The right way around
Surely this is a case of the horse going before the cart The Courts Mashall shouldn't have taken place until after the RAF Enquiry was complete. That way all the information would have been available.
The BBC report also seems to imply that the Courts Marshall cleared him of total blame; in other words that he wasn't solely to blame, but leaving the door open for the official RAF enquiry to find him partially to blame for giving an unsafe clearance.
Seems he had a 'lucky' escape at the CM, if it had come after the official enquiry he might now be facing very serious charges. Or does double jeopardy not come into play here?
