A brief summary of this case:
The bottom line is that the MoD/RAF got away with allowing one of their own to die.
Now it seems to be nobody's fault, and so, nobody is to be punished. The lessons to be learned, were already known.
MB get to pay a fine, not one person is in the frame.
The only guy to suffer is Flt. Lt. Cunningham.
Nothing to see here, move along.... until the next time.
