You could always try Langley or one of their myriad shell companies in Delaware, U.S.A. Although the old girl is actually registered in Louisiana.
It is not a CIA or any other type of government 'shell' company. The name of the owner is Earl Cherry. He is a former corporate pilot and airshow aerobatic performer, performed in a 450HP Stearman with a wing walker. And yes, he lives in and comes from Louisiana.
We used to fly together.
No, I was not the wing walker.
