Thank you, Fl1ingfrog, but it's the historical issues that I'm hoping to trace. If it was the CAA that pulled the plug on GASIL, it's unlikely that it will have uploaded copies of these to a website. But there's the remote possibility that someone else, with or with access to a comprehensive run of the bulletin, may have done so out of public spiritedness. However I think that I'm at the 'highly improbable' end of 'remote possibility'!
