You seem to have joined the small number here who believe that Andrew Walker and/or the accompanying pilot were exclusively culpable for this tragic accident.
Just for clarification, if you'd been an experienced pilot who was to be carried in that aeroplane to collect a twin from Exeter, what if any words of advice would you have given to a pilot proposing to take off, overweight, into a 200ft-base overcast when the TAF for their return was no better, when the pilot had 106 hours total time gained over 12 years and of which only 3.8 were in the previous 13 months, when the pilot's experience on instruments had totalled 1.3 hours, and when the aeroplane had no functioning radio navigation equipment?
