Very sad to hear that. My wife & I shared a house with Rupert & his wife in Singapore in the mid 60s when we were both in the Royal Navy. Since then in recent times thanks to Pprune we regained contact; he always sounded happy with his new life in the Far East.
As Mr Toad he was often on Pprune; far too young to move on. His wife, Alice, started a restaurant in Melaka about 2 years ago & Rupert used to commute to the flight sim in Farnborough. It's sad his retirement didn't last longer.
RIP & all the best wishes to the family
