I think the BBC did a reasonably good job of emphasising the problems entrenched within the Nimrod MR2 fleet. Yes there were inaccuracies, and yes there was selective editing, but the message was very accurate.
Robbing and poor serviceability has been a part of life on many fleets for years, but it is the extent that this applies to the Nimrod force at the moment that is raising alarm. An inadequately funded, understaffed, over-tasked RAF, with increasingly low morale, cannot continue in its present condition, hence the obvious nervousness seen by CAS. Add into the equation an old, heavily-used aircraft that is well past its sell-by date and you are asking for trouble.
The elastic band is about to snap, if it hasn't already.
