I had no idea, I'm very sorry indeed to hear of this; I'd lost touch with him some years ago. I served and flew with Chris on 230 Sqn at Gutersloh over three decades ago and he was a very good crewman and crewman leader, and a good mate, too. Boy, did we have some good parties in his MQ cellar bar back then!
RIP, old chum. My heartfelt condolences to those close to him.
