You could have asked TR what was wind strength/dir and time of day of his flight – but you still wouldn't get it – the local weather on the Mull at the time of the crash was as expected given the forecast (with some local knowledge) as per the witnesses in the positions to know.
Are you saying that they were in IMC that close in or that they were in the clear but it was beyond their ability to do anything to avoid the low hill? - either way, you are not giving them much credit.
Why is it that you will not consider the case that the hazard was seen but because of the clag on it judgment of range to it was difficult?
Is it because this would infer that they could have easily avoided it unless they had a business to approach it closely?
