Definitely hit the earth wire.
I can relate to what is seen on the footage exactly what I did when I had a wire strike in a H-300 C, years ago
Hit wire with T/R, instinctively pull collective to get away from threat, lost T/R, around in circles I went, chop throttle, on ground, smashed it self to pieces.LIVED
The tail boom looks to have hit the main wires and drag up into the rotors
Bloody terrible sight.
