Huh? "How to use and not use a GPS' lessons seems to be written all
over it. But if you just want to knock the pilots, then nothing will be
learned. My personal conclusion and lesson is that you need to stick
with your primary navigation instruments and use the backup as backup.
But that's me.


There are no new lessons to be learned from this accident. Because of
the lack of a CVR the NTSB is being speculative about the use of the GPS.
