OMG!! Helicoper crash in New Zealand

I know this should be on Videos but I thought to start a good discussion about helicopters function and how dangerous they could really be
what could possibly went wrong?
I always think that Helicopters has too many pieces ,I saw a tutorial few days ago (I didn't understand How it moves from left to right back and forward ) then I saw all those movable pieces ,The more movable part the more dangerous and risk
Caught on camera the crash
