This seems like an awfully complicated way to acquire an airplane. Why not just buy a used airliner through a cut-out?
Its not about the plane.
Its about the cargo and/or the passengers
OR
It is a terrorist plot to disrupt and frighten
OR
Its about a dry run
Given that The Carlyle Group and Blackstone are involved as well as employees from the company accused of spying in the US...
I think it is about the cargo/passengers..perhaps focus on the mysterious cargo container
