Has anyone had any experience getting rockets and/or engine casings through airport security? I can imagine that a full 3' rocket (even in pieces) appearing on an X-Ray might raise a few eyebrows, but a couple of empty engine casings might get through ok. They probably have AP residue, although I could thoroughly wash them beforehand. Nothing about rockets is explicitly forbidden on the TSA website.
I may have to declare the items, such as when people take firearms on an airplane. As long as they don't call the bomb squad and blow up my luggage, the worst that could happen would be missing my flight. Thoughts?
