Only just come across this thread. I was also at Upavon 1970-73 when the AOC in C was Sir Harry Burton. I worked directly for Sir Harry and Lady Burton and they were a wonderful team. John Reed and Derek Copins were the crew on his Pembroke and we had great fun visiting the various Air Support Stations. I was very junior but it was a great headquarters to work in and Upavon was a splendid station. Very happy memories.
