As someone who has just a few hours in the Nimrod, and I have enjoyed every minute of them, I can get quite defensive about the aircraft. Yet......there has to be time to call it a day. Remember the Bahama Mama, the aircraft with the "impossible" total electric failure that went to Istres. I am sure there is a few more which I can't remember offhand.
It is not the fault of anyone at the front-line if there is now a problem with the aircraft. It worries me immensely that there was evidence of a post AAR fuel leak recently, if its the first, or the unfortunate case of the loss of 230 I don't know. But it may be time for a "capability holiday" wrt to AAR until this is sorted.
You can't blame the groundcrew, or the aircrew or the authoriser. All will run with the best advice available at the time from the relevant specialist authorities but the constant dilution of experience on every front at ISK seems to herald time.
