A sad day, Judith and Philip were a very nice couple with lovely children. As a neighbor it is a bit of a shock for all around here. The loss of father and son must be truly devastating. I did not know the pilot or the other passenger but I feel for the families of them.
A couple of facts: We heard a helicopter go over the top of us at the time of the accident, I assumed it was mil or police and went out to look. The weather was appalling, thick fog and overcast around a couple of hundred feet. My drive is approximately 200m long and then end of it was in mist.
This is approximately 3 miles from the accident site and about the same from Phillips house. The fog came down very quickly from a clear sky at 10pm to solid fog at midnight.
The RAF Wittering weather station gives only METAR not TAF.
