I apologise for coming so very late to this thread - but I only found out yesterday that Sam had died, and I'm feeling profoundly saddened. Belated condolences to his family and friends.
I knew Sam 10 years ago when he was an instructor at Fast Helicopters in Shoreham; I was a newly-qualified ppl at the time. He really helped me out with the scary world of xc nav - without Sam, I'd have never gone to Wellesbourne...
Great guy, sadly missed.
Cheers
Jimmy
