Buying aeroplanes, large or small, has always been one of the most effective ways to move 'money' around the globe and obscuring the ultimate ownership of an aircraft (or even a fleet) is fairly straightforward. It's a lot easier to move a plane from one jurisdiction to another and flog it, than it is to move that house in Eaton Square. Many a billionaire have had stakes in all facets of aviation - airline fleets as well as business aviation assets. Ultimate mobile investment. Better than boats too.
