Just a little more info on the incident that my friend was involved with, at the point of landing, it was a conventional skids level touch down, the body then fell over to the left bringing the pilots door effectivly to the top of the body, at this point my buddy exited the craft and just slid into the sea and pushed away and sort of swam backwards away from the Heli, the heli continued to roll over and became inverted showing the belly and skids, however he quickly lost sight of it and did not see it sink for the sea state hid it from his sight, so it would seem that time is not on your side if you land in the wet stuff!
