OMS, your link takes us further down the road hinted at by your previous one at #618, and MBL appears likely to remain at Chalgrove. The withholding of evidence has resulted lately in the release of many from prison who were thus improperly convicted. Some can fess up to systemic failure it seems, but not so UK Military Air Safety unfortunately.
This thread is about the avoidable and tragic death of Sean Cunningham. The system that should have prevented his death instead ensured it and cries out for total reform. Instead we have the farrago outlined by tuc above.
MBL will remain at Chalgrove, the MAA will continue to deny the truth, and the VSOs responsible for the broken state of UK Military Air Safety will continue to be protected. Or at least that appears to be the de facto policy of the RAF High Command...
