Perhaps as an 'SH' man, you will recall a fatal chinook accident in the Falklands, when an aircraft nosed over, and crashed into the ground killing all those on board.
The only radio transmission being the middle part of a two word expletive.
Because this accident occurred in good weather, and was seen by a number of observers, 'pilot error' (and negligence) was immediately ruled out.
However, NO examination of the wreckage by W/C Pledger and his team was ever able to determine the technical cause.
There is also a well documented account of a US army CH47 completing an undemanded aerobatic manouvre. The crew were utterly powerless to stop it. Having survived to give their evidence, AGAIN no technical examination was able to determine the cause of their loss of control.
You may wish to consider whether absence of evidence can EVER be taken as evidence of absence.
In view of the results of ALL independent examinations of this case, which ALWAYS reach a conclusion opposite to the two Air Marshalls, it is pretty clear that they (and you) are the ones with their fingers stuck very firmly in their ears.
Not those of us on this side of the issue.
