I just learned that FAA regulations do not prohibit packing florescent and neon lights (contain mercury) in your checked and carry-on luggage when flying on an airplane (made of aluminum).
Forgive me if I misunderstand, but this is a huge gap in security, right? Broken lights would release mercury, any even a little bit of mercury could pose a structural threat to the aircraft?
Maybe the amount of mercury isn't enough to be a problem, or aircraft are hardened against this kind of thing?
@Alex It is a very very small amount, but I think the big thing is that you need to scratch the aluminum oxide layer to get it to be useful to degrade the structure: https://youtu.be/IrdYueB9pY4 (scroll to about 0:44)
