Firstly....'One Nimrod has also been taken out of service and stripped down to check for mechanical problems'......
Use of the word 'has' implies that it has actually happened. To the best of my knowledge it remains an intention. I asked the question before on 12th July, and (as with most of my questions) got no reply. But has the aircraft actually left Kinloss yet, or is it just 'going to' at some point!
The answer is now Yes.
