Chug,
You really won't give up on this but you will just have to accept that in the RN it just would not happen the way you describe it. The SI team leader in ANY SI (aviation or not) is given complete freedom to get on with his SI without interference. Heavens knows the RN has had some good ones to look at - NOTTINGHAM grounding, ENDURANCE flooding, BRAZEN on the rocks etc. The RN interest it to get at the facts and the truth so that all can learn and move on - they are not interested in a fudge.
