Bruce;
Others have paid with their lives to teach them to us.
That is the
only lesson here:
Respect.
And if that notion isn't clear enough for those who can't face facts or still think that this is a radio altimeter or autothrottle problem,
respect for the fact that the machine is always trying to kill you, respect for human foibles and respect for gravity.
This crew did not have respect.
This is not complicated.
