The Spitfire owners would have had to shell out an astonishing £50,000 to cover their brief flypast, which was due to take place over central London on September 20.
Paul Beaver, who was organizing the event, told the Daily Telegraph: “The route we were going to take would have made sure there was always somewhere for an aircraft to land if it got into difficulties, and usually the individual owners’ aircraft insurance, which provides £5 million of third party cover per aircraft, would have been enough.
