What is clear is that there has been no repetition of this tragedy despite there being no major modification to the Fleet as a direct result of Technical Failures which caused the crash. The reason for this is that there was not then (and there is not now) any evidence of such a Technical Failure.
Surely just because no evience exists does not mean it wasn't there/didn't happen?
Perhaps you would wish to comment on the disregard of STCASI's and GASO's?
Well that is / was SF! This was an SF crew, doing what was mandated to them, ie undertaking the task.
'Finally; perhaps you would agree that, if you are using a chart and log prepared by somebody else, it would be a good idea to check the "waypoints" to ensure that they are actually where you think they should be?'
And SF crews do this ad nauseum... I doubt Ric, Jon and Graeme (and probably Kev too) would not have double checked the planned route to the nth degree.
If there was a difference between the waypoint on the Mull, with reference to the light house and the landing site, then the crew would have been aware of it.
