Winco, thanks for the response, but again, as I have said that those figures average 10 a month over 20 years, and the fleet was a lot larger and sorties more frequent a fact that you concur with, additionally how do you know that over the last 3 years say that the average amount has been a lot less a month due to less aircraft and less sorties (by the way I don't know that figure either).
Additionally the comparison with Tornado IRs over the last 20 years would produce a larger figure (i.e. more aircraft and more sorties), but as I said that percentage wise it would probably be no less or worse than those for the Nimrod fleet or any other fleet for that matter.
Magnersdrinker, thanks, I think that most from the old NMSU, like me have retired, despite WO A it was not a bad time.
