Frayne Coulshaw, like myself (also called Bob btw!), was one of the 6 pilots recruited by BCalH at the time they took over Ferranti with plans of getting into the North Sea offshore market. I don't know where he is now.
Several of us were involved with helping John Hedges put together bids for offshore contracts in Europe and Africa, but didn't get in to the offices very often as they were still in Shoreham. We often got calls one evening and were asked to be in the office first thing with all the calculations complete. I lived in Sussex at that time so regularly used to fly charters in the 206. We took over the Met Police contract based out of Battersea using Bo105s whilst they were awaiting delivery of their own Bell 222s. We also had one Bo105 based in Falmouth docks for tanker pilot changes in the English channel. The aircraft used to land on a converted railway truck and was then pushed into its hangar by tractor, though passengers were embarked and disembarked from a small helipad.
I did my S61 conversion with KLM in Holland, but never flew it for BCalH on the North Sea, having left by then. Speechless and myself also did a lot of work on performance and planning figures for the Chinook as we put in a tender for the Magnus contract for BP.
