This BOI felt unable to agree on a cause for the accident
In a sense, I guess you are correct. But presumably they agreed the text of the report signed off in their names.
I'm sure you will remember what they wrote:
The Board was unable to positively determine the sequence of events leading up to the accident, and therefore concluded that although it is likely that Flt Lt Tapper Made an error of judgement in the conduct of the attempted climb over the Mull of Kintyre, it would be incorrect to criticise him for human failings based on the available evidence
and:
The Board concluded there were no human failings with respect to Flt Lt Cook
As those tasked with the investigation, one can only assume they knew
at least as much as any subsequent commentator. (Including you.)
It's time.
