Very sorry to hear of Sandys death.
It has to be said that the guy was a genius, how he was able to recall in such intricate detail the finer points of JAR ops and airlaw I will never know. It's sad to say it but chaps like sandy are becoming a rare breed I cant imagine any of the new generation guys having the encyclopedic knowledge of Mr Thompson. (He even knew what colour the door was at ICAO head offices!)
Even during the complete mess that was the beggining of the JAR ATPL ground exams Sandy quietly soldiered on and got us the results we needed.
Always remember the unique way he used to tell stories about accidents and his dry witt "of course they all died you know".
A true Gent
