Which is why I surmised the possibility of an intercept. But, what’s the likelihood of that?

Then you have to get into the FedEx and the UPS sorting plants or hi-jack the drivers on the street, take the package and ...

That's about as bad as writing your bank robbery note on your own deposit slip. (that really happened BTW)

Yeah, I agree. Someone would have to be in contact with the package between the cargo plane and the sorting plant. Not impossible, but not likely enough to be an explanation.
