Being airworthy, and going to fly are not, unfortunately the same. Kermit Week's Mosquito is in the E.A.A. Museum at Oshkosh, where it is described as 'Airworthy', but I don't believe it flew once it was delivered to him many years ago. I suspect the Sandringham will have the same fate. I have met Mr. Weeks, nice guy, always prepared to talk aeroplanes, and I certainly applaud all he has done. I heard a rumour that he owns half of Miami Beach!!!. [I may see him at Oshkosh this year, so will ask him if this is true!!!]
