Very sorry to hear of their demise. I can remember meeting the proprietors years ago at Cranfield when they were just in the process of replacing old Nabarro of Avigation - with whom I did my CPL writtens. I did my ATPL with the outfit and then some bolt on bits when I started to aspire to fly pressurised jets. They will be sadly missed. There is certainly a niche market out there for somebody, unless the implementation of this wretched JAR has removed the requirement which they and Avigation before them filled so successfully for so long.
