Minus the Rotor head and in a tumbling motion that is about the order of magnitude which I would expect to see.
As some already wrote before: teetering head in up to 70kts of gusts at night over water in bad weather with questionable avionics suit for that purpose and unclear NVFR/IFR experience of the pilot.
What could possibly have gone wrong here?
Very tragic. But for sure I don't expect any novel cause of an accident in this particular case.
