Postscript....

While having lunch just now a Seafire flew over the house (the marine cousin of the legendary Spitfire from WW2). It was heading for Henstridge Airfield about 2 miles away, so we watched it from the garden. Photo isn't great as hand held at a distance, but what a gorgeous sound as those Merlin engines waffled and warbled, unlike anything else in the history of Aviation .... Yes I know it's not a bird, or a real Merlin, but one fabulous flying machine.
