When I came home from Glasgow I had two Hugo rockets in my suitcase. Two heavy, metal, missile-shaped rockets, on an international flight. When I checked in I made sure to tell the gal behind the counter exactly what they were and exactly where they were in my suitcase. I made sure they were right on top so no-one would thing I was trying to hide anything if they happened to look in my suitcase. I asked that she please make a note in my records too. I would have preferred to have them in my carry-on, but they are considered "bludgeoning instruments" and had to go in my check-in.
