ARFOR, as a non-pilot that summary looks good. One thing to consider, as an EE who digs RF communications and antennas, is that as long as the plane was nearly horizontal, within 20 degrees or so, more ACARS messages COULD go out if they were generated. That coupled with the high vertical speed component to its encounter with the water in normal flight orientation suggests to me that the flight of AF447 may have ended somewhere depressingly close to the last message at 0214.
(I am (rashly?) presuming that the damage encountered is consistent with the plane hitting with the wings nearly level, at the very least. As soon as one digs in the leverage should produce a distinctive damage profile. I am not sure we can say nose or tail first or purely horizontal, though. My guess, as a preceding message indicates, is that the VS was levered off the plane by the collapsing tail cone from a slightly tail first encounter with the water.)
