gulf of Mexico causing 15 injuries and over $100M of damage. Incredibly, a navy report states that the crew would regularly "sleep on watch, listen to the radio and slouch on deck". The ships navigator had taken his exams whilst listening to his iPod (seriously). Correction of just one of 30 separate mistakes would have prevented the crash. The captain has been relieved of duty.
