OH NO, that's heartbreaking news. JBW was a legend in ABZ in the 80s as he used to come breezing into the planning room hitching up his strides.
I remember when the CB radio craze started in the very early 80s, JBW bought one and would drive between Kintore and Dyce trying to get a "copy" on CH19. Then he discovered that the Collins 618T HF radios fitted in the Bristow S-61s could be tuned to the same frequency as CH19 on a CB. Somehow the 4W AM CB Radio limit (itself illegal in the UK at the time) wasn't enough when you could push out 400w with the HF!
Bless you my old friend, I had no idea you were suffering so much.
Cornwall and the helicopter industry have just lost one of their true treasures.
