I was just trying to figure out this" no need for an investigation" comment of yours and this claim about "foggy weather".....
I thought that many of you where jumping at the "bad wx/pilot error" conclusion, which is too often shouted out here when tragic like this one happens.
maybe you where not with your comment and I misunderstood it.
but according to the other pilot the helicopter started spinning in mid air,
first thought from that is mechanical failure.
