Caz,
I am well, thankyou.
You are beginning to look deliberately obtuse if you cannot see that it is not only possible, but extremely likely that although the weather on the mull was thick fog, just a few yards away, below cloud, the chinook was flying quite legally in VMC, obeying the COCIS rule of SH VFR. There is no conflict here.
Just why the aircraft continued, after a routine TANS waypoint change, slightly right, and into the Mull, instead of turning left along the coast, will never be known.
Because of that, the finding of gross negligence has not been proven beyond any doubt whatsoever.
Do I make myself clear?
