Does anyone have a better option for screening the cast once it alarms? Unwrapping it is a bad idea, but if it alarms the (notoriously over-inclusive ETD machine), what can the screeners do to rule out the presence of explosives? I don't like the conclusion of this story better than anyone who has posted in this thread, but I'm not sure I have a better solution that wouldn't allow a cast made of explosives to fly.
