IIRC, Erik Prince of Blackwater fame (in fact Blackwater founder) put together the original crop duster combat planes.
He took turbine powered crop duster planes to Austria, had a firm there arm them and used them in an operation in the Sudan. The govt didn't like it.
Erik Prince is Betsy DeVos's bother. Their Dad was a major supplier of injected mold plastic parts to GM. Betsy married well in addition to having a billionaire Dad.
