Mine comes from when I was a child. This was during the period after the initial phase of hijackings. I was moving with my parents cross country to a naval base in California. It was my first airplane flight. I had my most prized possessions of the time as a carry on: a metal suitcase style Fort (with cowboys and indians.) Since I was about 9 at the time I also had my favorite set of metal pop gun pistols in it as well...fairly large and quite realistic looking. Needless to say, the Fort ended up flying with the other baggage. I can't imagine what would happen today. Do they give 9 year olds cavity searches?
