Tuc,
I fully agree that the MoD/MAA are not equipped, nor are they inclined, to conduct the sort of investigation required - that's why I suggested a Commons Committee inquiry. Yes, this is just another point on a long and inglorious line of events, and I would hope that any inquiry would connect the points. I'd be happy to help them do that, if asked.
But, as ever, I'd offer the observation that there were plenty of people, in many positions, within the MoD and the RAF, who could have, and should have done their jobs far better than they did. Maintaining airworthiness files? Not hard. Keeping records of repairs? Routine stuff. Maintaining proper support contracts? A doddle. Just not done.
Best regards as ever to all those who have beaten this drum for so long with such integrity,
