Latest buzz on the demise was that a strong smell of burning was apparent whilst in the dip, so the ball was raised and the P1 turned for dry land. Tight feeling around the backside urged the driver to carry out a controlled ditching, and on finals into wind all went pear shaped. As discussed, the r/b had either not backed off completely, or had come on uncommanded, and started a fire forward of the MGB. Following the Italian fatal the control rods are now stainless steel, unlike the previous composite construction, so they were OK, but as the fire progressed back around the MGB it took out the tail rotor drive shaft, which let go just before ditching. Water entry was about 15 degrees off wings level, and the rest is history.
It's only a rumour network, if anyone asks.
