Courtney, I doubt anyone who has posted here, including the OP, would disagree with you one iota. But it would be more appropriate if such analysis took place on another forum. This is a military forum and it is the military connections, and in particular UK ones, that are under discussion. I suggest that was clearly the purpose of the OP, and of everyone else who has posted. You suggest that the engineer is a scapegoat, for the pilots, the airline, the airworthiness authority, or whoever. You are almost certainly correct.
So what about the allegations made here about juniors, be they pilots or SOs being made the scapegoats of senior Air Rank officers? What about the allegations of outright lies told by senior Air Officers? What about allegations of corruption and gross negligence by senior Air Officers? What of allegations that the UK Military Airworthiness Regulations were wilfully suborned by, and on the direct orders of, senior Air Officers. These are the points that require urgent analysis by anyone who cares not only professionally but emotionally about the honour and integrity of the Military High Command. In particular it should be the concern of anyone, serving or retired, that the UK military airfleets be restored to airworthiness and be subject to professional air accident investigation. Are we as one about all these issues?
