OK:
The posts have trickled down to a few.
Let us all resolve that this crash will at least TEACH us something:
Let every pilot go forth and tell other pilots:
1: Know your plane, inside and out...know the symptoms of problems, and each symptom is not OCAM'S Razor.
2. Do the checklists LIKE YOUR LIFE DEPENDS ON IT...Because it does.
3. ALWAYS CHECK THE KILLER ITEMS : flaps, trim, spoilers, and compass agrees with runway bearing/heading.
IF SOMETHING IS WRONG...STOP, taxi clear of the runway and get it right. Don't try to correct it on the fly as it were.
