Safety Helmut,
EdSett, you have produced some of the more informative posts on this thread, but this is Twaddle !
Let's get something straight, THERE IS NO LEGAL REQUIREMENT FOR A SAFETY CASE.
I didn't say there was a legal requirement to do so, neither did the Air Cdre, so far as I know. He simply said (so I'm told) that, in accordance with the principles of the HSAW Act, the JSP required him to provide an argument that the Nimrod was safe. Its not worth debating this particular point anyway. In a nutshell, the MOD shot itself in the foot when it mandated a safety case that was not required by law, which then turned out to be erroneous. Apologies if I gave anyone a wrong impression of what was said.
