I understand the sensitivities. I knew one of them. But certain facts have been established by the AAIB. There is no evidence of mechanical failure. There maybe some additional contributing factors but The liklihood of finding that evidence is probably slim.
There isn't much more to speculate on is there? This accident has the hallmarks of other accidents or near acidents.
Those of us with thousands of hours of offshore flying, especially in the dark UK winter have all been in a similar situation, it just that we had a different outcome.
Sad business.
