I should pose your question re Brian's "QC's" to Brian himself, JP. I understand that a QC is investigating Nimrod Airworthiness (or lack thereof). Seems to me that if he is the man for that job then perhaps Chinook Mk2 airworthiness might come under a similar (or even the same?) Review. Interestingly you do not comment on my preferred option that the Royal Air Force reopens this Investigation on its own volition. Unprecedented to do so against the wishes of the MOD perhaps, but then we live in unprecedented times, of an Airworthiness Authority knowingly foisting unairworthy aircraft onto the Royal Air Force. Perhaps it is time for some of the glittering stars in the firmament with titles such as "Air Officer Commanding" or even "Air Officer Commanding in Chief" to do a bit of Commanding and a little less Career Development?
