My first flight in an RAF passenger aircraft (and only my 3rd ever flight) was in an Anson of one of the last Comms Flights which still survived in 1965. Route was Catterick to Odiham and return, flown by a WW2 vintage Master Pilot. Even at that early stage I realised that I was privileged to see a part of an RAF that was soon to disappear. Aircraft don't even smell the same any more - if somebody could bottle that smell you only got in old piston aircraft I suspect they would do a roaring trade.
