Droopystop,
You need to look at the Tail Rotor blades, smashed beyond repair, caused at a wild guess, by rotating at speed prior to impact with the water!!!!
Nobody is focusing on anything right now cos nobody "Knows" anything other than what can be conjectured from the images we have seen.
I am not an aerdynamic specialist, but if the tail "fell off" inflight I am convinced that the resulting yaw rate, coupled with a massive unfavourable change in the CG (way beyond the limits) would cause a far less favourable outcome than a main fuselgae, sat upright on its floats and the ensuing orderly evacuation.
Whilst this is a rumour network surely it may also accommodate the odd calculated speculation.
Make of what you see.......what you will.
In my considered view it hit the sea intact. The question remains what made it hit the sea?
The silence, as ever, deafening from those who must by now have a fairly good idea of at least what started the incident.
However, If I am in minority of a few, so be it, but to not press hard for information is surely the biggest dis-service to all concerned.
