FWIW:
The former chairman of the U.S. NTSB, Peter Goelz, stated to the media that it was obvious, to him anyway, that the flight deck 'crew was not paying attention' and that the accident is 'inexcusable'.
Pretty harsh words coming from someone of that stature. And especially considering the investigation into the cause of the accident is far from finished. One would think someone like Mr. Goelz would know better.
