DV,
I'm impressed with your knowledge. However, I must correct your last sentence. On the date of that incident (Nov 06), the SCP was not cleared for use. It is important for everyone, with any interest in the accident, to know that not one single Nimrod has flown with its SCP cleared for use since the loss of XV230. Other system limitations and prohibitions have also been in place since the accident, thus making the aircraft completely safe to fly and to conduct AAR.
