What we have here is a classic case of negligence by people who were, because of operational requirements, placed in a position of authority beyond their capabilities. This is demonstrated by the crews allotted for the various tasks allocated to the detatchment that day.
The two experienced Chinook Pilots were allocated to the in-theatre support tasks and the inexperienced (on Chinook) RN Pilot was allocated (with an RAF Navigator) to the VIP task. This 2nd crew (quite rightly) declared themselves unsuitable for the task in view of the weather
The 2 pilots of ZD576 had not done the planning for the sortie - but they obviously did not check the Lat/Long postions entered into the Nav System. That alone warrents the finding of "Gross Negligence".
