If I recall the prior discussion in HN correctly, the flight path was abnormal well before the impact. This contradicts somewhat that it was a surprise nose dive. Also, the pilot asked for return to the departure airport without indicating an emergency. The last discussion speculated somewhat about unsafe center of gravity which I found more convincing. We'll see.
