I was at the Chester lecture. Alan O'Connor was at pains to report only on publicly available information, rather than give opinion or new information. It was an excellent presentation, humble particularly due to his own role within the system, and cemented for me my decision not to return to flying (or indeed anything else) with the RAF Air Cadets.
Whilst MB have their part to play in the death of SC, they will end up taking the public flack for an event (or series of events) that lead up to the shackle not releasing that had very little to do with them. It'll be a useful smokescreen for hiding why he ended up at 100' AGL in the first place.
