You seem to place a lot of weight on a miss plotted waypoint. My recollection, not good I have to say, is that the only map/chart available to the BoI was the one that was left with the Duty Supervisor on 72 Sqn. This, quite obviously, was not the chart used by the crew of ZD576 during the sortie. I think it fair to assume that this would have been a map made up as a quick copy to show the bare bones of the sortie either with the sole intention of leaving it or even as a ‘quick look’ at early planning which was handy to leave behind as a rough guide should the worse happen.
I have been reluctant to reply to this issue because, as TandamRotor and Pulse1 have already said, the thought that the crew would plan to fly so close to such terrain (with correct waypoint plotting) whilst IMC is ridiculous.
Assuming you have an aircrew background I can only wonder why you wish to put forward such trivial arguments.
