Lonewolf - thank you for your comments and I thoroughly agree with your points 1 and 2
On the subject of tone, it is a problem of the written word in the hands of non-gifted writers like me, that what is written with one intention is easily interpreted in a different way by others.
It is sometimes difficult to let go from my past roles as a Squadron Training Officer and Flight Safety Officer charged with maintaining standards and professionalism on an operational unit.
If the crew involved in this accident had been one of mine, they certainly would have been listened to in order to establish why it happened but also re-briefed on areas where they might have let themselves down.
