Looks like Capt M should not have submitted his 64 page report to the DG. The plan for the 777 was already underway. It's a simple matter of economics so I see it not only as a waste of time but getting your name on a list that will affect you in the future.
I left JED, after many years, about six months ago. Honestly, I was treated fairly and was upgraded through the system. Patience and a sense of humor certainly helped.
