BEA is now saying that AF447 entered the water in one piece, in a
horizontal attitude, but with a high vertical force. That pretty well
describes a flat spin. That would not have happened if the VS
separated at high altitude.

And I see a number of US media sources can't translate French
aeronautical terms correctly, as they are saying the aircraft went
straight down, almost vertically.

Il paraît avoir heurté la surface de l'eau en ligne de vol

Means that the aircraft struck the surface in a horizontal attitude.

avec une forte accélération verticale"

Means with high vertical acceleration, meaning it was in an
aerodynamic stall.

BEA is also reporting that the vertical stabilizer separated from the
aircraft from the back to front, with a slight leftward twist.

They also said that faulty pitots were a factor in the accident, but not
the cause.

Whatever conclusions you can draw from those statements.
