I have a friend who just travelled with a big knife in his carry-on by mistake. Found it in the hotel room and , was freaked out and relieved at the same time.
I have another friend who was arrested for carry on containing Foam Rubber nerf nunchucks , among his jogging shoes , jump rope and hand wraps.
" Oh, those ? They are nerf ... harmless ; look . i work out in the hotel room after hours ... "
" You are under arrest "
Double check for compliance , and be nice to the very powerful authority figures.
That's funny that they have a problem with Nerf "weapons". The few times I fly, I usually dress down for comfort, but a couple years ago I was going to my cousin's wedding, which was litterally a half hour after the plane landed, so I had to fly dressed up. The belt I wore had a 10 ounce buckle, that I've proven I can whip through two 1-inch boards (the same type used in martial arts). Two boards translates roughly to the density of a human skull. So I was allowed to bring a weapon on the plane, that could have gone through someone's skull, without much effort. I could easily break my glasses midflight and have a couple of nice shivs to stab someone with, or crack a CD in half...those can slice through skin real good. Just more proof that it's not what you bring, but instead how you present it.
I find it absolutely terrifying that someone was able to accidentally bring a knife on a plane. Literally, without even trying, they were able to sneak it past airport security. Good to know that security is doing its job.
