So now the facts DB- and they are facts - don't match your perception of the video, you lack the honesty or moral courage to admit you fired from the hip and criticised a crew, assuming they were cowboys because they were in a video that you didn't like the look of.
Now even you must understand that hill fog - which is just cloud on the ground - can be formed in hilly terrain such as the Lake District very quickly and can be extremely localised - can you not understand that this wasn't a 'push on into a lowering cloudbase and poor vis' situation but instead a sudden appearance at the top of a steep sided valley, of said hill fog. Note the steep-sided valley descriptor which forced a slow-down, go-down with no immediate option to turn round. Once established safely in a hover, but engulfed in the forming hill fog, the turn around could be completed and the exit strategy (hovertaxiing on a line feature which was the SAFEST thing to do) employed.
Do please carry on trolling about this but I don't think I am the only one asking questions about your experience or problem with either SAR or SF flying.
Nigel, grow up you are better than that.
