Was the weather suitable. Only witness (who could see the aircraft), Holbrook says yes.
That is correct in the short period just before impact. However more than one witness on the ground stated that immediately after impact their visbility "across the hill" was over 400 yards (in the context of seeing wreckage been strewn, before it settled). Others said they were in thick fog, but one of the emergency services said he later stood on the hillside with his feet in mist yet could see clearly out to sea. I think all that emphasises the patchy nature of the ground hugging mist and is certainly not a description, as presented by the ROs, of thick fog extending some way out to sea.
Good posts Winch Control. The CPLS Service Deviation says Station 160, with Troop Seat #1 removed.
