As there were unfortunate deaths in this accident lets not speculate.
We can't sure of the Density Altitude, AUW, W/V or in fact engine output......lets be patient.
Agree OMR .. my point (maybe not clearly made) was the BBC commentator (standing behind the hill) and making a quick summary that the heli hit something ... that is purely speculative - seen from the anglke that he (and we the viwers) where watching.
Anyway agree .. speculation .. rumours .. would be interisting to know the Density Altitude ...
