I can say that it has not always been the case that the F700 flew with Nimrod a/c.
People that I have spoken to can not believe that the main a/c document, which contains the basic history and from which all other document flows, is allowed to fly with the a/c. I my time if an accident happened the first thing that was done was to impound the F700.
No wonder it is taking the BOI so long, they are having to work backwards.
