A lot of people - the Great British Public, the press, MP's, the Treasury..... - are going to have a lot of questions if the RAF ground Rivet Joint on the basis it "is not airworthy" when dozens of the damn things are swanning around the sky and have been for years without serious problems
No doubt people of the "Common Sense party" & "Health & Safety gone mad" views will also be heard
From the outside it seems that the MoD is saddled (or saddled itself) with a Safety system that impedes the acquisition of anything but new aircraft documented to UK Standards
I leave it to wiser men and women to decide whether this is a good thing or not.........................
