Not facts just conjecture and a few questions....
Reclaimed bodies intact - no seatbelts?
No lifejackets - no time or no announcement?
Not many found - most remain within fuselage at time of impact?
Bodies found were generally unclothed - does this indicate leaving the aircraft at altitude or does it deny this?
Few pieces on the surface - Would an object the size and construction of the aircraft hit the surface at very high speed and not disintegrate.
Add to this the condition of the gallery component (it doesn't have the apearance of something that dropped a few thousand feet) and it is difficult to escape the feeling that the aircraft broke apart relatively near the surface of the sea and at a relatively low airspeed.
