We are in possession of the information that the AAIB has not seen fit to change its findings in the light of the court verdict,
I would question the relevance of that. An AAIB investigation some time ago (in the case of a microlight fatal accident) resulted in a manslaughter prosecution. In spite of the fact that the report was so riddled with errors that were pointed out in great technical detail, they refused to acknowledge their errors. AAIB are not infallible.
