Airsound,
I am very interested in your synopsis of the key points from the trial, particularly the expert evidence regarding the 8 / 12 unconnected errors during the key phase of the flight. To me, at face value, the notion that someone could make that number of unconnected errors in the space of 23 seconds points to something else going on, and is certainly worthy of further consideration.
Are you able to recollect what the errors were? I don't remember this being identified in the AAIB report, and certainly don't remember any significance being attached to the frequency of the occurrences. I remain puzzled as to the significance of the distinction between reopening their report and publishing an addendum, but in any event, I hope they clearly address the issue
