Sav,
I genuinely think it was Tommy, I will do some more checking just in case my memory is playing tricks on me.
Douglas Bunn was personal friends with Alan Bristow, Alan used to have a corporate Bristow "box" at Hickstead and used to enter the carriage driving events when they were held.
Alan often used to be flown to Hickstead in a 206 from the FTS. Pilots used to try to avoid flying with him as he always wanted to take the controls (not a problem in itself, he was a good stick) but the trip to Hickstead encompassed a transit through the Gatwick Control Zone and Alan didn't like to have to hold for clearance, putting immense pressure on the pilot "in command" and his future career.
