Sir,
In the context of this thread I think I have highlighted the important words
"My point was and is - the aircraft was flying VFR.(I do hope that no-one thinks they were flying IFR at that height).One pilot would have been flying the aircraft and looking out of the window. He would have seen either land/sea or fog. If he saw fog he should have done something pretty damn quickly as he would have confidence in his DR/TANS nav and knew he was extremely close to the hard stuff. If no-one was looking out of the window but were heads down in the cockpit dealing with some unknown problem, that is wrong. One person in the cockpit should always FLY the AIRCRAFT in a safe and proffessional manner no matter what distractions there are elsewhere. The recent crash of a Turkish airliner at Schipol seems to be a classic case of no-one flying the aircraft.
I do hope that this is not rude! Sir ,I am sorry if you feel that quoting you is rude - it is certainly not meant to be.
