I thoroughly applaud this native reserve but I do wish such celebrities would lend a hand to help roll back some of the serious government pressures on GA which would prefer you didn't fly more than 10k from your home field and even then would want you to fill in forms in triplicate
Someone who hasnt been listed I dont think (and depends on your definition of the word "celebrity"), and may be your man, is Grant Shapps, who as well as flying a Saratoga, is the chairman of the UK Conservative party. There have been postings here and elsewhere about the governments red tape challenge, which I think Grant was 'chairing' on behalf of GA. Not sure what or if anything became of that.
