Most airline passengers pack a toothbrush and fresh underwear in their luggage, others land mines, grenade launchers, swords, mortar shells and martial arts spikes and stars. Not only does the Transportation Security Administration confiscate four handguns a day from airline customers, its agents have also seized a stun gun concealed as a tube of lipstick, a dagger hidden inside a hairbrush and a whole host of other weapons and contraband taken from passengers on a daily basis, according to weekly updates on the TSA Blog.
