Those who think Andy Hill is solely to blame haven't been paying attention to pprune over the past 20 years!
I believe the AAIB report was not allowed in evidence? Yet was discussed at length here and available to anyone who wanted a look. Maybe the jury thought there was too much unheard evidence to convict on beyond reasonable doubt? It's a high bar when there's a report listing the defects and that the thing shouldn't have been flying.
