JFZ90: It is clear from what you say in your second paragraph to Mick Smith that you do not understand the concept of ALARP. Adding a additional engine to a Harrier is not what ALARP is about.
Furthermore, I can assure you that QinetiQ fully understand the the meaning of "Broadly Acceptable". And whilst they are happy to throw in the non-Def Stan term "acceprable", they are not prepared to go all the way and place "broadly" in front of it.
Was this a way of sending a secret message? I have no idea. What I do know is that the report was initially issued in Sept, for comment. It was then published for General Release in Oct. I say "General Release", it has taken the families of the lost crew over four months to get their hands on a report that claims to give the Nimrod system a clean bill of health.
