Haddenham, Cambs North of Oakington and East of Wyton.
There used to a brickworks North of the village with a tall chimney,
saw a Vampire one evening come off the fen going N-E who had to bank right to miss the chimney.
Later had the chance to see the same sort of thing from the other side, arrived back with outboard fuel in the NF10 so my driver (Pat S.) decided to burn it off running down the Solent jumping yatch masts, called it 10 mins local, all the way to Poole and back to Thorney.
