I'm very late to this news and am sad to discover today that Ron has passed on at the age of 87. He was Chief Pilot of Ferranti Helicopters in the mid to late 70's up until 1979 when British Caledonian took over Ferranti. The Ferranti MD Bob Smith did not continue with BCAL and Ron had anticipated he would be made MD of the newly formed company, British Caledonian Helicopters. Sadly he was shabbily treated and that did not happen. It is indeed the same Ron Salt who worked for Airship Industries after he left British Caledonian. I had the pleasure and privilige of working and flying with him as one of his pilots from '74 until the takeover and I last spoke to him in 2007. Sadly missed and my condolences to Diana.
