Northwest Pilots

As you may have heard, Northwest pilots overshot an airport.  By 150 miles.  Because they were on their laptops?  We all were discussing this today and it's highly doubtful that this happened, and most likely they did fall asleep.  It's nearly impossible to not hear communications from towers, even using a laptop or arguing.  So, this is where everyone tells me "be safe, don't fly tired, etc".  I hear the warnings and I promise, promise, promise, I'll be safe and won't fly in bad conditions, whether it's weather of physical.
