You put it together and toss it in any baggage you intend to check (wouldn't want to mess with the TSA at the passenger entry points ~ they might come unhinged).
With enough bags and enough boxes doing nothing but showing up on Xrays, that should slow down civil aviation to a snail's pace.
Another box would be plain cardboard wrapped with aluminum foil duct tape.
huh?
Who didn’t see this coming?
