    Re: Fw: Grounding of cruiser PORT ROYAL

    This is exactly the sort of case where people lose situational awareness. They 
    were worried about other things. The captain was trying to break records 
    getting that vessel out of the shipyard on little sleep, and he was going out 
    of his way to make the "aviation assessors" happy (probably because that 
    meant he could get to sea one day sooner).
    So why didn't they worry about the Voyage Management System complaining about 
    a position discrepancy between GPS and (presumably) INS? My guess: the system 
    wasn't fully functional yet. This was a trials cruise, and they probably had 
    some other reason to be suspicious of the navigation system. They entered 
    incorrect initialization data for the INS and the VMS noticed the discrepancy 
    right away (damn computers). What does this tell us?? Ironically, trust the 
    electronics. They're probably right, and no matter what, drop anchor and stop 
    rushing things. Computers can be wrong, but they are never sleep-deprived, 
    and they don't worry about the happiness of aviation assessors, and they 
    don't care about their careers.
