I think that you're right Pontious.
I'm not professionally involved in the Shoreham aftermath, but have acted as an expert witness in many other UK crash related cases. I have always used AAIB reports as evidence, but have always been expected to provide my own analysis to the court, answering the questions that matter - which are different questions to the "how to avoid a recurrence" questions answered by AAIB. I've seen and heard nothing likely to change that.
