You forgot the part where Bing Crosby was involved in making a porno film to help the CIA to overthrow a dictator (yes it really did happen)
kind of like pulling on Superman’s cape ...
Btw, Crosby was also involved in OSS Black Propaganda programs (no, not related to Race)
Best guess...they landed the thing...transferred the suitcase bombs to a smaller plane and have been hopping from plane to boat to plane.
There's big bucks waiting at the end of the run.....but where....and where do the suitcases go from there?
The possibilities are endless.
Right now...I'd say we're doing the major tracking along with Boeing.
