I must then ask why it is that the coroner's report goes into areas where he knows BFA.
I sat through virtually the whole duration of the coroner's inquests into the deaths in the RAF Hercules that was shot down in Iraq and the Nimrod that blew up in Afghanistan. I came away with a great admiration for both coroners.
Neither had, as far as I know, any previous aviation expertise, but both had clearly done detailed research into the necessary areas. They demonstrated an impressive ability to understand the detailed technical evidence placed before them. They were able to conduct forensic cross-examination of witnesses, and I was particularly impressed by the way they could sort the wheat from the chaff.
So I suspect that the coroner in this case was probably similarly well prepared and professionally capable.
