Casting aside for a moment the hideous spectre of maladministration coupled with collusion at high levels in the MOD, I wish to focus purely, like many, on the departure from established 'rules' at BoI and reviewing officer level.
I think it useful to compare the findings of the Tornado fatal at round about the same time. Cause 'unknown'. For those who wish to speculate on the probability of pilot error, far more 'circumstantial' evidence, is there not? Was it found 'without any doubt'? No.
Why a different 'verdict'? As with many things in life, as soon as one sees a lack of joined-up writing, one begins to suspect.
