2 arses need to be kicked very soundly here.
I am afraid that we are way past arse kicking as a solution to this endemic failure of the RAF to provide airworthy aircraft for its crews Al, but things do indeed need to happen:
1. The CAS should go before he is pushed. His position is untenable.
2. The fleet should be grounded, its job done as best it can be by others, at the very least until the BoI report is published and acted upon.
3. An independent inquiry be instituted immediately to urgently investigate Military Airworthiness Regulation in the UK, with a view to a total and fundamental reform of the system.
As to kicking the arses of those who have allowed this into the open, I can only say that I wish I was equipped with such moral courage. At the very least they may have saved the next crew detailed for AR, more likely they would have set in chain the means of turning around the destruction of the provision of RAF Flight Safety by the bean counters, uniformed and civilian, who have starved it of money. The Times which broke this story has a long record of revealing such logistical scandals, for it was they, was it not, who shone light on the ineptitude of supplying kit unfit for purpose to another British Expeditionary Force, in the Crimea? No doubt Victorian voices were raised then against them, though perhaps in a rather more genteel way!
