Called in at Duxford a couple of weeks ago after my return to France delayed by striking (could think of another adjective) air traffic controllers, and was treated to flying by Catalina, Hurricane, Spitfire and Blenheim (including an ashes scattering that at first led us to think there had been an engine failure) together with usual Rapides and Tiger Moths, and was amazed by the number of people who apparently have just shy of £3k for half an hour in the back of a 2 seat Spitfire.
